Adhesive Application Spread adhesive using a notched trowel to a minimum bedded thickness of 3 mm on walls and 5 mm on floors. Heavily lugged, grooved or dove-tailed tiles must be buttered to fill any voids with adhesive before placing into wet adhesive.

28 days 28 days 28 days 28 days

Press tiles firmly into wet adhesive with a twisting action. Use a rubber mallet to bed large or heavy tiles. Occasionally lift a tile to check that full contact is being made between the tile and the adhesive. Do not butt joint tiles.

The walls or floors to be tiled must be wood-floated and not steel-trowelled or power-floated. Ensure that all surfaces are clean, dry, sound and free from dust, grease or any contamination that could impair bonding. Make good any unsound areas and remove flaky or peeling layers before tiling.

Clean excess adhesive off the surface once tiles are firmly set using a damp sponge. Once the adhesive has hardened, only mechanical removal is possible.

Organic growth must be removed and the spores killed using household bleach. PVA paint and gypsum plaster must be chipped to expose more than 80% of the substrate. Enamel paint and bitumen should be scraped and chipped to expose more than 80% of the substrate. Do not use a solvent or heat to remove bitumen from the surface. Existing tiles must be thoroughly cleaned using a suitable cleaner. Rinse with water. Smooth-, off-form-, shutteror power-floated cement surfaces should be acid washed to remove laitance. Rinse well with water. Once the Surface Preparation has been completed, prime the area using a mix of 2 volumes of Plaskey and 1 volume of Key‑it. Apply to a thickness of approximately 2 mm using a block-brush. Leave to dry for 24 hours.

Grout General Information Technical Figures Figures are approximates and obtained at a temperature of 20oC and relative humidity of 50%.

Storage & Shelf-life Shelf-life is 9 months from date of manufacture when stored unopened, in a dry place and above 5oC.

Safety Instructions Contains cement, which is alkaline when wet and can cause skin irritation. Use eye protection and gloves and avoid prolonged skin contact. Avoid inhalation of dust. Wash skin contamination away with warm soapy water. Remove splashes to the eyes by prolonged irrigation and consult a doctor. Do not ingest.

Grouting Ensure that the joints are free from tile adhesive and any other foreign matter. Allow 24 hours before grouting with Tile Grout and 6 hours for Acid-resistant Tile Grout.. Allow 48 hours for sealed or non-porous surfaces. In wet or permanently wet conditions, replace the water in the mix with Bond‑it.

Please note Some tiles may have a softer surface which can be scratched during grouting. Tiles with a matt or porous texture are prone to surface staining when coloured grouts are used.

kg/m2 = Do not leave excess moisture on grout joints. The joints can be finished off by pointing along the joint lines. Allow the joints to dry for 2 hours before polishing with a clean, dry cloth.

Mixing 1 Mix with 1.35 litres of clean water per 5 kg bag to produce a thick creamy paste 2 Allow the mixture to stand for 5 minutes 3 Remix thoroughly before use 4 Do not add too much water or attempt to extend the working time Application Using a squeegee or rubber float, apply grout liberally to a small area. Completely fill the joints leaving no voids. Excess grout should be removed immediately using the grout squeegee held at 90o to the tiles. Move the squeegee diagonally across the tiles to prevent removal of the grout within the joints. Leave the grouted joints to harden over the recommended time. The excess grout can then be cleaned off with a damp (not wet) sponge.

Note When using a grout that is a similar colour to the tiles, it can be difficult to see any residue that is left in these shallow depressions. It is recommended that these tiles be treated with an appropriate protective sealer that helps to stop the grout sticking to the tile face. It is advisable to test the grout on a spare tile before proceeding. Do not add too much water or attempt to extend the working time by adding more water as this will cause the set grout to be weak with a tendency to crumble and may cause discolouration.

Coverage Use the following formulation to calculate the quantity required per square metre of tiling:

The use of an appropriate protective sealer is recommended before grouting. Natural stones such as limestone, marble, slate, sandstone and terracotta, will require sealing prior to grouting.

Surface Preparation The minimum joint width is 2 mm for walls and 3 mm for floors. Do not butt-joint tiles. Adhesive should be left to dry for at least 24 hours before grouting. If a rapid-set adhesive is used, kindly follow the instructions. Longer drying times may be required on sealed or impervious surfaces. Ensure that the tiles and joints are clean and free from grease or any other contamination. It is advisable to moisten the joints before application to assist the flow of grout into the joints.

Weber Solution

Achieving a Suitable Adhesive Bed

Using the appropriate trowel helps to ensure that an even layer of adhesive is achieved and leaves ribs that allow for adjustment of the tile height.

The adhesive bed performs a number of functions: it sticks the tile to the surface; it absorbs differential movement between the substrate and the tiles; it protects the substrate from water; it absorbs deflections; it enables the tiler to adjust the height of each tile; it accommodates limited errors in the substrate.

Voids behind the tiles allow access to any water that penetrates the grout This can cause a damp, musty smell in showers. Any water leaks are made worse by having channels available for water to run through. Externally, any trapped water can freeze and the associated expansion can push tiles off.

Voids leave floors susceptible to point loads Ceramic tiles are inherently brittle and therefore any area of the tile that is not fully supported is vulnerable when subjected to a localised load. Examples could be: a chair leg, something being dropped, or any heavy item on small feet such as a kitchen appliance.

Use a suitable notched trowel For wet areas, exterior areas and all floors, it is necessary to achieve a solid bed of adhesive under the tile. The adhesive should be applied in a consistent manner using the correct type of trowel. When applying on walls, the adhesive should be applied in horizontal parallel strokes for dry areas, and vertical strokes for wet areas. Do not apply in swirls as this causes air pockets to form. The tile should be pressed into place with a twisting and/or sliding action to ensure a good contact with the adhesive. It is recommended that during tile fixing, an occasional tile is lifted back up, to verify that the desired contact is being achieved. Walls in exterior or interior wet areas Notched trowel: 8 x 8 x 8 mm Wall tiles in interior dry areas Notched trowel: 6 x 6 x 6 mm Mosaic tiles Notched trowel: 6 x 6 x 6 mm

The thickness of the adhesive bed is also important If the adhesive bed is too thin, a cement-based adhesive may dry out very quickly and not gain strength and structural integrity. In the case of floors where some movement is expected, the adhesive is required to give, and its ability to do this is severely limited if it is applied too thinly.

Variations in the adhesive bed will show through some tiles Some tiles and natural stones will show an adhesive shadow on the face of the tile, where the adhesive is in contact with the tile. Voids behind the tile may be visible from the front of the tile. Areas where there is no contact between the tile and the adhesive bed will not be bonded. A 50% contact will therefore result in only 50% of the overall bond strength across the tile.

Floors Notched trowel: 10 x 10 x 10 mm Solid finished bed 3â&#x20AC;&#x201C;6 mm deep Large tiles If the tiles are very large or have large studs or ribs on the back it may be necessary to back-butter the tile as well as spreading the adhesive on the substrate.

Prevent Picture Framing, Staining & Grime Build Up

The correct techniques for protecting and increasing the life of natural stone. It is necessary to use not only the correct materials but also the correct techniques to protect, enhance and maintain natural stone. If these techniques are not used, stone could be damaged or stained which would destroy the natural beauty and effect of the stone.

Natural stone tiles can be very porous or textured and because of this, careful preparation is required prior to grouting to stop damage from occurring. Once in service, natural stone will also need regular maintenance to keep it looking in top condition.

Picture framing, staining and grime build-up Modern grouts are often polymer-modified and can be very fine. Although this offers many benefits, such as better flexibility and increased strength, it can also mean they are harder to remove from tiles and more likely to stain natural stone. Picture framing’ or ‘Tram lining’, as it is often referred to, is a description used when a cement film has dried around the surface edge of a tile. The main causes for this are: • Point grouting into the joints rather than slurry grouting the whole tile. • Leaving excess grout on the tile for longer than recommended by the manufacturer, causing a chemical etch due to the pH level of the cement. • Capillary absorption from porous stone drawing the grout into the surface. • Excessive water being used in the grout. Textured or porous natural stone are particularly susceptible to these problems.

Grout and Stone could stain when in service When the grout and tiles have been in service, they can be prone to staining if they have not been cleaned correctly. The tiles should be adequately sealed prior to being put into service.

Without maintenance, tiles can lose their effectiveness Regular use and/or general build up of grime can mean that natural stone loses it’s ‘wow’ factor. With careful cleaning and maintenance the natural beauty of stone can be kept for many years with only minimal expense. The use of the wrong cleaners can lead to a soft waxy build up or, even worse, damage to the surface of the stone.

1 Cleaning prior to grouting Prior to grouting, check tiles are clean and dry. If the tiles need to be cleaned to remove dust, dirt or footprints, a pH neutral cleaner must be used. This will remove the marks without damaging the surface of the stone (if there is a small amount of adhesive residue on the tiles, a specially formulated cleaner, with a higher pH may be needed). 2 Protection of the stone prior to grouting Once the stone is clean, it needs to be prepared for grouting. The surface of natural stone can be very porous and textured and if it is not prepared correctly, can be stained during the grouting process. To aid the removal of grout and to reduce the chance of staining, a suitable natural stone impregnator should be applied to the surface of the stone using a roller or sponge. This should be worked into the surface slowly to maximize effectiveness and to minimize frothing. After 4-6 hours, the tiles should be dry enough to grout. 3 Grouting Grout should be applied liberally and worked across the whole surface of the tile, not just along the joints. This will help minimize the ‘picture framing’ effect that is achieved when point grouting. Excess grout should be removed from the surface of the tile within 5-10 minutes. If any excess grout is left on the tile surface, it should be removed with the help of a specially formulated cleaner. 4 Final protection of the grout and stone Once the grout is completely dry, preferably left over night, another coat of natural stone impregnator should be applied over the tiles and grout. This should be repeated until all the surfaces are saturated and do not absorb any more impregnator. Once the stone and grout has dried it will be resistant to staining and easy to clean. 5 Maintenance For regular cleaning a good quality cleaner should be used. This will prevent long term damage to the stone, sealant and grout. A good quality cleaner will contain cleaning components and enhancing agents that will make the surface richer. Any cleaning product containing wax should not be used as they promote a build up of false layers that will spoil the floors appearance in the long term.

Floor Tiling with Large Tiles

Ceramic S & L Porcelain S & L Ultra-Flex

The use of larger tiles has become a common practice. This has placed extra burden on the adhesive used, which needs to be highly flexible and allow for easy bedding.

Substrates move slightly with changes in temperature and moisture and structural movement When a substrate expands or contracts even slightly, due to changes in temperature or water content, the tile being of a different material will change by a different amount. This can arise for a number of reasons, for example: • • • •

Shrinkage in a screed as it dries Thermal expansion in hot weather Moisture-induced expansion on getting waterlogged Thermal cycling of under-floor/ under-tile warming systems

Larger tiles suffer higher strain levels than smaller tiles • The increase in strain is cumulative across the width of the tile i.e. the further a contact point is from the centre of a tile, the more adjacent points in the tile and the substrate will be stretched away from each other. • So for a given set of circumstances, a smaller tile will be less likely to delaminate than a larger one.

Large tiles are placed under more stress by any deflection in the floor • When a non-rigid substrate deflects, the rigid tile cannot withstand the deflection. • For a given deflection in the substrate, the chord height that the tile tries to bridge will be higher for larger tiles. • This results in higher stresses and therefore requires greater flexibility in the tile adhesive to prevent failure when fixing larger tiles.

08 09 12

Substrates: It is necessary to select an adhesive with the appropriate level of flexibility to accommodate the expected strains from either differential thermal or moisture movement and/or deflection of the substrate under load. There are many possible permutations, so we have indicated some guidelines below.

Rigid substrates Sand or cement screeds & concrete. Ceramic up to 420 x 420 mm – Ceramic S Ceramic greater than 420 x 420 mm – Ceramic L Porcelain up to 600 x 600 mm – Porcelain S Porcelain greater than 600 x 600 mm – Porcelain L Substrates with limited movement Over-boarded wooden floors, screeds with under-floor heating. Tiles up to 400 x 400 mm – Ultra-Flex Important note With larger tiles, the force needed to bed them correctly increases dramatically. If 2 kg of force is needed to bed a 10 x 10 cm tile, 32 kg is needed to bed a 400 x 400 mm tile. It is therefore very important that the correct trowel, method and adhesive are used. Specially developed adhesives such as the Ultra-Flex, help achieve a solid bed, even on large tiles.

Impervious Tiles or Substrate

Ultra-Flex Additives & Surface Preparation

Highly polymer-modified adhesives achieve a sound chemical bond onto impervious surfaces overcoming the need for suction and mechanical keying.

When tiling an area that is already tiled or painted, it is often necessary to invest considerable time in stripping and then repairing the substrate. In certain situations it is more convenient to tile over the existing layer. However, this requires careful consideration and an adhesive with exceptional properties.

Standard cement-based tile adhesives won’t stick to a completely smooth surface Standard cement-based tile adhesives rely on a mechanical keying action to bond onto the substrate. The wet cement engages physically with small irregularities, pores etc in the surface and uses this to form a strong bond. When the surface is very smooth this grip is reduced resulting in tiles de-bonding. Existing ceramic tiles and paint are examples of such surfaces. The back of very low porosity tiles, such as porcelain, is another example.

These types of surfaces are largely impervious to water and this results in a longer time delay before the water from the adhesive can escape the system Ready-mixed adhesives are dispersions of polymers and inert fillers in water and do not gain strength until the majority of the water has dried out. With large tiles on impervious surfaces, this can take weeks. At lower temperatures, even standard cement-based products can take several days to set and dry. The other complication from slow extended drying, is that if the joints are grouted before the drying is complete, the water will be trapped. As it subsequently permeats through the grout, it will bring dissolved salts from the adhesive or grout and cause a white deposit on the surface of the grout, known as efflorescence. As much as there is always a possibility of this happening, the chances are increased the more water that is trapped. Tile directly onto well-adhered ceramic tiles or paint or with low porosity tiles.

Stage 1 — Assess and prepare the floor/wall It is essential that the layer that is to be tiled over is completely clean and able to withstand the extra weight of another layer of tiles and adhesive: • Gypsum plaster can only support 20 kg/m2 and plasterboard 32 kg/m2 – the weight of both tiling layers must be considered. • The bond strength of any paint may well be the weakest link. Epoxy paints on floors and gloss paints on walls are usually strong enough but emulsion paint is not and should be removed mechanically. • If the existing layer is over something flexible, such as wood or a heated screed, then this level of flexibility will be required of the new tile layer and the adhesive specification may need to be upgraded. • If possible, lightly abrade the surface with aluminium oxide or carborundum paper to improve the mechanical key. • Ensure that any traces wax, polish, grease, dirt, dust etc are completely removed from the surface. Stage 2 — Fix the tiles Fix the tiles with a polymer-modified adhesive: • For solid and floors use Ultra-Flex • For heated floors use Ultra-Flex • For wooden floors use Ultra-Flex A solid bed of adhesive is recommended to maximize the strength of the bond. Stage 3 — Grout Leave the adhesive longer than normal before grouting to allow the water to escape the system. This will be longer for larger tiles. Grout with a grout that is suitable for the area concerned. Use a suitable flexible sealant for the perimeter movement joints.

Tiling on Floating Floors

Overboard with plywood or tile backer-board. Tile Grout Bond-it

22 53

Floating floors is a term used for a floor that is not attached to a rigid substrate. Generally this will be a tongued and grooved wooden board above an acoustic or insulation material. Floating floors are used to improve floor insulation and or to reduce noise transmission. Normal wooden floors flex when loaded but this movement is even greater on a floating floor as the boards are not supported by joints.

Deflection • As a floating floor is not supported by joints, any applied load creates significant movement over a big area. This can be felt as bounce in the floor when it is walked across. As the applied load increases so does the severity of movement. • The edges of a floating floor are even more susceptible to exaggerated movement as they are not supported and any applied load is spread over a smaller area. If the adhesive used to fix the tiles is not flexible or thick enough to absorb the amount of movement, the tiles will either delaminate or crack. Large tiles will exacerbate the deflection across each tile’s width.

Unsupported joints • Deflection (bending) of the floor • Unsupported joints causes cracks in tiles over joints. • Columns created by nails fixing overboards to floating floor. The loose nail pushes up against the tile and cracks it from behind. • If a joint between wooden boards of a floating floor is not correctly located or fixed, it will be susceptible to highly localised movement which will crack the tile along the joint. If the boards of a floating floor are not tongue and grooved, they are not suitable for tiling.

Columns When a floating floor is over-boarded to add rigidity, the extra board has to be securely attached to the original boards. If nails are used, the constant movement of the floor can cause them to work loose, press on the underside of the tile and cause cracks. If the screws/nails used are too long they can bottom out on a rigid surface under the floating floor and create a column, over which tiles will crack.

Step 1 — Preparation Verify that the extra height from the over-boarding can be accommodated and that the floor is capable of supporting the expected load. All tongued and grooved boards should be glued together securely and wedged around the edges until dry. Step 2 — Fix the over-boarding Use plywood at least 15 mm thick. Lay the boards so that the joints do not coincide with joints in the existing timber and leave slight gaps between boards to allow for expansion. Screw the boards at 200 to 300 mm intervals. Leave a movement joint around the perimeter for expansion. Step 3 — Fixing the tiles Fix the tiles into a minimum 5 mm solid bed of Ultra-Flex. Leave joints at least 3 mm wide for grouting and make adequate provision for movement (around the perimeter) and dividing large areas into bays. Leave the adhesive to set and then grout the tiles with Tile Grout mixed with Bond‑it only. Note: Use a suitable silicon or polysulphide soft joint for perimeter joints.

Tiling on Uneven Surfaces

Plaskey Key-it Self Levelling Screed WB270 Ultra-Flex 4602 Industry-Base Extra

It is important, both for appearance and for safety, that the finished tile surface is flat with no tiles standing higher than the others. Providing ‘normal’ tiling practices are followed, this is straightforward on flat, level substrates. If the substrate is however not flat, then a number of problems can arise.

Increased difficulty in achieving a flat finished surface on the tiles A serrated adhesive spreading trowel, when used at a constant angle, enables the even distribution of adhesive onto the substrate. If the tiles are all bedded with a similar force they should be at the same height with only minimal unevenness. However, if the substrate is not level, this is much more difficult to achieve and there is more chance that some edges will be standing proud.

Extra time required to fill multiple holes Localised deep holes may result in a bed thickness that exceeds the specification for a thin-bed adhesive. Patching such holes can be time consuming if there are more than a few of them.

56 52 95 12 92

Use the appropriate flexible adhesive There are a number of possible solutions depending on the condition of the substrate. A levelling compound will give a smooth surface but this does not help with Uncalibrated stone, where a high-build adhesive must beused. Deep holes should be filled first with a repair mortar.

Solution 1 — Use a levelling compound A levelling compound can be used to smooth out irregularities, holes and gaps between existing tiles etc. and provide a flat and level surface for tiling. Ensure that the surface is clean, dry and sound. 80% of a painted surfaces must be chipped. All existing tiles must be firmly adhered. Thoroughly prime with Plaskey and Key‑it. Pour the appropriate levelling compound to the required thickness using Self Levelling Screed WB270 floor from 1 to 20 mm. Make sure that any movement joints in the substrate are carried through the screed and tiling layer. Fix the tiles using a Weber cement-based adhesive as appropriate for the type of tile. Allow the adhesive to set fully and then grout the joints.

Combination of problems In some instances, for example when tiling over a layer of existing ceramic tiles, the above mentioned problems may be combined. Some tiles may need to be removed because they are unsound, whilst others may have been imperfectly fixed and exhibit some variation in height.

Solution 2 — Use a thick bed adhesive If the tiles/stones are Uncalibrated, a thick-bed adhesive must be used. This will also allow for some irregularities in the substrate. Ensure that any loose or unsound material is removed. Fix the tiles with Ultra-Flex thick bed adhesive, which can be built up to 25 mm thick. Allow the adhesive to cure for at least 24 hours before grouting the joints.

Some natural stones are not a constant thickness Uncalibrated natural stones are stones that have been split along natural fracture planes rather than machine cut. The result is a stone that varies in thickness, both from within each stone and from piece to piece. These types of stones require an adhesive that can be applied to greater thickness than normal.

Solution 3: Use a patch repair mortar For occasional deep holes in an otherwise flat surface, a repair mortar may be the best option. Ensure that any loose or unsound material is removed and that the area is cut square and not feathered. Fill the hole(s) with 4602 Industry-Base Extra compound and allow to cure. Then fix the tiles using an appropriate weber tile adhesive. Allow adhesive to cure fully before grouting the tiles.

Tiling onto Wooden Surfaces

Quick Set 6

Solution 1 Overboard with plywood or tile backer-board Solution 2 Tile directly onto tongue & groove boards and sheets

Timber floors and ceramic tiles are not natural bedfellows – tiles are inherently rigid and brittle whereas timber floors are flexible. There are many types of wooden floors but in principle the challenges that they present to the tiler are all the result of this mismatch. There are a number of contributing sources of movement in timber floors which need to be considered when fixing ceramic tiles or natural stones.

Solution 3 Tile directly onto non tongue and groove sheets

General deflection due to the applied load The floor will deflect according to the load applied and the stiffness of the structure (joint size, spacing etc). If the adhesive is not flexible or laid thick enough to absorb the amount of movement, the tiles will either delaminate or crack. Large tiles will exacerbate the deflection across each tile’s width.

Solution 1 — Overboard with plywood or tile backer-board The most secure system for tiling wooden floors is to screw-fix another layer of boarding over the top of the original timber. This increases the rigidity of the floor, helps prevent localised movement, and if a water-resistant tile backer board is used, it virtually eliminates moisturerelated movement.

Localised movement at unsupported board joints & Creaking in certain places as you walk on the floor Any inadequately supported joint will cause a highly localised movement which will crack the tile. Joints may be supported by joists, noggings, or each other’s tongues and grooves.

Solution 2 — Tile directly onto tongue & groove boards and sheets It is possible to tile directly onto tongued and grooved wooden floors by using a highly polymer-modified adhesive, providing that the floor is rigid enough and the tongued and grooved joints provide effective support. If the tiles are larger than approximately 400 mm square, over-boarding is recommended (See Solution 1).

Solution 3 — Tile directly onto non tongue and groove sheets If the floor consists of sheets that do not support each other, it is necessary to ensure that each edge is fully supported underneath. If the tiles are small (not more than 400 x 400 mm) Quick Set 6 is adequately flexible. Temperature related expansion and contraction Wood expands and contracts with changes in ambient temperature at a different rate to mortars, ceramics and stones. As a further complication, timber expands much more across the grain than it does along the grain (this is not really a factor with manufactured boards such as plywood).

Moisture/humidity related expansion and contraction Wood swells if it gets wet even with changes in atmospheric humidity. This can be a problem in potentially wet areas such as showers and bathrooms and also if the wood is not dry when installed (e.g. if it has been kept outside).

Tiling onto Plastered Surfaces

Plaskey Key-it

Plaster is a very common interior substrate that generally provides a good, flat surface for tiling. There can be, however, certain problems associated with plaster and these need to be overcome with correct preparation and application.

Plaster can only support relatively small / light tiles 1 Plaster is a relatively weak material (in comparison to wood, brickwork, concrete etc). The maximum weight of tiling which can be supported by a dry, well-adhered plaster bac kground, is 20 kg/m2. 2 New plaster work should have been completed at least 4 weeks prior to tiling commencing. Even if the surface appears to be dry in less than 4 weeks, the layers underneath will not be.

Plaster is water sensitive Plaster is water sensitive and is therefore not an ideal substrate in areas subject to wetting such as showers or wet rooms.

The finish quality can be very variable Plaster finishes, when prepared for tiling, should be finished in accordance with the recommendations given in SANS 50197 and SANS 50413 Class MC12,5 X*. Very often the finished surface of plaster can be very variable, depending on the conditions and the plasterer. The surface can be very dusty or, if overtrowelled, it can be very dense and shiny.

Cement adhesives react with plaster When plaster comes into contact with cement it forms a weak layer of laitance (cement calcium surface residue ettringite) that can cause the adhesive and plaster to not adhere to one another. Careful preparation is needed to stop this happening.

* See SABS website: www.sabs.co.za

Plaster finishes, when prepared for tiling, should be prepared as recommended in SANS 50197 SANS 50413*. Quite often though, the finished surface can be very shiny or dusty and this needs to be prepared correctly prior to tiling, otherwise failures could occur.

Tile size and thickness The maximum weight of tiling which can be supported by a dry wall-adhered plaster bac kground is 20 kg/m2. This is including the adhesive and grout. A good guideline is that tiles should be no thicker than 8 mm if they are ceramic, or 7 mm if natural stone. Where thicker/heavier tiles are to be used, plasterboard (up to 32 kg/m2) or tile backer (see manufacturerâ&#x20AC;&#x2122;s recommendations) should be installed. Protecting plaster substrates when subjected to wetting Plaster loses nearly all its cohesive strength when wet so it needs to be protected in areas where it could be subjected to wetting such as showers or wet rooms. An easy to use tanking system such as Plaskey with Keyâ&#x20AC;&#x2018;it will protect the plaster and provide a suitable substrate to tile onto. Preparing the surface prior to tiling Sometimes the finished surface of a plaster substrate is not ideal for tiling. If the surface of the plaster has been over-trowelled it will be very dense and shiny and this will make the bond with the adhesive very weak. It is recommended that the surface is abraded with a stiff wire brush and then all dust removed prior to tiling. If the surface of the plaster is dusty, it should be wiped with a damp cloth until all dust has been removed. Using cement-based adhesives on plaster If cement-based adhesive is being used, the surface of the plaster must be sealed to stop the cement reacting with the plaster and forming a weak layer of ettringite which could cause the tiles to de-bond. It is recommended that Plaskey or Keyâ&#x20AC;&#x2018;it is applied to the surface until the plaster stops absorbing.

Tiling Showers, Bathrooms & Wet Rooms

Waterproof-It Shower Ceramic S & L Porcelain S & L Tile Grout Acid-resistant Grout Bond‑it

Showers, bathrooms and wet rooms are very common applications for ceramic tiling. The tiles themselves are not really affected by the action of water but the overall installation can be. The fixing materials must be chosen to suit the level of exposure to water.

Adhesives and grouts are porous Most cement-based products including grouts and adhesives are porous to some extent. They have minute voids left by the evaporation of un-combined water or by gaps between the aggregates. These pores allow water to permeate through the grout into the adhesive and substrate.

67 08 09 22 20 53

There are too many possible combinations of products to list so below are three main levels in a hierarchy of water resistance based on the fact that: 1 Paste tile adhesives are less resistant than cement-based adhesives. 2 Standard grouts are more porous than modified grouts, which are more porous than epoxy grouts. 3 Gypsum plaster and plaster board are more affected by water than cement-plastered walls, both of which are even better when tanked.

• •

• • Voids in the adhesive layer allow access for water Voids left in the adhesive layer after bedding the tiles will allow any water that penetrates the grout or sealant to gather. If this water has nowhere to escape to it may encourage mould growth. Alternatively the trapped water may run along channels left in the adhesive bed and leak out at a different point to its entry.

•

Some substrates are affected by water Some substrates, particularly gypsum plaster and plasterboard, have very little strength when wet. Continued water ingress will over time cause the substrate to fail.

• •

•

Paste Adhesives have limited resistance to water Most ready-mixed adhesives are water-based. They set by allowing the water to dry out and form a strong hard bond. However, when they are exposed to water they tend to weaken. Some are more resistant than others but almost all are affected eventually.

Specialist Tiles

Tile Grout Mosaic-Fix Weber White Bond-it

Generally, the three most common types of tiles used are ceramics, porcelain and natural stone. Occasionally though, other more specialist tiles are used on jobs and these quite often require special adhesives and preparation.

Mosaic Tiles Mosaic tiles can be made out of a variety of materials from glass to natural stone and can be supplied in a variety of shapes and sizes. The mosaics are supplied on sheets for ease of fixing and these sheets are usually in 2 forms, face down on paper or face up on synthetic mesh. If the mosaics are supplied on synthetic mesh, the mesh and mesh adhesive should not cover more than 25% of the back of the tile otherwise it could affect final adhesion.

Glass Tiles Glass tiles are becoming more popular, especially in more modern designs. They do, however, cause some application problems. Glass, by its nature, is very smooth and non-porous meaning it can be difficult to adhere to. Also, when frosted glass tiles are used, grouting can leave unsightly marks on the surface which are very hard to remove. If a dark adhesive is used with glass tiles it can show through as a shadow on the tile body.

Metal or Metallic Tiles Metal tiles come mainly in two forms. These are either sheet metal or metal formed around a solid bac kground such as tile backer-board or MDF. These tiles are often pressed so have a textured surface which causes problems when grouting. Metallic tiles often react with cementitious grout and tend to discolour unless the correct product is used.

Resin Tiles Resin tiles can come in all sorts of designs, shapes or sizes. Nearly any design can be made to make a feature in a house or commercial project. Resin tiles can be very smooth and can be very difficult to adhere to.

22 13 10 53

Use the correct methods, adhesives and grouts. The outstanding aesthetic qualities of certain specialist tiles can often hide the fact that extra care will be needed when fixing. Generally, the backs of specialist tiles can be very dense or smooth thus meaning that higher grade adhesives are needed to bond the tile sufficiently.

Mosaic Tiles Mosaics which are face down on paper should be pregrouted from the back prior to fixing onto the wall. This will result in a smooth, flat grout joint. Tile Grout is ideal for this as it is very easy to use. Starting at the top, a 6 x 6 mm tiling trowel should be used to spread Mosaic-Fix onto a small area and the mosaic sheet pushed into the adhesive bed. To help achieve the desired contact area on the back of the tile, a flat trowel can be used to push or tap the mosaics into the adhesive. Mosaic-Fix should be used for floors and for walls. Mesh-backed tiled should also be applied in a similar fashion but should not be grouted until the mosaics are in place and the adhesive set. When a section of pre-grouted paper-faced mosaics is in place, the paper face should be moistened with a wet sponge and peeled off. Any final adjustments should be carried out prior to the grout and adhesive setting. Glass and Resin Tiles Glass and resin tiles have very smooth non-porous backs that are difficult to adhere to so usually require a highly polymer-modified adhesive such as Weber White. This adhesive gives excellent adhesion and also reduces the stresses caused by differential thermal/moisture movement between the tile and the substrate. Tile Grout is available in several colours to match or contrast any tile design. Frosted/rough surface glass tiles can also be very difficult to clean after grouting and will require extra cleaning to remove the grout residue. Grout should not be allowed to dry on these tiles as it can cause staining. It is advisable to carry out a test on a spare tile before grouting. Metal or Metallic Tiles Weber White should be used for metal tiles that are formed around a backing block such as resin backed filler MDF, ceramic tile base. This adhesive gives excellent adhesion and also reduces the stresses caused by differential thermal movement between the tile and the substrate. Solid metal tiles are usually made from thin sheets of stainless steel and they should be adhered and grouted with Tile Grout in conjunction with Bondâ&#x20AC;&#x2018;it.

Tiling Swimming Pools

Plaskey Key-it Bond-it Ceramic S & L Tile Grout Acid-resistant Grout Quick Set 6

Swimming – and other types of pools are the ultimate wet areas for tiling. It is important to specify the appropriate materials to achieve a durable installation. Once filled, it is not easy to make significant repairs without taking them out of service for long periods.

Immersion in water requires adhesive unaffected by water In a pool, water is almost certain to penetrate the grout joints. Cement-based grouts are porous and allow water to soak through. Even when an epoxide-resin grout is used, it cannot be guaranteed that all of the joints are perfectly filled. The consequence is that: • The bond strength of the tile adhesive must not be affected by continuous immersion in water. • The pool must have a waterproof shell or layer behind the tiles.

Initial movement due to weight of water and heat The pool will be tiled when it is empty. Once the pool is filled there will be some movement due to the effect of water pressure on the walls and the overall weight of water in the pool. After filling, the water will be brought up to normal pool temperature and this will cause some further movements in the overall structure.

The affect of pool water chemistry on the grout Chemicals added to the pool water tend to degrade cement-based grouts. This is minimised if the pH balance is maintained at the ideal levels but the choice of grout and its chemical resistance are important factors for the durability of the installation.

Certain areas are exposed to additional wear and tear Certain parts of the pool are exposed to more aggressive conditions than others. The grout on the pool sides at the waterline may be exposed to greater erosion from water movement. Pool surrounds may undergo stringent and frequent cleaning regimes. Walls in rooms containing pools will be exposed to constantly high humidity and also need to have good water resistance.

56 52 53 08 22 20 11

There are several solutions depending on the level of durability required and these are outlined as a hierarchy below. Of course there are intermediate levels, for example using Acid-resistant Grout.

Preparation The pool shell must be allowed to cure for at least 6 weeks before rendering/screeding and then at least another 3 weeks must be allowed before commencing tiling. The pool shell must be watertight in its own right by priming with Plaskey and Key‑it. Ensure that the surface is sound, clean, dry and free from dust, laitance etc. Standard solution Fix the tiles with Ceramic S or Ceramic L mixed with Bond‑it. Allow the adhesive to cure for at least 3 days, then grout with Tile Grout mixed only with Bond‑it. Improved-resistance solution Fix the tiles with Porcelain Rapid 12 mixed only with Bond‑it. Allow the adhesive to cure for at least 3 days, then grout with Acid-resistant Grout. Fix the tiles with Quick Set 6 mixed with Bond‑it. Allow the adhesive to cure for at least 3 days, then grout with Acid-resistant Grout mixed with Bond‑it. When fixing sheets of mosaic tiles, it is also possible to fix and grout simultaneously. Putting the pool into service Allow at least 3 weeks after finishing grouting before filling the pool. Fill the pool at a rate of no more than 0.75 m of depth per day, to allow any movement to take place slowly. Bring the pool gradually up to temperature, at a rate of 0.25°C per hour.

Exterior Tiling

Tile Adhesives Quick Set 6 Bond-it Tile Grout Quarry Tile Grout

Exterior tiling is exposed to more aggressive conditions than interior tiling. The effects of sun, wind, rain, and frost combine to shorten the life of an installation, by exposing it to a continuous onslaught of a number of mechanisms.

Water expands on freezing So in a confined space, generates enormous forces. In cold climates the cumulative effect of repetitive cycles of freeze (expand)/thaw (contract) causes rocks to fracture. This action, known as frost shattering is part of the mechanism for weathering. For tiling this has several implications: • Pores in the grout will be vulnerable to frost damage. • Any voids behind the tile provide a possibility for water to gather and then on freezing, push off the tile.

Exterior situations undergo large changes in temperature Interior tiling situations tend to be more or less constant temperatures. Exterior installations, however, are exposed to much larger cyclic temperature swings. With changes in temperature, different materials expand and contract at different rates. When they are fixed rigidly together this causes stresses to build at the interface between the materials. If the stress gets high delamination occurs.

04 11 53 22 21

Standard cement-based tile adhesives are suitable for exterior use, highly polymer-modified adhesives offer enhanced bond-strength, reduced porosity and therefore better resistance to frost and greater resistance to movement (thermally induced movement is inevitable particularly for walls). Tiles recommended for exterior use will often be fully vitrified and these also require a higher specification for the adhesive.

Fixing the tiles We recommend Quick Set 6 which is highly polymermodified. Alternatively, it can be modified by the addition of Bond‑it admixtures. It is very important that a solid bed of adhesive is achieved behind the tiles to prevent water collecting and this is easiest to achieve by back buttering the tiles in addition to spreading adhesive on the wall. It is good practice to occasionally remove a tile during fixing to ensure that the appropriate contact is being achieved. If tiles are large, heavy or being fixed above first-floor height (3 m), they must also be mechanically fixed. Construction requirements Any movement joints in the building structure must be carried through the tiling layer and intermediate flexible joints included at suitable intervals. Grouting As with adhesives, highly polymer-modified grouts are more durable due to their reduced porosity, higher strength and resistance to flexing. Tile Grout or Quarry Tile Grout with addition of Bond‑it can be modified by the addition of admixtures. Ensure that the joints are completely filled with grout and tool the surface to obtain a closed surface texture. Protect the top edge of the highest row of tiles from water ingress.

• • • •

Provides increased water repellency Assists in providing even absorption Reduces water absorption Reduces risk of surface crazing of poured concrete and precast concrete • Reduces surface water absorption • Provides economical and durable renderings and mortars • Reduce staining of cement plaster, in situ concrete and precast concrete

Mixing • Mix 1 kg of Barrier Cement Waterproofing Additive to a 50 kg Bag of cement. • Mix the powder with the cement in a dry state, then add the aggregate and water. • Mix thoroughly but air entrapment and machine mixing of concrete is unduly prolonged once water is added. • Use only clean, sharp, well graded aggregates for concrete. Storage & Shelf Life • Store in dry conditions. Shelf-Life of unopened bag is at least 12 months.

Please Note In all cases the strength of the mix should be in accordance with the specification and SABS / ISO standards applicable to the particular work to be carried out. As a guide, however, concrete should contain not less than 300 kg of cement per cubic meter (although a richer mix is often necessary). The addition Barrier Cement Waterproofing Additive will not compensate for incorrectly proportioned mixes or for poorly compacted concrete. Mixes containing Barrier Cement Waterproofing Additive are water repellent. For floors it is recommended that a vapour membrane be provided.

2 — Slurry Coat • Prepare a slush coat consisting of Marbelite in a solution of 1 volume Marbelite and 4 volumes water. Mix well. • Apply to the surface using a block brush. The surface should have a stippled finish. • Allow slurry coat to harden for 12 hours (but no longer than 24 hours). • If mixing is done on the floor of the pool, care should be taken not to remove the slurry coat. • Do not wet the slurry coat before Marbelite application commences. 3 — Plastering • Using a rounded steel trowel, apply the first layer of Marbelite to the walls by forcing the material tightly against the surface. • Follow immediately with a second layer to an application not exceeding 8 mm. • Start plastering the floor from the deep end. • When the Marbelite is green (set but not fully hardened) it should be given a final trowelling to polish the surface and remove trowel marks. • Wet the surface slightly to avoid black burn marks. • All plastering must be completed in one day to avoid unsightly joint marks. • Leave overnight to air cure.

Application: Plastering a New Pool • The surface must be damped down before plastering commences. Be sure to remove any standing water from the floor. • Apply the first layer of Marbelite to the walls by forcing the material tightly against the surface using a rounded steel trowel. • Follow immediately with a second layer to an application not exceeding 8 mm. • Start plastering the floor from the deep end. • When the Marbelite is green (set but not fully hardened) it should be given a final trowelling to polish the surface and remove trowel marks. Wet the surface slightly to avoid black burn marks. • All plastering must be completed in one day to avoid unsightly joint marks. • Leave overnight to air cure. Filling & Curing for New & Re-plastering • Start filling the pool from the deep end. Attach a deflector to the end of the hosepipe to prevent surface damage. Damp down exposed Marbelite every hour to prevent it drying out prematurely. Fill the pool in one operation to prevent a water-ring from forming. • Do not introduce an automatic pool cleaner to the pool for 3 weeks. Use the pool brush only to remove dust and debris (vacuum to waste daily). Brush the marbelite surface using a soft pool brush and back-wash at least once a day.

Note It is critical that the correct volume of water is added. Too much water will influence the final strength of the Marbelite. The first four weeks in the life of a newly plastered pool is the most critical time. Please read the guide to the chemical treatment of newly plastered pools carefully. Safety Instructions Contains cement, which is alkaline when wet and can cause skin irritation. Use eye protection and gloves and avoid prolonged skin contact. Avoid inhalation of dust. Wash skin contamination away with warm soapy water. Remove splashes to the eyes by prolonged irrigation and consult a doctor. Do not ingest.

How-to chemically treat newly plastered pools

Important information • It is important that the chemical manufacturer’s dosing instructions be followed when adding chemicals to the pool. • The Marbelite surface can be damaged by overdosing. • Acid overdosing destroys total alkalinity which leads to etching of the Marbelite surface. • Always dilute acid before dosing, and add while the pump is running to ensure even distribution. • Calcium hypochlorite (dry granular chlorine) overdosing causes scale build-up and high pH. Trichloroisocyanuric acid (stabilised chlorine) overdosing causes calcium to be leeched from the Marbelite surface and leads to etching of the surface. • Do not allow chlorine pills- or granules to come into contact with the surface of the Marbelite.

The water in a pool is a balanced unit. Correct water treatment will ensure that your pool is an asset and not a liability. Marbelite is formulated to the highest standards and if properly maintained, can be expected to last in excess of 20 years. The first four weeks in the life of a newly plastered pool is the most critical time. Proper care during this time will ensure that the Marbelite will cure as it should and provide years of trouble-free service. Tap water varies from area to area and it is important to ascertain the balance of the water by taking it to a pool shop for testing. The results of this testing will guide you as to what should be added to the water to ensure proper curing of the Marbelite.

Main Considerations The pH must remain at 7,8. Do not use any hydrochloric acid during the first 3 weeks. Dose only with small quantities of unstabilised granular dry chlorine, or unstabilised liquid chlorine during the first 3 weeks. The presence of iron or copper in the water. A high metal content will cause staining of the Marbelite surface. Calcium hardness. The ideal is 300 to 400 ppm. If the calcium content is too low, calcium will be leeched from the Marbelite, making the surface rough. It is important to have the water tested before filling the pool.

At the start of week 4 • Check the pH and add hydrochloric acid (quantity to be determined based on the volume of the pool) dissolved in a plastic bucket of water from the pool with the filter running. • Periodically dose until the pH is between 7,4 and 7,6. It could take several days to correct the pH. • Never use sulphuric acid in the pool. • Follow the chlorine manufacturer’s dosing instructions from now on. • If a salt water chlorinator is installed refer to the manufacturer’s instructions. • Connect the automatic pool cleaner.

The pool shop will recommend the appropriate products to remedy the quality of the water. Chemicals should only be added once the pool is filled completely. •

White marks on coloured Marbelite Usually a build-up of calcium on the surface of the plaster caused by high pH levels. Calcium is white giving the perception that the colour id fading. Fix as follows: Drop the pH level to 7 by adding hydrochloric acid. Brush the surface daily and back-wash. The low pH will soften the calcium and the brushing will loosen it. Severe build up can take some time to remove. The pH should not be kept at this level for more than 7 days at a time. Day 8 - raise the pH to 7,2. If, after 7 days, there is still evidence of white marks, repeat the process. Unless correct water treatment is maintained, calcium build-up will re-occur. In extreme cases the pool might have to be emptied and sanded. Contact our Technical Department for information. Brown marks on white Marbelite This is caused by calcium build-up that traps dust when it calcifies. It will normally occur on the floor of the pool and can be rectified by following the steps described above.

Pool Paint

• • • •

Durable, coloured, waterproof finish for revamping of marble plastered pools. Not suitable for use on newly plastered, fibre-glass or previously painted pools

• • • • • • • •

Suitable Surface • Marble plastered swimming pools. • Not suitable for use on newly plastered, fibre-glass or previously painted pools.

Waterproof Integrally coloured Very simple to apply Available in a range of colours Quality assured raw materials Exceptional and consistent quality Backed by superior technical support Cement-based

Consideration Incorrect water treatment causes the surface of marble plastered pools to become rough and stained over time. The usual way of solving this is to re-plaster the pool, which is quite a costly exercise. Pool Paint is designed to provide a cost effective solution to this problem. It will colour and revitalise the surface, thereby postponing the need for re-plastering. It will not cover defects or structural cracks. With proper water treatment and correct maintenance of the automatic pool cleaner, this coating can be expected to last for at least 4 years. It must, however, be noted that the pool will have to be replastered eventually. Storage & Shelf Life When stored, unopened in a dry place at temperatures above 5oC, shelf life is 12 months from date of manufacture.

Good Practice Do not apply if frost is forecast within 24 hours of use Do not apply in damp or wet conditions Do not apply in temperatures below 5oC or above 30oC To ensure colour consistency, the material required to complete the job should be of the same batch number.

Available Colours White | Light Blue | Slate

Surface Preperation • Prepare a solution of 1 part of hydrochloric acid and 3 parts of water in a plastic bucket. Put the water in the bucket first and then add the acid while stirring. Be sure to wear gloves and eye protection. • Apply the acid mix to the surface using a blockbrush. • Scrub the surface vigorously using a wire brush and flush with clean water. Leave to dry for at least 3 hours. • Remove high spots and calcium build-up using 80 grit sandpaper. Be sure to remove any loose materials. • The surface should be very rough to touch. If this is not the case, repeat the acid washing procedure described above. • Brush and vacuum the entire surface to remove dust and debris. Dust on the surface will impede the adherence of the Pool Paint. Mask all areas where there is a risk of splashing and staining and where straight edges are required. Mixing • The use of a mixing spindle attached to an electric drill is recommended to ensure proper mixing. • Pour the liquid into the drum. • Slowly add the powder from the plastic bag while stirring. The mixture should be smooth with no lumps. A small amount of water may be added if required. • Once the contents are mixed, ensure that the product is used immediately. Masking Mask all areas where there is a risk of splashing and staining and where straight edges are required. Masking tape must be removed before the material has dried.

Note Apply a 1 mm coloured layer, in much the same way as paint, on a plastered wall. Because it is cementbased, the coating becomes part of the marble plaster surface through the hydration process of cement. It is not merely a surface film and will therefore be very durable. Calculating the Surface Area Calculation for an average 4 x 5 m pool: • Length = 5 m • Width = 4 m • Average depth = 1.3 m Therefore: • Floor 4 x 5 m = 20 m² • Width 4 x 1.3 m x 2 sides = 10 m² • Length 5 x 1.3 m x 2 sides = 13 m² Total = 43.4 m² (= 2 x 20 L buckets of Pool Paint) Coverage Coverage is approximately 20—25 m2 per 15 kg pack (applied in 2 coats).

Floors & Screeds General Information All Weber screeds are designed to cope with high levels of traffic (foot and forklift), and provide excellent resistance to wear, abrasion and point loads. Specifying a weber.floor screed or floor floating product enables the contractor to speedily complete the necessary work (often much faster than traditional methods), which in turn allows for foot and forklift traffic within a short period of time. This minimizes downtime and ensures the installation is cost effective. Weber’s range of screeds consists of both standard- and high-strength base/ top screeds, all of which are hard-wearing, and can be applied as the final finish (overlay) or receive further sealing coats/floor-coverings.

The existing substrate needs to be of sufficient quality, hence the existing substrate needs to exhibit a minimum pull-off strength of 0,1 n/mm2. Screeds with high compressive strengths are prone to cracking if they do not have an adequate level of flexural strength. The higher the the flexural strength of a screed the less likely it is to crack. All Weber Floor Solutions are designed to provide a ‘best in class’ combination of compressive and flexural strength.

Weber Floor Solutions can be used to reduce the cost of the building’s structure as they can be applied much thinner than traditional screeding materials.

Weber will, at all stages, be involved in the flooring project to ensure that the customer’s expectations are met. Weber Floor Solutions are hence only distributed and installed through approved/accredited contractors, who together with Weber will provide the customer with a material and workmanship guarantee respectively. Weber Floor Solutions are also produced in a manner compatible with low CO² emissions, low dust and significantly lower pH levels.

The systems are for use as external insulation on commercial and residential buildings, which are designed in accordance with the general building regulations.

Technical Investigations & Design Considerations The system should be designed to withstand the wind pressures (including suction) and thermal stresses in accordance with existing building regulations.

12 8

The system must have adequate resistance to severe mechanical or malicious impact and abrasion where walls are exposed, and be provided with some form of protection. The design should take into account damage resulting from impact by motor vehicles or other machinery. Preventative measures such as the provision of protective barriers, or kerbs, need to be considered.

The Certificate Holder operates a quality management system (ISO 9001 & 14001) and a quality plan is in place for system manufacture, design and installation.

Installation To be carried out by Weber recommended contractors, and shall be in accordance with the Project Pack as well as the requirements outlined in the specifications.

The system is designed by Weber in conjunction with Specifiers on a project specific basis. The installation of the system is carried out by installers who have been trained and accredited by Weber. Weber offers a ten-year materials guarantee, subject to certain terms and conditions. The Contractor offers a workmanship guarantee in accordance with the NHBRC. All system components shall be supplied by Weber unless specifically otherwise agreed.

Aesthetic Performance As with traditional renders, the aesthetic performance of the system, e.g. due to dis-coloration, soiling, staining, algae growth or lime bloom is dependent on a range of factors such as: • The type, colour and texture of surface finish • Water retaining properties of the finish • Architectural form and detailing • Building orientation/elevation • Local climate/exposure conditions atmospheric pollution
