1.2
CONCRETE SUBSTRATE PREPARATION All substrates must be structurally sound, dry, solid and stable. Any laitance, dust, grease, oil, paint or curing compounds present on the surface of the concrete substrate that may inhibit bond, shall be mechanically removed. The substrate should then be cleaned and prepared in accordance with the relevant standards and as per the MAPEI technical data sheets (TDS).
1.3
MOISTURE VAPOUR BARRIER • NOTE: Prior to the application of the moisture vapour barrier (MVB), relative humidity (RH) readings must be carried out in accordance with ASTM F2170. Moisture vapour barrier to be chosen from the following options: A.
PRIMER MF (544-02-2018 AUS) Epoxy moisture barrier for cementitious substrates.
B.
MAPEPROOF 1K TURBO (2918-02-2018 AUS) <95% RH, 28 day old concrete One component, solvent free, moisture curing and rapid drying polyurethane surface membrane with a very low emission of volatile organic compounds. • APPLICATION:
Apply with a roller, brush or flat trowel,
A single coat is usually sufficient, providing a continuous layer with a glossy film on the surface is achieved. For more porous substrates, or substrates in poor condition, a second coat should be applied.
• NOTE: Where the subsequent application of levelling compound is to exceed 10 mm, or if the area is expected to receive high stresses, apply at least 2 coats and completely saturate the final fresh coat of the moisture vapour barrier with QUARTZ 0.9 AU. Once the moisture vapour barrier is dry and fully cured, all excess sand is to be removed via vacuum cleaning and the area is to be inspected for any bald spots (where the moisture vapour barrier has no sand). All bald spots must receive an additional coat of moisture vapour barrier, saturated with QUARTZ 0.9 AU as detailed above. 1.4
PRIMER – IF LEVELLING COMPOUND IS TO BE USED • NOTE: ECO PRIM T PLUS may be applied to the MVB once it dry to touch (Approx. 2 hours for MAPEPROOF 1K TURBO, 4 hours for PRIMER MF) but no longer than 24 hours. Primer not required if moisture vapour barrier was broadcasted with sand. A.
ECO PRIM T PLUS (2930-04-2018 AUS) Solvent free acrylic primer in water dispersion with very low emissions of volatile organic compounds. • APPLICATION:
Primer applied using a brush or roller undiluted over the MVB in accordance with the TDS. Ensure no puddling of the primer occurs.

MAPEI: T01 Version: 25/06/2020 Revision: 4
LEVELLING COMPOUND – IF REQUIRED • NOTE: Levelling compound can be applied 2 to 3 hours after applying the primer, but no longer than 24 hours. Levelling compound to be chosen from the following options: A.
ULTRAPLAN ECO (513-05-2017 AUS) Ultra-fast hardening self-levelling compound with very low volatile organic compounds. Applied in thicknesses from 1 to 10 mm per application.
B.
ULTRAPLAN (501-05-2017 AUS) Ultra-fast drying, self-levelling compound with very low volatile organic compounds. Applied in thicknesses from 3 to 15 mm per application.

D.
ULTRAPLAN TRADE (4079-2-2020 AUS) Fast drying, interior levelling and smoothing compound from 3 to 40 mm per pour.
E.
ULTRAPLAN FAST TRACK (4027-05-2017 AUS) Ultra-fast drying self-levelling compound for thicknesses from 1 to 10 mm. • APPLICATION:
1.6
Spread the levelling compound in thicknesses according to the product used, using a large metal trowel or float, tilting the trowel slightly to obtain the desired thickness.
ADHESIVE • NOTE: If applying directly to the moisture vapour barrier, use ULTRABOND ECO S955 1K. Adhesive to be chosen from the following options: A.
ULTRABOND ECO S955 1K (270-2-2016 GB) One component, solvent free, sililated polymer-based adhesive with a very low emission level of volatile organic compounds for all types of parquet.

SUBSTRATE PREPARATION Difficult substrates include: •
Ceramic and stone tiles
•
Terrazzo
•
Existing solid timber and T&G flooring
•
Structural plywood
•
Structural particle board
•
CFC sheeting
All substrates must be structurally sound, dry, solid, stable and well bonded. Any dust, grease, oil, paint, curing compounds, or other contaminants present on the surface of the concrete substrate that may inhibit bond, shall be mechanically removed. Wood-based substrates must have all wax and sealers removed by sanding. The substrate should then be cleaned and prepared in accordance with the relevant standards, substrate manufacturers guidelines, and as per the MAPEI technical data sheets (TDS). 1.3
PRIMER A.
ECO PRIM GRIP (2916-2-2018 GB) Multi-purpose, ready-to-use bonding promoter primer made from synthetic acrylic resin and silica inerts with a very low emission of volatile organic compounds (VOC) for render, smoothing and levelling compounds and adhesives for ceramic tiles. • APPLICATION:
1.4
Stir ready-to-use primer prior to application, no dilution is required.
Apply primer with either a roller or brush.
LEVELLING COMPOUND A.
ULTRAPLAN RENOVATION (4013-05-2019 AUS) Fibre reinforced levelling compound for interiors applied from 3 to 40 mm in a single application. • APPLICATION:
Pour 3.4 to 3.6 litres of potable water into a clean container then add the 20 kg bag of ULTRAPLAN RENOVATION while using an electric mixer. Once a lump-free mix is obtained, let it stand for 2 to 3 minutes then briefly remix.
Spread levelling compound from 3 to 40 mm in thickness using a large metal spreader at a slight angle to obtain the desired thickness.
It is recommended to introduce saw cuts once the levelling compound can be walked on for large areas at high thickness to alleviate stress.
Allow 1-3 days of curing (depending on leveller thickness) prior to bonding the timber flooring.
