Osmosis

Osmosis What is Osmosis? There is a continuous demand for production of boats based on glass fibre reinforced polyester resins, a material that offers big advantages. When G.R.P. yachts were first produced it was believed that they would be devoid of all forms of decay. This has since been proved wrong with the occurrence of degradation by osmosis. When two liquids of different concentrations are separated by a semi-permeable membrane then liquid will migrate in an effort to equalise the difference in concentration. During this process the volume of the most concentrated solution will increase and a pressure build up can develop. The membrane is the gel coat of a G.R.P. yacht and the liquid is water. Given time the G.R.P. will absorb water and this will permeate through the hull into the bilges with little damage. However, a certain amount of the moisture will breakdown some of the materials used in the laminate itself and this will lead to a build up of fluids containing acetic acid and glycol, known as osmotic fluids. Water will migrate into any voids in an effort to dilute the concentration of the osmotic fluids. The osmotic fluid has a higher molecular weight than water and is therefore unable to leech out. As more moisture is absorbed a liquid pressure builds up and this leads to blisters within the gel coat. The hulls of most G.R.P. boats could at some stage during their life develop some form of osmosis. This occurrence can depend upon various factors including temperature, type of water and how often the hull is allowed to dry out and most importantly, the quality of the original laminate. A blister caused by osmosis will contain acetic (vinegar) smelling liquid. It is possible to discover problems within the hull before the blisters appear if the hull is examined with a moisture meter.

Osmosis process in GRP boats

The water come in through the existing microspheres in the Gel Coat. It concentrates itself in the poor resin areas, in the air bubbles blocked on the laminate or between Gel Coat and laminate. The hydrosoluble chemical substances are accumulated on these areas which have formed water concentrated solutions. Hydraulic pressure encourages the blisters growth destroying the different coats of the laminate until the Gel Coat brakes to the eliminate pressure.

Inspection It is suggested that all yachts made of polyester fibreglass material be rigorously inspected prior to annual maintenance and application of antifoulings. The existing layer of antifouling could mask small mechanical damage and cracking. It is therefore advisable that all antifouling is removed periodically to expose the gel coat and an inspection carried out prior to the reapplication of the antifouling system. Osmosis is the biggest problem that can befall a boat made from G.R.P. It manifests itself first in small blisters or craters that can be concentrated in one area or spread out over the whole surface of the hole. A vessel made of G.R.P. can develop osmosis over a long period during which time an irreversible chemical reaction takes place. The problem only becomes apparent when blisters appear on the surface of the hull. When the blisters are opened there will be a strong smell of vinegar (acetic acid).

To trace the origin of the blisters a litmus paper should be used, wetting the paper with the fluid from he blisters. Values of pH in the range 4 - 5 denotes the presence of acetic acid, values of pH between 10 - 12 indicate the presence of the remains of accelerating agent used in the laminating process of the G.R.P. If the hull is not showing any symptoms of osmosis but you want to check the humidity of the laminated layers this can be done with a Skipper Humidity Meter (or similar). With the selector in Scale 2 readings below 65 show the hull is in good condition. Before taking any humidity readings you must make sure that the water tanks and the bilges are completely dry. Measurements can be distorted where metal or wood reinforcements are present.

Repair Gel Coat Removal Once the state of the hull has been evaluated the gel coat should be removed with a GelPlane, starting at the waterline (refer to GelPlane Handbook for details). The thickness and hardness of the gel coat will determine the cutting depht but ideally all gel coat should be removed to expose the glass fibre bellow. Once this process if complete then it is necessary to clean the area thoroughly using a jet wash with hot water and silica sand. This process will remove the areas of fibre where there is a lack of resin and will also prepare the area for subsequent repair material.

Drying Once the gel coat is removed it is important that the hull is washed repeatedly with fresh, preferably hot, water at regular intervals. The washing removes the acid and draws out the contamination which accumulates during the drying process. Measuring the humidity of the laminate in all zones prior to washing and during the drying process is essential. Some readings all over the hull must be taken with a suitable equipment, such us Skipper Moisture meter. Set the equipment at the Scale 2 and take readings on both sides, from waterline to the keel. Note:

Before taking readings, remember to empty bilges and tanks (humidity inside will also be measured!) and the interior of the boat should be well ventilated. The drying process will take at least 40 days, depending upon the RH, temperature, etc. When readings below 40 on Skipper Scale 2 are reached then the osmotic curing system designed by Jotun can be applied.

Osmosis Treatment Job procedure Since the Gelcoat has been removed, it is necessary to re-build a proper protection coat on the fibre glass. For that, a solvent free, glass flake reinforced epoxy coating is used, in order to obtain a true waterproof barrier, by applying the following system: Apply the first coat of OSMOSHELL with a flat spatula. This must be worked in all directions to ensure that all cavities are filled with material and to rebuild the previously cleaned damaged areas. Within 24 hours apply the first layer of OSMOSHELL, using a flat spatula to apply the product and a teeth spatula (teeth of 2-3 mm.) to ensure the film thickness. Work vertically from the bottom of the hull towards the top. After 12 hours and no late than 24 hours the next coat of OSMOSHELL should be applied, using a flat spatula and filling all valleys left by the teeth spatula application technique. Between 12 and 24 hours later, remove all sharp areas of OSMOSHELL and apply one coat of FINISHING FILLER to even the whole surface. This product can be sanded to a get a smooth finish after 12-16 hours. After sanding, apply one coat of 100 microns dry film thickness of ANTIPEST and allow at least 8 hours to dry. After proper drying as per technical data sheet, apply by roller one coat of 50 microns dry film thickness of NONSTOP and allow 12 hours to dry. Apply one further coat of 50 microns dry film thickness of NONSTOP and allow to dry. Application can be done by airless spray applying one single coat of 100 microns dry film thickness.

Job procedure It is very important to follow below procedure to assure a proper application result: 01. First coat First step Osmoshell: Skim coat applied to fill in holes, pores and imperfections.

02. First coat Second step Osmoshell: Applied by tooth spatula of 2 mm. to secure 1 mm. height of the peaks.

03. First coat Third step Osmoshell: Applied by smooth spatula to fill in valleys left with first application so an even coat of 1 mm. d.f.t. is obtained.

04. SECOND coat Finishing Filler: Applied by smooth spatula to even the roughly surface left by Osmoshell application.

05. SECOND coat Finishing Filler: After the Finishing Filler has cured it can be sanded to a smooth finish prior to painting.

06. THIRD coat AntiPest: After the Finishing Filler has been sanded, AntiPest is to be applied, either by airless or brush/ roller.

06. FOURTH COAT NonStop: After the application of the AntiPest, antifouling can be applied, either by airless or brush/ roller.

Job procedure - repair of supports

Smooth the edges of the surface using a chisel, once the products are completely cured and clean the area with solvent or BoatWash, prior to sanding, and remove all dust afterwards.

Carefully mask the area to be painted using a masking tape. Avoid any application of Osmoshell on top of the newly applied Antifouling.

Apply the complete osmosis treatment, primers and antifouling.

Surface preparation Coated surfaces Prior to paint application, all surfaces should be clean, dry and free from contamination. Remove surface contamination by high pressure fresh water cleaning. To be applied on a clean, dry approved primer/undercoat. Other surfaces The coating may be used on other substrates. Please contact your local Jotun office for more information.

Condition during application The temperature of the substrate should be minimum 3ºC above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Good ventilation is usually required in confined areas to ensure correct drying.

Application methods Spray Brush Roller Recommended.

Use airless spray or conventional spray May be used but care must be taken to achieve the specified dry film thickness. However when using roller application care must be taken to apply sufficient material in order to achieve the specified dry film thickness.

Single pack Jotun Thinner No. 7 15 MPa (150 kp/cm², 2100 psi). 0.53-0.78 mm (0.021-0.031”) 65-80° Check to ensure that filters are clean. 3.5 - 4.5 bar (kg/cm²) 1.6 - 1.8 mm Check to ensure that water and oil filters are available. Distance from air compressor to filters is to be min. 10 m. Spray application must only be done by a professional.

Drying time Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with: * Good ventilation (Outdoor exposure or free circulation of air) * Typical film thickness * One coat on top of inert substrate Substrate temperature Surface dry Through dry Dry for launching (1) Dry to recoat, minimum (2)

5°C 8h 24 h 30 h 16 h

10°C 5h 16 h 24 h 12 h

23°C 3h 12 h 12 h 8h

40°C 2h 4h 8h 4h

(1) The drying time will increase with increasing film thickness. (2) The surface should be dry and free from any contamination prior to application of the subsequent coat.

Typical paint system Suitable primer system with AntiPest or Vinyl Primer as a sealer coat. NonStop

2 x 50 μm (Dry Film Thickness)

Other systems may be specified, depending on area of use.

Instruction of use Gelcoat hulls: Degrease with suitable cleaner. Wet sand the surface with wet sandpaper No. 180-220. Rinse well with freshwater and allow to dry. Apply 250 μm Dry Film Thickness or 4 coats of AntiPest and finish with two coats of NonStop. Wooden hulls: Apply 5 to 15 coats of Clipper I, depending on absorption of the substrate. Apply “wet- on-wet” do not let the previous coat dry before applying the next. Wipe of any excess product. Apply 2-3 coats of Vinyl Primer and finish with two coats of NonStop. Steel hulls: Blast cleaning or grind back to bare metal. Apply 2 coats of Epoxy Yacht HB, 1 coat of AntiPest (if Epoxy Yacht HB is not available, apply 3 coats of AntiPest). Finish with two coats of NonStop. Ferrocement hulls: Acid wash, then rinse well with freshwater. Allow to dry. Apply 1 coat of Penguard Clear Sealer and 3 coats of AntiPest. Finish with two coats of NonStop. Aluminium hulls: Degrease with suitable degreaser and rinse well with freshwater. Grind and dedust the surface. Apply 2-3 coats of AntiPest and finish with two coats of NonStop White or Grey. Other colours of NonStop must not be used on aluminium hulls. Previously coated surfaces: NonStop can be applied directly on selfpolishing antifoulings in good conditions. Hard antifoulings in good condition should be lightly wet sanded before application of NonStop. If the existing antifouling is a soft or unknown antifouling, it is advisable to apply one preventive coat of Vinyl Primer. If the old antifouling is in bad condition, scrape and sand-down any areas of flaking or cracked antifouling. Wet sand the surface with wet sandpaper No. 180-220. Rinse well with freshwater and allow to dry. Apply 1 coat of Vinyl Primer and 2 coats of NonStop. For application on aluminium hulls, NonStop white or grey are the only recommended colour.
