Instructions forBonding Anti-Slip Deck CoveringsDescription of ApplicationDeck coverings or mats ofsynthetic resin compositionprovide a safe, non-slip surface towalk on as well as protecting thedeck against damage and leaks.The use of a one-part polyurethaneadhesive maximises theeffectiveness of the coveringmaterial, facilitates installation andensures a professional finish.Proprietary deck coverings incommon use include:T B SAnti-slideTreadmaster Lay TechPolygripNautoflexNoramentMarine Deck 2000One-part polyurethane adhesivesgive excellent results with theseproducts. Installation is simple andstraightforward, while the longterm performance characteristics ofthe adhesive offer a number ofsignificant benefits.Timber DecksAbrade contact area on hull withsanding pad (80/100 grit) and removedust with a vacuum cleaner.290 DCApply a thin, continuous coat of Sika ®Primer-290 DC, using a clean brush orfelt applicatorDrying time: minimum 60 minutes,maximum 24 hoursAluminium Decks,Coated with Two-Part LacquerClean the substrate with Sika ®Cleaner-205, using a clean, lint-free205rag or paper towel. Changefrequently!Drying time: minimum 10 minutes,maximum 2 hoursFor the preparation of othersubstrates, please refer to thePrimer Chart.Deck CoveringsThe covering material must be freefrom release agents or other mediaused in the production process. UseMEK, Colma Cleaner, or otherappropriate solvents recommendedby the manufacturer. Perform a smalltest to verify if the substrate isaffected by the solvent.On non-porous coverings, the side205that is to be bonded should becleaned with Sika ® Cleaner-205, usinga clean, lint-free rag or paper towel.Change rag frequently!Drying time: minimum 10 minutes,maximum 2 hoursIn the case of covering materials withan open-pore structure or texturedweave finish, the only preparationnecessary is to ensure that the side tobe adhered to is completely dust-free.Note: Due to the many variationsof deck coverings, a test to check foradhesion is always recommended.Preparation of Substrateand Deck CoveringsGRP DecksHeavily soiled surfaces should becleaned off first with a pure solvent(Sika ® Remover-208) to remove theworst of the soiling.Lightly abrade contact area with a veryfine sanding pad (Scotch Brite M 600).Remove dust with a vacuum cleaner.Clean the substrate with Sika ®205 Cleaner-205, using a clean, lint-freerag or paper towel. Change frequently!Drying time: minimum 10 minutes,maximum 2 hoursApplication of Sikaflex®-291/-298 Adhesive208Flat surfaces: Sikaflex ® -298. Inclined surfaces: Sikaflex ® -291Apply adhesive to previously prepared surface and spread over area to be covered, usinga spreader with 2 mm triangular notches. The layer thickness should be 0.5–1 mm approx.The covering material must be placed in position within 30 minutes of applying theadhesive, so adhesive should be applied only to an area large enough to receive the nextsection of covering.When the covering has been placed in position it should be rolled down with a rubberroller, working from the centre outwards to expel any trapped air and push any excessadhesive out to the edges, where it can be removed. It is essential to ensure no trappedair remains.Note: If the covering material is laid under tension, the edges must be held or suitablyweighted.Traces of uncured Sika adhesives or sealants may be removed with Sika ® Remover-208.On no account should other cleaning agents or Sika ® Cleaner-205 be used for this purpose.Important: Please refer to the current Sika Technical Data Sheets and Safety Data Sheets obtainable throughSika or their local distributor.9
