Detersil is an emulsifying detergent for silicones. To obtain maximum adhesion of paint to GRP surfaces without having to sand the surface thoroughly, it is necessary to first remove any mouldrelease agents. Since these agents contain wax, paraffin or silicone, a specialy detergent product must be used. Detersil has a dissolving and emulsifying action and can be used whenever a surface has to be cleaned thoroughly before painting.
