FASTASEAL 3528 is a clear single pack, fast drying sealer which is easily sanded and has excellent adhesion to all timber species. Formulated to be applied as a thin first coat under all Polycure coatings, FASTASEAL 3528 provides an excellent block to resin exudation problems in oily timbers such as Brushbox, Tallowwood & Spotted Gum. It is an efficient isolator to wax extraction problems experienced with particle board and minimises the darkening of timber usually associated with solvent based coatings.
