SuperSeal® was developed as an economical, fast-drying sealing agent for a variety of porous surfaces including gypsum plasters, concrete and wood. This sealing agent will quickly and effectively seal surfaces without interfering with surface detail. Mold rubber (polyurethane, silicone or polysulfide) can then be applied. SuperSeal® offers Low Cost, Low Viscosity – wets out well over any surface. It evaporates quickly and its ultra thin film gives cured rubber mold surfaces a smooth, satin finish. SuperSeal® is also removable and can be rinsed from model surface with warm water.
