Everbuild All Purpose Powder Filler White 450g. This is a high strength powder filler ideal for most indoor and outdoor repairs to plaster, plasterboard, brick, render, wood, and stone. When mixed with water, the filler is ready to apply in one minute and dries in about one hour to a smooth sandable finish. Due to the high levels of added PVA powder, this filler will not shrink or crack and is strong enough to accept nails and screws. It is overpaintable with most solvent-based and emulsion paints, and overstainable. For exterior use, always overpaint with an oil-based primer and top coat to protect the filler.
