Description Rustins Acrylic Wood Filler is a fast drying, ready to use flexible filler that is easy to sand, stain and paint. Using a suitable filling knife, work the filler into the wood, allowing up to 2 hours to dry between layers. Once dry, the filler can be painted, stained or varnished. Try a small inconspicuous area first as the filler may stain on the area filled.
