Polycell Polyfilla for Wood is a ready to use, low odour, multi purpose wood filler for general and minor repairs to interior and exterior wood. The formulation is quick drying, giving a tough and durable fill that flexes with the natural movement of wood. Can be painted, stained or varnished in 2 hours (depending on conditions) and fills holes up to 10mm deep in one application. The filler will not shrink or crack, and can be nailed or screwed. It is water resistant, and can be used for interior and exterior use.
