Ronseal High Performance Wood Filler is for repairing all woods both interior and exterior.
It is a 2-part formula that can be used to fill any depth and dries solid in 30 minutes. Once dry it can be sanded, planed, filed, screwed or nailed. It can be painted, stained or varnished.
Application is made using a suitable filling knife or blade.
For areas of rotten wood, remove as much decayed wood as possible until you're back to a solid surface and treat with Ronseal Wet Rot Wood Hardener before finishing with High Performance Wood Filler.
