About this product
This 30g hardener sachet is the catalyst used with Ronseal High Performance Wood Filler, activating a two-part system for chemically bonded, permanent wood repairs. Once mixed, the filler won't shrink or crack, and can be filled to any depth, then drilled, screwed or planed once cured.
It's suited to interior or exterior repairs deeper than 5mm, such as window frames, sills, doors and door frames. The catalysed filler dries in around 30 minutes and offers a very high level of protection. Application is by filling knife, with the filler itself available in Natural, Dark or White. For shallower surface repairs, Ronseal Multi Purpose Wood Filler is recommended instead.
