Ronseal High-Performance Wood Filler, Dark, 275g
Professional-grade dark wood filler for deep repairs. No shrinking/cracking, usable indoors & outdoors. Drills & screws post-cure.
The Ronseal High-Performance Wood Filler is a premium-quality, chemically bonded filler and catalyst combination designed for extremely tough wood repairs. Unlike standard fillers, it won't shrink or crack, providing long-lasting repairs for both interior and exterior wood damage.
This advanced formula can be applied to any depth and remains fully workable after curing – allowing it to be drilled, screwed, or planed to achieve a perfect finish. Its ultra-durable protection makes it ideal for structural repairs in high-wear areas.
