Ronseal High-Performance Wood Filler, Dark, 275g

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.
