Ronseal High-Performance Wood Filler White 1kg

Ronseal High Performance Wood Filler is a durable, two‑part filler and catalyst designed for tough repairs to a wide range of wood damage, for interior and exterior use. It fills holes and cracks without shrinking or cracking, and can be used on surfaces such as window frames, sills, doors, and door frames. Available in Natural, Dark, and White, the product comes in a 1 kg tub and dries to a hard, finish that accepts stains, varnishes, and paints for a seamless result. It can be drilled, screwed, or planed once dry and typically sets in about 30 minutes, enabling faster project completion. The filler is suitable for deep fills and can be used for repairs where depth exceeds 5 mm, with the option to mix with a hardener for better adhesion on rotten or soft wood.

Usage

Before use, remove soft or rotten wood and treat with appropriate hardener if needed. Mix a small amount of hardener with filler until uniform in color. Test on a small area to confirm color and adhesion. Fill holes or cracks, leaving the surface slightly raised, and allow to dry before finishing as desired. The product is then ready to be sanded, drilled, nailed, or screwed, enabling a seamless final finish when paired with compatible paints or coatings.
