What is Knot Filler?
Wood is a natural material, and each piece is unique—often with knots, splinters, or cracks that can be challenging to repair. Knot filler provides a fast, durable, and simple solution to repair such damage in a single application.
Developed in collaboration with the wood industry
Developed in collaboration with the wood industry, Knot Filler enables effective repair of knots, cracks, splinters, and other larger defects in wood. It delivers strong, flexible, and long-lasting results on all types of wooden surfaces, including floors, furniture, and windows. Ideal both for quick on-site repairs and for continuous production processes.
Knot Filler is the professional choice for very fast, strong, durable, and highly flexible repairs of larger wood defects prior to finishing. Most other wood fillers are designed for cosmetic wood repairs such as small nail holes, fine cracks, and surface scratches. It is easy to apply and ideal for minor touch-ups, but way less durable, time-consuming and unsuitable for large or structurally difficult repairs, unless toxic or reactive chemicals are added, such as in the classical 2K products.
