The original Knot Filler System

Knot Filler is a unique product for repairing all kinds of knots, cracks, splits, defects, etc. in wood. It is easy and quick to use, durable, flexible, and strong at the same time. Knot Filler is both water-repellent and flexible, which also makes it perfect for outdoor use. It is a non-toxic product, safe for the user and the environment. 

Knot Filler is a unique wood repair product with many advantages. First of all the impeccable result. When using the correct color the repair will be very hard to spot when the finishing treatment has been applied. Knot Filler works with oil, lacquer, paint - even stain. We have a variety of great colors to match most wood sorts.

The durability of Knot Filler is amazing. Knot Filler is made from polyamide and will stay in the wood year after year due to its flexibility. It expands and contracts with the wood, making the filler very suitable for outdoor as well as indoor use.
