30g A unique two-part system that creates seriously tough repairs to virtually any interior or exterior wood substrate. You can fill to any depth and even drill, screw or plane to finish. This is a two part system where the catalyst hardener is used to activate the filler. A small tube is supplied in the top of each filler pack that you purchase, but a 30g tin of hardener is available should you run out. You only need to use a small amount of hardener to activate the product, it’s about a pea size of hardener for about a golf ball of size of filler. Show more
