Teneur en matière sèche:


Fastfiller is used for efficient and durable repairs of cracks and knotholes in wood prior to finishing. It bonds tightly to the wood, is easy to sand, cures fast and does not shrink or crack. The filler is powder-based and designed to accept stains, oils, wax and lacquers very fast and naturally, creating a uniform and natural look. Fastfiller is an environmentally friendly product based on pure natural raw materials, 90 % animal proteins and mineral components, and it must be mixed with water before use..
