Mathys Fassitek is a solvent based wood stain with a base of special alkyd resins. Mathys Fassitek stains are very effective in impregnating wood and protecting many types of wood from weathering and UV rays.

Mathys Fassitek can be applied to both new and previously treated wood, is easy to use, transparent, light-stable and really do justice to the wood grain, resulting in wood that stays looking beautiful and natural for a long time. There is no need to worry about peeling or blistering because Fassitek stains are not film-forming and highly breathable.
