Contamination of wood can come in many forms. Dirt, pollen, animal waste, but also air pollution will all contaminate wood and serve as a food source for moss, algae, mildew and fungi. These micro-organisms penetrate deep into the wood and build up on the surface.
Woodseal Pro prevents contamination by sealing the pores of the wood fibre. The penetration effect in the wood is extremely deep, making the pores themselves completely waterproof.
