THE CHALLENGE FOR WATERPROOFING WOOD
Water is the biggest enemy of wood. Absorbing and releasing water causes wood to swell and shrink, leading to substantial damage of the surface and structural integrity of the wood. This enables water to substantially accelerate the rotting process from the inside out.
All wood used for outdoor purposes should always be treated with a water-repellent impregnating agent or with a coating to protect it from weathering. Mostly, the effect of commonly used solutions, unlike Woodseal Pro wear off within a few years.
