Protek Timber Eco Shield is a new innovation in wood treatment technology. A water-based, micro-porous treatment that creates a long lasting waterproof coating for your wooden items. Timber will expand and contract throughout the year as temperature and moisture levels change. Micro-porous paints and treatments allow timber to breathe. Clear can be used as a top-coat over a colour, or use multiple layers to protect the wood but allow the natural colour of the wood come through.
