Protect your wooden surfaces with the SmartSeal Wood Sealer. It is a professional-grade sealer specially designed to create an invisible waterproof barrier. This barrier helps prevent the ingress of moisture on pressure-treated softwoods such as fences, sheds, garden furniture and decking. This wood sealer is specially formulated to protect your outdoor wooden surfaces for up to ten years. The water-resistant surface will also inhibit the growth and spread of mould and algae, which is a big problem with softwoods, especially in shaded north-facing areas of locations with high levels of rainfall. To ensure the best results, all wooden surfaces should be thoroughly cleaned before the application of this wood sealer.
