Alpha Chem Decking Sealer is a quality clear sealant formulated to provide an adequate water repellent barrier for the protection of timber decking. It will waterproof and protect any smooth or ridged hardwood or softwood decking timber, including pressure‐treated, pre‐treated or preservative impregnated timber. It can help prevent drying, wetting, swelling, splitting and cracking of the timber, whilst at the same time allowing the surface to breathe, and moisture inside the wood to evaporate.
