Olympic 56400A/01 Maximum clear Waterproofing Sealant
Olympic is another oil-based product, which soaks into the wood much like Thompsons does. Although they offer tinted versions, this clear contains advanced UV inhibitors, which actually work better than the tinted versions. It also protects against mold, mildew and algae. It also has a scuffguard formulation which protects the wood from discoloration caused by scuffing and scraping. The product is guaranteed to protect water damage and graying for a minimum of two years on decks and three years on fences and siding. It is 100 percent VOC compliant.
