SUPERDECK® Deck & Dock is the perfect way to refinish old and damaged wood, composite and concrete surfaces instead of a total replacement. Deck & Dock helps beautify and protect and can stand up to extreme weather for years. The product can repair, resurface, protect and waterproof. It has a high build, flexible elastomeric formula and fills dimensionally unstable cracks. The product locks down wood splinters and helps smooth rough surfaces.
