DEFY Crystal Clear Composite Deck Waterproofing Sealer, 1 Gallon

Product Information

After allowing the sealer to cure for 24 hours, we put it to the test. Water beaded up and ran right off, but the sealant offered hardly any protection from sand scratches. We considered the ability to dry rapidly as an asset if time is a factor. Within 1 hour of applying the second coat, the board was bone dry, and the sealer left no visible film on the surface.

While some people may not mind the rougher texture, those who want a super-smooth finish can lightly sand the surface with 240-grit sandpaper before applying the second coat of sealer.The sealer went on without any noticeable odor, and we applied two thin coats, the second 2 hours after the first. Then, we set the board aside for 24 hours to completely cure. The Olympic Stain + Sealant combo left a thin film on the board’s surface that imparted a slightly wet look even when dry. It repelled water, and while it suffered a few scratches from sand, they were minimal. After a month in the elements and cleaning with a brush and all-purpose cleaner, water still beaded up and ran off the treated section, and the wood beneath the sealer still looked new. Doesn’t offer much protection from scratches; may not be ideal for those with pets or frequent parties Sheen: While water-based sealers rarely provide a finished sheen on the wood’s surface, oil-based sealers will often impart a slight sheen.
