SEK-Surebond SB-8700-P 5 gal Wet Look Joint Stabilizing Sealer is a solvent-based advanced premium acrylic sealer that is "rain safe" 90-minutes after application and will not yellow under exposure to sunlight. It is recommended for outdoor use only, on old and new, horizontal or vertical surfaces to provide surface protection and stabilize newly installed joint sand in one application process. SB-8700 can be applied immediately after surface installation, as it is breathable and will not trap naturally occurring moisture or efflorescence. SB-8700 protects the surface from salts, acids and other corrosive chemicals as well as minimizes overall surface weathering and deterioration. On a newly installed or restored surface, SB-8700 will deeply enhance surface tone with a wet look, semi-gloss finish and provide stain resistance which makes cleaning and maintenance easier. SB-8700 is specially formulated with an antifungal designed to inhibit the growth of mold, moss and algae on the sealer film. SB-8700 has the consistency of water and dries clear with semi-gloss finish. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (82°C).
