A professional grade sealant for concrete. It is a 1 component, polyurethane, self-leveling sealant for contraction/expansion joints and cracks in concrete floors and decks. It cures in place to form a highly resilient and abrasion-resistant seal, which resists deterioration caused by weather, stress, movement, traffic and water. It's abrasion and tear resistance makes it ideally suited for applications exposed to pedestrian and vehicular traffic. Recommended for driveways, garage floors, concrete floors and decks, and sidewalks. Not recommended for vertical surface repair (use horizontal surfaces only). Underwater applications or permanent water immersion. Use in areas of high chlorine concentration such as around swimming pools. Applications requiring temperature resistance greater than 180 deg. F (82 deg. C). Joint depths greater than 3/8" (9.5mm) the sealant may bubble if applied too deep or if substrate is not absolutely dry. Use with fillers impregnated with oil, asphalt, tar, or any other migratory saturant. Contact with oil-based caulking compounds, butyl caulking compounds, and silicone sealants (uncured and cured). Exterior applications when rain is expected before sealant reaches initial cure. Aircraft runway or tarmac use. Coverage: Approximately 86' at 1/4" bead. Uncured adhesive clean up: Mineral spirits. Cured adhesive clean up: Cut or scrape.
