Its abrasion and tear resistance makes it ideally suited for applications exposed to pedestrian and vehicular traffic. This sealant includes a self-leveling formula with no tooling required and cures gray to blend in for a professional finish. Loctite PL is a low VOC formula and meets strict federal and state guidelines.
