DESCRIPTION: The Limestone (light-gray) color more closely matches newly poured concrete for good appearance. Sonneborn SL 1 joint sealant is a one-component, self-leveling, UV resistant, exterior grade, non-priming polyurethane sealant designed for creating, sealing and waterproofing all type of concrete and metal expansion joints up to 1-1/2" in width. It has 300 psi tensile and 800% Elongation.
