Basic Uses & Description: SL 800 Surface Leveling Coating is a 100% silicone coating with a red color and a slight odor. SL 800 is designed to be used as a surface-leveler on roofing projects in which the surface is too rough or uneven to apply a roof coating, such as gravel surface built-up roofs and “alligatored” areas of a smooth surface built-up roof. This coating can be applied to the roof surface via heavy-duty airless spray unit (recommended) or rolled on. After application, SL 800 will settle into the lowest points on the roof and provide a smoother surface.
Composition and Materials: SL 800 is a dispersion of silicone rubber. This coating is a one-part, ready-to-use material that can be applied easily to a dry, frost-free surface, and cures at normal temperature and humidity in 4 to 48 hours (depending on thickness) by reacting with moisture in the air. For applications with lower than normal temperature and humidity levels, expect the cure time to be longer.
