Basic Uses & Description: SL 800 Surface Leveling Coating is a modification of our 100% Silicone Roof Coating with a red color. 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 should be applied to the roof surface via heavy-duty airless spray unit. Roll-applying is not recommended. After application, SL 800 will self-level into the lowest points on the roof and provide a smoother surface for Silicone Roof Coating application.
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 by reacting with moisture in the air. At normal temperatures and humidity, cure time is between in 4 and 48 hours (depending on thickness), For applications with lower than normal temperature and humidity levels, expect the cure time to be longer.
