CoolCoat Insulating Coating has Ceramic MicroCells to reduce heat transfer, known as heat flux, to the coach interior up to 29 Percent. CoolCoat reflects and dissipates solar heat with tiny yet indestructible vacuum spheres to reduce A/C demand. Use with Dicor Rubber Roof Cleaner/Activator for proper adhesion. The EPDM Roof Cleaner/Activator is the first part of a two-part, commercial grade system that combines the cleaner/activator with our acrylic coating. The cleaner/activator prepares the roof while the acrylic coating provides an excellent, long-lasting protective barrier. The two together form a "lock and key" effect to bond the coating tight to the old roofing. Made specifically for your RV EPDM rubber roof, the conveniently packaged cleaner/activator is ready to use and easy to apply.
