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.
