Cool Roof Store Acrylic Coating

Product Description

Cool Roof Store Acrylic, is a tough,  highly flexible, white acrylic roof coating. This high performance product resists cracking, peeling and mildew, while offering tremendous durability and long term life.

It expands and contracts with the roofs movement to resist damage. The coating provides an excellent, highly protective barrier which reflects the suns heat and destructive UV rays.

In turn, this helps to cool surfaces and leads to a reduction of interior temperatures. This product is an “investment”, and can actually pay for itself in savings on cooling costs! Do Not Allow Stored Product To Freeze.
