Gardner STA-KOOLElastomeric white roof coating is a quality flexible, white acrylic latex roof coating. This product resists cracking & peeling, while protecting underlying surfaces. It expands and contracts with the roof’s movement to resist damage. The coating provides a protective barrier which reflects the sun’s heat and destructive UV rays. In turn, this helps to cool roof surfaces and reduces interior heat gain and lowers cooling costs.87% reflectivity keeps roof surface coolExpands and contracts up to 300%Better hide and adhesionSiliconized so finish stays cleaner longer
