Gardner(R) STA-KOOL(R) Elastomeric 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.
