Restores a Leaky Roof at the GTMO Naval Station

Clean for Good Adhesion

Aged aluminized asphalt coatings can interfere with the adhesion of elastomeric coatings. Kelvin Wilcox of South Georgia Coatings demonstrates how much of it needs to come off.

Unless you are installing silicone roof coatings, silicone residue will interfere with coating adhesion so think twice before caulking metal roofing screws with them. At least 2" around the fastener head needs to be scraped to bare metal.

GTMO takes their deadlines seriously and can mobilize the needed equipment and manpower to get the job done in a heartbeat. It got a bit crowded having 14 people on that roof.
