Jaydub Posted: Sep 20, 2017 12:58 AM	Re coat spf roof Hi there I bought an old building about a year ago. It's a flat roofed 1600 sq ft building with an spf roof that I want to recoat. There are several places where the foam is showing through now and I've tested it in places with a coat of Gaco flex and its still showing tiny blistered and has some pin holes. Gaco is more of rubbery silicone texture than the previous coat used and I'm not 100% of what the previous one is. I read that if the original coat is acrylic or urethane then silicone can not be used over it. Can anyone confirm this ? Also is there a product you can recommend that's durable and not very expensive? I can message some pictures if you'd think it would be helpful. Many thanks for your help.
