Help!!! LOL,
Hey Guys, I am a roofing contractor in Tampa,I have a guy doing some foam work for me on several large flats. The flat ares are a granulated membrane, My questions are the roofs have large blisters do you recommend having the blisters repaired before spray of foam?? The company I have spraying, tell me just to cut and spray over with no repair!! also should he be using a primer before spraying. thanks for any info. |

You can "X" the blisters and nail or screw down the flaps. Or cut them out. Foam makes a great repair tool. No primer is needed due to the tenacious adhesion of SPF (unless the substrate is unusually dirty or dusty or chalky). have fun, olger |
