COATINGS OVER SINGLEPLY MEMBRANES? YOUR THOUGHTS!

We have sprayed over EPDM and TPO and a few others what do you guys use to fix them?

with poly in the mix and a 15 gallon spec ponding water does not affect cfe if properly installed, remember cfe 15 gallon spec should be a minimum of 150 mils. most of them I see failing in ponds are due to not being cleaned enough or to light of spray. we have sprayed irrigation canals lumber ponds most are still holding tight. I looked at a roof my dad and larry did almost 50 years ago with cfe and base ply for 50 years old it still held out the water.

we don't primer anything we spray. we did 400,000 square feet of epdm its on our website and youtube. Clean clean clean!!!!

sorry for no response been a long week yes we take winters of its hunting and fishing season, and yes epdm is a great candidate for cfe we have been spraying over it for 20 years there are a few things to take into account but it seams to work really well just make sure if you spec 15 you put 15 don't spec any less.

Like many systems..... the enemy of CFE over EPDM is, ponding water.

Tim: Do you have to clean and prime first? I'm planning on shooting some on some scrap single ply at the shop to check it out, although I've been saying that for months.
