Airless works just fine. Get yourself a big ol' tip in your gun and you're good to go.

Re: Spraying Elastomeric Roof Coating


Fast set elastomerics work great and provide a pure monolithic membrane. We used a 2 component machine from a company in Ohio that was very cost effective and put it down fast. The real neat part is you can walk on this stuff in minutes compared to other types and weather isnt a real issue, providing the surface is dry, due to it curing exothermicly; chemical reaction. The coating has aluminum powder in it and reflects UV rays to the point of 30-40 dgrees cooler than any other roof product weve seen.

Some people don't care for the two component machines but we had no issues. This one project paid for the rig and still had steak for dinner

Depending on the type of coating, you should be able to use any sprayer that is strong enough to atomize the coating. If you are leaving the sprayer on the ground, keep in mind that you will need a strong sprayer to push the material up and through the hose. Graco 5900, 7900, and gas-hydralic rigs all should work.

Graco
BulldogŪ 33:1 & 41:1
Air-Powered Airless Sprayers

this pump will move some material fast. you can run 6 lines off it easy for Uniflex, Dryfall, whatever material you need 6 guys spraying with.

We own 3 similar units and have had no problems with them. If you want more info google the Bulldog 33:1 paint sprayer.

Excellent advice and remember to remove filters from gun(s) and pump.

Any commercial size sprayer will work. I know we have had to use a graco x9 airless sprayer... just make sure you have a larger tip you will be fine... ERNIE’S GUTTER
