"Ordering and customer service was great. I followed instructions closely (temperature, prep, etc.) on the 700 sq ft foam kit and mostly everything went as planned. Had a hard time getting the proper depth on my ceilings. Spraying with the normal tip at 12" from the roof was a lot of work to cover my 400 sq ft of cathedral ceiling. It seemed like I wasn't getting full expansion of the foam on the ceiling so I had to re-coat an extra time. Walls worked well and were much easier to get a nice 1" layer (after expansion) without too much trouble. This was my first time using a spray foam kit, so maybe I did something wrong, but I don't know if I'd try a ceiling again, walls seemed pretty easy."
