Finally got this deck material layed down. The product advertises 1 gallon will get you 2 coats of 50sq ft. I got 120+ sq feet/2 coats per one gallon. Not sure what I did wrong. Used a drill mixer to mix the stuff really good. poured into a roller pan. Used the tuff coat roller and really gooped it up. I couldn't get any more product on the roller and it went over double the coverage area advertised. Not complaining... the deck came out really nice. Used 2 gallons and 4 coats. But now I have 2 extra gallons of product at 70 bucks a gallon, thats 140 bucks invested that I didn't need. But I'll find a use for it. Really a great product!!! 2nd time using it but first time on a large scale project like my ULTIMATE FISHING TOON.
