I used 2.5 car garage kit for my 1 car garage (little bigger abt 250sq ft). I used double coat and am happy. Would recommend clear coat on top for more and better life of epoxy. Good luck!
We ordered 3 (one car size packages of RockSolid Polycuramine coating (dark gray) for our double car garage. Only because the 2.5 size was out of stock. The package comes complete, which includes the concrete etch. The coating looks wonderful, and easy to maintain. Their is no smell and drives within a day. We have tried other products in the past but this truly is stronger than epoxy and more durable. We just love it! Thanks to DTEPs and their wonderful customer service.
