Applied to 2 car garage yesterday evening. Easy to apply, but i will suggest keeping a paint roller handy as the product will produce white beads if applied to heavily. Dries to a very low lustre and you can actually feel the barrier film if you run your fingers across it. Pay close attention to the area you need to cover compared to the amount you purchase- it covers what it says it will cover. My 2 car garage used every bit of two gallons - if you have an extended garage or wider width garage, you will need more and it might be more economical to just order the 5 gallon pail.
