Placed in our 2 car garage and it looks awesome. We put down roofing paper first and laid on top. I would recommend to cut down noise from the tiles hitting the concrete. This also gives a softer feel when walking. Be sure to leave the 1/4" around the edge as they do expand when the door is open and sun heats them up. Before laying we painted a dark brown all around the edge so give it more of a trimmed finish look due to the gap. We are still able to power wash our floor and the water does not pool. I would recommend to anyone looking for a nice finish in their garage.
