Hope this helps i found it on another website,so?
We use polyaspartic polyurea often, but 98% of the time as a top clear coat on a garage floor only. The fact is, you can get the best of both worlds by using epoxy flooring as your base coat and polyurea as your top coat. You get a final garage floor coating that will stick to the floor through high moisture vapor emissions, and the increased durability of a polyurea top coat.
I am sure some of the flooring experts on here will chime in soon!
