Epoxy you’re looking at $5-$9 a sq/ft. Just because it’s new does not mean it’s going to be cheaper. I am looking at this also for my new barn and at 2400sqft, I’m prob going to hold off right now.
Everyone has told me to let the professionals do it. The store bought kits will peal eventually.
Lift I don’t know much, but I want one also. Is your floor rated to handle it? I went with 6” cement to ensure it can hold my F350 on a lift.
