Condensation issue

That's a good idea. I hadn't thought of that.

Just an FYI, Home depot has a basic clear epoxy garage floor coat for about 25 bucks a kit and has anti slip additive with it if you wanted to use it.
Don't know how big your garage is, but I would expect you would need a few of the kits to do a reasonable size garage.

I used it on our shower walls.:D
You should see some of the stuff people are doing with that epoxy.
