This topic appears on several other threads so do a search under "garage floor".

At the risk of being redundant, Bob is correct. If your building contractor did not put down a vapor barrier under your garage floor before he poured the slab moisture will probably seep up through your concrete.

That will make it impossible to get epoxy to adhere to your floor.

The way to test for this is to take a 1 ft square sheet of saran wrap, lay it flat on your floor and tape the edges down making sure it's airtight.

Check it the next day and if there's moisture condensed under the plastic you will likely have problems with epoxy coatings.

I applied epoxt to my floor 4 1/2 years ago and I'm very happy with it. Pictures are in my gallery.
