Ideas to protect a new cement floor

[dean from bozeman]

I'm just about ready to move from my two car garage into my new shop. It is important that I protect the new concrete from oil, gas and other liquids. What products have you folks used successfully (and unsuccessfully) to protect your concrete.

I did a search on Fordbarn and found a thread from the V-8 site that was from 2010. The best suggestion in that thread seemed to be a vapor barrier under the concrete and a relatively inexpensive paint product from Rustoleum on top.

This floor needs to be protected because the future use of the building will be to hold meetings, events, etc. similar to our barn (1915barn.com).

Any advice will be greatly appreciated.
