We have stained concrete in a cabin, in the basement with in-floor, radiant heating. I like the color generally. Biggest mistake we made: following the directions to wash the concrete with TSP first. Subsequently, we could not get the TSP sufficiently rinsed out of the floor (even with vinegar) and there are areas the stain did not adhere. (TSP is a strong base and the stain is an acid.) I would do the stain again, but without ever using the TSP - there really was no need.
