A lot depends on if you use a vapor barrier under the concrete and how long it has been allowed to cure/dry. Coat it too soon and you will have issues. It takes at least 30 days for the concrete to cure and if no vapor barrier is used, there may still be some moisture coming up through the slab. We used to tape a piece of plastic visqueen about 3' square over the slab in a few locations and let it sit for a day or so to check to see if any moisture is still present. If the slab is completely dry than the Armorpoxy coating should work fine.
