It's the first thing to check, because many pole barn slabs were poured straight on grade. Tape a 2-ft square of plastic sheeting to the concrete for 24 hours, for large floors do it in several spots — condensation or darkening underneath means moisture is rising and you need our Moisture Sealing Epoxy as the first layer, or the coating will eventually blister. If it's dry, standard prep proceeds. The tiles don't care either way, which is another reason they're popular for pole barns.
