 Right, so the best thing to do in a situation like this is to use a very good quality primer, either an alkyd primer or a solvent-based primer, because it tends to seal in all of those wall and ceiling surfaces, including the odors that are underneath. The other issue, of course, is the floors. Now, you mentioned that there's a tile floor there, so it was a hard surface floor? Yeah, right now we pulled up everything and we're down to the plywood, and we were just going to put in a new flooring. So is there anything we should do before we do that? Yeah, I would also prime the plywood. Okay.
