I'm trying to figure out how to finish the floor of the basement I'm ever-so-slowly fixing up. It's pretty dry - no water, and no drain either. I don't want to spend incredible amounts of money and don't want to run the humidifier. The foam I've put on the walls make it pretty dry in summer - no musty smell. I'm tempted to put an inch of xps foam on the floor and some plywood or osb on top of it, tapconned or glued down. Then, what on top, laminate? Carpet? Both prob. would need a humidifier, I imagine, but maybe not with the foam on floor. If there was a pipe break, or something, everything would have to be taken out, I imagine: big and costly job. An approach that seemed more rugged could be ceramic/porcelin tile or maybe staining the concrete. I've seen some nice stained concrete floors, but I don't know if I could pull it off right the first time. The floor would have to be acid etched, I guess as well. For tile, a lot of back breaking work, but it could look good, and material costs rival or are less than sheet or plank vinyl, laminate, engineered wood, carpet, etc. There's a fair amount of stuff down there I'd have to move to finish the floor, but maybe the tile could be done piecemeal, rather than the staining with all that swabbing. I guess I could paint it too, but the can recommended acid etching as well. Any suggestions?
