Damp floor.
The floor is just damp under the linoleum If i dig up the loose spots, it dries out in an hour or so. I don't want to put down tile over a floor that accrues water. It would just loosen anything I install. I'm leaning towards 6 mil plastic and floating 3/4 .underlayment on it. Covering it with a 1/4 masonite , and tiling with composite. It should last as long as the lineoleum that was put down 25 or 30 years ago. Any other ideas?
