Shoutout to a guy on a forum who told me to check the subfloor before laying tile
I was getting ready to tile a small bathroom floor in a house from the 1950s. A user named 'BrickandBoard' commented on my post saying to spend a full hour checking for any bounce or soft spots, even if the old floor looked fine. I almost skipped it to save time. Sure enough, near the toilet flange, I found a section where the plywood had gotten wet and was totally spongy. If I had tiled over that, the whole job would have cracked in a year. That one piece of advice saved me a huge headache and a call back. Has anyone else had a forum tip catch a problem you totally missed?
