I'd rather not replace the plywood if I can get away with it, as I'm under the gun to get my house on the market. Can the chips be sanded or filled in? If so, does anyone have any helpful hints on how to get the mortar up? I just found out that there are such things as chipping hammers and power scrapers. My old man has an air compressor, so the chipping hammer might be an option. I didn't find out much about power scrapers. Are these suitable to use on plywood?
Thanks in advance for your constructive replies!
You can not tile over the plywood, you need a backerboard and maybe some more plywood first, but from reading your other thread, I won't waste my time asking what you have for a subfloor.
