Doing a bathroom remodel and started breaking up all the floor tile when we realized there's some sort of fabric between the tile and the plywood that seems nearly impossible to get off.
As you can see from the attached image, all the tile came off, but the mortar stayed.
The "fabric" (no idea what it's called), was somehow glued or stuck directly to the plywood and I'm pulling the stuff up by hand might take 'til next year.
So, what are my options now? Is there some way to sand through the mortar AND the fabric so I just get bare plywood? Or will I just have to cut out the plywood and relay the flooring so I have a flush surface to work on for the new tile?
