I have a small section in my house that acts as "utility closet" that does not have tile like the rest of the adjacent environment (sorry for the junk laying around):
My plan is to use some leftover tiles I have found in the shed and finish that part. I am unsure what I need to do, in order to affix the tile to the substrate that is some old vinyl and direct plywood where that is torn. This is a detail picture of how the rest of the floor:
To me it looks like they used thinset directly over the vinyl.
I plan to renovate for real this house in a few years, and the current floor is in a pretty good shape anyway, so I don't want to go overboard.
Can I just:
- Fix the holes in the plywood with similar material
- Apply thinset, tiles, and grout
It does not seem they used backerboard or uncoupling membrane for the rest of the floor...
