Tiling over Original 1970 Mud Bed for Bathroom Remodel
Been reading the forums for quite a while now and this is my first post.
My mother would like to replace the original tile floor in her bathroom with new porcelain tile. The floor is 40 square feet. The house is a bi-level in Northern NJ built in 1970. The bathroom room is on the main floor with the garage below it.
I removed a couple of tiles to see what is underneath and I had a tile contractor at the house today. He said that he would do the following:
1. Remove the rest of the floor tiles
2. Spread the thinset on top of what he called the existing "mud" base that the original tiles were placed on.
4. The floor is not flat, there is a little bit of bevel in it. He said he would "build up" the floor to flatten with what I am assuming is the thinset.
3. Put the new tiles on top of the new thinset.
Kindly seeking everyone's thoughts and input on what the contractor said and how this job should be done properly.
