Thin-set or wet-bed mortar mix?


Hi,

I am renovating a bathroom in a house built in the 50's

Behind the tile is a very thick, 3/8's - 1/2" wet bed of sand and cement (it looks similar to concrete as it has little pebbles within it)

The old tile only went about 3/4ths of the way up the wall in the shower.

Because of this, when i took out the old tile, the wet bed is protruding past the rest of the wall (the 3/8ths to 1/2" i mentioned earlier).

However, i wish to install new tile all the way up the wall, not just 3/4ths of the way.

At the tile shop, the manager told me to rough up the surface of the cement board wall, put a primer on it, then put on thinset so it will become flush with the wet bed.

Questions:


1. Should i use thinset to bring the upper wall flush with the wetbed? Or should I use a sand and cement wet bed mortar mix?

2. When i am smoothing out the existing wetbed, should i use thinset or a sand and cement wet bed mortar mix?

Thanks,

Scott

All of that is asking for trouble.

I would take it back to the studs and start over. You aren't saving anything by trying to salvage those remnants.

I forgot to mention that there are no studs anywhere.

behind the wet bed on one wall, there is a solid wall of cinderblock

behind the wet bed on the other walls, are sheets of cement board and no studs anywhere, i know, makes no sense

I can't see the actual wall structure in those pictures.

Thin-set or wet-bed mortar mix?


I decided last night that, that is what i should do

I am tearing out the walls.

I discovered that, in fact the shower/bath area does have studs. However, the back wall might be layered as such (cinder block, cement board, wet bed)

What is the best way to remove the wet-bed on that wall without destroying the cinder block?

If it were my work---I'd peal all that old plaster off--add studs to get the wall flat --then pit up new drywall and Durrock---

Trying to save the old will yield poor results and much more work ---

Thin-set or wet-bed mortar mix?


Oh' Mike,

The back wall (shown in the picture below), I am not sure if i can remove the wetbed made of concrete. It is very difficult to chip, and on top of that, it is the only wall where there are no studs behind it.


The wall is built up as follows (from inside the wall to outside):
Cinder blocks > Cement > Plaster > Wet bed/ concrete mix

I am thinking about the following options

1. attaching metal lath to the painted portion of the wall and applying mortar to make the whole wall flush and smooth

2. attaching cement board at the right thickness to the painted portion of the wall to bring it flush with the wet bed. Then attach another piece of cement board over the whole wall to have a flat surface to begin to tile over

3. Grind down and remove the existing wetbed which is right over the cinder block (I have no idea how to do this step without chiseling the wet bed every day for the next 5 months)

4. What is the proper way to do this (to make a flat surface i can tile over)? without spending an eternity chipping the wetbed. I believe if i chip it away, which will take forever, i can easily damage the cinderblock.

For what it's worth if you decide to remove the cement by chiseling. A number of years ago, I wanted to remove a layer of aggregate that was bonded to my front walkway with epoxy so I could replace it with tile. I started by hand chiseling and it was clearly going to take the "next 5 months". I rented a hand-held power chisel and finished the job in a few hours.
