Concrete floor, plaster wall, concrete backboard: Thinset(s)?

I am tiling a bathroom with concrete backerboard around the tub/shower area, plaster over drywall in the rest of the bathroom, and a concrete floor. The wall tiles (all the shower/tub & ~ 3' of the rest of the walls) are going to get 3x6" ceramic, and the floor is getting 1x2" tiles adhered to 12x12" fiberglass "mats". I have a bunch of modified thinset for this, which the tile store says is sufficient for all 3 surfaces. Agree? Disagree?

Furthermore: I can't use DITRA under the floor tile because the 1X2s are too small. Should I worry a lot about not having that layer?

And another thing: The shower wall i took down was moisture barrier / drywall / plaster / mortar / thinset / tile. It was all dry as a bone and intact. I am planning on moisture barrier (leatherback) / concrete backerboard / thinset / tile. Is that suffient?


Thanks muchly,
Laine

Welcome, Laine!

MNodified thinset will be fine on all three surfaces.

You don't need Ditra for your concrete floor, unless you have come cracks. Do you?

I don't know what "leatherback" is (with the possible exception of sun-damaged skin), but if it is a moisture barrier, not an air infiltration membrane, then it's OK. Otherwise, you plans are good.

Thanks for getting back so quick, bbcamp!

No cracks, and as it is a fairly old slab now, I don't really expect any.

Leatherback is a brand for a moisture barrier often used on roofs.

I sanded the paint on the plaster - is that sufficient prep for the thinset there?

Leatherback sounds good.

Floor prep: Clean off any adhesive or paint using only mechanical means, no solvents.

Plaster wall prep: Clean surface with TSP based cleaner, then lightly scuff the gloss off the paint.

Oh yeah - I have no special corner tiles - for where the wall and floor meet. Does it matter which I lay first - the floor or walls?

Thanks for your help - I think I'm all out of questions!

OOps, one more... just found this in archives:
I want to put ceramic tile in a bathroom with textured, painted walls. I would like to know what special prep is required if any.

Darrel,
Not a good idea. If what you are talking about is a wainscot (half wall), you might consider adding another layer of sheetrock or cement backer board.
If it's going to be a wet area (shower), we need to talk.
John

Is he in disagreement with you about tiling over the walls, then?

I tested the plaster walls with a screwdriver; although the paint has come off in a couple places, they seem quite sound. No crumbling to speak of when I push at them with the screwdriver. So - am I ok to tile over this stuff?
