Answer 2

You can float a thinset mix to wall if you like, but there is a much easier method now. Wall tiles (and only wall tiles) are generally adhered with an adhesive. Spread it on with a trowel (same trowel as in the floor application) and then do the notched grooves and stick your tiles to it. You can do a thinset (mortar board cement product) in the exact same method. Both are perfectly acceptable, i just find the adhesive more forgiving and easier to work with.

Answer 3

You should be using thin set mortar. Use a .25 inch notched trowel to spread the mortar. Mortar should be like wet mud, hold its shape when troweled.

You dont say what surface your are going on. usually, a tile backer that is cementatious in nature is the standard.

My showers, I put felt paper like used in roofing on the walls, half lapped. I then put duroc board over that with course thread screws. I taped and mudded the screw heads and joints using superflex thin set mortar. I then used the same thin set troweled on with a quarter inch notched trowel. Back butter the tiles with a thin coat of mortar to insure good wetting, work the tile into the mortar a bit to set it. You will need spacers to hold the tile from settling.

Answer 4

are you talking traditional wall mud mortar method?

then you need to know how to lath and then how to scratch and float up a wall for preparation for recieving tile

go to john bridge's ceramic tile forum and you get the 411 on how to lath ands float a shower wall

mortar beds and walls are considered by old timers any any professional alike as the best method for tile, CBU ( cement backer units ) are good but cannot compensate for uneven walls ( unless you shim behind the cbus ) like mortar bed / walls can. mortar beds / wall are considered forever tile instalations and is somewhat a lost are as few contractors now a day even know how to do it properly.
