If you want to insulate and tile the floor at the same time I would recommend our Orby insulated Tile Backer board. The 50mm board will provide a high level of insulation and an excellent surface to tile. The finished floor level for a 10mm thick tile will be 63-65mm if the board is mechanically...
1. Dot and Dab is laying 2cm porcelain onto wet mortar dabs, Adpeds is laying screed pedestals that have to dry before fixing porcelain with cement based tile adhesive.
2. Dot and Dab has variable sized dabs with no cross support between slabs. Adpeds have same sized pedestals that cross link...
Placing mosaics in a thick bed of adhesive will often result in a flat wavy surface. A thin bed is likely to give a better finish, but this will then be below the surface line of the tiles. Use Mosaic wall spacers toavoid this.

I would agree with Tony. The new Kearkoll Fugabella is a resin/cement hybrid that does not need any special cleaning. It comes in 50 colours with matching silicones for the wall/floor junction.

Use a cement based tile adhesive. You are using ceramic and not porcelain tiles so a standard set or a ready mixed. Available through us or a local store.
Norcros one part flexible, BAL White Star or Kerakoll Biogel would all work.

You could use a liquid dpm. However, sealing in the damp problem could then lead to damp moving up the wall. Previously the gaps in the vinyl tiles may have been sufficient to prevent this. Probably over complicating this but worth considering.
The vinyl tiles may have been acting as a barrier to rising damp. You have removed them and the surface has dried but the screed could still be wet and the damp still rising (but evaporating before it looks wet). Adhesives and limestone can be fixed to a damp screed, but you really need to get...

10mm solid bed will be difficult with a trowel. The trowel suggestion I gave would give you 5mm, so back butter a 5mm layer plus the trowl on the step will get you close. I am not sure the tilers on the site would agree with me though... I think there may be a more elegant solution.
If the concrete steps are dry sound and plumb you need to fix the tiles with cement based tile adhesive. Make sure you achieve 100% coverage, the minimum thickness of bed will be about 5mm. Back butter the tiles and lay into a combed rib using a solid bed trowel. Consider your edge detail on the...

Are you laying floorboards over joists, or plywood over floorboards that are already in position?
Depending on the answer a good solution would be to lay 10, 12 or 20mm Orbry backer boards over the floor and tape the joints. This will provide insulation which will reduce the cold coming up from...

Orby 2400x600x12 or 20mm backer boards work well and the long solution is a time saver.
