Mosaic onto kitchen unit

[jstrats]

Hello stars of the tiling world, hope everyone is well, been a while since i posted on here, need a bit of advice, hope someone can help, customer wants to tile kitchen units in mosaic (see pic attached) she wants to construct the unit out of ply, i have suggested sticking 4mm Marmox on top of this prior to tiling, how would you go about this?

Also she is having UFH and using the following method:
- We'll ensure the existing floor is absolutely level first (use self-levelling compound)

- Thin foil insulation
- Polypipe Overlay 18mm screed panel with pipes
- De-coupling layer - Dural DURABASE CI++ matting
- mosaic tiling on top

Anybody see any flaws? Do you think this method would be ok with thin white ceramic mosaic?

Muchos regards, Jamie.

Actually i've already spotted an error, we can't put 4mm backerboard on ply as it would make the uprights at either end of the unit too wide.

Could we make the whole unit out of Marmox?

You sould be able to use Marmox or Kerdiboard

What would be the thickness you recommend? Customer wants a single mosaic tile running on front edges and tile is 25mm, do any of these boards come in that size?

 

[White Room]

They do a Kerdiboard at 27mm thick....

 

[jstrats]

Found boards that are 28mm, can you stick tiles to the front edge though?

 

[lizzardtong]

you can use two 12mm boards I think.

 

[jstrats]

Good thinking, can i stick a tile to the front edge though?

 

[lizzardtong]

yes you can just get some fiberglass mesh and adhesive for that edge. or you can make sandich out of 10mm board 3mm of adhesive and and 12mm board. that the mesh what is used to make that boards 2x Fiberglass Mesh Rolls 100sqm REDNET C145 for plastering & rendering FREE P&P | eBay

ok that sounds like a plan.

Any thoughts on the UFH? Will the Dural matting be suitable for thin mosaic?

 

[lizzardtong]

give them a ring as I couldnt find anything in data sheet. from the other hand. will you need decoupling membrane for mosaic?

 

[jstrats]

I believe this is what the company supplying the polypipe panels have recommended.

 

[White Room]

For white glass mosaic you will need a white backing otherwise any dark material will change the colour.....

 

[lizzardtong]

yes but for normal tiles so the wont crack. but mosaic 2.5/2.5 it wouldn't. but wait for others more experienced members advice. as its only me thinking.

I am going to sleep on this and ask customer more questions tomorrow, thanks for your help so far.
