Hi guys,

I woundering what type of adheshive i need to lay slate tiles on a conrete floor. The slate tiles are the type theat are very natural looking on the face but have a perfectly flat back on them. I assuming the normal type ceramic adhesive is not enought due the tiles being non porous. Am i correct and what do you recommend. Would like advice on grout to please. This is for a kitchen floor.

also, I will be using the same tiles to tile a wet room. I will be laying 18mm ply down and then tanking the room. what adhesive and grout is best for this application

your advice is much apprciated

Hi and welcome...I take it you mean calibrated slate, a single part flexible adhesive for the screed floor...

i'd overboard the ply with cement/insulation boards before tiling. and welcome btw

and I'd get someone in to do it for you.

They will need sealing before laying also.

hi beesley as above and whats your plans for the wetroom do you have a goodplumber involved?

Some waterproofing wouldn't go astray

it sounds like they're machine cut, ie not riven on the backs, this doesn't mean they're callibrated, what's the thickness variation?
