Adhesives for Ditra and Porcelain

[PJPro]

Hi All.

I am about to start tiling my hall. The floor is concrete & screed. The plan is to prime the slab with APD, bond the Ditra matting to the slab with Mapei Keraquick S1 and then use Mapei Mapeker to bond the large format porcelain tiles to the Ditra.

I am confused about the modified/unmodified guidance from Schulter depending on whether you are US or EU based. Will my planned adhesives be OK or should I be using something else?

Regards, Phill

Why not use Keraquick for the lot? Mapeker is fine, but not as good an adhesive IMO. Just follow the UK fitting spec and you wont go wrong.
When you say large format are you referring to thin porcelain or just large tiles?

Tiles are about 10mm thick. 400 x 600

Mapeker is much cheaper than Keraquick, hence the decision to use Mapeker (if it is suitable)

Dont skimp on adhesive.. As Geoff, S1 all the way for me, and in this weather would be using a standard set like Keraflex..

I did the Schluter course recently and their advice is to ignore what's on the US website about using a non-modified thinset to stick Ditra down. Here in the UK they advise using an adhesive that's suitable for the substrate it's going down onto.
