Hi again
we were last in touch around Christmas last year about laying terracotta tiles on a gypsum screed. We established that we needed to install the GSHP and dry out the screed before tiling. UFH has been running since mid March and is now at 25 degrees C so conclude it should be dry.???!!!
We'll seal the screed before laying the tiles.
The tiles are handmade and quite uneven so will need atleast a 10mm bed.
Options
Grouting terracotta rather than pointing, even after sealing them, seems a bit risky.
Many regards

Options
- 15mm-20mm sand/cement mortar with SBR latex additive to add flexibility. Pointed with same.
- 10mm PCI thick bed adhesive which we can either grout with risk of staining very porous tiles or could we point them up with mortar as above?
