I've got some very well calibrated brazilian slate 400 x 600 x 10mm. The back is lightly grooved from the machining.
I also have some Dunlop natural stone and large format adhesive.
The substrate is sand/cement screed well dried (many months old) which is slightly dirty with a few paint splashes on etc. Not very dusty, but SOME light dusting if scraped, etc (like any screed).
Trowel I will use is large format trowel (20mm x 13mm rounded notch at 28mm spacing)
The question is:
Do I need to prime the surface before tiling ?
If so, with what ?
Thanks,
Simon.
