I'm about to lay Karndean tiles on an anhydrite screed which has hot water underfloor heating. The screed is thoroughly dry and has had the laitance removed. The tile supplier advised priming with Uzin 360 and then smoothing with Uzin NC110.
My questions are:- the surface is already smooth therefore why smooth it again? and because NC110 is also gypsum based, would I need to prime again with Uzin 360 before applying the Karndean HT adhesive?
If I was to go the Mapei route and use Eco-Prim T primer, what would be the next stages in preparation and tiling with their products?
