[Lee@emctiles]

As for your knowledge, I’d be inclined to call you before many of the so called Tech advice lines out there. Your knowledge is top class!

Will take that all day long Andrew, nice comment from a TTA Tiler of the Year Nominee!

So, theres been a slight plot twist in this 270m2 floor.

Turns out the screed has been commissioned and UFH turned on, however the laitance hasnt been removed. Tiler has hired machine to sand but not getting anywhere. (i know its baked on)

Anyone with a suggestion for what can be used? @Ajax123 ?

Hi Lee Wet diamond discs. My friend did one for me that was down for 10 months no probs

Not a straight forward answer. I have got a couple of these going on at the moment. I usually recommnd the turbo disc from SPE Ltd which fits most screeds to produce a key. Even that has failed to cut through the two in question. I guess the only sensible answer is treat it as a non porous surface like a powerfloated concrete in terms of primer. Or use a primerless system. As unprofessional As it might sound I have found pre mixed tubbed adhesives really useful in this sort of situation but that is not to proper tilers tastes generally especially on a big floor. It' about getting the primer to wet the surface of the screed and not just sit on top. If the primer soaks in then a gypsum based adhesive will be fine. If the primer sits on top then use a different primer. Epoxy can be useful here.
