Hi

 

We have UFH with liquid screed poured on top. I recently had a quote for glue down LVT. I got told that glue down LVT does not stick well enough directly to liquid screed even if the laitance is removed (whether by sanding or grinding). He said it'll start peeling off after a year or so. He insisted that we prime and then pour a couple of mm self levelling compound on top of the existing screed before installing glue down LVT. 

What do you guys think? Is he correct?

 

Thanks

He is correct.

We had Cemfloor completely level and flat with no ufh and the flooring people still did a thin coat of stuff before the lvt.

Hold on to this chap with BOTH hands.

Our fitter insisted upon two stages of self levelling compound/feather edge on top of the liquid screed
