Hi, I hope you don’t mind me asking for advice. We are in the process of renovating and after lifting carpet and plastering we hoped to get some LVT laid but the three companies we spoke to said our floor compound wasn’t suitable and that no self levelling was either as it wouldn’t stick to it. One of the images shows the compound (after I had mopped it) which I suspect is some sort of bitumen screed. I got frustrated and decided to take it all up (discovering in the process that it co rains asbestos). The second image shows the floor now, there is a 20mm variance, some cracks and some gaps behind old DPM on the newer concrete channel. The older slab has no DPM. We can’t really afford to dig it up and replace the concrete slab. A surveyor has recommended a liquid DPM then self levelling compound. The flooring shop reckon that won’t work. I have a screed company coming tomorrow to take a look and I’d like to have some advice before I talk to them just in case I end up with some future problems. Edit: Have had to remove images due to posting restrictions
Already had that stress and rabbit hole but thankfully no, it’s the original slab. It had some sort of oxide on top which is an old primer.
Thanks, self leveller, dpm then more self leveller is what the flooring store suggested. Hopefully the screeding company tomorrow agree and I can finally get this floor sorted!
Company suggests the following due to the significant drop across floor (actually more like 45mm) and the additional cost of laytex. Does anyone know if LVT can go straight onto Retanol Xtreme. 1st day: clean the area and apply 1st coat of M-Bond 2nd day: apply 2nd coat of M-Bond and lay Retanol Screed (sand and cement based) at 45mm average depth.
Would be cheaper to put dowm a dpm sheet and pour in a 45mm liquid screed. If you have the time to wait for drying and the height. Or na with granno, dpm1c and top coat of na. But its not cheap for 45mm build up
