Hi, I've had LVT planks laid on a concrete sub floor and it's clearly not completely flat - as in my dining chairs wobble depending where you put them, rather than it not being level/having a slope. It is visibly not flat in the light coming through the french doors. The installers agree it isn't flat and say it's because the subfloor wasn't flat and the variations in the subfloor aren't fixed by the latex layer as latex is not self levelling. They say it's not something they have come across before. I accept the subfloor was probably not flat as I've checked the adjacent room which still has carpet so I lifted it and that isn't flat. The room itself also had carpet before, so the variations weren't noticeable. The variations are probably up to about 3 mm at a guess. The installers say they could take the LVT up and put another layer of latex but it will likely do the same thing again. I have underfloor heating so I'm not keen to add another layer to be heated just for that to happen again. The manufacturer was a bit non-committal but said if it needed levelling and if latex were to be used for that it would need to have been at least a 6mm layer instead of the usual depth. I'm saying to the installers they should have checked and taken steps to make the floor flat before putting down the latex (e.g. using some kind of SLC?), but they don't seem willing to acept this. Am I right, or am I being too picky - I can live with it but don't really think I should. What should the remedy be (If I am right)? Regards Chris
Sure - not easy to show but see attached - the areas I have highlighted are not marks on the floor they are different levels highlighted by the natural light from the door in front
I would have seen those with out you marking them out ! Looks like trowel marks in the smoothing compound Should have been sorted out before the floor was laid I definitely wouldn't want to live with that
Judging by that picture then tonput it bluntly your fitters are trying to blag you. They could eliminated them trowel marks before fitting the floor. That has nothing to do with your original subfloor is unlevel, they just didn't want to put the extra effort in to level it out... Judging by the edge of your window wall they dont know how to screed! Is that screed on your skirting boards??
Dont settle for that and dont let them tell you that it's down to your original floor, no way should.you just 'live with it' Tell them if they had rubbed it down it would have got rid of them trowel marks
That’s a bit like having a crap plasterer in and him telling you it’s because the wall isnt flat Sent from my iPhone using Tapatalk
