Hello, I am hoping the community can help with my confusion: We have been taking quotes for LVT in our ground floor, which is now carpeted. One tradesman discovered thermoplastic tiles underneath the carpet and recommended screeding before putting the underlay and LVT down. Another tradesman said they could do it without screeding because they are using a different kind of LVTs, which have an additional layer of latex (?) to them. He agreed that screeding was another way to go, but pointed out that in this case, the tiles should be removed first. I tried to do a bit of research, and I find much advice that it is indeed not a good thing to screed over any tiles or coverings and that the tiles should be lifted first. I can also believe that, if only underlay and LVTs are on them, it could be fine. After all - our carpet is lying on the tiles now, and nobody said that was a bad thing. Any opinion on this information I received will be helpful, as well as any opinions on whether we should have the thermoplastic tiles removed either way, because of their possible asbestos content. Thanks! Fiona
If you are having 'stick down' lvt then get the old tiles removed before doing the necessary checks to whether you'll need a damp proofing before the screeding process.
It’s more important that the floor is flat and dry. That’s what they should be testing for Sent from my iPhone using Tapatalk
Thank you for your replies! The advice about damp is good, nobody has mentioned that so far. Does that mean it would be ok for "swimming" flooring to leave the tiles? Is there any way to know whether the thermoplastic is safe underneath the current carpet? What about screeding - is that a no-no then?
