Subfloor for laminate vinyl tiles

[ar87]

Hi,

We are replacing the floor covering in our conservatory and have chosen some LVT from a local store. We currently have amtico down from the previous owners but it is horribly scratched and has lifted in multiple places. I took up what I could before the flooring store sent someone round to check the floor, but it was very difficult to get much up as it is well glued down. From what I did lift, it seems we have a plyboard floor underneath but patches of glue are proving difficult to scrape off, and in a few places some of the wood has come up with the amtico too, so there are splintery lower patches.

The guy that came round suggested re-plying the floor (which they can do at a cost) but we would need to take up what is there now and see what's underneath (he thinks chipboard). As you can probably tell from my description above I am not a professional! Firstly I wouldn't know where to start with taking up what's there now and I am reluctant to tamper too much. My colleague said when he had one done, he levelled the floor with a compound rather than ripping it up and re-boarding. From the images I have attached, what would you recommend we should do?

Thanks

What I use to get it up is a hot air gun, like your blow dryer but on steroids. Easy smeasy. Then I would scrape old glue off and skimcoat with ARDEX SF

From what I'm seeing is there is luan under the Amtico. Easy enough to take up with a roofing shovel. But at the moment I would be more concerned with mold in the corner. That needs to be addressed before you do anything. You got a leak somewhere. And the black could be black mold without testing I don't know but the criteria is there.
