Hello Folks wiser than I!
So here's my deal:
I'm currently going for an install of luxury plank vinyl in a small bedroom of a very old house...the only thing is, my sub-floor is patchy and odd with original hardwood+a patch + random squares of linoleum in one corner, offset by a very strange/unique mosaic type old-ass tile pattern filling out the predominate space of the room. The spotty nature of the sub-floor is only offset by the fact that this house is OLD AS HECK and basically slopes/settles down an inch or at about 2 feet in from the front-facing wall. I've attached a picture for reference with a level.
My questions are thus:
1) It seems that the main issue is the slope at the front of the room, albeit a big problem. The rest of the room is fairly ok, but I'd feel a lot better if I could just get a nice flat substrate. I DO NOT want to remove these tiles as I have no idea as to whether or not there is asbestos in the mastic or the tiles themselves. So what are my options if I do not want to mess with these tiles?
Can I just throw 1/4 or 1/2" subfloor over the whole room? If so, how can I address any potential deflection? Is it possible to put self-leveling-compound underneath the subfloor?
I'm really at a loss for an idea here given that I'm just not sure how secure SLC would be in this instance, yet I don't want to remove these weird tiles. If there's anybody out there who might have some insight for me, I'd really appreciate it.
