I am working on putting in vinyl plank flooring in my basement. I ripped up the carpet and there are what looks to be 12"x12" Vinyl squares adhered to the concrete slab (i am moving forward assuming these are asbestos tile) Some were damaged and came up easily- i carefully removed those pieces spraying them with water to keep and dust minimal until i was left with only piece that were well adhered. I dont want to rip up the floor because of the cost and risk of asbestos going airborne so i was planning on leveling the floor and installing the plank directly over. I was going to use Henry patch and level to fill in any divots, cracks, or imperfection in the exposed concrete area and my plan was to use Henry Feather Finish to skim coat over the entire surface to level any missing tile and imperfections in the floor. My question is: does this seem a sufficient way to go about preparing the surface and if so, do i need to prepare the tile and specific way before applying the skim coat to ensure a proper bond?

Any help is greatly appreciated in advance, I have also attached some pictures.

9x9 tiles generally contained asbestos, so it is highly unlikely yours do. HOWEVER, it looks as if they were adhered with cutback cement, and it most likely does contain asbestos. You won't know unless you have it tested. You don't have to remove the tile, but you will need to float the depressed areas without tile using SLC (Self Leveling Compound). But applying LVP over it is no problem.

Actually many 12 x 12 tiles also contained asbestos.

With the cutback adhesive, then it is highly likely. Same resolution, SLC, then lay on top of it. Don't disturb it.

Neal,

I found the exact same website with the tile after i tore up the carpet so that was my justification in assuming it is asbestos. With that out of the way i am leaving all the intact and well adhered tile down and leveling...........does anyone know if i have to do anything to the tile prior to laying down skim coat over it or will is adhere?

30 years ago they sold a product, filler that you used to level out the vinyl floor before going over it. I don't know what it was but i would try what you have and see how well it is stuck when dry. Vinyl plank is pretty thick, not sure you need to fill the tile.

I agree with Neal. The thickness of your LVP won't telegraph as much as say roll linoleum would. That's when a skim coat is needed. You should be fine.
