Covering old vinyl Doing a kitchen remodel and have questions about the old flooring underneath. A little history that will help understand the layers found on the floor today... Not sure when the house was originally built but my dad bought it about it about 1967. I learned that it started out as a two story house and the second story was removed before we ever saw it (maybe a fire) and it had been remodeled before we acquired it. About mid 70s, my mom put down 12' square, sticky back flooring tiles. I ended up with the house and remodeled the kitchen about mid 90s. It was my first attempt at putting down sheet vinyl and I did not do enough research. I could not get the vinyl squares up so I covered them with 1/4" plywood. Then I used adhesive on the entire floor before putting the sheet vinyl down. It looked fine that night but next morning it had a large raised area in the middle. I tried to figure out what to do and I ended up cutting it, pressing it down and nailing the heck out of it. That why you will see nail heads in the picture. OK, it says "invalid image" when I tried to add a picture from my desktop so I'll just describe what I found, what I am seeing after removing a section about 3' x 5'. Top layer is the sheet vinyl and 1/4" plywood from mid 90s. I plan to remove all of these two and not disturb the rest because of the likelihood of asbestos.. Below that are the squares my mom put down, mid 70s. Below that are the vinyl(?) squares that were there when we moved in, mid 60s. Below that is a hardwood sub-floor with a black residue on most of it. So, I'm thinking that maybe I should remove the sheet vinyl and plywood, then cover it with some kind of self leveling compound, perhaps something that will have a little flexibility after it cures, just in case there is any movement in the floor. By the way, the new flooring I bought is Smartcore premium engineered vinyl strips that look like wood (Cottage Oak). There are a lot of self leveling compounds at varying costs. I'm hoping for advice on what I can apply over the remaining two old tile types, making it all level and not be concerned about the compound cracking if there is any movement in the old sub-floor/ tile. Thanks.
