Thanks, t-keela.
It is on a slab. My father also in-law recommended a scraper and sander, which seemed like a great idea until the asbestos issue came up. If it turns out that I don’t have to worry about that, this will be the way we go.
Otherwise, I have no idea how to get the floor up. Leaving it in is not an option, as it won’t be level with the slab where the carpet used to be.
I’m wondering if I can just peel as much vinyl up w/ my hands as possible, leaving the backing and the adhesive on the floor, put the vapor barrier over the whole thing, and then the Pergo. Since I won’t be grinding the material, I prob won’t have to worry about the asbestos… or should I?
