Hi, I am going to rip out the 55 years old linoleum vinyl sheet in the basement rooms. I think there will be challenge to remove the dried glue left on the concrete slab. I think, I will try to scrape it out as much as I can and I will use self leveling compound over it. Is that OK with this method? and will it kill the mold.? The previous owner told me the water tank busted once and maybe still damp and mold under the sheet. I didn't pull the vinyl sheet up yet. My second option is to rent a concrete floor grinding machine and grind the glue off. I don't know if it will be dusty? I need to prepare the flat concrete floor to lay engineered wood floor on top. Thanks.
