Will napalm help get up vinyl floor?
Seriously! I am going to tile my floor, and although I understand you CAN go over the vinyl with a certain thinset, I figured it was better to get down to the concrete. Well.... I don't know if the homebuilder used some NASA-strength glue or what, but this is torture.
The top layer came off fairly easily, then I scraped a white layer off. Around the edges.... maybe a foot from the wall.... it is down to the glue and concrete. But the rest of the floor has this grey/cardboard-like layer that is really stuck.
1. Considering how stuck down this layer is.... any chance I could tile over it with a quality thinset? I made a couple calls, and one installer said it was no problem to go over it. Would something bad happen?
2. If this stuff really needs to come up..... are there any chemicals I can use? What is the best way to do this? I was working with a 4" hand scraper from Lowes, and barely got anywhere in like an hour. I don't want to spend 30 hours scraping up this floor.
