Re: Removal of linoleum flooring for ceramic tiles
I can answer a few of those questions. The old vinyl can be removed with a vinyl stripping tool, either a manual or power operated. If you've got more than about a 10x10 area I'd recommend a combination of a manual knife sc****r and a power tool (talk with a rental yard ). Residual glue isn't a problem if your going to use mastic to glue down the new tile, however you'll need to clean the floor a little better if you're going to use Thinset (cement based "glue" ). Other than scraping the old glue up, I'm not sure what else could be used to clean the surface. No underlayment is necessary when tiling over a slab, however if there are any cracks, you're going to want to install an isolation barrier to keep those cracks from telegraphing through the tile.
