Yes, you can use wax.
Not directly as the ceramic tiles will soon show through the vinyl flooring. If the ceramics are laid on a wooden floor, you must take up the tiles and overboard with 6mm plywood. If the tiles are on a concrete floor, you can leave them down and lay a latex screed on top to provide you with a smooth floor for your vinyl
The glue used to stick them to the floor is weak, or there was dirt or foreign matter under the tile, or the under floor was not completely clean when it was laid.
I wouldn't do it. Tar paper between subfloor and finish floor is a good technique, but gluing tiles directly to a tar paper surface is not a good idea.
It seems to have been discontinued...and if you pull it up, BE CAREFUL! The majority of nine-inch floor tile contains asbestos, and so does the glue it was installed with.
There are many glues specifically for Vinyl tile in hardware and lumber stores.
If it has a timber floor under and vinyl is solid to the floor and not to thick screw down 10 mm ply at 150mm centres. seal ply with pva sealer prior too tilling. If it is a concrete floor it is best to lift vinyl.
you cant
Yes, asbestos mastic (glue) under the tiles. ceiling or floor tiles?
Yes. In some but not in all. It is also found in the glue that hold the tiles to the floor.
Usually. Most peel-and-stick vinyl tiles have a decent glue and will adhere to a clean and relatively smooth subfloor. Make sure it is not OSB or particle board subfloor as peel and stick will not adhere I would recommend priming the subfloor with an oil-based primer first. If it is plywood, make sure it hasn't delaminated. Vacuum the subfloor thoroughly first. Paint and glue don't like dust.
A high-quality, flexible adhesive specifically designed for floor tiles is recommended for installation.
Oh, dude, of course there's vinyl flooring that doesn't need glue! It's called "peel and stick" vinyl flooring. You literally just peel off the backing and stick it down. It's like a giant sticker for your floor. So, yeah, you can have vinyl without the messy glue.
