No, you should not.
No, you can't. It would peel off like sunburned skin, if it ever even set up. And why in the world would you want to do that anyway? Yes you can; http://www.nauticexpo.com/prod/polyflor-voyager-flooring/vinyl-floor-coverings-for-ship-31432-193520.html
It is possible, but it's not the best practice. If you can easily remove the existing vinyl, then do so. If the vinyl won't peel up, then you should consider two possibilities: Remove the vinyl along with the wood underlayment (or scrape it off if your subfloor is concrete), or install new wood underlayment on top of the existing vinyl.A third possibility is this: If the existing vinyl is securely glued to the floor, you could apply an embossing leveler (cement-based product) in a very thin skim coat over the vinyl. This seals in any stains, levels the floor, and gives the new vinyl a nice, smooth surface to lay over (or a good surface for vinyl glue to adhere to).Most flooring manufacturers will not honor the warranty on their vinyl if it is installed over existing vinyl, unless you do the embossing leveler step above.
What is the weight of Vinyl Floor tiles per m2
Most vinyl flooring comes with finishes from matte to high gloss and do not need any additional treatment. There are products like "no wax waxes" that can add luster to a vinyl floor, but are not impenetrable. I think that because vinyl is a soft flooring material that is easily dented and cut, any substance used to create a hard glossy finish might crack and peel.
Vinyl floor covering.
The easiest vinyl floor tiles to install are the type called "peel and stick" tiles. These tiles come pre-cut so there is less measuring and little cutting. The backing peels off and the tiles can then be placed on the floor.
You might want to check the manufacturer's labels which often state whether you can use a product on a vinyl floor. You can use SC Johnson Wax Tile and Vinyl Floor Cleaner and Pledge Tile and Vinyl Floor Cleaner.
I believe these are just different names for cheap vinyl floor tile where you pull off a sheet of shiny paper to expose the adhesive.
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.
If the vinyl is down tight , the answer is YES, Laminate con go over it
