if the old floor is down good and tight, you can go right over it. If it has a strong embossed pattern it may telegraph through the new floor though. you can skim coat over that if you need to.

Can a cushion vinyl floor be laid over another cushion vinyl floor?

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.

How do you install vinyl sheet flooring?

Answer from Choices (http://www.choicesflooring.com.au/vinyl/) Generally, cushion vinyl is laid loosely so any imperfections in the floor don't show through over time. It can also be glued down, but the flooring needs to be completely level. Vinyl tiles or planks are glued down so the surface needs to be completely level, which is done by applying a self- leveler to the floor if required.

Do you need underlay to fit a vinyl floor?

no and it would probably be a bad idea as it is likely to move around. Vinyl is cushioned anyway so there would be no point. Underlay is put under carpet to stop the carpet being crushed. Vinyl will restore after being walked on. ------------------------------------------------------------------------------------------------ Answer 2: Underlayment is used on vinyl when installed over a wood substrate. Vinyl will take the shape of the floor below requiring a smooth surface for installation. Without this board, often a floor will telegraph the imperfections below. Additionally the underlayment should have the nail holes and seams between boards patched with a wood filler.
