it's perfectly fine. even area rugs!
Carpet is difficult to install yourself if you don't have experience. For best results, rent a carpet stretcher from an equipment rental store. For easier carpet installation, consider carpet tiles. These are squares of carpet with an adhesive back. Simply peel off the backing to expose the adhesive and place the tile on the floor. Carpet tiles can be installed over vinyl, wood or concrete. Special carpet tiles can be used outdoors on patios or sun rooms.
If the vinyl is down tight , the answer is YES, Laminate con go over it
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.
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.
only if its solid wood under and a well stuck down single layer if there is any movement ie cracks in the vinyl the wood floor is not stable and a 1/2 ply should be laid down first then rosin or felt paper
Yes. The vinyl has to be specially cleaned and treated in order for the adhesive to stick. Special products and instructions are available at most home improvement stores.
yes you van
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.
Yes you can.
Yes, no problem.
Only if the vinyl was previously installed over concrete, and has a positive bond. Scar the finish of the vinyl with a hand sander (course paper), and use a high strength thinset for the installation.
Usually, but when the installers place the pad down, often they used staples. Also, in time the pad wants to stick to the wood.
