Floating Installation This method the floor floats over foam cushioned padding.
Absolutely, but you have to be aware that it will raise your floor level and you might have a problem with door jambs and levels of flooring from one from room to another.
Absolutely.
If it sits over a cement floor, then no. If it is a nailed down floor, then you can, but you still have to install a cement board.
Yes, you can install a laminate floor system over existing hardwood floors. Just be sure that the existing hardwood is pretty smooth or the hump in the floor will transfer through. You must use a vapor barrier over your existing hardwood to reduce sound as well as moister transfere between two floor systems. Be sure to let your new floor acclimate to your room temp. for at least 48 hrs. this is especially important if you are installing floor in the winter.
yes, but it will slide over the years so I would not
of corse you can! it's not common practice but if your floor is sound it should be fine
Yes, it must be a glue down wood or a floating wood floor.
Tile is an insulator. If the tile is placed correctly over an existing wood floor and is sealed with grout, it will insulate the room it is in.
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.
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
This process can be done but it is involved and will take some time. First, clean the existing floor. Then lay down and secure a moisture barrier. Then you can install the flooring. However, prior to laying out the floor make sure that you allow the laminate flooring to acclimate to the climate of the house to ensure that it takes well.
Usually, but when the installers place the pad down, often they used staples. Also, in time the pad wants to stick to the wood.
