Redo my basement floor?

There are several self leveling, pourable masonry products that are available, however I don't know of any that will work if you don't remove ALL the tile. There are also several trowel applied floor levelers that you can apply in the areas where you remove tile. At best, unless you have experience working with any of these products, you would probably be wasting your time and money. They are difficult to use for the inexperienced and the end result is usually disastrous. Your best alternative would be to remove all of the floor tile and remove the adhesive residue to the point that you have a relatively smooth surface. At that point, you can install you floating floor. Be sure to install the layer of underlayment that's recommended for you choice of floor. If you feel relatively certain that you floor tile contains asbestos, it can generally be safely removed using an ice scraper, but don't go crazy and disintegrate the tile allowing millions of particles to become airborne. For any tile that is adhered really well, a little heat from a paint remover or a good hot hair dryer will usually soften the tile and the glue . Worst case scenario, heat using a propane torch, being careful not to burn the tile.

peel and stick vinyl tiles may be the least complicated. they arrive in 1ft by using 1ft squares and you the two glue them down or you peel the paper backing off of them and that they are self-adhesive. because of the fact they are in 1x1 ft squares it is going to likely be hassle-free to handle the ordinary shape of the room in view which you are able to decrease them to in positive condition and that they are small and hassle-free to handle. you may get them at HomeDepot, Lowes, and so on. they're going to help you out. they are probalby the main inexpensive issues too.
