    It is not recommended to do this, as unless the old flooring is level, and unless the new tiles lay exactly on top of the old floor tiles, they will not set evenly, and not wear evenly. This will result in cracking, breaking, and you will have a huge double layer mess that will have to be removed.


    Another major consideration is that the "new" floor will then be twice as thick- read- twice as high as the old floor was. How might this affect the reinstallation of any floor vents, baseboards, doors, lower cabinet doors opening,? etc.


    It will be extremely difficult to finish off the transition areas properly and to a degree that they are durable, safe, and do not cause tripping.

    You can by using the proper adhesive but it's pretty chancy. It would probably work out better to break up the old tile, remove all of the debris, then resurface the floor with a self levelling product made for that purpose. Mcquaig r you place a floor over a floor, you will have to raise all of the moldings and return all doors and match up adjoining floors??

    I wouldn't recommend this. Chances are the old tile will eventually loosen up and cause problems. In addition, you would probably not get very good adhesion to the tile like you would if it was gone.

    That would depend on the flooring. The best is to remove loose flooring. Level the floor and then lay. If it's a kitchen, bath or laundry, you need cement board under your flooring.

    If the old flooring is stable and flat with no loose tiles it can be done but consider the new floor will be about a half inch higher with a step you could keep tripping on as you enter the room. A large local shopping mall retiled the entire mall by tiling over acres of tile, so it is certainly possible. However if the old tiles are a non-porous glossy finish, they may need to be "roughed up" with a diamond surface grinder to allow proper adhesion of the new tile ciment. That alone is a messy dusty job so it might be just as easy to remove the old tiles. A tile over tile job is usually only done if it is a very large area to save on removal and disposal costs of the old tiles. If it is just a small area, it's usually best to remove the old tiles.
