Hi,
Planning to install tile over the existing tile on my bathroom floor. Theres' a few issues I'm looking for some advice about.
1) The existing tile is in good condition and on top of a concrete floor. The spot where I took out an old cabinet was never tiled and just has the concrete floor exposed. Should I fill this spot with extra thick tile adhesive to make the new tile layer level? Or should I rip out the whole floor of existing tile and lay the new tile on the level concrete floor (a lot more work).
2) If I decide to lay the tile over tile, how should I prepare the surface for max adhesion? I think the existing tile is ceramic. It also has a shine to it.
3) If I install the tile over tile there will be a higher lip at the door threshold. What can I do to to avoid tripping when coming through the door. I have carpeting outside the door that will be replaced. Should I make a gradual raise on the floor outside the doorway to minimize the hieght difference from one room to the other?
Any advice would be much appreciated.:confused:
Thanks,
Lisa

if you have a concrete subbase and tile over it consider;
the shine on the tile is a glaze. although you can use adheasives - i would say to go through the extra work and crack, pry, and clean concrete and start over new. in the long run you will not usually need to build up floors outside to match, especially if new tiles arre dimensionally identical to originals.also this eliminates tripping, toe stubbing, cuts from edges that in tile work can be razor sharp...the work done to remove older tiles will be a time saver in the finished project as well as adaptions to other areas to accomodate the higher flooring,( cutting door bottoms, transistion strips etc... also the glaze on the older tiles can affect adheasive capabilities. use a floor leveler where neded and make sure the sub floor is clean!!

No reason to over complicate things. It's perfecly acceptable to place new tile over old. For your low spot skim it even with the existing tile and let it set before you actually lay the new. You don't want to try to set tile in superthick thinset. Also make sure you use a high quality latex modified thinset like Tec Full flex. As for the transition I use an oak beveled threshold that makes for an easy walk over the transition without tripping. Goodluck!
