Can I put new ceramic tile over old ceramic tile on a bathroom floor that
is concrete underneath the old tile
Actually,if there is no problem with the existing cermaic
tile,and it is down securily,you CAN actually tile right over. I would
suggest using a sealer & adheive remover on it first to remove any
existing residue.
It is not nescessary or reccomended to lay wire lath or hardi backer OVER
ceramic tile & certainly dont start screwing anything thru the existing ceramic as that will loosen its existing bond. You need only use a proper latex modified thinset preferrably Tec SuperFlex by HB Fuller, Or Mapei is Ultracontact or their Kerabond/Keralastic system. Keep in bond you are adhering the new tile to the existing tile,if the first installation lets go,the second one will be coming with it. You will also be adding height to the existing floor. Hope I didnt confuse you more,and you find this info useful. Good Luck. bellzie.
as a contractor, i would tell u that no! the odds of a problem
r 2 high..if the lower tile were to release u have a bust floor..then
theres moisture problems...take it out!

Never a good idea. The old tiles have a glaze which would not
allow for a good bond of the new tiles. If you are bothered by the huge
task of removing all the old tiles with a hand chisel I would suggest you
hire a small electric jackhammer, choose an appropriate time so as not to
annoy others with the noise and just go to it. This expedites the job
quite well.
Then you lay the new tiles on a sound footing. Happy tiling!
not recommended.it would be better to take off the old tile
.you will have problems
fitting doors,fixtures etc
This depends upon whether the original tile is secured well.
If the original floor tile is well secured, then you should be able to lay
floor tile on top of it. You must use a high quality polymer-modified
thin-set mortar for adhesion. In this case you might consider laying
chicken-wire first to ensure a strong yet flexible bond.
If the tile is loose, but you dont want to remove it all, try laying 1/4'' HardiBacker tile backerboard in mortar over the old tile using tapcon phillips style bugle-head screws every 8 sq. inches. Lay the tile over that. If you follow these instructions, ur new tile will be super-solid & ultra-strong.
THAT WOULD NOT BE A GOOD IDEA. GET A SLEDGE HAMMER AN GET TO
WORK ON IT.
It can be done, but it is never a good idea. Better remove the
old tile with a chisel, then install the new. You will get a much better
bond.
