Can new floor tiles(ceramic) be placed over old ceramic tiles ? if so how do you go about it?

Answer 1

I am a Technical Sales Manager for a tile and stone setting materials company.

The answer to your question is "yes".

But the cavaet, as others have stated before me, is the condition of the old floor. If it is free of cracking tile or grout joints, then you have a surface suitable to tile over. You need only make sure the old tile is free of any bondbreakers, such as grease or oils, or sealants.

Once your surface is clean and dry, you are set to go. But I must disagree with previous responders who recommended Mastic (tile adhesive) or PVA glue. These WILL re-emulsify if subjected to moisture, and your new tile will start to lose its bond.

Instead, opt for a latex-modified thinset. The pull strength can't be beat, it never re-emulsifies and most contain an anti-microbial agent.

Your grout should also be latex-modified, for the same reasons.

Good luck!

Answer 2

In the world of remodeling, with enough care and preparation almost anything can be done. The correct question ought to be is it a good idea. The answer to that is no, I would not recommend it. I suspect the source of your question is to avoid the effort and labor required to pull up the old ceramic.
If you do not, you risk the inherent flaws of the first layer telegraphing up to the new floor and cracking tiles. This will happen I garrantee it. Debonding is a risk, no matter what ahesive you use. The more agressive epoxy bonding agents will have fumes that will make you house unliviable for up to a week as they off-gas and will kill any pets you may have. If you put down 1/2" plywood underlayment with the 3/8 tile thickness, your floor level transitions will be a challenge at the perimeter. Some food for thought

Answer 3

Yes, you can. You need to add a special kind of bonding chemical to the cement so that it will stick and hold firmly in place on the old floor tiles. (sorry, I cannot offhand tell you what the name of the bonding chemical is but it can be bought from a hardware store that specialises in tiles.)

Answer 4

Yes you can as long as the old floor is sound. Think about what effect this will have where the floor meets the skirting or kitchen units & plinth line, and the gap under any doors leading into the kitchen?

Answer 5

Preferably not. Take the old tiles off first. OR... glue a mat to th floor first, then stick the new tiles.

Answer 6

Yes, as long as the old tiles are in good solid condition. Put down your mastic and lay them as normal.

Answer 7

YES.seal the existing floor with a solution of one part p.v.a.glue to five parts clean water.allow to dry overnight,then fit new tiles.Please check clearance of doors.
HAVE FUN.

Answer 8

yes, will be fine...just lay over the old ones
