I personally would take up all the old tiles and start over, it is more work but the most appropriate action. If you really don't want to take up the tile there are some things you have got to take into account. Is the old tile still down good? If not, you just need to pull it up. If the tile you are talking about is in a kitchen, does the tile go under or up to a dishwasher? You don't want to lay the new tile down on top of the old and have your dishwasher go bad in 3 months and have to tear up the floor to replace it. Is laying tile over the existing going to cause issues with your door heights? If you do decided you can lay the tile over the old tile I would suggest two products to put over the old tile to insure a good bond. Pro-red, or red guard. They are actually the same product made by the same manufacture, but red-guard is package for home depot and Lowe's. It is a pink material used by tile layers to ensure a good bond when they are unsure about were they are laying the tile. Another thing it does is help to make sure cracks don't repair into the new surface. It is just a insurance policy that works good. For the guy who did is shower, pro-red would have been highly recommended because it is also used by those who build water features, to make sure that if water does get through their product, it won't make it past the pr-red membrane they put down. Good Luck

Ceramic tile is not only pourous it has a glaze coating. Your friend is right, glueing new tile over old it not a good idea. The new tiles won't stick to the old and the grout will crack. It might be a 50 year old house, but don't you want to do a proper job? Taking old tile off it not hard and will look way better.

I would not recomend trying that. You will be picking up tiles within 6 months and doing it again. Just did one job, the contractor did that 4 months ago. Now I have to lift it all down to the floor. The original tiles were contact cemented to vinyl. Do it right and enjoy a quality finished product.

It's actually best to remove the old tiles but if you really don't want to you can lay a base board and attach it over the old. You will then have a clean base on which to lay the new tiles.

well,some interesting advice,listen carefully,if there is any size to the area check the strength of your floor first,ceramic tile is heavy and strains floor joists,no matter what anyone says,if you do this like you want,the floor must be strong enough to hold two layers,the old tile must be 100% fast and tight,you're taking quite a risk no matter what anyone says and it's alot of money to waste if it fails.

Yes you can do that - no problem at all - I even did it over glossy tiles in the shower with no problem at all. after 5 years they are showing no signs at all of moving and definitely not coming off - just make sure you wash the previous tiles thoroughly to remove any grease or soap etc. first.

yes perfectly possible to tile over tiles, don't even think you need anything special to do it... the only reason not to would be if any of the tiles were already loose...
