I am having a bathroom fitted out. The builders stripped the old tiles off the wall and put new tiles on the wall but the finish was very poor on two walls and they have agreed to re-do them but they have started tiling over the old tiles. Is this ok?
They are quite heavy, large porcelain tiles. The builders are insistent that it is perfectly fine to tile over tiles, especially as they are tiling over new tiles and because the two walls they are re-doing do not have any door or window frames but I have told them to stop work until I take some advice.
Can any tilers please help me with some of advice? Thanks!
it is possible but i will recommend to remove old tiles and prepare the area.
Post your job & get responses from local tradespeople. Read reviews before you decide to hire.
tiling over the tiles is fine. i would ask them to put a bonding agent over it first tho just to be safe.
No you can't put tiles over tiles in few month time tiles will come off,this is not normal practice.
Not really the best thing to do
I would advise taking them off and starting again,maybe with a different tiler who could produce a good finish 1st time
Yes you can tile over tiles but best to stagger the joints with the existing tiles that are tiled over to make the bond stronger
Hi, I think you did a right think to stop them in progress! Allowed to tile over on existing tiled surface but not on any circumstance! Need to consider about the receiver surface (brick or stud wall) The weight of the tiles, the type of adhesive and also very important would be the primer! I would recommend to use Eco Mape Grip from Mapei!
You need to Remove first old tile and repair the wall then put tile ,if you put new tile over the old tile It will be fAllen down after some time,,
Tiling over tile is usually a much easier and cheaper solution than pulling up your original tiles and re-tiling your floor or wall. One advantage of doing this is that it is time-saving. You do not have to allot work-hours to pull up the existing tiles which means the tiling work can be finished much faster and all without the big mess, so yes you certainly can, but before you do that, you should clean spotless your existing ceramic tiles. This step is very necessary and often overlooked. In fact, it is done not because it will look good but because any grease or dust will make it harder for the tile adhesive to bond.
In theory it is ok to tile over existing tiles, but it very much depends on the type of background wall and the weight of the tiles. Personally I would never tile over tiles as there are too many variables.
The existing tiles need to be sound and level and the weight needs to be accounted for. If it's a block or brick wall this will have a maximum weight holding capacity and if the wall was plastered before tiling then the tiles will only be stuck to the plaster and not the wall itself.
If the walls are plasterboard then this too has a maximum holding weight. So you need to find out the weight of your tiles per sm and check if this is ok with the type of wall the tiles are stuck to
Another factor is space, if people just tile over tiles then you end up loosing space all round and this can soon add up!
Hope this helps
It is not something I would advise but using the right adhesive it can be done
No no no they will not adhere and in time will fall off.
Take them off and start again.
Yes you can tile over tiles
Make sure they are using flexible adhesive and not the ready mixed bucket adhesive and that the rest of the bathroom was done with flexible adhesive
It is certainly not best practice. It can be done but it depends on what sort of wall you have, the type of covering (plaster, render, blocks, cement boards, ...) and importantly the weight of the tiles. personally if it was my bathroom, the existing tiles would come off.
It is plausible to tile over tiles, however the likelihood of them getting a better result than their previous one is minimal unless they either use more adhesive too level it out, which could result in longer drying time, more chance of them breaking when bumped into as more clear space between the tile and surface.
You can tile over tiles, with the right preparation, but I would never do this, the proper way is to strip right back to original wall finish.
Dont worry if you do pull a bit of plaster when stripping the tiles, as its easy enough to replace.
Tiling over tiles can make it awkward, ie extra thickness when tiling around shower fittings.
For the sake of a few hours work I would take them of.
Ideally I don't recommended it
Yes no problem but need put a special primer
We never tile over tile. some people do. Under regulations you must not bridge more than 32 kgs per meter in domestic house hold. If the tiles fail the hole wall will come off and have seen this happen in bathrooms that are not even 12 months old and the weight can do serious damage and harm.
you cant tile over tiles as its just bad practice, id take them off and make good walls then tile
This is ok as long as they use the correct adhesive
Yes provided they are well fixed the originals that is and enough room around doors and windows once new tiles on, use pva on existing tiles first. Can save a lot of work and mess.
It is fine to tile over tiles. The only proviso would be to make sure they use powder adhesive not ready mixed because the ready mixed is not strong enough for large porcelain tiles.
It is possible to tile over tiles with the right primer and as long add tree original tiles aren't loose. However with heavy porcelain tiles I would always remove the old tiles.
