Hello malc..

The best way is to remove them IMO...then you can make sure the wall is in good enough condition to accept the new installation...

Tiling on tiles has a few issues that need to be addressed before you can do it...so it is easier to start with a blank canvass...

[Malc006]

Thanks for your reply, will pass on.

Out of interest, what kind of issue would arise if you did tile over??

There a few issues malc..

1 : extra weight to the walls....there are weight limits

2 : You cannot guarantee how well the existing tiles are fixed and whether they will be solid enough to support the new installation.

3 : Certain tiles, like glazed ones need a different adhesive to adhere to them..

But the main issue is the weight one and how well or if they will support the new ones..

Although taking off the tiles and starting again is the prefered method, there are also issues with taking off tiles.

1 : When taking off tiles always be prepared to replaster/reboard the walls

2 : A hell of a lot of work and mess taking off tiles

3 : Continuing trips to the dump or cost and inconvinence of hiring a skip

4 : Not the ideal job for a novice in the building game

5 : Ache and pain for the next week

Ps.
on the plus side you will get a lot fitter and build up some muscles.

Just because there is work taking them off, that is not a reason to leave them on don't you agree...

Tiling on tiles is a DIY way around things....but in certain jobs it can't be avoided , i know that...but the propper way is to remove, make good and start afresh..

take a couple off to see how well stuck they are.sometimes they can be poorly put on in the first place and taking one off brings another 10 with it in this case definately take them off! if they are well stuck then i would tile over them.i have done this many times and have encountered no problems.I would recommend prepping the surface with almost neat pva and some sand for added grip.

Are you sure..?...

PVA...why..?

[swiftfix]

pva and sand slurry on to the old tiles.when dry gives good grip for the adhesive i have found.

[simhopper]

PVA and sand is used for plastering ontop of tiles but have never PVA when tiled

Thistle Bond it is what you should use for plastering,unsure if you could use it for tiling

Sorry Swiftfix but if you are going to do this SBR and sharp sand but with right addy not needed.

first of all it is better if you remove tiles before fixing and prep the walls if required and as for pva read the pva v primers ll the info is there

[swiftfix]

ok it is probably better to remove old tiles and replaster walls etc but if they are well stuck to the wall i see no problem in tiling over them.ive done it a few times and have had absolutely no problems or comeback.

,gonna have to disagree with all your post mate, for the extra cost of removing old tiles and adding the cost of a p/board on to the job, it's a deffo no brainer!! as for prepping with pva, ffs! man

plastered walls will only take 20kgm2,inc. adhesive, over that you run the risk of pulling skim off the boards, with the tiles,addy etc.best to leave boards/wall unskimmed!

I agree with you on this Doug,but it's like a thread thats running just now customers don't want to pay that bit extra for quality.You start telling a customer to rip down walls and re-board they think it's a big job,when in reality it's not.
