Re: Tiling on tiles

It is possible to lay floor tiles on existing floor tiles but is unwise. The reason is you have to rely on what has been laid before and if you are unsure how well the original tiles are laid i would stay well clear and relay the floor yourself, at least then you can be assured that what you have laid will be correct and sound.

What about if I am sure that the existing floor is OK?

Re: Tiling on tiles

It is perfectly possible and it is done often, but you have to be SURE that you are tiling onto solid substrate.

You would need to give details of what the existing tiles are fixed to for us to give more precise details about adhesives and grouts etc.

Re: Tiling on tiles

If you are sure the existing floor is ok, make sure the floor is really clean and free from all grease and dirt and all tiles are sound and not cracked..
You can use

MAKE SURE THE TYPE OF TILE(BACKGROUND) YOU ARE FIXING TO IS LISTED IN THE INSTRUCTIONS ABOVE.


and grout with

Hello mate,

I would do this the following way;

first remove any broken or loos tiles and fill place with a repairing compound.

clean floor and use degreaser to lift any old grease etc.

prime floor with a suitable primer for screeding over and screed with a self levelling compound.

you now have a flat surface to tile over

I normally try to use products from the one manufacturer as they always specify products that tie in together. e.g. primers, screeds and adhesives etc.

would anyone else do this similar? how would you do it?

hi mate,

this is not a problem! you can tile over existing tiles.

as an example of screed you could use??? Arditex by Ardex it is a powder/ latex liquid mix and would be suitable for screeding over existing tiles.

Thanks for your help 1 and all just to confirm - I need to screed over the existing ones first then lay the adhesive then the tile or can I just clean the old tiles lay the adhesive then the tile?????????????????????????

 

[tfs]

I would screed over first but you can just apply adhesive over tiles too providing that they are sound. You will need an adhesive that is suitable for tile to tile.

good luck

If these tiles are a glassy finish, then you will need a highly flexible adhesive to get a good bond.......wash the tiles down with a degreaser and clean with plenty clean water....You can use rapid setting adhesive with a flexible additive and mix according to the instructions, this is usually 1 to 1 with water........A flexible grout would be a good idea as well........
