Tiling on tiles

[diamondtiling]

110mm square tiles? weigh one on a kitchen scales and times it by 90, that will give you a meterage weight, at least then you know what your putting on your walls, cement based adhesive is far better than tubbed.

110mm tiles...i am getting a feeling that these would be porcelain or vitrified so make sure adhesive is suitable

Just to add.. if the tiles are glass glazed as you say.. then dispersion adhesives will not bond.. you will need an S2 cement based adhesive..for direct bonding.

Ang to agree with comments above... pull them off and stat a fresh.

The tiles in question are fitted between the work top and cupboards in a kitchen, so We're talking about half a metre high all around and they all seem fairly sound. Do you think that weight will be an issue in this case? The old and new tiles are small and light weight.

Is there any other way of keying them properly other than using a sander (which I don't have)

i asked exactly the same question not a couple of weeks ago , i was all for overtiling as i felt the old tiles were sound , i changed my mind and pulled them off , how glad i was , the old tiles came off the wall with no more than a wallpaper scraper ..................

You usually find that everyone will say that "the tiles are still on the wall so are fine" The truth is as soon as you release tension by removing one tile, the others soon follow.

Only on friday did a client say to be that the tiles on the head of the window reveal were sound and didnt want to remove them for fear of further damage. i inserted a trowel into a slight gap i coould see and they all came away. His face was a picture of embarrassment and delight as the tiles didnt even break, came away in areas of up to 6 tiles (old 4" tiles) and then he saw the substrate was sound, so a quick coat of primer and we were away...total time 5 minutes max.
