tilling over tiles why not

[The Legend; Phil Hobson RIP]

Ray I think you are missing the point mate, no disrespect to you, or any other poster on this thread. Gary and others summed it for me. The question was never will tile bond to tile, as you say many well known adhesive manufacturers have products that will adhere to a tiled surface.

The question is, how well are the tiles bonded that you are tiling to? also who fixed them? what adhesive did they use? what was the original substrate? the questions never end.

Why not strip the old tiles, see what the substrate is, and does it require any prep work? we are no longer fixing 150mmx150mm tiles, more likely 600mm x 300mm or larger. I have been a professional wall and floor tiler man and boy (44yrs) and have seen and heard it all.

Lets try and give good advice on this fine forum, or just not bother posting.:smilewinkgrin:

The adhesive manufacturers will only guarantee that the adhesive will stick the new tile to the old....They will not and they can not state that the original tiles are sound enough to take the weight of the new tile.
A recent conversation with a well known tile company stated to be that a plaster skimmed wall was fine to be tiled with tiles weighing 70kgs per m2.....what they really were saying was that the adhesive they would supply would stick the tile to the plaster........whether the plaster de bonded due to the weight was of no concern to them and nothing to do with them. That was a matter to take up with the plaster company.

for good advice to be heard bad advice has to be talked about:yikes:

Even Bal technical services have recommended not to tile onto tile. As above you have no idea how well the tiles are bonded and even if you test a few how are you sure you havnt just tested the only good tiles? You would need to test all of them to be sure.
