Hi all,

Thanks for your really helpful advice which I will pass on to my tiler in the morning.
In fact I'll just send him a link to this thread I think.

I'll let you know how it turns out but I strongly suspect it'll involve trashing about 25sqm of beautiful jurassic limestone.

Thanks again.

These sort of jobs really annoy me!! The customer spends a fortune on the tiles and then a so called unknowledgeable tiler comes along and makes a complete hash! Went out to an estimate last week where the customer had bought Fired Earth tiles (very expensive) and it's a mess and I felt so sorry for the guy. If you don't know what you're doing, don't do it!!

In 21yrs of tiling I have never use grey adhesive on any natural stone tiles. The limestone needs to be removed. Where there is no adhesive under the stone, this is were the tiles will be weak and start to break. Dont take no for an answer these have to be removed.

jburnett i am so sorry this has happed to you. unfortunately for the tiler he has made a catalog of errors and a trail to follow.
1. Tile on tile is never a good thing to do and in this case it has stopped the moisture from the adhesive going anywhere but up.
2. Grey adhesive and light porous stone is not the smartest move especially given the tile on tile.
3. sealing the tiles trapped the moisture in the tile.
4. dot and dab fixing is not a recognized method of fixing and a tiler that uses this method is ether to thick to know better or is using it to get over an uneven sub-straight instead of doing the correct preparation.

Whatever you do, don't allow them to re tile on top of whats already there!

Seriously though, I'm lost for words, its just disgraceful.

I recently made a mistake with a floor (won't go into detail) and the customer had reason to ring up to 'report an issue'.
I admitted straight away it was my fault and went back and sorted it at the first available date.

It cost me 3 days unpaid work and about £100 worth of materials but I walked away with a clean conscience and learnt a valuable lesson.

Also my reputation remained intact.
