Ok, sorry, had things to do this evening, back now.
I am most grateful for your replies, I hope you're not all in bed yet.
Right, I have been using this forum for answers to my questions on this job, and yes I can confirm the old plasterwork was removed back to bare brick, I did it myself with a friend.
New plasterboard was then affixed to all the walls. To get the story right...
The plasterboard was originally fixed to the walls by a plasterer who obviously wanted to get the job done quickly, the tiler came the next day and started to tile using the "correct" method, covering the wall with adhesive, then using the notched trowel, then placing the tile, however, as he was going along the weight of the tile was pulling the plasterboard from the walls.
He stopped and said he would not continue until it was corrected.
The Plasterer came back and re-affixed the plasterboard much more securely.
Time had passed and the original booked tiler was then on another pre-booked job, so the contractor sourced another tiler who started on Tuesday this week.
It was not until today I noticed that he had been fitting the tiles using the method shown in the photo on page 1, dot and dab.
I think there is probably 50% - 60% of the tile covered in adhesive, I am sure the tile in the photo was "for show" and the ones that no-one has seen will have less on them.
Once I noticed this, I asked if he had done the whole room like this and he openly admitted that he had.
The tiler and the contractor are both saying it is fine and how they were told by the adhesive company and a tile firm that this was how it should be done.
I am now obviously a bit stuck, I paid £1000 ish for the Tiles and have paid this contractor to basically rip out the whole room, fit the tiles then fit a bathroom suite & shower cubicle with all ancillary works, it is going to cost him upwards of £3000 to rip it off and start again, perhaps more.
Obviously he is not going to "want" to do this.
