Help please - tiles falling off wall!!

[shellshock]

Hello, I would be really grateful for your views and advice please.

We had en-suite and bathroom tiled during a major renovation job at the end of last year. We recently noticed that the tiles in both rooms appear to be loose so removed a couple from the bathroom wall. Well I say 'removed' in that once we had cut through the grout the tile came away in our hands.

I have attached some photos so that you can see. The adhesive is firmly fixed to the tile and there is none on the wall. The tiler used Larsen flexible adhesive which i supplied, simply because that's what our tile stockist carried. The builder is saying that the walls were primed and the tiler says he had never used Larsen before and has subsequently found out it is "cheap rubbish" - his words not mine.




Does anyone have any view on what might have gone wrong?

Thanks for reading.

primed with what and its a case of dot and dab again...big dots this time.

looks like It could be cement based adhesive and no primer but it is not a good installation

Thanks for your replies. I don't know what primer was used but the builder has insisted the wall was 'primed'. The adhesive was Larsen Flexible Fast set.

Did the walls have paint on before tiling?

 

[Diamond Pool Finishers]

Yes looks like tile over painted wall !

Tut tut tut. Imagine they fell off a landed on your head. He would be serving a lengthy jail sentence

 

[Mr T]

was it a tiler or a builder?

Hi all, thanks very much for replies. I'm pretty sure the wall where we removed the tile was newly plastered (definitely not more than 2 weeks before, and most probably less) - not sure about the other walls. I don't know what primer was used, only that the builder is blaming the adhesive which was Larsen Flexible Fast Set. I saw on the packet that dot and dab isn't recommended, but does this method often cause problems? Yes, very glad that my 2 year old daughter didn't have a tile land on her head...

Thx all.

ps sorry about photos, are they really BIG?! i'm a newbie and a techno-phobe!

Tiling too soon after plastering !!!

Sorry to see that.Dot & dab,plaster not dryed before tiling? possibly no primer ? the tiles look way off the wall ! Wet your finger,press it onto the wall where there was no addy,if the moisture goes into the plaster quickly it proberbly wasnt primed correctly. Id be worried about the rest of the tiles aswell.

I bet the builder primed with PVA.

 

[Mr T]

it was either primed with something or worst not at all and there is I coat of dust on the plaster I cant tell what it is tho.

Definatly no primer. Dusty surface, tiled too soon after plastering.
