Help please - tiles falling off wall!!

[CJ]

Soak a tile in a bucket of warm water......I bet the addy will scrape off no problem.

For me is it one of 2 options... primed with pva and also the plaster has not cured... you can see pigment on the back of that tile which indicates plaster drying out and lack of primer...

Also i would be worried about the bed depth of the adhesive... if you want my opinion it is fixer error..

If the plaster is going dark when you wet it there is no primer on the wall and if there is no primer the cement based adhesive will not stick to the gypsum plaster so it is the builders problem ask him to provide a method statement detailing every step of the installation. The adhesive company's do not lay down for people like this they will probably want to test the adhesive and they will know if there is a primer present. I think the builder will have to take this one on the chin as the fixing method is wrong and the thickness of the bed looks like it exeads the recommended thickness.

thanks everyone for your advice. I'll contact Larsen and the builder again. I'll let you know how I get on.

As soon as I saw the big dollops...and him dishing the adhesive tells me he's not a tiler! Builder primed with Pva I bet....it get em back to do a proper job..if not small claims court if I was you

I bet the builder primed with PVA.

Yes, thought the same. In any case, dot and dab is bad practice and just not acceptable.

Not only poor priming but it looks to me as if he's used rapid addy and not done the job quick enough so it's too dry by the time he got to these tiles so he couldn't get a good bond to the wall and the addy wouldn't flow to give the correct bed thickness. Rubbish work !

 

[Dougs Third Go]

no primer imo, very poor workmanship

 

[area tiling]

Theirs a few factors here that have lead to the failure , dot and dab anywhere is a no no for me, plus the bed of addy looks really heavy , didn't the tiler trowel the wall with adhesive first!
In Northern Ireland we work with quite alot of Larsen materials, you'll know If he used the correct manufacturers primer for the job, as it will have left a pink residue on the walls ! Am not saying that Larsen is a fantastic product because you couldn't compare it with the likes of mapei, bal , weber , Dunlop or bostik ! But if prepared right then you shouldn't have any problems!
Get the tiler and builder back again !

Thanks again all for taking the time to respond to my post - much appreciated. i have a small update as I had contacted our tile shop on Monday and the Larsen rep called me this morning - he came to our house and has taken a tile sample and photos to take back to their lab. Must say I am very impressed with him for taking the time to deal with us (and our tile shop too), and so quickly too. Will let you know how we get on.... thx This is not the only problem we've had with our renovation/extension but that is for another website forum and another day...
