whats the problem ? ete

problem is that a vast ammount of the tiles have blown....spoke to builder and he assures me the under floor heating wasnt whacked up to full and was gradually turned up(well thats what he has told me i cant proove this)......i have never had a problem before.....so if he is telling the truth the only other thing is the adhesive.........have mentioned it in shop i get most of my materials from and they refuse to stock it as they have had complaints....rang BAL they deny any knowledge of problems.....bottom line is that i could go bust over this......cheers ofr reply pete

Seems like a job for the PST from Dunlop then.

I have never used dunlop adhesives, and with stories like this I don't know whether I should or not. Is this just an isolated case?

I use this quite a bit doing limestone and marble. Had a failure with it, did the job about 2 years ago onto existing ceramic tiles. Had to go back a few weeks ago to change a few of the porcelain I laid as they had smashed. Took up the tiles and the adhesive just crumbled in my hands, fell off of the back of the tiles and lifted straight off the floor. I sent samples away to BAL to be tested, but haven't heard back yet. If you get no joy with them go to Ceram research. There is an inherant problem in trying to mix white adhesive at the factory, lost count of times I had to throw not only bags but pallets away due to the mix being wrong and the stuff going off as fast as you could mix it.

cheers i am going to have to get the NTA involved and see if they can help....fanx for reply

whats the size of the floor ?

floor is about 106m2......600x600 porcelain.......the client is a total mare so alot of cost will involve kitchen being taken out as he is not likely to allow me to chop back to kickboards..same goes for all skirtings/architraves....this is the whole of ground floor bar 3 rooms...i was trying to do the right thing by the actual builder who provides a good 60-70% of my work...all large prestigious luxury homes.....but now i have realised this could cost me my business i no longer see why i should take the blame.......if it is a fixing problem i will hold my hands up....but as never had this happend like this before i dont understand.

Not telling you how to suck eggs here...but did you leave perimeter joints and expansion joints within the project...?

Also what depth of bed did you apply....?
