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?

 

[Perry]

whats the size of the floor ?

 

[strummertime]

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.

 

[Gazzer]

Worrying times mate, i hope it all works out for you.

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....?

 

[Gazzer]

And what type of screed was it?

 

[P'boro tiler]

im sure its an adhesive failure. take a step back and think about it. youve never had a failure. if you did do something wrong (like poor fixing technique) then it would of only affected a few tiles! im sure its not your fault!
also, i tiled a 16m2 floor with grey dunlop set fast flexi and had to replace one tile due to not noticing a scratch. when i removed it i found it hadnt bonded to the tile well and crumbled off. i mixed it up plenty wet enough and had 100% coverage (till it crumbled off). ive never had this problem before and thank god i learnt the stuffs poor quality on a small job!!!
i pretty much only use mapei stuff now

yes dave i did ...the tiles where fixed to a 12mm bed.....incidently i have since been back to project to change some tiles before client moved in ..and tiles i replaced with different adhesives are sound as a pound

 

[Sully]

You rang BAL and 'they deny any knowledge of problems'. I would have thought as a matter of course they would at least test a sample or send out one of their technicians on site? Did you not request this?

As for the underfloor heating / screed substrate. I'd be taking a closer look at these elements too. I think you need an on site visit and should insist on one.

As for the other failure mentioned - tile on tile. I'd personally only use a two part on the rare occassion that I'd be comfortable doing tile on tile. Any SPF is a risk in this situation - my opinion anyway.

:hurray::hurray::hurray::hurray:

Now THAT's what a good forum's about.

I would really like to hear the outcome of this.:yes::yes:

 

[BDS]

Me too...

 

[mart1]

I'll bet you a pound now it's the underfloor heating ( and i do mean certain criteria wasn't followed ). this is a age old problem that will continue to happen and there is nothing that anyone can do to prove otherwise. only option is to lay blame with the fixing or adhesive because there aint owt else. It certainly is not a fixing problem and that is common sense to anyone surely.

Didn't get your call strummer.
