Would you consider this quality work?

[Stustunz]

Take a pic from ceiling height so we can see at least 8 corners to see if there is size variation.
Those look like glazed porcelain or ceramic tiles not rectified porcelain.Often one corner will curl up or down when made with that type of tile.(pain the butt to get flat)and not been rectified means they are normally out of square also.
Put 2 tiles face to face and see if they rock or can see light.
Also measure on the diagonal each way to see if tiles are square.

If there's a 2mm gap at the skirting, up and down, then it may be bent tiles - not your Tilers fault!

agree with this, and a nice neat silicone bead will tidy it up nicely

Perhaps decorators chaulk as its paintable.

I'd be interested to see 2 joints in sequence next to each other in one photo, if the tiles are sized wrong then you can have 1 joint looking wrong and the next 1 looking right, still fixer should be oddsing out the differences, and you say they are are 80x 80 when you check them but how exact are you beong, I rarely find tiles are exactly 800 x 800 or 600 x 600 etc. Don't get me wrong there is some workmanship there that needs addressing but sometimes the tiles can dictate the level of quality that can be achievex. If that is the case he should certainly of spoken to about it right from the off and even more so because it's clear the level of quality you are expecting.

This is why i always use bigger spacers on floor tiles.

Hi everyone,

Thank you ever so much for the replys.

I now have a new issue. The tiles have started to sound a bit hollow and after our last issue I know that's bad. That started to happen last time and it just got worse and worse and is part of the reason we re-did the tiles before.

When we were getting the tiles up last time the tiler said he couldn't believe they came up clean. Virtually no adhesive stuck to the tiles at all which he said was very unusual.

This time he squeezed the tiles down a load to make sure the adhesive would stick to them.

I've just taken one up and again to see what's going on this time and there is no adhesive on the tile. It's stuck to the floor like glue but the tiles come up virtually bare.

Does the way the adhesive has been done look correct based on this pic? It is over ufh if that matters. And I followed the instructions on restarting the ufh to the letter of the manufacturers guidelines. Left it off for about 28 days and then turned it up very slowly day by day to get it up to temp.

I think the way the tiler has stuck them down is probably is ok and the adhesives starting to fail for a second time but I wanted to ask for your opinion if you can help?

This is an unbelievable predicament to be in.

Thank you all so much

The only things I could think would cause this would be the adhesive being down too long and skinning up before the tile was laid or that there was slot of dust on the back of the tile which has made it not adhere.
Very strange?!?
The actual bed isn't perfect but I would say ita adequate and isn't the problem
IMHO.

not buttered...

 

[Terry the tiler]

You butter believe it

 

[Toni]

Thanks Terry, I'd say no to both of those - he was working fresh with the adhesive so there is no way it would skin up and the tiles arent dusty at all really - I just checked an unopened pack and they are fine.

Thanks Antoino - is that absolutely vital? I didnt think it was as long as the tiles were smudged down a load when fitting.

Is buttering necessary as part of the tiling standards book (sorry I'm not sure what its called) - if it is then the tilers would be to blame but I'm not sure it actually is in there - so I think he's done enough here?

What's the adhesive?

 

[Toni]

Hi Impish

It was Granfix CSA: CSA FLEXIBLE - Instarmac - http://www.instarmac.co.uk/granfix-products/csa-flexible/

 

[Andy Allen]

Thermal shock...

 

[Toni]

Could it be thermal shock if you turn it on after 28 days and only very very gradually bring it up to heat?

 

[Simons70]

I think is the adhesive.Big format tiles,rapid set and underfloor heating is not a ideal mix.

 

[One Day]

Could be contamination to back of tiles? I'm not familiar with Granfix so can't comment on quality (or lack of).
Definitely should have back-skimmed them though!

 

[J Sid]

not buttered...

same

 

[One Day]

That adhesive is gypsum based. Is it an anhydrite floor? Did the tiler prime the floor first?
If he didn't prime the floor, the moisture would have been sucked out into the floor before maximum bond strength could occur.

UNI standards, he says, over 60cm to the side, buttering.
those tiles, are also made to banana, it is absolutely vital, but it is mandatory.

 

[Italy]

Then, I do not know if UNI rules also apply in uk.
in the last few days, I start to have doubts.

cazzo simons, sei ancora qui attaccato al culo?
vai tu o vado io a chiudere l'altro trend?

 

[Kyle Knowles]

Usually in the tile sheds, the 'best' tiler that they tend to recommend the most, tends to be the bloke who spends the most, or sends them a good flow of gullible punters.
He might also bring them butties on a morning, donuts on a Friday, hangs around for an hour drinking the free coffee etc...

By no means do they tend to be the best tilers though

only my opinion, obvs.

I do love a good chat my self I may be guilty of plying people with doughnuts lol

 

[Toni]

Hi Antonio,

I think it's Bs (British standards) in the U.K. I'm not sure if uni is the same?
