How long do you leave porcelain to dry before drilling etc

[LJD]

Lucky it was a full tile that "popped ". I was fitting a V&B bathroom cabinet today. Adhesive is 3 days old. As I tightened it all up .I could here the tile "lift off" .very easy for me to re do etc .

But would have expected the adhesive to be good in that time ?

Thanks

What adhesive was used?
Did it leave the adhesive on the wall or tile?

Photo?

Mapei Adesilix P9 . Will remove basin unit tomorrow . Then have a look. Client need to check heights etc .

Cheers for advice. I seem to get very good help here .

Something is very amiss, because if I'm not mistaken that adhesive is a rapid set! No way they should pop off after 3 days.
Give us some photos of the wall and the back of the tile... Will know better then.

Pics by mid morning !

In their spec sheet it does say the bed should be about 5mm I am using a 10mm trowel. wonder if the extra 2-3 mm when bedded is the issue ?

 

[One Day]

A 10mm trowel will give approx 4mm bed if compressed. It won't be the problem.

 

[LJD]

I measured the bed i was getting after buttering the tiles. On average it was 7mm

 

[JohnMar79]

What size were the tiles? Large format and limits of the adhesive as you say 5mm max bed recommended has probably contributed to it.

 

[LJD]

300x300 mm

 

[One Day]

Were the tiles very cold before fixing?
Is the background waterproof?
Was your mix water clean?
Did you add more water to a mix which was already setting up?
Was the adhesive in date / stored correctly?
So many variables?

Tomorrow, check to see if some adhesive which is now uncovered, has hardened up.
Pics will be a big help.

 

[JohnMar79]

7mm bed thickness on a 300x300 seems a little on the thick side presume the walls weren't flat? Presume decent coverage on the back like 80% +. If so I'd day adhesive was too thick.

 

[LJD]

What also might have been the problem is the raw plugs and doing the brackets up .I wonder if by doing them too tight the rawplug was pulled from the wall "popping the tile " its only a theory , will see the truth tomorrow !!

 

[LJD]

Fresh water. No added water . fresh adhesive . Walls sealed with Mapei primer G . It was just old walls after the old tiles had been removed and the old adhesive cleaned off etc .

 

[Flintstone]

Your tile shouldn't pop off the wall no matter what you do with your rawl plug, and the bed depth hasn't caused this problem either, I can assure you that. I guess the tile will be clean, adhesive skinned over and no back butter

 

[LJD]

Good tiles and back buttered . Nothing to hide, going to answer all question correctly. Nothing like learning !

I've only had one issue with a rapid set going off VERY slowly and it was Topp's own brand by Palace. They weren't at all interested and it did eventually set.

Yes but surely not three days .
Sounds like topps and they reckon they want to attract trade customers

I think p9 is a slow set

Morning ! Ok adhesive came off wall surface . I have done a depth measure and it’s 7mm exactly . Tile has 80% coverage .

 

[One Day]

No bond on the wall. Almost like it's been pva'd, but I know you didn't!

 

[LJD]

No PVA !!!

 

[LJD]

Mapei G1 was used correctly on the plaster

 

[Italy]

It seems that the primer was not well dried.
Once it happened to me,
It was cold and primer was not yet dry.
After a week, the tiles were like your photos.

 

[LJD]

Primer had 24 hours plus to dry in a nice warm house with plenty of airflow !

 

[Dumbo]

Did you dilute it

 

[LJD]

yes !! Followed the guide lines etc. I have re done the tile tonight and will drill it Sunday .
