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?

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.

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 ?

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

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

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

300x300 mm

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.

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.

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 !!

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 .
