Best-before date tile adhesive

[Minkhe]

Hello!

I am wondering if anyone has experience with how critical it is regarding the usability of adhesive mortar that is "out of date" by 6 months compared to the best-before date?!

I have a batch of adhesive left that has been stored dry and warm, with the last date at the end of June this year, and I am planning to use it to lay slate in the entire basement at Christmas.

I had half a sack left that had been opened and stored in a dry space since Christmas. I planned to use it the other week. It looked fine. But when I took a scoop of it to start mixing, it was half-hard a few centimeters down into the sack. I probably could have broken up the lumps during mixing. But I didn't want to take the risk, so I had to buy new.

But as mentioned, it was an opened sack.

Have stored opened bags of tile adhesive (dry) for several years. No issues with the adhesive or the mixture. Manufacturers and retailers profit greatly from scaring us into buying new products.

Just as I suspected - thank you for the quick response!

Hello!

I've had some standing for 10 years. I threw it away now. I'm not prepared to take a chance that it still works. If it doesn't, the job to fix it is much greater than the cost of buying new.

Cement-based products often contain chrome-reducing substances to reduce the risk of the user developing chrome allergy. The best-before date of the product primarily concerns the fact that these substances are not active for more than about 1 year.

Cement is quite cement-based, and I wouldn't want to kick a cement bag that has been lying around for a number of years.. (It's usually rock hard)

The material in the fix that causes it to harden disappears over time from the mixture, which means that the speed of the hardening process can deteriorate over time.
