How long can you store tile adhesive and grout?
Hello,
Does anyone know if it's safe to use old grout and filler (Casco)? The product sheets say one year. Bought in January 2008.
I bought too much when I laid tiles in 2008. The basement room that I didn't get to then, I now plan to tackle.
Grateful for advice.

Today is the 2nd of APRIL and if it had been well-sealed and dry, I would use it.
Try mixing a little and see how it feels after it has burned.
I asked the same question a few years ago to a man who worked at Optiroc.
He suggested... (it sounds a bit strange now when trying to recall the conversation).
Anyway, it's some additive that's supposed to bind substances that can easily cause allergies in the mortar.
You can get nickel allergy, for example, from concrete dust (unburned).
They couldn't guarantee that "protection" after the best before date.
I have too little chemistry and concrete knowledge to assess this, but he didn't say anything about the mortar becoming "old".

Then the only question left is what becomes bad. And how does it show?
It's good to have a manufacturing date and some idea of how old it can be allowed to get.
For example, different glues and sealants in cartridges that "quite soon" become impossible to get out of the cartridge, even unopened.
Well-packed cement-based products last much longer.
Then again, it's not good for the bags to be left outside like at the lumberyard.
Doing a small test is good if you're unsure.
