The sand in it can go bad after a while. Especially if you open the package and don't seal it up again properly. Some Ungeziefer can get in there.

Same way with flour. You can get some meal worms in there.

Any powder can and will go bad if it is exposed to high humidity----I do not save powders for more than a few months due to the humidity in my area---

However, if your powders were inside the house in a dry place,they should be fine----open a bag and run your fingers through it---any of it sticking together or are there 'BBs'?(little pellets stuck together)

Normal thinsets can go bad from drawing moisture. If sealed in the plastic bags like Mapei's they should last quite a while. Rapid Sets are a different matter. About a year from production in a sealed bag it all you get from rapid sets or leveling compounds. Rapid sets get a little difficult to work with the further past expiration they go. Leveling compounds don't level once they are past expiration. They tend to just sit where you put them. Grouts expire too. Epoxy grouts can go a year or two before the epoxy won't cure correctly. Cementitious grouts can draw moisture and clump or they can have problems with color consistency.

I'm pretty sure I've seen Jaz state that you don't want to use thinset that's over a year old.
