Does tile adhesive go bad??

[mredd]

Hi, If cement based adhesive is still in date but slightly hard to touch in an unopened bag. Is it Ok to use? How would you know it has "Gone bad"? :huh2:

Do you mean when holding the powder in your hands or feeling through the bag. If the later then it could just be compressed. if there are hard lumps then its a chance its got damp.

 

[mredd]

It is the latter, if there are some lumps is this still OK?

 

[Gazzer]

can the lumps be flattened back into powder if not then I would ditch it.

 

[mredd]

I will check, thank you for you info.

Normally there's a 12 month(ish) life in unopened bag

I generally throw everything out of the lock-up every few months. Sometimes its worth having thick rubble sacks to double bag open adhesive bags with.
