Using out of date Postcrete
Discussion
I’ve got three bags of unopened Postcrete that I was going to use for two wooden fence posts. They’ve been sat in my garage for about a year. The use by date is April this year.
Until a few months ago I didn’t know that cement “went off”. I found this out when I used a small amount of premixed mortar to repoint a few bricks. A few weeks later the new mortar was like dust and crumbled when I touched it. This was a bag I’d opened a couple of years before and left in the garage.
Will the out of date Postcrete set as it should?
I realise three new bags will only cost around £20. It’s more I just don’t like sending stuff to landfill that will be there forever.

If it’s stored well, such that it’s still dry and hasn’t been exposed to too much moisture and formed clumps, I’d use it. Also on the grounds that it’s holding posts, not building a house.
I read somewhere - may not be true - that the expiry date is more to do with chromium or something in the mix that becomes more environmentally unsound or increases dermatitis risk, rather than reduced efficacy.

My advice would be, use the postcrete, don`t use wooden fence posts.
I did a couple of years ad hoc work for a mates fencing co, 90% of the work we did was replacing relatively new fencing that had been put up with wooden posts, with concrete posts. Wooden posts rot and snap off at ground level.

I know what you mean. Earlier this year I dug out some broken wooden posts. I used timber again, I just prefer the look over concrete posts.

The two posts I’m fitting now are in a different position to the two existing ones (which are sound after 25 years).

Good advice. Either metposts + wood, or concrete fence posts.
I’ve used metposts in the past they didn’t stop the timber rotting. I used https://www.postsaver.com/ on the posts I fitted earlier this year.
If it's the Postcrete that proudly proclaims to be in a waterproof bag it should be fine. I used an unopened bag, that has been in the shed at least 5 years, to set a new washing pole the other week. Pole still there this morning, after Arwen whipped through last night. My neighbour's fence, however, was not so fortunate.
