Using out of date Postcrete

[CCCS]

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Will the out of date Postcrete set as it should?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.

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.
