/What's being overlooked is Postcrete *is* concrete in convenient ready
mixed dry form.

The magic of it holding the post quickly is down to it being ram-packed
in slightly damp rather than wet.

If bags are convenient or you only need a couple of posts worth,
Postcrete makes sense. if you have a lot to do, mixing by hand might be
better - just don't add water (if the sand is wet) or just add a little
to help it clump. /q

Nah it's accelerated set, on purpose. Also don't recognise these advices to put in dry and Then add water??? Istr its half fill hole w water, then throw the dry gear in, hold til set as nbecess
