Mason mix has no aggregate in it and has more sand than a concrete mix, also if the sand to cement ratio differs depending on whether you are laying brick/block or stone. You can set posts without cement, just tamp the back fill every couple of inches, if you are going to use mortar or concrete, just remember to put the bottom couple of inches of the post into a gravel bed before you put in the cement mix of your choice, this helps stave off the rotting of wooden posts, when I set posts I generally use dirtcrete, I just buy a couple of bags of cement, mix 1 shovel of cement and about 3 shovels of the dirt from the hole, then tamp it back in, my 6 foot privacy fence weathered hurricane Katrina, and it is still standing…

Great question. I am curious to read the answer. We will be setting vinyl posts and this question might help. We recently purchased the used picket fence which had been in the ground a few years. The mortar mix was still on the bottom of a few posts... several tap tap TAPS with a hammer, and it all fell off.

What's the difference between Concrete Mix and Mason Mix? Can Mason Mix be used to set deck posts? I got some free bags of Mason Mix off CraigsList and was wondering of I can use it for setting deck posts.
Thanks,
John
