Frequently Asked Questions on Post Mix

How many bags do I need?
As a rule of thumb 1 1/3rd bags per fence post hole for 75 x 75mm & 100 x 100mm size fence posts.

For example this means eight fence panels and posts would need eleven bags of Post Mix

The larger the posts and the bigger the holes the more Post Mix that will be required. A gate post may require three or four bags.

Bags are normally 20kg in size.
