Fence Post Mix 

To install fence posts using Postcrete or a Fence Post Fixing Mix, we recommend placing the fence post into the hole (at the correct depth for the height of the fence), filling the hole one third with water and emptying one bag of contents of the bag into the hole on top. Giving it a slight mix to ensure all the Postcrete/Post Fixing Mix is wet, then add the remaining required bags evenly around the circumference of the post, ensuring there is enough water to wet all of the Postcrete. 


To finish the installation, cover the Postcrete/Post Fixing Mix with the soil from digging the initial hole to provide a tidy finish.

Please note: The minimum working temperature for Postcrete is 3 degrees centigrade.

Why use Postcrete or a Post Fixing Mix?

Postcrete usually sets within 5-10 minutes, in suitable conditions with the solution stiffening within 1-2 minutes. Compared to standard industrial concrete, which takes anywhere from 24-48 hours to fully set, the quick dry time means you can install one fence post after the other quick succession, keeping a consistent pace across the installation.

In addition, you are able to hang fencing, garden gates, trellis and other heavy loads on a post set with fast-setting Postcrete inside four hours. That means a project that could have taken a weekend with standard concrete, could easily become only a days work.

Postcrete or a Post Fixing Mix is easy to use, as it is basically pre-mixed concrete, just sprinkle with clean water and then mix.
