What is postmix used for?
Postmix is a ready-to-use concrete mix designed for fixing fence posts, gate posts, pergolas, and other garden supports securely into the ground. It provides strong, stable foundations without needing to mix traditional concrete.
How do I use postmix to set a fence post?
Dig a hole, place the post in position, add postmix around it, then add water. Hold the post in place while the mix sets. Most postmix products harden quickly, allowing you to hang panels shortly after installation.
How long does postmix take to set?
Postmix typically starts to set within a few minutes and hardens rapidly, giving initial strength in under an hour. Full strength develops over time as the concrete cures.
How many bags of postmix do I need per post?
As a general guide, one 20 kg bag is often enough for a standard fence post in normal soil. Deeper holes or larger posts may require more bags for extra stability.
Can postmix be used for timber, metal, and concrete posts?
Yes. Postmix is suitable for timber, metal, and concrete posts, making it a versatile solution for most fencing and garden projects.
Is postmix suitable for UK weather and outdoor use?
Yes. Postmix is designed for outdoor use and is durable in rain, frost, and varying temperatures, helping keep posts secure for many years.
Do I need to mix postmix before using it?
No. Postmix is a ready-mixed product. You simply pour it into the hole and add water, making it faster and easier than traditional concrete mixing.
