Question 1

1. How much Postcrete should I use per post?

Accepted Answer

This depends on factors like the size of the post you’re using, but a good rule of thumb is 1-2 20kg bags of post mix per post. Larger or heavier posts may need more.

Question 2

2. How long does Postcrete take to set?

Accepted Answer

Most post mixes, including Blue Circle Postcrete, set within 5–10 minutes, although they take a few hours for it to cure fully.

Question 3

3. Postcrete vs concrete – what’s the difference?

Accepted Answer

Postcrete bags contain a pre-mixed blend of cement, sand, and additives that’s designed to set quickly. Standard concrete takes much longer to set, but is also stronger than post mix, and suitable for a wider range of projects.
