Coarse Rapid Setting Post‐Mix 20 kg
Ideal for secure, stable installations of fencing and posts, our pre‑blended rapid‑set concrete mix delivers a quick, reliable foundation for timber, metal or concrete posts.
Key Features:
- Specifically formulated as a rapid setting post mix – sets firm in approximately 10 minutes (depending on ambient conditions).
- No pre‑mixing required – simply half‑fill the hole with water, pour the Post‑Mix directly into the hole and place your post.
- Suitable for fixing all types of posts including wooden fence posts, metal posts and concrete posts.
- Ideal for both DIY fencing and professional fencing contractors. For example, contractors often allow 1½ to 2 bags per fence post (depending on hole and post size).
- UK weather‑ready: quick set ensures minimal delay in your project, even when conditions change.
Usage & Instructions:
1. Dig the hole to required size for your post.
2. Place the post in the hole and bring to correct level and position.
3. Half‑fill the hole with clean water.
4. Pour the pack of Post‑Mix evenly around the post until it is above the water line. If any dry powder remains visible, add a little more water until it is fully absorbed.
5. Adjust and brace the post if necessary; the mix firm’s up within 2‑5 minutes and fully sets in around 10 minutes (time varies with temperature). Avoid use if substrate/air temperature is below 5 °C.
Applications:
- Garden fencing, boundary panels, pergolas
