Fast 2K Fence Post Mix and Concrete Alternative and Replacement for Fence Post and Mail Post Installs. 32.8 oz Bag of Expanding Composite Footing Compound

Worked great for 4x6 fence posts. I tried Fast 2K and another brand for my fence. Fast 2K is far superior. Be careful not to make the hole wider or deeper than necessary or you’ll end up using more than is needed. It sets up quick and holds up strong.

It's a great product. Very easy to use and it sets like concrete.

Fast 2K Fence Post Mix exceeded my expectations! I was looking for an alternative to traditional concrete that would save me time and effort, and this product delivered. The setup process was incredibly simple—just mix, pour, and let it set. Within minutes, the post was firmly in place, and I didn't have to deal with heavy bags of concrete or long curing times. I also appreciate that it expands to create a strong and stable hold, making it ideal for fence posts and other outdoor projects. Plus, it's lightweight and easy to store, which is a huge bonus. If you're looking for a fast, mess-free way to secure posts without the hassle of concrete, this is the perfect solution. Highly recommended!

Didn't work for making my bird feeder pole.

Worked awesome for a mailbox repair. Cleaned the area a bit, and it filled/hardened pretty quick.
