## Questions & Answers

**Q: Could this be used to fill a plaster of Paris mold?**
A: Not that I'm aware of, it doesn't really say on the package but it does sit up very fast and is very durable. Sorry but that's the best I can answer your question.

**Q: Could this be used to hold an 8x8 supporting a substantial weight?**
A: I had to replace a 4x4 post for my mailbox and used this 2K Post Back Fill. I already had a deep hole in the cement, so this stuff fills up the gaps beautifully all around and keep the post solidly planted. I'm not sure about 8x8, weight is not the issue here but you would need a "solid" hole like in my case to hold to post, then this foam would then fill up any gaps. Good luck.

**Q: Can this be used to form the deck list foundation where the 8x8 post then sits on top held by a bracket anchored in the foundation?**
A: No, Fast 2K can only be used for installing posts that are sunk into the ground.  It cannot be used as a foundation material nor can any brackets be anchored into it.

**Q: Would this be good to use for posts for a horse fence strong and sturdy?**
A: Yes, also sets up quick and should be good for a horse fence.

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!
