What Customers Are Saying

The product provides a convenient and time-saving alternative to concrete for setting fence and mailbox posts. Many customers found it easy to use, with the product expanding and hardening quickly to securely hold the posts. However, some reported issues with the product not performing as expected, and it may not be as durable or suitable for larger or heavier applications as concrete. Careful following of the instructions and product limitations is recommended.

This did not expand very much But might be strong

Would Not Recommend

The competitive product expanded 50% more than this one did. To fill two post holes with a combination of rock, wood, foam and dirt, I needed to use two bags of this product and one bag of the competitive product. It’s pretty strong but also can wobble a little even after compacting the surrounding dirt and rocks. Not recommended in sandy soil or previously used post holes with cement removed unless most of the hole is filled with rocks and concrete.

What a mess!

Would Not Recommend

The bag split open and the mix started pouring out—I must have overmixed it. It got all over my hands and legs and won’t come off, even with gas. It just turns into a sticky goo. I’ll have to try scrubbing it off and hope that works. They should put a big red warning: DO NOT mix longer than 30 seconds. I was only slightly over and this still happened. Won’t buy again—I'll stick with concrete, it’s easier to use.

NO FUMES - SAFE & EASY TO USE INSIDE

Would Recommend

We used this product to secure a utility pot inside a giant $$$$ glazed planter that did not have a flat interior bottom. Lined planter with 8 layers of GLAD WRAP ... placed a heavy plastic tray in the bottom and then put a heavy utility pot in the center. We used a "box of rocks" to hold the utility pot in place and poured the FAST 2K around it ... now we can safely stand our beautiful 7' artificial tree ... PERFECT SOLUTION !!

My second use. Love it!

Would Recommend

Easy to use, expands and holds, and lasts. I have used it twice, both times to hold a skinny pole for a 6-foot tall spinner. The first one was a year ago, and it's still holding strong. Be sure to have your pole or post in place exactly where you want it. Once this stuff starts expanding, you shouldn't be moving anything. I'd use it again in a heartbeat.

Ideal for one post.

Would Recommend

I had one fence post to install and did not want to buy a whole bag of cement. This did the job.

worked better than expected BUT

Would Recommend

I need to reinforce to posts on my fence. This worked better than I expected. To me easier to handle than concrete. It states on the bag that it should stick to the post. I found that is did not appear to adhere to the post very well. I ended up using on bag then came back 24hrs later using a second bag pouring it directly into the gap between the post and dried foam. All in all worked great. I yes I use recommended and use again

Good product

Would Recommend

Great product , but it will only get you around 20”-22” in height . After the foam has set up and expanded . That was in a 6” hole , as they advertise 36” in a 6” hole .
