The bag is heavy.

I poured the mix into the hole with the fence post and added water. It eventually hardened and made the post secure.

Amazing

Would Recommend

Holy smokes this is no joke, this set within maybe 20 minutes and was hardened within a few hours. We made hand print stepping stones with the kids and they loved it!

Great product with one caution

Would Recommend

This product is quick and easy to use. Great for setting posts. However, do not buy too far ahead of your project because it can harden in the bag over time and become unusable.
