If I am using this product to set fence posts, how soon can I install my fence? On average, based on 24" deep and 10" diameter hole.
Asked by: FastBuild
If you set all of your post with the Fast Set Concrete and give at least an hour before you start hanging the fence, you should be fine.

The manual says to use mortor or thinset.

No, you would need to use the Sakrete Sand Mix Topping & Bedding Mix. This material is considered a high strength mortar.

Rated 1 out of 5 by from Slow setting Mixed thoroughly and poured in hole on a 80 degree day with low humidity. 3 hrs later you can still stick a stick in it. Super soft. Quikrete red bag is a much better mix. You can drive on it in 2 hrs. Now I'm stuck packing these heavy bags back for a refund. Not to mention the time wasted on the project.
