What Customers Are Saying

Customers overwhelmingly praise this fast-setting concrete for its speed and simplicity. The product hardens in 20 to 30 minutes without mixing—users simply pour the dry mix into post holes and add water from a hose. Most reviewers highlight how this eliminates labor-intensive preparation, allowing multiple installations in one day. The 50lb bag size is noted as ideal for single posts without waste. Customers consistently report strong, stable results for fence posts, mailbox posts, and flagpoles, with posts remaining secure long-term. A few mention isolated issues like damp bags or excessive gravel, but these are uncommon. Overall, reviewers strongly recommend it for post installation projects.

This product was used to set fence post. The product worked as advertised. Easy to mix, sets fast and appears to have good strength.

I use the quickset cement to set for post for a trellis in my yard, the cement was easy to work with and headache consistency, even when I didn’t quite had enough water or added a little too much water to the mix. Wow agitating it. All of the bags that I bought were in real good shape and not a lumpy so I know they hadn’t gotten moist previously wow in the store.
