What Customers Are Saying

The Sakrete Fast Setting Concrete Mix is a convenient product for quickly setting fence posts, mailbox posts, and other small concrete projects. Key features include a fast setting time of around 30 minutes, easy mixing and application, and a strong, durable hold. Some users noted the fast setting time requires working quickly before the mix hardens, and it may not be suitable for larger or more complex projects needing a smoother finish. Overall, this product provides a good value for DIY homeowners looking to complete small concrete work efficiently.

Love the quick setting feature of this product. I used it to set a 4x4 pole in the ground so I could mount my retractable water hose to it.
