Review: Bostik Cementone Rapid Setting Cement is a quick and convenient solution for various cementing projects. This cement offers rapid setting times, allowing for faster completion of tasks. It is easy to mix and apply, making it suitable for both professionals and DIY enthusiasts. One of the notable features of this cement is its fast setting time.

The cement's versatility is another advantage. It can be used for a wide range of applications, such as patching cracks in concrete, setting fence posts, or repairing damaged surfaces. Its durability and resistance to water make it suitable for both interior and exterior projects. However, it's worth noting that the rapid setting nature of this cement leaves less time for adjustments or corrections. Once it starts to set, it becomes difficult to manipulate or reposition. Additionally, the rapid setting time can be a disadvantage if you require more working time or have complex projects that demand precise adjustments. Overall, Bostik Cementone Rapid Setting Cement is a reliable option for quick cementing needs. Its fast setting time and versatility make it a convenient choice, but it may not be suitable for projects that require extended working time or intricate adjustments.
Review: I needed some quick setting cement to secure a fence post repair spike in place after fixing it to the post. The addition of the cement to the repair has made the post really solid. Worked very well. Recommended.
