Australian Builders Quick Set Concrete is a specially formulated rapid setting dry mix that blends sand, cement and aggregate in the one 20kg bag. It is designed for jobs where you need concrete to set fast, with a set time of around 15 minutes, so you can complete the task and move on quickly. Ready to use, you simply add water, and it is conveniently packed to give the correct amount of concrete for the right application. Quick Set is particularly handy for setting fence posts, poles and clothes hoists, where the fast set means you can hold posts in position without lengthy propping. As a premium quality, high performance product it produces a hard wearing, durable result. Because it sets quickly, only mix as much as you can place within the working time, and have your job ready before you add water. Always follow the safety, usage and handling directions printed on the bag, and take care when working with wet cement based products, as they are caustic to skin and eyes.
