Key Features
- General Use: This cement works for almost every standard construction task — you don’t need a specialist cement for everyday building work
- ASTM C 1157 Certified: This means the cement has been tested and meets an internationally recognised standard for quality and performance
- 42.5kg Bag: The standard bag size used across the construction industry — enough for a good batch of concrete or mortar without waste
- Sets Hard Over Time: Cement doesn’t just dry — it goes through a chemical process called hydration that makes it get harder and stronger over several days. Keeping new concrete moist for at least a week helps it reach full strength
- Mix It Right: Too much water makes weak concrete. Use only as much water as you need to make the mix workable, and no more
- Keep It Dry: Store bags off the ground and under cover. Even a little moisture can start hardening the cement inside the bag before you use it
