Product Information

Full details

Blue Circle General Purpose Grey Cement is an essential building material designed for professional contractors and dedicated DIY enthusiasts who require a reliable, versatile binder for a variety of masonry and structural tasks. The key benefit of this product is its expertly balanced formula, which enhances workability during application while ensuring rapid early strength and long-term structural durability. While it is highly flexible, users should note that as a 25kg bulk pack, it requires proper storage in dry conditions to prevent moisture absorption and hardening before use.

FAQs

Can I use this cement for interior plastering?

Yes, it is suitable for internal rendering and plastering applications, providing a durable and smooth finish.

How long does it take to reach full strength?

While it offers rapid early strength, it achieves its primary design durability after a 28-day curing period.

Can this be used for fence post foundations?

Absolutely, it is an excellent choice for general concreting tasks, including foundations and footings.

How should I store the 25kg bags?

Keep them on a pallet in a dry, covered area, strictly protected from dampness and rain.

Is this product suitable for bricklaying?

Yes, it is specifically designed to deliver reliable mortar for both bricklaying and blockwork.

Should I wear gloves while handling this?

Yes, cement is alkaline and can cause skin irritation; always wear protective gloves and a dust mask when handling.

Troubleshooting

Cement mixture is setting too quickly

Ensure you are using cold, clean water and working in shaded conditions to avoid excessive heat evaporation.

Surface cracking after application

This is often caused by drying too quickly; consider dampening the substrate beforehand or covering the finished surface to allow for slower, more uniform curing.

Difficulty achieving a smooth finish

Check the water-to-cement ratio; adding too much water can weaken the mix and make it harder to trowel effectively.

Setup, Compatibility & Care

To ensure the best results, always use clean mixing equipment and fresh water. When mixing for different applications, follow industry-standard ratios for mortar, screed, or concrete to achieve the desired strength.

Care and Storage: Store bags off the ground on pallets in a cool, dry environment. Once opened, seal the bag tightly or transfer any unused product into an airtight container to prevent hydration from atmospheric moisture. Avoid contact with eyes and skin; always use appropriate personal protective equipment like gloves and dust masks during mixing.
