Product Information

Full details

Blue Circle Mastercrete Grey Cement is a premium trade-grade building material designed for professional contractors and dedicated DIY enthusiasts who require a versatile, high-performance binder for concrete, mortar, and render applications. This pack of ten 25kg bags offers a total of 250kg of material, featuring durable plastic-wrapped packaging for improved moisture resistance during storage. While this product provides exceptional workability and strength, users must exercise caution due to the highly alkaline nature of wet cement, which necessitates the strict use of protective equipment during mixing and application.

FAQs

What is the total weight of this pack?

This pack contains ten 25kg bags, resulting in a total weight of 250kg.

Can I use this for internal and external work?

Yes, Mastercrete is suitable for both internal and external concrete, mortar, and render applications.

Is the plastic packaging waterproof?

The plastic packaging offers enhanced moisture resistance compared to traditional paper sacks, but it should still be stored in a dry, covered area.

What safety precautions should I take?

Always wear gloves, goggles, and protective clothing. Wet cement is alkaline and can cause skin irritation or chemical burns.

How should I dispose of the packaging?

Check your local waste management guidelines regarding the disposal of plastic packaging that has been in contact with cement.

Troubleshooting

Mix is too stiff or difficult to work with

Gradually add small amounts of water until the desired consistency is reached, taking care not to weaken the mix with excessive moisture.

Surface cracking after drying

This is often caused by rapid moisture loss. Keep the finished surface damp or covered with plastic sheeting to ensure proper curing.

Slow setting times

Check ambient temperatures; cement sets slower in cold weather. Ensure it is not being applied in near-freezing conditions without proper additives.

Pros and Cons

Pros

  • Durable plastic packaging provides excellent weather protection.
  • Highly versatile for use in concrete, mortar, and render.
  • Reliable strength and performance consistent with trade standards.
  • Convenient 25kg bag size is manageable for manual handling.

Cons

  • Requires strict adherence to PPE safety guidelines due to alkalinity.
  • Cement is heavy and requires proper lifting techniques to avoid injury.
  • Subject to shelf-life limitations if stored in humid environments for extended periods.

Setup, Compatibility & Care

To ensure optimal performance, store the bags in a cool, dry place off the ground, preferably on pallets, to prevent capillary moisture absorption. When preparing for use, always wear alkali-resistant gloves, eye protection, and long-sleeved clothing, as wet cement can cause severe skin irritation or chemical burns. Use clean, potable water for mixing; contaminated water can alter setting times and reduce final strength. After application, protect fresh concrete or render from extreme temperatures, high winds, or rain to allow for uniform curing. Cleaning of tools should be performed immediately after use before the material sets.
