Product Overview
Blue Circle Quality Assured Mortar Mix supplied in a 20kg bag is a pre-blended, ready-to-use mortar designed for bricklaying, blockwork, and general masonry repairs.
Formulated from a controlled blend of cement, fine graded sand, and additives, it provides a consistent, high-quality mix that only requires the addition of clean water.
The mix delivers strong adhesion, smooth workability, and reliable setting characteristics suitable for both interior and exterior use. Engineered for convenience and performance, it ensures even strength development and durable results across varied site conditions.
Features & Benefits
- Pre-blended composition: Contains cement, sand, and performance additives to ensure uniform consistency and quality.
- Reliable strength development: Designed to achieve dependable compressive strength suitable for standard masonry construction.
- Enhanced adhesion: Provides strong bond strength to brick, block, and stone surfaces for stable and durable joints.
- Consistent workability: Delivers a smooth, workable mix that spreads and trowels easily, supporting efficient application.
- Weather durability: Suitable for use in both internal and external conditions once fully cured.
- Time-saving preparation: Requires only the addition of clean water, eliminating the need for on-site batching or measuring.
- Controlled setting time: Offers sufficient working time for alignment and finishing before curing begins.
Applications
- Bricklaying and blockwork: Suitable for general masonry construction and wall building.
- Pointing and repair: Ideal for repointing joints and carrying out patch repairs in existing mortar.
- Stonework and paving edges: Provides a uniform jointing mortar for bedding or repairing paving slabs and natural stone.
- Internal and external use: Formulated for use in sheltered or exposed applications with consistent performance.
Installation Guidance
- Surface preparation: Ensure all masonry units are clean, sound, and free from loose material, dust, or oil.
- Mixing: Empty the contents into a clean mixing container and add clean water gradually, mixing until a smooth, workable consistency is achieved.
- Application: Apply using a trowel, jointing tool, or suitable pointing iron depending on the task. Avoid re-tempering or over-watering the mix once set has begun.
- Finishing: Tool or shape joints as required before the mortar fully hardens to achieve the desired profile.
- Curing: Protect freshly applied mortar from rain, frost, and rapid drying for at least 24 hours.
- Cleaning: Clean tools and mixing equipment immediately after use with clean water.
Compliance & Performance
