Iron Oxide Blue Pigment, Synthetic Cement Grade, 25kg Bag

Iron Oxide Blue Pigment, Synthetic Cement Pigment

The Iron Oxide Blue Pigment provides a durable and lightfast coloring solution for various cementitious applications. This synthetic powder integrates directly into dry mixes or wet concrete to achieve a consistent blue hue across large surface areas. Site supervisors rely on this specific grade for its resistance to alkali and weather conditions, ensuring the color remains stable even under intense UV exposure.

Built for the Job

Professional contractors utilize this coloring agent primarily for decorative concrete work and masonry. It is essential for projects requiring aesthetic uniformity, such as interlocking pavers, architectural facades, and colored floor screeds. The fine particle size ensures even distribution throughout the mix, preventing blotching or streaks when applied correctly. Using this material in the correct dosage allows for a range of shades from light sky blue to deep azure, depending on the cement base used.

• Coloring of concrete blocks, driveways, and paving stones.
• Tinting of mortar, stucco, and plaster for decorative finishes.
• Pigmentation of pre-cast concrete elements and architectural panels.

On-Site & Workshop Notes

• Perform a trial mix to determine the exact dosage required for the desired shade before full-scale application.
• Store the bag in a cool, dry area to prevent clumping or moisture absorption which can affect dispersion.
• Add the powder to the dry aggregate and sand first, mixing thoroughly before adding water and cement.
• Grey cement will produce more muted, earthy tones, while white cement is necessary for bright, clear blues.
• Wear appropriate respiratory protection and gloves when handling the powder to avoid inhalation of fine particles.
