Iron Oxide Brown 25kg Synthetic Pigment for Concrete and Mortar

Iron Oxide Brown 25kg Pigment

The Iron Oxide Brown 25kg provides a high-concentration coloring solution for cement-based applications including floor screeds, paving blocks, and decorative mortar. This synthetic inorganic pigment offers superior tinting strength and chemical stability compared to natural oxides. It integrates directly into the mix to ensure deep, consistent coloration through the entire depth of the material.

Built for the Job

Site supervisors and masonry contractors use this pigment to achieve uniform earth-tone finishes on large-scale construction projects. The powder form allows for precise weight-based dosing, which is critical for maintaining color consistency across different batches of concrete. It is specifically formulated to withstand the high alkaline environment of wet cement without fading or reacting. This makes it a standard choice for manufacturing interlocking pavers, roof tiles, and pre-cast concrete components where long-term color retention is mandatory.

• Coloring pedestrian walkways and driveway paving blocks to resist tire marks and weathering.
• Adding permanent brown tones to internal floor screeds in warehouses or residential garages.
• Tinting pointing mortar for brickwork to match existing architectural finishes on restoration sites.

Iron Oxide Brown 25kg Product Highlights

UV and Weather Resistance

The synthetic chemical structure prevents degradation from prolonged exposure to direct sunlight and heavy rain in outdoor environments.

High Tinting Strength

• Requires a lower dosage rate (typically 3% to 7% of cement weight) to achieve full saturation.
• Fine particle size ensures rapid dispersion during the dry-mixing phase of the concrete production.

What’s Included

• 1 x 25kg Bag of Iron Oxide Brown Synthetic Pigment

On-Site & Workshop Notes

• Always perform a dry mix with the cement and aggregates before adding water to prevent streaks or clumps.
• Maintain a consistent water-to-cement ratio across all batches as moisture levels significantly affect the final cured color.
• Store this material in a dry, covered area to prevent moisture absorption and caking within the bag.
• Wear appropriate respiratory protection and gloves when handling the powder to avoid inhalation of fine dust particles.
