Iron Oxide Pigments
The use of iron oxide colors in concrete has grown to be the single largest application for this type of pigment. This increase in usage has created a demand for better technology and quality control throughout the concrete industry.
Solomon Colors Dry Integral Color is the simple, cost effective way to color concrete. Create consistently colored concrete using the Solomon pigment products. Each batch of blended pigments is checked for quality and consistency. Packaging in convenient sizes of re-pulpable paper bags enables a large range of color possibilities without the need to open bags to weigh product.

Good drainage and compacted aggregate add many benefits to decorative concrete. Pouring concrete over an inconsistent sub-grade or mix of dirt, plastic, wood, asphalt and existing concrete will not cure evenly. These types of sub-grades will force the majority ofwater to the surface to evaporate, causing efflorescence in those affected areas. In hot conditions, dampen the sub-grade before each pour to keep moisture in the concrete to allow better hydration. Keep the sub-grade moisture consistent throughout the day without allowing the water to pool. Jobs requiring a vapor retarder, and job sites having high heat and low humidity conditions, are exceptions to pouring over plastic. Pouring concrete directly over plastic can lead to numerous problems including excessive bleed water, uneven drying time, shrinkage, cracking, and efflorescence. Consider adding 2"-4” of sand between plastic and concrete. If pouring directly over plastic, mix design may need to be altered. Slump and placement techniques require tighter tolerances, and finishers need to be well trained and experienced
- Sealing
Protect the beauty of your decorative concrete project with Brickform solvent or water base sealers. Brickform sealers are available in high gloss, medium gloss, or matte finish appearances.
Applications & Uses
- Markets
- Industrial Additives End Use
- Mixing
- The drum must be cleaned. Do not use reclaimed slurry water or reclaimed aggregates.
- Add approximately two-thirds of the mix water and one-half of the aggregates to the drum, then add color pigment at full charging speed. Add the balance of the ingredients (water, aggregates, cement and admixtures) and mix at a full charging speed for a minimum of 5 minutes (60 revolutions) when using Solomon Color ColorFlo liquid color, or 10 minutes when using dry pigment powder or granules (100 revolutions), before pouring concrete (6.13-7.36 m2/L).
- When using small or smooth rounded aggregates, do not add the bag to the truck. Add only the color pigment by opening the bag and pouring all color into the truck.
- Mixer should be loaded to a minimum of 40% capacity to ensure good color dispersion.
- Be sure to use the same mix design and maintain consistent water-to-cement ratio throughout the jab. The use of plasticizers, water reducers and air entraining products designed for colored concrete production are acceptable. Solomon Colors strongly recommends the use of test slab to determine final color outcome.
- After pour has begun, adding water to the load to improve workability often causes color variation.
- When using Solomon Colors pigments packaged in repulpable bags, slit the bag along the top dotted line, and completely remove and discard the top portion of the bag. Following these guidelines will destroy the paper bag and provide the best dispersion of the pigment.
- Additives
- DO NOT use calcium chloride. This product can cause discoloration in the form of light and dark areas in the finished product. Non-chloride accelerators, including hot water, are acceptable accelerators.
- Check the compatibility of the mix design (plasticizers, water reducers and air entraining products) with the addition of color by pouring a test slab to confirm the preferred results.
- For Vertical Applications
(CAST-IN-PLACE OR TILT-UP WALL)
All forms should be cleaned thoroughly prior to use or reuse, and applied release agents should be non-staining. For best results, forms should be free of cement residue from any prior concrete pour of a different color. Vertical wood forms should be made of medium-density overlay plywood. For color uniformity, methods and material used in preparing the forms should be consistent through the completion of the jab. Lightly and uniformly sandblasting vertical surfaces Is highly recommended to remove minor form marks and any colored residue resulting from water, cement and coloring agents bleeding toward the forms during concrete placement.- Limitations
Alevel of 7% (by dry weight) color based on the weight of total cementitious material used is the color saturation point. Color added in excess of 10% (by dry weight) can reduce the overall strength of the finished product. Conversely, a level of color below 1% can cause irregular coloring and general “washed out" appearance, The suggested “optimum” range is 2% to 4% pigment loading based on total cementitious material weight
When using our 908 CARBON BLACK, a level of 2% color based on the weight of total cementitious material used is the color saturation point. Color added in excess of 2% will not provide additional benefits. The suggested “optimum” range is 1% to 2% pigment loading based on total cementitious material weight, (Cement, Lime, Fly Ash, GBFS and other Pozzalanic materials). Due to the particle size of Carbon, it has a tendency to dissipate out of concrete over time, Solomon Colors recommends sealing the concrete with a Brickform concrete sealer. It is important to maintain a proper sealer maintenance program to protect the surface color, as this will help slow this process down and in some cases prevent it. Carbon particles will decrease the amount of entrained air during the mixing process. Monitoring air content to specification will be necessary

Technical Details & Test Data
- Curing
- DO NOT fog or spray water on the surface during the initial curing period.
- DO NOT cover the surface with plastic.
- Failure to follow these guidelines can lead to uneven curing and coloration.
Solomon Colors recommends the following products and curing method:
BRICKFORM CURE & SEAL products meet the ASTM Standards C 309 and C 1315 for curing most new colored architectural concrete flatwork. Apply at a rate of 250-300 sq. ft. per gallon (6.13-7.36 m* per liter) once the slab is hard enough to be walked on without marring the surface.
Use caution when applying these products in high heat, direct sunlight, and/or in windy conditions. Please reference the appropriate Cure & Seal Technical Information Sheet for a full description of the product use, limitations and precautions.
Proper curing, along with maintaining a low slump and protecting the surface against water penetration, reduces the possibility of efflorescence. If efflorescence does occur, remove efflorescence using BRICKFORM E-ETCH. Fallow with a light scrubbing or the use of a low r.p.m. rotary scrubbing machine.- Technical Specification Data
Composition and Materials: Pigments are pure red, yellow, and black iron oxides. Solomon Colors has expanded the color range by formulating laboratorycontrolled, high tinting strength pigment blends. Each of these colors is 95% to 99% minus 325 mesh particle size. Solomon Colors iron oxides are permanent, inert, stable to atmospheric condition, sunfast, limeproof, and free of deleterious fillers and extenders. All Solomon Colors pigments comply with ASTM C979 for integrally colored concrete and are produced and tested to an established plant standard.
- Solar Reflectance Index (SRI)
SRI is the measure of a surface’s ability to stay coal in the sun by reflecting solar radiation and emitting thermal radiation. The SRI value is calculated according to ASTM E 1980. Please visit the Solomon Colors
- Preparation Of The Sub-grade
Preparing the subgrade with compacted aggregate, free of frost, with no standing water is essential. In hot conditions, dampen the subgrade before each pour to keep moisture in the concrete to allow better hydration. Keep the sub-grade moisture consistent throughout the day without allowing the water to pool. Pouring concrete directly over plastic can lead to numerous problems including excessive bleed water, uneven drying time, shrinkage, cracking, and efflorescence. Consider adding 2” to 4” of sand between plastic and concrete. If pouring directly over plastic, mix design may need to be altered. Consult with your ready-mix concrete supplier.
- Mix Design
The key to a uniform concrete color is consistency throughout the job.
• The mixer drum should be clean with little or no buildup on fins.
• Mixer should be loaded to a minimum of 30% capacity to ensure good color dispersion.
• Consistent color can only be achieved by using the same mix design throughout the job (same sand, cement, admixtures, aggregates, and waterto- cement ratio).
• Consider adding UltraFiber 500® cellulose fiber reinforcement to your decorative project. UltraFiber 500® provides excellent secondary reinforcement, is invisible in concrete, and yields an esthetically perfect finish with no special finishing practices. Links to Ultra Fiber 500® TIS
