Concrete Chemicals carries a full line of iron oxides and chrome oxide. Iron oxides are durable, UV resistant, colorants which can be used to color concrete, grout, mortar, stucco, swimming pool plaster, and wall plaster. Concrete Chemicals offers reds, black, green chromium oxide, yellow, and blends upon request. For blues, Concrete Chemicals offers cobalts.

For do-it-your-selfers who are working in the backyard with hand mixing tools, iron oxides may be purchased in one-pound bags, five-pound bags, or fifty-pound bags.

In order to calculate the number of pounds of color needed for your backyard job, count the number of sacks of cement you will be using for your project. Note that white cement will produce bright colors, while gray cement will produce muted, darker colors. Since all gray cements are different, it is recommended to test a little of your gray cement with the selected iron oxide. Add as much iron oxide color in the test amount of cement until the desired color is achieved. Then scale up. Again, white cement shows off color much more than gray cement. The same test with white cement may reveal you need only one half pound of red-brown iron oxide for one sack of white cement. Please feel free to call if you’d like to discuss your project.

Custom blends are available. Send us your desired color and we will blend iron oxides to match the color. Custom color development: $140 per hour of bench time. Allow 3 days for custom color matching. Add $50 for “Rush Development.”

Prices for one pound of iron oxide start at $6 per pound and decrease as volume increases. Email us or call for consultation (888)867-5701.
