Cement Pigment

Printable Concrete Pigment How-To Guide

Step 1: Preparation

• If mixing in a bucket or a mixing drum, thoroughly clean the container to prevent contaminants before mixing your pigment and concrete.
• Double-check required pigment amounts per batch by using Direct Colors’ Pigment Calculators.
• Note: Blue pigments (201, 202, and 203) use 15-20% less water than all other pigment colors
  

Caution: May be harmful if swallowed or ingested. Contact with skin can cause mild irritation. Avoid contact with eyes.

Step 2: Application

Option 1: Ready-Mix Truck

• The cement plant should load mixer with half of the total water into the empty drum.
• Add the pigment to the water and wait for a minimum of five minutes.
  • Waiting helps break down the powder
• Add aggregate, cement, sand, and remaining water while the truck is spinning.
  • Allow mixing at full speed for a minimum of 10 minutes.
• If adding pigment to the truck at the job site, allow a minimum of 30 minutes to mix at full speed.

Option 2: Mixing Drums

• Add the pigment and your concrete mix to the drum first.
  • Mix for two minutes or until thoroughly mixed.
• While spinning, slowly add water to the drum.
  • Mix for four minutes or until even color dispersion.
• If you are making multiple batches, weigh out your water for each batch to keep your colors consistent.

Option 3: Mixing Buckets

• Add a quarter of your total water and all the pigment to your bucket.
  • Mix using a drill and birdcage mixer.
• Slowly add your concrete mix to the water while continuously running the drill.
  • Gradually add more water and concrete mix to maintain workability.
• Once water is thoroughly blended, continue to mix for 3-5 minutes longer to prevent pigment streaking.

Pro Tips:

• Do not exceed 10% pigment to the weight of Portland cement in your mix.
• One pigment can produce many shades of color depending on the different amounts added to a specific concrete batch. Lower amounts of pigment produce lighter colors, while heavier loads produce deeper, richer color.
• Use a high-shear mixing tool such as a double box or birdcage mixer for buckets.
• When mixing in buckets, be sure the mixer can reach the bottom edges, where pigment can settle and lead to streaks in your finish.
• When mixing multiple batches, maintain a precise mix formula. Changes in the amount of concrete mix, pigment, or water will affect color results.

Cleanup:

• Clean tools and supplies with ProClean Degreaser™ and warm water before concrete has cured.
• Clean tools and supplies with a concrete dissolver after concrete has cured.

Tools & Supplies:
