Usage
Directions: Step 1: The truck mixer drum must be completely clean with no leftover water or aggregate before mixing a new batch of colored concrete. Step 2: The slump must range from 3 ½” to 4”. If air is entrained, it should range from 5% to 7%. Step 3: Before adding the bags of pigment, reverse the truck mixer to bring the concrete to the back of the mixer. Step 4: Place half the bags of color on top of the concrete. Please Note: Steps 5 & 6 are critical for proper dispersion. Step 5: Slowly move the concrete back to the front of the mixer, and start mixing at a slow speed until the bags are drawn into the concrete mix. Mix slowly for 2-3 minutes. Step 6: Increase the speed of the mixer to a medium-high rotation for 2-3 minutes. Step 7:Reverse the mixer to bring the concrete to the back of the mixer and add the remainder of the color bags. Step 8: Repeat steps 5 & 6 with the other half of the bags. Step 9: Move the concrete mix from the front to the back of the mixer 3 or 4 times to pick up any pigment and concrete that may not have been incorporated into the mix. Step 10: Mix for a total of 10 to 15 minutes at regular mixing speed. Step 11: Always place the first concrete down the chute of each load on the bottom of the slab.

Note: For complete details, please refer to our Instruction Sheet on Ready-Mix Colors.

Limitations: The optimal dosage of pigment suggested varies between 2% and 7%, based on the total weight of cementitious materials. A dosage of 10% of pigment based on the total weight of cementitious materials is the saturation point for pigment coloration. If the percentage of pigment is over 10% of the total weight of cementitious materials, there will be no benefits and it can affect the results considerably. In addition, if the percentage is lower than 1% of the total weight of cementitious materials, the coloration will be uneven and will affect the results.

Safety
Refer to material safety data sheet of the color desired.

Technical Services
The Interstar Color Laboratory is available to match existing colored concrete, develop special color tones or to provide expert color assistance to solve your individual color needs. Please contact Interstar Color Laboratory for assistance. Since the color shades of cement and aggregates (coarse and fine) are different in each locality, it is recommended to send 10 lbs of the local cement and 25 lbs of the coarse and fine aggregate that will be used in the concrete mix design, along with a sample of the desired color that is to be produced.

Samples: Samples of Interstar standard Concentrated Concrete Colors and specially blended colors are available in convenient cement color briquette form or mini-pavers. The color block samples are mixed in the Interstar Laboratory with locally supplied cement and aggregates, or with cement and aggregates available to Interstar at the time of production.
