What is a Pigment?
A pigment is an insoluble coloring substance, often of natural mineral or organic origin. With advancements in technology, synthetic pigments are becoming increasingly common. Pigments modify the color of the material they are added to, whether in powder or granulated form. When incorporated into concrete to achieve a specific hue, the pigment is suspended within the binder. The intensity of the color can be adjusted by varying the amount of pigment in the mix.
What is a Colorant?
A colorant is a substance—organic, mineral, or chemical—used to add color to concrete. Unlike pigments, colorants are soluble. This means they color the material at a molecular level, while pigments remain suspended between the molecules.
Pigment or Colorant?
The ultimate question: Which one should you choose? The major difference between a pigment and a colorant lies in how they interact with light:
- Colorants transmit light, creating a more vibrant or transparent effect.
- Pigments diffuse light, offering a more opaque and matte finish.
Your choice should depend on the desired effect and the specific application.
Durability of Pigments and Colorants
Both pigments and colorants are designed to withstand harsh conditions, including prolonged sun exposure and weather extremes. Thanks to their high resilience, they are suitable for almost all indoor and outdoor applications.
3 Tips for Successful Concrete Coloring
- Test First: Prepare samples to experiment with colors and avoid waste.
- Mix Well: Ensure a homogeneous blend for a uniform finish.
- Use the Right Tools: Proper tools are crucial for both application and finishing to achieve the desired result.
