- Provide protection against wear, UV exposure, and environmental factors
- Can create unique, variegated effects
What are the different ways of coloring concrete?
Concrete can be colored in four different ways: stains, integral pigments, color hardeners, and dyes.
- Stains penetrate the surface for a translucent color that highlights the concrete’s texture.
- Integral pigments are mixed into the batch for uniform color, ideal for large areas.
- Color hardeners are applied before finishing, enhancing both color and durability for high-traffic zones.
- Dyes offer vibrant hues for decorative purposes and can be used on both new and existing concrete for intricate designs.
Stains
Stains are liquid solutions that penetrate the concrete surface, providing a translucent color that enhances the material’s natural texture. They are ideal for both new and existing concrete surfaces, allowing for creative designs and effects, such as marbling or blending multiple colors for depth.
Stains can be used on a variety of concrete applications, including driveways, patios, walkways, floors, and decorative features. They are particularly effective for projects where a unique, artistic finish is desired, as they can create visually appealing effects that highlight the concrete’s texture. Stains are suitable for both interior and exterior surfaces, making them versatile for residential and commercial applications.
There are two primary types of stains: acid-based stains, which react chemically with the concrete to produce rich, variegated shades, and water-based stains, which offer a broader range of vibrant colors and are easier to apply.
The cost of stains varies based on the type and brand, typically ranging from $0.50 to $3.00 per square foot, making them a cost-effective option for adding color to concrete.
