Decorative Concrete - Concrete Dyes

Concrete Dyes

Concrete "dyes" take many different forms and compositions and can be used on both residential and commercial concrete applications, including sound/retaining walls, bridges, countertops, floors, etc.

Early concrete dyes consisted of generic printing inks that were dissolved in mild solutions of alcohol and applied to concrete surfaces to add a wide array of color to plain gray concrete. When alcohol-based dyes are exposed to sunlight, the color either lightens or fades out completely. Therefore, alcohol-based dyes were more prevalent in interior applications where direct sunlight or other forms of ultraviolet (UV) lighting was not present.

Manufacturers later began dissolving the same printing inks in different carriers, such as acetone, lacquer thinner and other solvents, hoping to achieve increased penetration levels. In addition, UV inhibiting agents were added to new dyes to help with the UV instability issues. However, slight fading (5-8% per year) still occurs when the dye is exposed to direct sunlight.

Colored concrete can be obtained from many ready mix concrete companies and many have color charts available.

Famous quotes containing the word concrete:

    Babies are necessary to grown-ups. A new baby is like the beginning of all things—wonder, hope, a dream of possibilities. In a world that is cutting down its trees to build highways, losing its earth to concrete ... babies are almost the only remaining link with nature, with the natural world of living things from which we spring.
    Eda Le Shan (b. 1922)
