Colored Concrete 04/21/2011
 
Concrete is one of the most commonly used man-made materials, its made by mixing an aggregate with a cement binder – often Portland cement, mineral aggregates and water. Concrete has a rather low tensile strength, but a very high compressive strength.

Surprisingly, you can stain and color concrete based on your preference and decorative scheme. Coloring adds beauty and strength to concrete walls; it is a cost-effective way to add color and enhance the look of your home and yard. The color choices for concrete are varied and the finishes are limited only by your imagination. Sandblasting colored concrete will give your concrete a very dramatic look!

You can color concrete in a variety of ways: acid staining, painting and using integral color. Integrally colored concrete can be done either on site or with colored bags. Usually, the outcome is earthy or pastel and the colorant can be either a liquid or powdered form.

Brighter colors usually require a “Dry Shake.” This method makes concrete even more durable and abrasive-resistant. Dry shaking colors the surface of the concrete and can be used to beautifully break-up the mono-color of large areas of concrete.

You can get very cool effects by using multiple colors. This is easy to do at home and you should be able to find ready-mix bags at a landscape supply store.

Color uniformity is achieved by carefully preparing materials and observing proper curing of the concrete. Your cement-water ratio must remain consistent throughout to ensure that the colors are even. After coloring the concrete, a sealer is used to protect the finish and improve its ability to withstand weather and water. Most colors for concrete are lime-proof. Colored concrete is beautiful on driveways, patios and walkways.
