Concrete, one of the most commonly used man-made materials, is 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.
