How to color concrete home improvement projects can be done easily and add value to your property. No one likes grey or dull concrete and adding some color to the concrete that you’re pouring adds a custom feel to your project. This can make the concrete more aesthetically pleasing and can help bring together the look of your project.
How to color concrete can be done with a small variety of color or dye with a limited palette of several colors. Because the cement is unkind, some pigments that work well in paint media are bothered by the causticity, resulting in color degeneration over time. To be certain, you must use pigments that have been approved to be used when mixed with concrete.
The most typical concrete colors are earth tones. For example, rust red or yellow, brown, charcoal. Green is less common and more expensive. Blue is even more expensive because it is very uncommon. Most colors seem to be derived from iron oxide or cobalt that are found in nature.
Colors typically come in the form of a powder. The powder is commonly mixed with water to form a paste. Adding color to concrete can add value and luster to your property but be careful on how much color to use. Getting a deep color can be a challenge because the pigments have a maximum use percentage typically in and around 10-15% of the total concrete mix. If too much paste is used, you can weaken your concrete and have a nice rich color. If you use too little, you will have a strong batch of concrete, but a light color.
One way to counter act this drawback is to mix and pour a strong batch on concrete with out any color and use it as a foundation. Then, mix a colored batch to be placed on top of the strong batch. This will ensure you get a nice and strong foundation of concrete with a rich and deep surface color.
Another method on how to color concrete is to use acid stains. They function by being applied on the surface of the concrete. The acid creates pours in the concrete enabling the stain to penetrate the concrete. These are very effective and are permanent. Keep in mind that concrete stain is similar to wood stain in that it can actually highlight and exaggerate the flaws found in the concrete. This includes natural as well as man-made blemishes and markings. So beware!
