Concrete Staining
Staining concrete is one of the most popular applications for transforming the unattractive standard gray surface of concrete. Designers, homeowners, and builders are increasingly drawn to stained concrete because of the unique outcome that can be achieved through the combination of color, techniques, and general creativity.
Because of the porous qualities and neutral tone of concrete, it is the perfect building material surface to provide structural reliability without sacrificing style. Using acid-based chemical stains, most concrete surfaces can be transformed into rich, earth-toned color schemes resembling natural stone, marble, wood, or even leather, providing a custom look that compliments your driveway, patio, walkways, pool deck, or concrete walls.
Acid stains are a mixture of water, hydrochloric acid, and acid-soluble metallic salts. Due to the chemical reaction that results on application, it becomes a permanent part of the concrete and won't fade, chip off, or peel away. Like wood stains, concrete stains are translucent and the resulting color may vary slightly depending on the color and condition of the concrete on which they are applied. Acid stains don't offer a broad color selection. Colors most commonly available are subtle earth tones such as tans, browns, terra cottas, and soft blue-greens. Newer stains are being developed that are quickly expanding upon this limited palette.
If you are pouring new concrete and wish to stain or have it colored, there is a process of coloring that can be performed after the concrete has just been poured. This method can saturate your color of choice to a depth of 1/8 inch or more. This method offers an unlimited palette of colors from which to choose.
Beware of do it yourself products available at the home improvement store that claim to be stains but are actually a film application. These products will not last as long or look as good as a legitimate concrete stain.
While there are some products available to DIY experts that are helpful for smaller jobs, we strongly recommend contracting a professional for larger ones. Remember, it's concrete, and most application mistakes are permanant.
