Even if you treat with the same staining products, no two concrete walls, countertops or floors would look the same because of factors like age and composition of concrete, as well as porosity. Property owners can DIY when it comes to concrete staining by making use of proper application techniques and tools, but we always advise hiring professionals to get that perfect finish. This is especially important if you wish to get elaborate, decorative effects by using multiple colors. The other reason we recommend hiring professionals is for safety. Working with acid based chemicals can cause skin or eye irritation because of the corrosive components contained in these stains. Stains also produce a strong odor that is difficult to inhale.
Our professionals are experts in concrete staining. Both water-based and acid-based stains can be used for many types of concrete. You can get concrete staining on interior and exterior surfaces from kitchen countertops to driveways and pool decks. If the concrete is covered by sealers, coatings, glues, grime or curing membrane, this will stop the stain from soaking, and it won’t penetrate or achieve complete color development.
Your color options vary depending on whether you use a water-based or an acid-based stain. Acid stains offer a limited selection of colors—just eight hues and most of them would be subtle earth tones such as blue greens, terracottas, tans and browns.
Customers who wish to go beyond the subdued palette can opt for water-based acrylic staining, which provides a wider spectrum of hues to choose from. There are several manufacturers offering a wide range of standard colors like metallic tints, white and black.
Selecting the right stain colors depends on personal choice or the desire to match or complement existing color schemes. Because stains are permanent, homeowners often prefer neutral tones such as greens, grays, light tans and browns. Wide variations in color are normal with acid-based stains. Surfaces would have variegated, mottled appearance and such variations would be emphasized when final coating of sealer is done.
A few acid stain colors are different when in liquid form and when they react with concrete surfaces. The true color isn’t apparent until it sets in after many hours on the concrete. We suggest applying the stain to a small test region first before covering the entire surface. The color is generally more intense on new concrete rather than older, weathered concrete. Color charts and actual samples of stained concrete are available to help you visualize options. We recommend asking professionals to show completed projects to make the best decision.
Stained concrete can be used for mimicking the look of everything from tanned leather to polished marble to stained wood and even natural stones, depending on the application technique.
Difference Between Water-Based and
Acid-based stains are generally made of inorganic metal salts that are dissolved in a water and acid solution. They penetrate into the concrete’s surface and chemically react with the concrete to form permanent bonding. The resulting color is translucent instead of opaque, leaving an attractive, rich marbling effect.
Water-based stains that are non-reactive (typically a blend of pigments and acrylic polymers) fill pores of concrete surfaces to produce colored coating or film varying from opaque to translucent depending on the product. The primary difference here is that there isn’t a chemical reaction, therefore the colors are more consistent.
Costs of Concrete Staining
There are also differences in cost. Staining costs vary depending on complexity of stain application, size of the project and surface prep requirements.
One-coat basic application of staining on concrete costs about $2 to $4 per square foot, whereas more elaborate staining tasks requiring special design skills and more time cost about $15 per square foot. The color from stains penetrate the concrete’s surface, leaving a long lasting, durable effect. When properly applied, the color won’t chip, peel or fade.
The last consideration is maintaining stained concrete. Though the stains are permanent, weather exposure can cause wear. For prolonged life, it’s important to protect the surface with a clear sealer and good floor wax.
