Staining concrete can be done using various techniques and materials. Acid staining is a process of coloring concrete floors using iron oxide pigments and metallic salts mixed in a mild acid solution. The acid opens the pores in concrete and the salts react with the lime in the concrete. Since every floor is different, the reaction will vary, thus no two floors are the same. Stains can be layered using different colors to create unique two and three color floors with multiple shades and color hues. You can also create your own shades by mixing and matching your available colors or applying them at different rates.
These techniques for staining concrete floors can be used in residential homes and commercial facilities. As experienced stained concrete contractors we know the importance of properly preparing a surface and completing a beautiful job. We have completed many projects in restaurants, retail stores, office buildings, showrooms and many others locations. Stained concrete can enhance and beautify both interior and exterior concrete, old or new concrete and concrete microtoppings and overlays. Concrete staining can be a very cost effective solution to other types of flooring.
Stains and dyes can be applied to any cementitious surface including self leveling concrete and micro-toppings. They are not like paints that cover the surface. Stains and dyes blend into concrete enhancing the surface, not covering it. The combination of stains and dyes can be used to create custom floors with the appearance of natural stone, or a more vivid appearence with an artistic expression.The result is a mottled appearance. Once applied the floors can be sealed with water based or acrylic sealers, epoxies and urethanes.

Acid staining is not a dyeing or pigment-base coloring systems, but a chemical reaction. A mixture of water, mineral salts and a slight amount of muratic acid is applied to the concrete surface. This chemical reaction with the existing minerals and lime in the concrete over a period of one to four hours creates new earth tone colors on the concrete surface. The concrete surface is later scrubbed to remove excess stain and neutralized by a basic solution of ammonia and water or baking soda to help raise the ph level back to normal level. Due to inconsistencies in the surface level of concrete floor, acid staining creates a variegated or mottled appearance that is unique to each slab. The color penetration ranges from 1/16 to 1/32 of an inch.
Acid staining is guaranteed to transform a concrete slab into a luxurious floor resembling marble or glazed stone. Acid Staining offers a versatile and inexpensive flooring solution.
It will not chip, fade, or peel, and will last the lifetime of the surface to which it is applied. Those suffering from allergies find concrete staining especially appealing and a welcomed change from carpet.
Acid Stain gives concrete a mottled, variegated, marble like look. It creates beautiful colors on concrete, mostly earth tone browns, reddish browns and greens. You can also create your own shades by mixing and matching your available colors or applying them at different rates. Never expect acid stain to be uniform or have an even tone, you will get various reactions from slab to slab, and even on the same job you may see different coloration patterns.
Water Based Stains are similar to acid based stains in the sense that one can still achieve a translucent look like acid; some stains are able to achieve an opaque color and/or a translucent effect. The main difference is that acid stains react to the concrete and change the physical make up of the concrete material, whereas water based stains are more of a "coating" that bonds with the concrete. There are many variations of water based stains that have come into the decorative concrete industry that perform in a number of different ways.
Dyes or stains — what's the difference?
Basically, a concrete dye is a coloring agent, usually supplied in concentrated form, that is diluted in water or solvent (alcohol or acetone) to the desired shade. The dye may be mixed with other colors on site. It is usually applied to concrete with a pump sprayer, but may be applied with an airless sprayer, airbrush, sponge or brush, depending on the desired effect and the size of the area to be colored. The solvent or water carrier penetrates the concrete, taking the color with it. The final effect is transparent, so the concrete is visible through the color.
Chemical or acid-based reactive stains color concrete by a very different mechanism. The acid catalyzes a chemical reaction with the lime in the concrete, creating a variegated, mottled effect. Pigments in the stain impart color. Colors of reactive stains are similar to colors that occur naturally in stone, so the palette is somewhat limited.
