The Rising Popularity of Acid Stained Concrete

Acid stained concrete is growing in popularity. But concrete stains are different than paints and sealers. Their uses are different, and their long-term effects are different. What to use for what job? Ah, that is the question.

Acid stains react chemically with the concrete, as opposed to dying, as some pigmented stains do. The acid dissolves cement particles and reacts to hydrated lime, creating colored compounds. Water from the stain helps the reaction, which completes the acid stained concrete process in approximately one month.

Stained Concrete

Acid stained concrete can look artistically pleasing, the stain forming interesting color variations from the process. The final colors are somewhat unpredictable, but basically end up being different variations of black, brown, and blue-green. Hue and value depend mostly on the stained concrete’s chemical make-up.

Although fairly costly, acid stained concrete can last several years, and the staining can be applied to any concrete surface, whether existing, or freshly laid. It can be applied to overlays and vertical surfaces as well, making the concept versatile. An artistic value of acid stained concrete is its ability to become a custom job, allowing for creativity and signature style.

Sealers, on the other hand, are designed more for elemental and chemical protection, and work with the existing concrete, sealing gaps and adding solidity. They are more functionally versatile, able to work on exterior surfaces as well. Acid stained concrete is sealable, but mainly functional with interior surfaces.

Function, protection, beauty, and longevity are all vital components in concrete maintenance. For acid stained concrete, all four are in the eyes of the beholder.
