What is Concrete Etching?Concrete etching is the term used to describe the process of applying acid to etch or wash a piece of concrete. The acid allows the concrete's pores to open and makes them easier to treat. | | By ProMatcher Staff | | Updated: 06/18/2018 | | | The process of concrete etching occurs when you take acid and pour it over a slab of concrete. The acid is applied to open the pores of the concrete, thereby making the concrete easier to treat with a sealant or other protective material. This process is much easier than other methods of preparing concrete and much less labor-intensive.
