Dark acid washed concrete Acid washed concrete is a popular technique to give concrete surfaces a unique and attractive appearance. This process uses acid like our Surfkoat Surf-Prep to etch the surface of the concrete, removing a thin layer of the top layer of concrete, and exposing the aggregate underneath. This creates a textured, mottled appearance that can be customized with a variety of colors and finishes.

How Do You Create Acid Washed Concrete?

Applying acid wash to concrete surfaces requires careful preparation and execution to achieve the desired result.
  • The surface must be thoroughly cleaned and prepped, and any cracks or imperfections must be repaired prior to applying the acid wash.
  • A solution of acid and water is then applied to the surface using a sprayer or roller. The acid reacts with the minerals in the concrete, creating a chemical reaction that etches the surface and removes a thin layer of the top layer of the concrete.
  • Once the acid wash has been applied, the surface must be neutralized with a solution of baking soda and water to stop the chemical reaction.
  • The surface is then rinsed thoroughly with water to remove any remaining residue.
  • Once the surface has dried, a sealer is applied to protect the surface and enhance its appearance.

What Are the Benefits of Acid Washed Concrete?

There are many benefits to acid washed concrete, three of which include:


The etching process creates a surface that is resistant to staining and damage from heavy foot traffic or vehicular traffic. It is also low maintenance, requiring only periodic cleaning with mild detergent and water to keep its appearance looking great.

Highly Customizable

The etching process creates a textured, mottled appearance that can be further customized with various colors and finishes. Stenciling, scoring, and other decorative techniques can be used to create unique patterns and designs that enhance the appearance of the surface.


Because it is made from locally sourced materials and requires minimal maintenance, it has a lower environmental impact than other flooring materials. Additionally, the use of acid wash can help to reduce the amount of waste generated during construction and renovation projects by revitalizing existing concrete surfaces.
