    Concrete Etching Machine Solutions for Award-Winning Precast Finishes

    When it comes to achieving a superior finish on architectural precast concrete, there’s no match for acid etching. And when it comes to acid etching, Kem-O-Kleen stands out as the leading concrete etching machine trusted by professionals across the country.

    More than 70% of the nation’s largest architectural precast manufacturers and FRC (Fiber Reinforced Concrete) facilities rely on our concrete etching machines for unmatched results. With repeat customers, multi-unit installations, and decades of specialized expertise, our systems are designed to deliver fast, consistent, and efficient results.

    Why Choose a Kem-O-Kleen Concrete Etching Machine?

    Kem-O-Kleen’s concrete etching machines are engineered specifically for acid etching applications in precast concrete environments. Here’s why so many professionals trust our equipment:

    • Cut etching time in half compared to manual or outdated methods

    • Consistent, thorough coverage—especially in intricate details where traditional acid application can miss

    • Lower chemical usage—our machines are optimized for muriatic acid

    • Superior surface finish—reveals natural aggregate without dulling as sandblasting does

    • Precision chemical control—adjust and apply acid efficiently and evenly

    • Heavy-duty construction—built to endure rugged job site conditions

    • 200 feet of full-jacket hose—covers large areas without repositioning

    • Multiple models—suitable for high-volume operators and small ornamental shops alike

    Choosing the Right Model for Your Needs

    Our lineup of concrete etching machines includes systems for every type of precast operation:

    • MK7 and SK8: High-powered models designed for fast-paced, large-scale production

    • MK3 and SK4: Ideal for smaller plants, ornamental work, or FRC panels needing precise etching without overpowering output

    No matter the size of your operation, there’s a concrete etching machine designed to improve your process and finish.

    What is Acid Etching in Concrete?

    Concrete etching machines play a key role in acid etching, which is a technique used to achieve beautiful finishes on precast concrete. This process involves applying a diluted hydrochloric acid (or KOH) solution to the surface to remove the top cement paste and expose the aggregate underneath. The result is a uniform, textured finish resembling limestone or sandstone.

    Acid etching is typically used on panels with light to medium exposure. Unlike untreated or sandblasted surfaces, acid-etched concrete provides a cleaner look while enhancing weather resistance.

    Benefits of Using a Concrete Etching Machine

    Using a concrete etching machine streamlines the acid application process. Benefits include:

    • Faster turnaround: Etching can be done soon after demolding
    • Better durability: Acid-etched surfaces help concrete resist weathering and salt infiltration
    • Natural appearance: Acid-etched panels align with modern architectural trends
    • Improved consistency: Machines ensure all panels are etched uniformly, regardless of volume

    When precast elements are etched using KOH shortly after being removed from molds, they better resist chloride intrusion and maintain structural integrity longer. For best results, it’s important to etch panels around the same time post-mold removal.

    Trusted Nationwide by Precast Leaders

    From reducing production time to enhancing final aesthetics, our concrete etching machines have supported the success of award-winning projects across the country. Whether you’re scaling up or refining your finish, Unique Industries and Kem-O-Kleen provide proven solutions that elevate every panel.
