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.
