Von Arx Concrete Shot Blasters – Professional Preparation of Industrial Surfaces

Von Arx shot blasters are modern, mobile machines for mechanical preparation of concrete, asphalt and steel. Shot blasting technology is based on the intensive impact of steel shot against the substrate surface. A high-energy abrasive stream effectively removes cement laitance, resin coatings, paints, industrial contaminants and worn surface layers.

The rebounded shot together with removed material enters a closed separation system, where heavy abrasive is recycled and light contaminants are directed to an industrial vacuum. Thanks to the closed-loop system, the Von Arx shot blaster together with a Von Arx shot blasting vacuum ensures dust-free, environmentally friendly and efficient surface preparation.

Why is concrete shot blasting so effective?

Shot blasting:

• removes cement laitance from fresh concrete,
• cleans old, long-term contamination,
• removes resins, paints and industrial coatings,
• roughens and profiles the surface (CSP),
• opens concrete pores and exposes cracks and weak points,
• prepares the surface for epoxy and polyurethane systems.

Properly prepared concrete flooring ensures maximum adhesion of resin systems and insulation materials, which directly impacts the durability of the entire project.

Steel Shot Blasting – Cleanliness Level SA 2.5

Von Arx shot blasters also enable cleaning of steel surfaces to cleanliness grade SA 2.5 while creating the proper roughness for anti-corrosion coatings. This is crucial in industrial structures, bridges and the marine industry.

Applications of Von Arx Shot Blasters

Shot blasting technology is used in:

• industrial halls and warehouses,
• parking lots and underground garages,
• bridges and viaducts,
• logistics facilities,
• ship decks and steel structures,
• flooring and renovation works.
