When renovating industrial floors, warehouses, parking lots, and airport runways, the first step isn’t laying new materials, but thoroughly cleaning the old surface. Applying epoxy flooring directly will result in peeling after drying; painting directly will flake off after a few months. The reason is simple—if the surface isn’t clean, nothing will adhere. Concrete shot blasting machines are the core equipment for modern industrial floor surface treatment. Using a high-speed rotating shot blasting wheel, steel shot is accelerated to 80m/s, physically removing laitance, old coatings, oil, and impurities from the concrete surface, providing an ideal base for subsequent epoxy flooring, polyurethane coatings, or anti-slip treatments. This highly efficient surface preparation equipment is widely used in floor treatment projects for industrial plants, parking lots, airport runways, bridges, and tunnels. As a professional surface treatment equipment manufacturer, YG’s shot blasting machines are renowned for their high efficiency, durability, and ease of maintenance, earning the trust of customers worldwide.

YG’s Road Surface Shot Blasting Machine: Core Functions and Technical Features
- High-Efficiency Surface Treatment Capability: Concrete shot blasting machines can complete the cleaning of large areas of ground in a short time. Compared to traditional manual grinding methods, the efficiency of grit blasting is 5-10 times higher. A standard model can process 200-400 square meters of ground per hour, significantly shortening the construction cycle and reducing labor costs.
- Uniform and Consistent Treatment Results: The machine’s travel speed and blasting volume can be precisely adjusted to ensure a uniform roughness across the entire work surface. This repeatable surface treatment quality is crucial for industrial flooring projects that require strict control of coating adhesion.
- Deep Cleaning Capability: Shot blasting thoroughly removes cement slurry, oil, release agents, and aged coatings from concrete surfaces. For surfaces requiring epoxy or polyurethane coatings, the shot-blasted surface provides optimal mechanical anchoring, significantly improving the bond strength between the coating and the substrate.
- Environmentally Friendly and Dust-Free Operation. The accompanying dust removal system adopts a closed-loop design, ensuring that dust generated during operation is immediately sucked into the dust collection box, and the emission concentration meets national environmental protection standards. Operators do not need to work in a dust-filled environment, effectively protecting their occupational health.
- Steel Grit Recycling System. High-quality steel grit achieves a recovery rate of over 95% in the separation system and can be reused dozens of times. This significantly reduces the abrasive cost per application, making sandblasting more economical than shot blasting with disposable abrasives.
- Flexible Operation. Adjustable travel speed and a flexible chassis design allow the equipment to adapt to various complex construction environments. It can efficiently complete operations in both large workshops and narrow corridors.

- Road and bridge projects: Pre-treatment for bridge waterproofing, roughening of road surfaces for anti-slip purposes, removal of rubber residue from airport runways, and removal of highway markings, improving road surface roughness and anti-slip properties.
- Commercial and public spaces: Renovation of shopping mall, supermarket, and hotel lobby floors, removing old coatings and stains to create a uniformly rough surface suitable for subsequent polishing and epoxy finishing.
- Port and dock projects: Rust removal, desalination, and removal of marine organisms from dock concrete surfaces, improving the adhesion of anti-corrosion coatings, and extending structural lifespan.
- Water conservancy and tunnel projects: Cleaning and roughening of concrete surfaces in reservoirs, dams, and tunnels to remove laitance, cracks, and impurities, providing pre-treatment for waterproofing and seepage prevention coatings.
- Precast Components for Prefabricated Buildings. Roughening the surface of precast concrete slabs and wall panels improves adhesion at joints and enhances structural integrity.
- Renovation of Old Buildings. Renovation of concrete walls/floors in old houses and office buildings, removing old paint, putty, and oil stains without large-scale demolition, saving costs.
- Stone Surface Treatment. Anti-slip roughening and antique finishes on marble, granite, and concrete brick surfaces enhance decorative effect and wear resistance.
How to Choose the Right Shot Blasting Machine Model Based on the Construction Area?
- The construction area is the primary consideration. For projects smaller than 1000 square meters, a lightweight model with a 270mm working width is sufficient, offering flexibility and ease of relocation. For areas between 1000 and 5000 square meters, a medium-sized model with a 550mm working width is more efficient, capable of handling over 1000 square meters per day. For large projects exceeding 5000 square meters, a large model with a width of 850mm or more is recommended, enabling large-scale construction through a fleet of machines.
- Ground hardness affects equipment selection. Freshly poured concrete has lower hardness, so a standard model is sufficient; however, older ground or high-strength concrete may require more powerful equipment.
- The working environment is also an important factor. Enclosed indoor spaces require more robust dust collection systems; open outdoor areas allow for mobile equipment, improving relocation efficiency.
- Budget constraints should not be overlooked. It is recommended to choose equipment that meets basic needs within the budget, without excessively pursuing high power and high configuration. Upgrades can be made gradually as business needs develop.
