A floor shot blasting machine may suit your project if you need to remove surface residues, improve concrete texture, or prepare steel for coating. However, the right choice depends on the material, its condition, and your required finish. A machine that works well on a concrete floor may need different settings for steel or asphalt.
YG Machinery offers YG-270, YG-550/600, and YG-850 configurations. Their working widths range from 270 mm to 800 mm. Before choosing a model, check the surface condition, working area, and required cleaning result.

Is a Floor Shot Blasting Machine Suitable for Concrete Floors?
Material / Condition: Industrial concrete floors, concrete pavement, and surfaces with laitance or light residues.
Recommendation: Suitable
Concrete is a primary application for this equipment. Steel shots strike the surface at high speed, removing loose material and creating a rougher profile. This treatment can help prepare concrete for suitable coatings, waterproofing systems, or other follow-up work.
Required Configuration: Choose the working width according to the available space and required output.
Actual output depends on concrete strength, surface condition, blasting settings, and the required finish.
Important Limitation: The floor should be relatively dry and free of standing water. Surface unevenness should remain below 10 mm. Very weak concrete may suffer excessive material removal or damage, so test a small area first.
Can a Floor Shot Blasting Machine Treat Asphalt Pavement?
Material / Condition: Asphalt roads requiring surface cleaning, texture improvement, or preparation for selected maintenance work.
Recommendation: Suitable with the right configuration
Shot blasting can remove certain surface residues and change pavement texture. It may also support selected road maintenance and friction-improvement projects. However, asphalt varies in hardness, aggregate condition, and binder content.
Required Configuration: Confirm the asphalt condition, target surface profile, shot size, and machine settings. Start with a small test section before treating a large area.
Important Limitation: Shot blasting is not suitable for every asphalt surface. Weak, deteriorated, or loose asphalt may experience aggregate loss or surface damage. Do not assume that every road needs blasting before repair, marking, or resurfacing.
For larger road projects, compare the treatment requirements with those of a road roller. The two machines serve different purposes: one treats the surface, while the other compacts suitable materials.
Is Shot Blasting Suitable for Steel Plates?
Material / Condition: Steel plates and other compatible steel surfaces requiring rust removal or preparation before coating.
Recommendation: Suitable with the right configuration
Steel shot blasting can remove rust, scale, and certain contaminants. It can also create a surface profile for compatible coating systems. Your required cleanliness grade and coating specification should determine the treatment settings.
Required Configuration: The supplied specifications list steel surface cleaning efficiencies of 15–25 m²/h for YG-270, 75–100 m²/h for YG-550/600, and 100–160 m²/h for YG-850. Select the model according to the required output and surface condition.
For steel work, check the abrasive size and dust collection arrangement. The equipment must also suit the workpiece dimensions and site layout.
Important Limitation: The steel must be dry, and its surface temperature should be at least 3°C above the dew point. Relative humidity during steel blasting should not exceed 90%, according to the supplied operating requirements. Confirm the required cleanliness grade before production.
Can a Floor Shot Blaster Prepare Bridge Decks?
Material / Condition: Concrete bridge decks, railway bridge surfaces, and other compatible concrete structures requiring surface preparation.
Recommendation: Suitable with the right configuration
Bridge deck preparation may require removing weak surface material, improving texture, or preparing concrete for a waterproofing system. Shot blasting can support these tasks when the structure and treatment specification permit it.
Required Configuration: Match the working width to the available work area. Confirm access, surface strength, dust collection, and the required profile with the project engineer. A narrower machine may offer better control in restricted areas, while wider equipment may improve coverage on open surfaces.
Important Limitation: Bridge decks require careful control of surface removal and cleanliness. Do not use blasting as a substitute for structural repair. Follow the specified preparation standard for the waterproofing or coating system, and verify the result before proceeding.
Can It Remove Old Road Markings and Coatings?
Material / Condition: Concrete pavement, selected road surfaces, and compatible areas with old markings or surface coatings.
Recommendation: Suitable with the right configuration
Shot blasting can remove certain coatings and road marking materials while changing the underlying surface texture. It may be useful during road maintenance or when preparing a surface for a new treatment.
Required Configuration: Confirm the marking material, coating thickness, substrate condition, and required removal depth. Use a test area to establish suitable settings before full-scale work.
Important Limitation: Thick or elastic markings may require a different removal method. Blasting may also affect the underlying pavement. For road marking projects, confirm the surface preparation requirements before selecting the equipment.

| Concrete pavement | Suitable | Surface condition and removal depth |
| Asphalt pavement | Suitable with the right configuration | Aggregate stability and binder condition |
| Steel plates | Suitable with the right configuration | Rust level, cleanliness grade, and humidity |
| Concrete bridge decks | Suitable with the right configuration | Structural condition and project specifications |
| Old road markings and coatings | Suitable with the right configuration | Coating type, thickness, and substrate |
| Wet surfaces or standing water | Not recommended | Dry the surface before operation |
| Severely deteriorated or loose substrates | Not recommended without assessment | Repair or test the substrate first |
| Rainy or snowy operating conditions | Not recommended | Wait for suitable operating conditions |
How Should You Choose the Right Model?
YG-270 has a 270 mm working width and suits projects where a narrower working path is useful. YG-550/600 offers a 550 or 600 mm working width, while YG-850 provides an 800 mm working width for wider coverage. Actual productivity depends on the material, required finish, and operating conditions.
When comparing a concrete shot blasting machine with other surface preparation methods, focus on the required surface profile, removal depth, working area, and dust collection needs. No single method suits every substrate or project.
