Poor surface preparation is the number one cause of coating failure, slippery roads and short pavement service life. Traditional manual grinding methods produce a lot of dust, leave an uneven surface texture, and slow down project progress. A floor shot blasting machine solves all these problems with its mechanical projectile and dust recovery design. Also known as a concrete blasting machine, it is a professional surface treatment equipment that shoots steel shots at high speed onto the working surface to roughen the base and remove surface residues. It comes with a matching dust collector that recycles steel shots and dust separately, so the steel shots can be reused, and the whole construction process is dust-free and pollution-free. YG provides a full range of models for different project scales, suitable for both small indoor floor projects and large outdoor road construction.
In addition to this equipment, YG manufactures and sells a range of other machinery, including concrete laser screed machines, industrial shot blasting machines, and portable dry ice cleaning machines.

Application Fields of the Floor Shot Blasting Machine
This concrete blasting machine has a wide range of applications, covering almost all common surface treatment scenarios:
- Concrete surface treatment: It can remove laitance and impurities from concrete surfaces, roughen bridge decks for waterproofing construction, clean road markings on municipal roads, and remove rubber and old lines from airport runways. It also improves surface roughness and friction coefficient to enhance road safety.
- Asphalt pavement maintenance: It cleans attachments on asphalt surfaces, roughens aged asphalt pavement, restores skid resistance, and improves road adhesion to ensure driving safety. It is also widely used for airport runway cleaning and routine maintenance.
- Steel surface derusting: It can remove rust and old paint from steel plate surfaces, reaching SA2.5 to SA3 derusting grades. It is suitable for steel structure pretreatment, bridge steel plate maintenance and other metal surface treatment projects.
- Other scenarios: Operators also apply this machine to nuclear power building decontamination, overpass coating pretreatment, railway bridge waterproofing, tunnel maintenance, workshop floor cleaning, epoxy floor pretreatment and other projects.
Floor Shot Blasting Machine Working Principle
The concrete floor shot blasting machine uses mechanical force to shoot steel abrasives at high speed and a fixed angle onto the working surface. The impact of the shots roughens the surface and removes all kinds of surface residues, including laitance, old paint, rubber marks and rust. After impacting the surface, the shots and the cleaned impurities enter the machine’s internal separation system together through the air flow of the matching dust collector. The system separates the reusable steel shots from the dust and debris automatically. The system recycles clean shots back to the storage hopper, while gathering dust and debris inside the dust tank. The whole process is fully enclosed and dust-free. It does not produce secondary pollution and protects the health of operators and the surrounding environment.


Shot Blasting VS Floor Grinding: Which Is Better For Concrete Prep?
When choosing surface preparation equipment, many contractors wonder whether to pick a shot blaster or a floor grinder. Both tools have their uses, and the right choice depends on your project needs. Here is a detailed comparison to help you decide:
1. Treatment efficiency
Floor grinding requires multiple passes to remove laitance and create roughness, and the average efficiency is about 100- 200㎡ per hour.
A concrete floor shot blasting machine can complete cleaning and roughening in one pass, with an efficiency of 300- 600㎡ per hour on concrete surfaces. For large-area projects, shot blasting can save more than half the construction time.
2. Surface uniformity
Grinding results depend heavily on the operator’s skill. Uneven pressure will leave an uneven surface, with some areas overground and some areas still with laitance left.
Shot blasting produces a completely uniform roughness across the whole surface. Every part of the floor gets the same level of treatment, which ensures consistent coating adhesion across the entire project.
3. Dust control
Dry grinding produces a lot of dust, even with a vacuum attachment. It is bad for workers’ health and pollutes the surrounding environment. Wet grinding solves the dust problem, but leaves the surface wet and requires extra drying time.
Shot blasting uses a fully enclosed dust recovery system. The whole process is almost completely dust-free, and it is a dry process so no drying time is needed. It is the most environmentally friendly option for both indoor and outdoor projects.
4. Applicable scenarios
Choose grinding if: You only do small-area projects, need to polish the floor to a very smooth finish, or work on very uneven surfaces.
Choose shot blasting if :You do medium- to large-area projects, focus on coating pretreatment or road maintenance, need high construction efficiency, or require dust-free construction.
For most professional flooring and road maintenance teams, shot blasting delivers better overall value and higher work efficiency.


6 Features of the Floor Shot Blasting Machine
- High efficiency, uniform treatment effect: It processes 300-600 square meters per hour on concrete surfaces and achieves SA2.5-SA3 grade derusting on steel surfaces. The treatment effect is uniform across the whole surface; no manual secondary repair is needed.
- Fully enclosed dust-free construction: The matching dust collector separates steel shots and dust automatically. The whole construction process produces almost no dust, which protects workers’ health and meets environmental protection requirements.
- Recyclable steel shots, low operating cost: The steel abrasives are recycled automatically inside the machine, with very low consumption. The daily operating cost is much lower than grinding equipment that requires frequent replacement of grinding discs.
- Dry process, no waiting time: It is a fully dry construction method. The treated surface is clean and dry immediately, and you can carry out the next process right away, which greatly shortens the project cycle.
- Wide range of applications: One machine can handle concrete, asphalt, steel and other surfaces. It is suitable for floor pretreatment, road maintenance, steel derusting and other projects, with high equipment utilization.
- Easy to operate and move: The machine is designed with walking wheels and a simple control panel. Workers can master the operation after simple training, and it is easy to move between different construction sites.
