In August 2025, a German contractor purchased a floor shot blasting machine from YG Machinery for an underground parking garage renovation project. The project required efficient concrete floor surface preparation, including cleaning old coatings, removing contaminants, and improving surface roughness for new epoxy flooring installation.
This case demonstrates how a properly selected concrete floor shot blasting machine can significantly improve construction efficiency and surface quality in real industrial applications.

🇩🇪 Project Background – Underground Parking Garage Renovation
The customer from Germany was working on a medium-sized underground parking facility that had been in use for many years. The concrete surface showed:
- Oil stains and tire marks
- Weak and dusty surface layer (laitance)
- Uneven surface profile
- Poor adhesion for new coating system
The contractor needed a reliable solution for bead blasting concrete floors to prepare the surface for epoxy coating installation.
They searched for equipment such as:
- shot blasting machine for concrete
- concrete sandblasting machine
- cement shot blaster
- concrete floor blaster
Finally, they contacted YG Machinery for a professional solution.
Customer Requirement – What the Client Needed
The German customer required a machine that could:
- Efficiently clean large concrete surfaces
- Provide uniform surface roughness
- Work in confined underground spaces
- Reduce labor cost and project time
- Deliver stable performance for continuous operation
They also compared the shot blasting concrete cost with traditional grinding methods and found shot blasting to be more cost-effective for long-term use.
YG Solution – YG270 vs YG550 Recommendation
After technical evaluation, YG Machinery recommended two models:
✔ YG270 Floor Shot Blasting Machine
- Compact design for medium-sized projects
- Suitable for underground parking garages
- Easy to operate in narrow spaces
- Ideal balance between efficiency and mobility
✔ YG550 Floor Shot Blasting Machine
- Higher capacity for large industrial floors
- Wider working width
- More suitable for open-area projects
After comparing both options, the customer finally chose the YG270 floor shot blasting machine, as it perfectly matched the working space of the underground parking garage.
👉 This decision helped optimize both cost and operational flexibility.
On-Site Application – Concrete Floor Surface Preparation
Once the machine arrived in Germany, the customer immediately started the project using the floor blasting machine.
The process included:
- Removing old surface layers and contaminants
- Performing bead blasting concrete floors to create uniform roughness
- Preparing the surface for epoxy coating adhesion
The concrete floor shot blasting machine worked efficiently, and the operator reported that:
- The surface was cleaned in a single pass
- Dust collection system kept the working environment clean
- The machine was easy to control in confined underground space
Compared with manual grinding, the concrete blasting machine significantly improved productivity and reduced labor intensity.
Project Result – Excellent Performance Feedback
After completion of the project, the results were highly satisfactory:
- The floor surface became clean and uniformly rough
- Epoxy coating adhesion was significantly improved
- Construction time was reduced compared to traditional methods
- Overall cost to shot blast concrete floor was lower than expected
The client confirmed that the floor shot blaster for sale (YG270) performed reliably and efficiently throughout the project.
They also mentioned that they previously used grinding methods, but the bead blaster floor machine provided much better consistency and faster output.
Customer Feedback
The German contractor gave positive feedback:
- Stable performance during continuous operation
- Excellent surface preparation quality
- Easy maintenance and operation
- Highly suitable for underground parking projects
They stated that they would consider purchasing additional equipment from YG Machinery for future projects involving sandblasting concrete floors and industrial surface treatment.
Conclusion – Why This Case Matters?
This project in Germany clearly shows that the floor shot blasting machine is an efficient solution for:
- Underground parking garages
- Industrial floor renovation
- Concrete surface preparation projects
- Epoxy coating base treatment
Whether it is shot blasting machine for concrete, cement shot blaster, or concrete floor blaster, selecting the right model (like YG270) ensures better efficiency, lower cost, and higher surface quality.
