In January 2026, a leading industrial flooring contractor in Busan, South Korea, implemented a concrete floor shot blasting machine from YG Machinery to improve concrete surface preparation efficiency. The client reported that the machine reduced labor costs by 35% while maintaining consistent surface quality, making it a critical upgrade for large-scale warehouse and factory projects. The machine is designed for heavy-duty industrial floors, capable of removing old coatings, leveling rough surfaces, and preparing the base for epoxy or anti-slip coatings.
Client Challenges and Needs
Before adopting the machine, the client faced several common issues:
- Manual grinding and sandblasting were slow and inconsistent, especially on floors larger than 2,000 m².
- Surfaces often retained residual paint and uneven concrete, affecting coating adhesion.
- Labor costs were rising, and compliance with safety standards for dust control became more stringent.
The client required a solution that could deliver:
- Uniform surface roughness for coating application
- High coverage area with minimal downtime
- Efficient dust collection to meet environmental regulations

Industry Context in South Korea
Industrial contractors in South Korea increasingly adopt automated floor preparation solutions due to:
- Growing demand for high-quality epoxy and protective coatings
- Rising labor costs for manual grinding and sandblasting
- Regulatory pressure on dust control and environmental compliance
Concrete floors in warehouses, factories, and parking structures often need resurfacing or coating preparation. Many projects face delays due to inconsistent surface preparation and equipment limitations.
YG’s Solution
YG Machinery addressed these challenges by supplying a floor shot blaster for sale optimized for Korean industrial floors. Key solutions included:
- Adjustable working width to handle tight and open spaces efficiently
- Integrated dust collection system to reduce airborne particulates
- Durable steel construction for continuous operation in industrial environments
- Easy maintenance with replaceable blast wheels and conveyor belts
After deployment, the client reported:
- Surface preparation speed increased by 50% compared with previous methods
- Consistent surface roughness improved coating adhesion and reduced repainting cycles
- Shot blasting concrete cost decreased by 20% per m² due to higher productivity and lower labor requirements
Client Feedback
The site manager commented:
“The YG concrete floor shot blasting machine transformed our workflow. Large floors that previously took two days now take less than one day, and the surface quality is consistently excellent. The dust control system also keeps our workspace safe.”
This feedback highlights the machine’s practical benefits and aligns with typical needs of other South Korean contractors.
