Known for its high efficiency, dust-free operation, and environmental friendliness, this machine plays a critical role in a wide range of applications, from road maintenance to warehouse renovations.
What is a Floor Shot Blaster?
A floor shot blaster is a surface preparation machine that uses high-speed steel shots propelled by a rapidly rotating blast wheel. The shots impact the surface with force, removing contaminants such as old coatings, paint, rust, adhesives, and laitance, while also roughening the surface to improve adhesion for new coatings or overlays.
This process is completely mechanical—no water or chemicals are needed—making it ideal for eco-friendly and dry applications.
Key Benefits of Floor Shot Blasting
- High Efficiency
Floor shot blasters cover large areas quickly, making them ideal for commercial and industrial projects. Some models can treat hundreds of square meters per hour. - Consistent Surface Profile
The shot blasting process creates a uniform surface texture, which is crucial for bonding epoxy, polyurethane, or other coatings. - Dust-Free Operation
Most floor shot blasters come equipped with an integrated dust collector or vacuum system, keeping the worksite clean and safe. - Eco-Friendly
As a dry, chemical-free process, shot blasting is safer for workers and more environmentally responsible compared to acid etching or solvent-based methods.
Common Applications
- Concrete floor preparation before coating or painting
- Steel floor and deck cleaning in shipyards or industrial plants
- Removal of old coatings, lines, adhesives, and contamination
- Anti-slip surface preparation for public walkways or parking garages

How It Works
The floor shot blaster propels steel shots at high velocity onto the floor surface. The rebound and debris are collected and separated; reusable steel shots are recycled back into the system, while dust and waste are filtered and collected. This closed-loop system ensures minimal waste and maximized productivity.
Choosing the Right Floor Shot Blaster
When selecting a floor shot blaster, consider the following:
- Working width – Determines how much area the machine can cover in one pass
- Power source – Electric or diesel-powered options are available
- Dust collection system – A strong vacuum system ensures dust-free operation
- Portability – Compact models are ideal for confined spaces or small job sites
