Floor shot blasting machine is a professional surface preparation equipment that uses high-speed steel shots to impact the ground surface for cleaning, roughening, and removing contaminants. It operates by propelling steel shots through a high-speed blasting wheel, hitting the floor, and then recycling the shots for continuous use.
This machine is widely used on concrete floors, steel plates, and asphalt pavements. It provides a dust-free, efficient, and environmentally friendly method for surface treatment, and is considered one of the most reliable solutions before applying coatings or waterproof systems.
Detailed Introduction To The Main Uses And Applications
As an important surface preparation equipment, the floor shot blasting machine is widely used in many industrial and construction fields. In engineering practice, this machine uses high-speed steel shots impacting the ground surface to remove contaminants and create a uniform roughness. The whole process is dust-free and environmentally friendly, making it a preferred solution for modern flooring engineering.
1. Concrete Surface Preparation Before Coating
In floor coating projects, surface preparation is always a critical step. A floor shot blasting machine can efficiently remove laitance, weak layers, dust, and contaminants on concrete surfaces.
This helps the coating materials such as epoxy, polyurethane, and polyurea to achieve better mechanical bonding.
In our engineering projects, using shot blasting usually increases coating adhesion by 30–50%.
2. Removal of Old Coating, Paint, and Markings
For renovation projects, the machine is also used to remove old coatings or traffic markings.
Compared with traditional grinding, shot blasting has higher cleaning depth and uniformity, and it does not burn the surface.
Therefore, it is widely applied in:
- Old epoxy workshop floors
- Parking lot line removal
- Warehouse coating renovation
- Highway or runway marking removal
3. Steel Plate Rust Removal and Roughening
In shipbuilding, bridge construction, and steel deck flooring, steel plates often require rust removal and roughening to improve anti-corrosion coating adhesion.
The floor shot blasting machine can achieve SA2.5 level cleanliness with consistent roughness, meeting most heavy anti-corrosion standards.
Typical applications include:
- Ship deck maintenance
- Bridge steel deck waterproof system preparation
- Steel plate flooring in industrial factories
4. Asphalt Road Surface Preparation
In municipal projects, shot blasting is used for asphalt surfaces to improve friction and skid resistance.
It can remove aging asphalt film and create micro-roughness, improving vehicle safety.
This application is commonly seen in:
- Airport runways
- Expressways
- Parking areas
- Tunnel entrances
5. Concrete Polishing and Leveling Assistance
Although shot blasting is not a polishing tool, it is often used before grinding.
It helps to open the pores of concrete and remove weak layers, which improves the efficiency and finish of later steps.
For flooring contractors, combining shot blasting + grinding becomes a standard construction process.
6. Surface Cleaning in Large Industrial Facilities
In heavy-duty industrial environments, floors are exposed to oils, chemicals, and dust.
Floor shot blasting can quickly restore the original surface condition and prepare for future maintenance.
Typical scenarios:
- Power plant floors
- Steel mill walkways
- Chemical plant processing areas
- Manufacturing workshop renovation
7. Anti-Skid Treatment for Public Spaces
Shot blasting is also used for creating anti-slip textures, especially in areas requiring safety enhancement:
- Pedestrian walkways
- Subway stations
- Ramps and slopes
- Wet-process factory floors
The roughened surface increases friction without damaging structural integrity.
Conclusion
From industrial construction to municipal engineering, the floor shot blasting machine plays an important role due to its high efficiency, dust-free operation, and excellent cleaning effect.
Whether for coating preparation, renovation, steel surface treatment, or asphalt roughening, the machine provides reliable and consistent performance.
