A concrete shot blaster is a machine that cleans and roughens concrete surfaces. This floor shot blasting machine uses high-speed steel shots to remove laitance, old epoxy, paint, and surface contaminants. The impact opens the pores of the concrete and creates a rough, uniform profile. For epoxy floor installation, coating removal, and surface preparation, this concrete surface preparation equipment helps new coatings bond tightly and last longer.
YG Machinery offers floor shot blasters in YG-270, YG-550, and YG-850 models. Working widths range from 270mm to 850mm. Cleaning efficiency reaches up to 600m²/h on concrete surfaces.

Why Concrete Surfaces Need Shot Blasting?
Concrete floors often have problems that prevent coatings from sticking:
Laitance – A weak, powdery layer forms on fresh concrete surfaces. It must be removed before coating.
Old coatings – Existing epoxy, polyurethane, or paint layers need removal. New coatings will not stick to old coatings.
Surface contaminants – Oil, grease, and dirt block adhesion. They must be cleaned away.
Smooth surface – Coatings need a rough surface to grip. Smooth concrete does not provide enough mechanical bond.
Weak concrete – Surface concrete may be soft or deteriorating. It must be removed to reach solid material.
This concrete shot blaster solves all these problems:
This machine effectively removes laitance, weak concrete, and old coatings, while also cleaning away surface contaminants to create a rough, uniform profile.Coatings bond tightly to the prepared surface.
Applications of Floor Shot Blaster
This floor shot blaster is used in many surface preparation projects:
Removing concrete laitance – Removes the weak surface layer on fresh concrete. Prepares the floor for coatings.
Removing old coatings – Strips old epoxy, polyurethane, paint, and other coatings from concrete floors.
Epoxy floor preparation – Creates the ideal profile for epoxy floor coatings. Ensures strong adhesion.
Warehouse floor preparation – Prepares large warehouse floors for new coatings or overlays.
Bridge deck preparation – Removes old waterproofing and prepares bridge decks for new membranes.
Parking garage floors – Cleans and roughens parking garage floors for new coatings.
Airport runway friction restoration – Removes rubber buildup and restores friction on runways.
Steel surface cleaning – Removes rust and old coatings from steel bridge decks.
Road marking removal – Removes old road markings and lines from asphalt and concrete.
How to Choose the Right Floor Shot Blasting Machine?
Choosing the right floor shot blasting machine depends on your project size and space constraints.
| Your project type | Recommended model | Why |
| Small area, tight spaces, doorways | YG-270 | 270mm width, compact, fits through doors |
| Medium area, standard industrial floors | YG-550 | 550mm width, good balance of speed and maneuverability |
| Large area, open warehouses, big projects | YG-850 | 850mm width, highest efficiency, covers more area per pass |

Customer Case
A factory had a 2000m² old epoxy floor that was peeling and cracked. The owner needed to install new epoxy but the old coating would not stick. Grinding was too slow. They contacted YG Machinery.
A YG-550 floor shot blasting machine was brought to the site. The machine stripped the old epoxy in one pass. The surface was rough and uniform. New epoxy was applied the next day.
Results:
- Old epoxy removed in 2 days
- New epoxy applied without delay
- No dust in the work area
- The factory resumed production 3 days ahead of schedule
- The owner saved $5,000 compared to grinding
The site manager said: “The shot blaster removed the old epoxy quickly. The surface was perfect for new coating. The dust collector kept the work area clean.”

Factory-direct pricing saves customers 30-40% compared to comparable brands. Spare parts are shipped within 48 hours. Regular models ship within 7 days.
FAQ
Q: What is the difference between shot blasting and grinding?
A: Shot blasting uses high-speed steel shots to impact the surface. It creates a rough profile. Grinding uses abrasive discs to smooth the surface. Shot blasting is faster and creates better adhesion for coatings.
Q: How deep does the shot blaster remove concrete?
A: The concrete shot blaster removes 0.5-3mm of surface material, depending on walking speed and shot size. Deeper removal is possible with multiple passes.
Q: Can this floor shot blaster work indoors?
A: Yes. The integrated dust collector captures dust during operation. The work area stays clean and safe for indoor use.
Q: Does it damage the concrete underneath?
A: No. The machine removes only the surface layer. The machine leaves the sound concrete below undamaged.
Q: What surface profile does it create?
A: The profile depends on steel shot size and walking speed. It creates a rough, uniform surface ideal for epoxy and other coatings.
Q: How long does it take to clean a floor?
A: The YG-270 cleans 180m² per hour. The YG-850 cleans 600m² per hour. Time depends on the area and surface condition.
Q: Do I need to buy steel shots separately?
A: Steel shots are included with the machine. Replacement steel shots are available from YG Machinery.
Q: What is the warranty?
A: The main structure has a 24-month warranty. Motors and electrical components have a 12-month warranty. Wear parts like blasting blades are not covered.
Q: What is the price of a concrete shot blaster?
A: Price depends on the model and configuration. The YG-270 is the most affordable. The YG-850 costs more. Contact us for a quote based on your project size.
