Project Background
The customer is a Turkish company specializing in industrial flooring, logistics warehouse, and parking lot floor works. This project covers an existing concrete warehouse floor, and the construction target is substrate preparation before epoxy floor coating.
The original concrete surface had laitance, dust, a small amount of curing agent residue, and partial old coatings. If these weak surface layers are not fully removed, epoxy primer cannot penetrate well, coating adhesion will drop, and peeling or delamination may easily occur later under frequent forklift traffic and heavy loads.
Shot blasting uses high-speed steel grit impact on the concrete surface to remove laitance and contaminants and creates an even rough micro-texture, improving primer penetration and coating adhesion.
Customer Requirements & Site Conditions
The customer wanted to purchase an efficient concrete floor shot blasting machine capable of fast large-area treatment, consistent roughness, and indoor low-dust construction.
Construction area: around 12,000 m² indoor concrete floor
Substrate condition: concrete laitance, dust, light oil stains, and residual old coatings
Treatment target: clean, dry, and rough concrete surface that meets epoxy primer requirements
Construction environment: indoor warehouse with strict dust control rules
Power supply: 400 V / 50 Hz industrial power
Schedule requirement: finish floor preparation before the epoxy coating team arrives
The site floor was relatively flat and dry with no standing water, satisfying basic shot blasting conditions: floor unevenness less than 10 mm, slope below 25°, and relative humidity no higher than 95% during shot blasting.
Solution & Model Selection
Based on the floor area, site photos, and construction schedule provided by the customer, YG recommended and confirmed the YG-850 double-blast wheel concrete floor shot blasting machine.
This model delivers an 800 mm cleaning width and concrete cleaning efficiency above 600 m²/h, ideal for warehouse main aisles, workshops, and wide-open floors. Twin 15 kW shot blast motors deliver stronger and stable blasting power. Paired with 1.5–1.8 mm steel grit, it produces the proper surface roughness for epoxy bonding.
Compared with YG-270 or YG-550/600, YG-850 features a wider single-pass coverage, fewer back-and-forth runs, and higher productivity for large jobs. For this 12,000 m² warehouse floor, the customer prioritized overall lead time and output, so YG-850 was the better floor shot blaster for sale option.
On-site Performance & Benefits
After delivery, the customer ran test blasting on corners and test zones. After confirming grit size, travel speed, and blasting quality, large-area work started. The YG-850 concrete floor bead blaster removed laitance and old coating residues while forming a uniform rough profile. The 8-core automatic back-blow dust collector reclaimed steel grit and captured dust at the same time. The treated floor was ready directly for epoxy primer application.
Key outcomes on site:
Average working efficiency of roughly 600–650 m²/h in open zones
Wider cleaning width than 550/600 mm models, significantly fewer repeated passes
Greatly shortened total construction time for the 12,000 m² floor
Consistent surface roughness for good epoxy primer penetration and bonding
Dust collection system effectively suppressed dust to meet indoor environmental standards
Steel grit circulated and recycled inside the machine to cut consumable costs
Laitance and loose material fully removed, creating a stable base for epoxy flooring
Shot blasting completes cleaning, old coating removal, and surface texturing in one step, generating a rough profile that helps coatings bond firmly. It is an efficient pretreatment method for large concrete floors.
Complete model range: 270 mm, 550/600 mm, and 800 mm working widths for different project sizes
High efficiency: concrete cleaning efficiency reaches over 180, 400 and 600 m²/h respectively
Dust control & eco-friendly: matched automatic back-blow dust collector, suitable for indoor and dust-sensitive sites
Reusable steel grit: internal separation and recovery reduce grit consumption
Wide application: concrete floors, bridge deck waterproof texturing, airport runways, steel rust removal, road marking removal, old coating stripping, etc.
Clear service life for wear parts: impeller and control cage last around 20,000 m²; top and side liners around 50,000 m²
For this Turkish customer, the YG-850 matched all project needs in construction speed, working width, dust control, and local power compatibility, making it the final pick.
Operation & Daily Maintenance Tips
Check the floor before work; remove standing water, oil, loose debris, and large contaminants.
Make sure the concrete surface is dry, and humidity meets shot blasting requirements.
YG-850 is recommended to use 1.5–1.8 mm steel grit. Adjust travel speed according to target roughness.
Keep steady travel speed. Overlap adjacent blasting strips properly to avoid missed areas or uneven texture.
Inspect the dust collector, filter cartridges, and airflow condition before starting each shift.
Empty the dust bin regularly and check for blockages in the grit recovery system.
Clean the machine after work and check wear on the blast wheel, control cage, and liners.
Store steel grit in dry containers to prevent caking from moisture.
Replace worn control cages and blast wheels in time; normal service life is about 20,000 m².
Do not operate in rain or snow. Avoid working on wet pools or heavily uneven concrete floors.
FAQs about Concrete Floor Shot Blasting Machine
Q: Can steel grit be reused? How often should I top it up?
Yes. The machine separates grit from dust via its recovery system for recycling. Normal grit consumption is around 10 g/m². Add or replace grit regularly based on recovery volume, blasting results, and grit breakage.
Q: How to pick the right model?
YG-270 for small areas, aisles and corner work; YG-550/600 for medium and large floors such as warehouses and factories; YG-850 for high-efficiency large-scale projects.
Q: What surface profile can shot blasting achieve?
By adjusting grit size, blast volume, and travel speed, you can get concrete roughness suitable for epoxy, polyurethane, and mortar overlays. Most coating systems require a CSP 3–5 surface profile.
Q: Does the floor have to be dry?
Yes. Concrete must be dry and free of standing water before blasting. A dry substrate is especially critical for adhesion when applying resin flooring systems later.
Q: Will a bead blaster for concrete floors damage the concrete surface?
Proper operation will not harm sound concrete substrate. Shot blasting removes only surface laitance, contaminants, and weak layers to create a controlled rough texture. Over-texturing may happen if you use oversized grit, move too slowly, or blast the same spot repeatedly. Always run a test blast first to set parameters.
