A hand-applied concrete floor protection system for prepared industrial floors, workshops, corridors, equipment rooms and semi-exposed floor areas. It helps build a sealed, leveled and wear-resistant floor coating structure for projects exposed to abrasion, foot or light vehicle traffic, water contact, occasional chemical splash and outdoor weathering.
Concrete primer + two quartz-sand hand-applied polyurea build layers + exposed wear-resistant polyaspartic topcoat
Concrete pore sealing and adhesion support for prepared floor substrates
Coarse-sand scrape layer for fine defect filling and initial build thickness
Fine-sand build layer for added thickness, surface uniformity and sanding-ready preparation
Exposed polyaspartic floor finish for wear, weather and surface protection
The system separates concrete pore sealing, quartz-sand build thickness and exposed surface protection, helping reduce substrate-related defects, surface wear and long-term floor maintenance risks.
BW8009 seals prepared concrete, reduces uneven absorption and supports adhesion before the hand-applied build layers are applied. It helps create a more stable bonding base for porous, dusty or mineral concrete floor substrates after proper surface preparation.
BW6-9527 blended with coarse quartz sand forms the first scrape-applied build layer. It helps fill small pores, shallow defects, rough texture and local uneven areas, creating a more continuous base before additional build thickness is applied.
The second BW6-9527 quartz-sand build layer adds thickness and creates a sanding-ready surface before the exposed topcoat. After curing and sanding, it helps improve surface uniformity, reduce local irregularities and support a smoother topcoat finish.
BW0-8027 forms the exposed wear-resistant and weather-resistant floor topcoat. It helps improve abrasion resistance, surface durability, color stability and maintainability under foot traffic, light vehicle traffic, water contact, occasional chemical splash and outdoor exposure.
The system is built through concrete floor preparation, BW8009 primer application, two BW6-9527 quartz-sand scrape layers, sanding after the second build layer and BW0-8027 exposed topcoat application.
Prepare a solid, clean, dry and stable concrete floor before coating work begins. Remove loose concrete, laitance, dust, oil, standing water, weak surface layers and contamination, then review floor strength, moisture, flatness, defect depth and repair scope before primer application.
Apply BW8009 as the concrete primer to seal capillary pores, reduce absorption differences and support adhesion before the hand-applied build layers. Primer coverage, recoat timing and substrate condition should be controlled so the following BW6-9527 layers are applied over a stable prepared surface.
Apply BW6-9527 blended with coarse quartz sand as the first scrape-applied build layer. This layer helps fill fine surface defects, pores and shallow uneven areas while starting the main hand-applied build structure for the floor system.
Apply the second BW6-9527 layer with fine quartz sand for additional thickness and surface uniformity. After curing, sanding or grinding should be used to improve flatness, remove surface irregularities and prepare a suitable base for BW0-8027 topcoat application.
Apply BW0-8027 as the exposed floor topcoat after the quartz-sand build layers are cured, sanded and cleaned. This layer provides the final wear-resistant, weather-resistant and maintainable floor surface.

The above values are selected from the current product-detail Product Information, Physical Properties and Chemical Resistance tables. Final film thickness and suitability should be confirmed according to substrate condition, service exposure, detail design, project specification and the latest approved technical data sheet.
Before handover, key inspection should focus on concrete floor readiness, BW8009 primer continuity, BW6-9527 quartz-sand build stability, sanding uniformity and BW0-8027 exposed topcoat condition.
Confirm the concrete floor condition before primer application.
Review both scrape-applied BW6-9527 quartz-sand build layers before topcoat application.
Check the exposed BW0-8027 floor finish before service.
Use these checks to judge whether the BW8009 + BW6-9527 + BW0-8027 system is suitable before final specification.
For prepared concrete floors in workshops, corridors, equipment rooms and similar areas where abrasion, cleaning, foot traffic or light vehicle traffic need surface protection. Review industrial floors before confirming suitability.
For concrete floors with pores, dusting, rough texture or uneven absorption where primer sealing and quartz-sand build layers can improve the coating foundation.
For floor areas with fine cracks, small voids, local defects, low spots or uneven surface profile where scrape-applied build layers and sanding can improve continuity before topcoat application. Review leveling before confirming suitability.
For semi-exposed floors or outdoor floor areas where water contact, weather exposure, UV exposure, occasional chemical splash and topcoat aging need to be reviewed before specification.
Do not finalize material consumption from floor area alone. Confirm concrete condition, surface strength, moisture, roughness, defect depth, required build thickness, sanding requirement, traffic load, chemical splash exposure, outdoor weather exposure, topcoat color and inspection standard before ordering.
