Hand brushed polyurea HBPUA types
1. Single-component hand-brushed polyurea "JCHBPUA-001", is a single-component polyurea waterproof material ready to use. Its purpose is mainly waterproof and expansion joint filling.
2. Two-component hand-brushed polyurea "JCHBPUA-002" is a two-component polyurea material. Its main purpose is waterproof and corrosion-resistant. It can be used on outdoor concrete or tile foundation floors. Its performance is second only to sprayed polyurea "JCSPUA-001", with 300% elongation, excellent weather resistance and waterproof performance.
3. Polyurea self-leveling "JCHBPUA-SL001" is a load-bearing polyurea floor material, suitable for indoor workshops and garage floors, or corrosive workshop floors. It has excellent physical and mechanical properties, the surface hardness can reach 7H, and it is waterproof and corrosion-resistant.
Application scenarios of hand-brushed polyurea HBPUA
Pools, outdoor concrete or tiled floors, reservoirs, workshops, terraces and other floors that require waterproofing.
How to use polyurea HBPUA by hand brushing
1. Base grinding, crack cutting treatment, and vacuum clean;
2. How to use the "JCEPDT-006" primer, apply the polyurea primer brush once, and there is whitening on the ground, and re-coat locally. "JCEPDT-006" is stirred evenly according to the label ratio, apply it evenly once with the medium-hair roller, and use it within 30 minutes.
3. How to use the sealing layer of the "JCEPZT-007" intermediate paint, and use a full batch of "JCEPZT-007" intermediate paint + quartz sand, stir evenly according to the label ratio, use a push knife to scrape it evenly, and use it within 30 minutes.
4. HBPUA is mixed evenly according to the label ratio and used within 20 minutes. The minimum unit consumption of all polyurea materials is 1.8 kg per square meter.
Precautions for hand-brushing polyurea HBPUA
1. The ground must be completely closed and no air holes are allowed.
2. Mix HBPUA evenly, control the discharge speed, ensure that the two components are discharged at the same time, and there is no deviation in the material.
3. The two-pass construction interval should not exceed 48 hours. After it exceeds, it must be polished.
4. The ground moisture content should not exceed 8%.

Proper storage ensures product performance and longevity:
Temperature: Store between 15–25°C in a dry, ventilated area.
Shelf Life: Typically 12 months in unopened containers.
Moisture Protection: Keep containers tightly sealed to prevent moisture contamination.
Avoid Direct Sunlight: UV exposure can degrade the resin components.
Handling: Use appropriate lifting equipment for heavy drums to avoid damage.
Remove dust, oil, grease, and loose debris.
Repair cracks, holes, and uneven areas to ensure uniform application.
Apply a primer for porous or oxidized surfaces to enhance adhesion.
Condition resin and curing agent to 20–25°C before mixing.
Mix thoroughly as per manufacturer instructions to achieve uniform consistency.
Apply evenly with brush, roller, or trowel.
Recommended thickness: 1.5–3 mm, depending on substrate type and chemical exposure.
Allow full curing for 24 hours before exposure to chemicals or mechanical stress.
Inspect for thin spots, bubbles, or voids.
Perform touch-ups to ensure continuous protective coverage.
| Problem | Cause | Solution |
|---|---|---|
| Poor Adhesion | Surface contamination or insufficient primer | Reclean surface, apply primer, recoat |
| Bubbles or Voids | Excess moisture or improper mixing | Ensure dry substrate, mix thoroughly |
| Cracking | Insufficient thickness or substrate movement | Apply thicker layer, allow full curing, avoid over-stretching |
| Chemical Damage | Exposure to unsupported chemicals | Ensure chemical compatibility, consider additional protective layers |
Routine Maintenance:
| Interval | Recommended Action |
|---|---|
| Weekly | Sweep or wipe with mild detergent; check for visible damage |
