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%.
Handmade Polyurea Wear-Resistant and Weather-Resistant Coating: Complete Guide
Handmade polyurea wear-resistant and weather-resistant coating is a high-performance, hand-applied protective solution for industrial, commercial, and outdoor surfaces.

Ensure substrates are clean, dry, and free of grease, dust, or loose particles.
Repair large cracks, holes, or uneven surfaces to ensure uniform coating thickness.
For porous surfaces, apply a primer to enhance adhesion.
Store resin and curing agent at recommended temperature ranges.
Mix components according to manufacturer guidelines before application.
Hand-Applied Techniques:
Use brush, roller, or trowel to apply the coating evenly.
Maintain the recommended coating thickness: 1.5–3 mm for floors, 2–4 mm for outdoor structures.
Rapid Application Guide:
Prepare the substrate and ensure primer is applied if required.
Pour mixed polyurea onto the surface.
Spread evenly using a trowel or roller.
Smooth the surface for uniform coverage.
Allow 24 hours for full curing before heavy use or water exposure.
[Substrate] → [Primer Layer (if needed)] → [Hand-Applied Polyurea Coating] → [Optional Topcoat]
Daily Maintenance:
Sweep or rinse the surface to remove dust, debris, and spills.
Avoid dragging sharp or heavy objects across the surface.
Periodic Inspection:
Inspect for scratches, abrasions, or delamination.
Recoat any damaged areas to maintain full protection.
Maintenance Cycle:
| Interval | Task |
|---|---|
| Daily | Surface cleaning, debris removal |
| Monthly | Check for visible wear or micro-cracks |
| Quarterly | Minor touch-ups on damaged areas |
| Annually | Full inspection and recoating if needed |
Industrial Floors: Warehouses, factories, chemical plants.
Roofs and Terraces: Commercial buildings, outdoor structures.
Pipelines and Tanks: Concrete or steel structures for water, chemicals, and oil.
Bridges and Infrastructure: Concrete, steel, or composite surfaces exposed to weathering.
