How to use SPUA "JCSPUA-001" in Jiancheng
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. How to use "JCSPUA-001" spray polyurea, use a professional high-pressure sprayer to perform spraying operations at a discharge speed of 1.1:1 to ensure that the discharge is consistent, the mixing is even, and the material cannot be deviated.
5. How to use "JCSPUM-001" polyurea topcoat, mix evenly according to the required ratio of the label, use an airless sprayer or a roller brush, apply evenly to ensure no bottom exposure phenomenon. Light colors can be constructed in two times, and the mixed materials must be used within 20 minutes.
Notes on using "JCSPUA"
1. The ground must be completely closed and no air holes are allowed.
2. Mix SPUA 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%.
High Elastic Spray polyurea waterproof coating
High elastic spray polyurea waterproof coating is a state-of-the-art protective coating designed to provide superior waterproofing, flexibility, and durability for a variety of applications. Its high elasticity enables excellent crack-bridging performance, while the spray-applied formulation ensures a seamless, continuous membrane that adheres strongly to substrates such as concrete, metal, and wood.
This coating is ideal for rooftops, basements, tunnels, water tanks, bridges, and industrial facilities, offering reliable protection against water ingress, UV exposure, and mechanical stress. Its fast-curing properties allow quick project completion, reducing downtime and labor costs.
This guide provides detailed information on testing standards, maintenance recommendations, installation guidelines, and real-world applications, optimized for Google SEO and professional audiences.

| Shore Hardness | ASTM D2240 / ISO 868 | 40–50 A |
| UV Resistance | ASTM G154 | No significant discoloration or cracking after 1000 h |
Tip: Always verify the coating batch with quality certificates before application.
Correct installation ensures long-term waterproof performance. Follow these steps:
Clean the substrate thoroughly, removing dust, oil, grease, or old coatings.
Repair cracks, holes, or uneven areas with compatible fillers.
Ensure the substrate is dry, structurally sound, and free of loose particles.
Prime the surface if required to enhance adhesion.
Use a high-pressure plural component spray machine designed for polyurea.
Adjust temperature and pressure according to manufacturer instructions.
Ensure hoses and spray guns are clean and functional.
Mix the two components (isocyanate and resin) via the spray system.
Apply a uniform coating layer, maintaining a consistent thickness (typically 1.5–2 mm per coat).
Allow the first layer to cure partially before applying additional coats, if required.
For vertical or overhead surfaces, apply in multiple passes to prevent sagging.
Polyurea cures rapidly (within 5–10 minutes at standard conditions).
Inspect for pinholes, thin areas, or uneven coverage.
Conduct adhesion tests after curing to ensure proper bonding.
| Step | Recommended Practice |
|---|---|
| Surface preparation | 2–4 hours depending on substrate condition |
| Equipment setup | 30–60 minutes |
| Spray application | Apply in uniform layers; maintain 1.5–2 mm thickness |
| Partial curing between coats | 5–10 minutes |
| Full curing | 24 hours before full water exposure |
