Application of spray-coated polyurea (SPUA)
Sprayed polyurea is an excellent high-end waterproof and anticorrosion coating. Its excellent density and weather resistance are suitable for extremely harsh outdoor environments, and are resistant to high and low temperatures, and the elongation rate of break can reach more than 400%. It can be used in all areas where waterproofing is needed, such as outdoor swimming pools, roof tiles waterproofing, reservoir waterproofing, storage tank waterproofing, anti-corrosion, pipe corrosion protection and other fields.
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%.

Daily Maintenance:
Sweep or rinse surfaces to remove dust, debris, and chemical residues.
Clean minor spills immediately using mild detergents.
Weekly Inspection:
Check for scratches, punctures, or signs of wear, especially in high-traffic areas.
Inspect edges and joints for adhesion integrity.
Monthly / Quarterly Maintenance:
Conduct a visual inspection for UV or chemical degradation.
Verify coating thickness with ultrasonic gauges if necessary.
Annual Maintenance:
Perform a detailed inspection for cracks, pinholes, or corrosion underneath the coating.
Touch up or recoat areas showing wear to maintain full protection.
| Problem | Possible Cause | Solution |
|---|---|---|
| Peeling or poor adhesion | Contaminated surface or improper primer | Clean substrate and reapply primer |
