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%.

Q1: Can polyurea membranes be applied on wet surfaces?
A1: Certain formulations allow application on slightly damp surfaces, but optimal adhesion requires a dry substrate.
Q2: How thick should the coating be for long-term protection?
A2: A typical layer ranges from 1.5 mm to 3 mm, depending on exposure conditions and substrate type.
Q3: How long does it take to fully cure?
A3: Touch-dry in seconds, but full mechanical properties develop within 24 hours at room temperature.
Q4: Is spray polyurea environmentally safe?
A4: Yes, most modern formulations are solvent-free, low-VOC, and meet international environmental standards.
Q5: Can it withstand UV exposure?
A5: Yes, high-quality membranes are UV-resistant and maintain performance under prolonged sunlight.
Ensuring proper application and long-term durability requires adherence to strict inspection standards:
Thickness Measurement: Verify uniform thickness using ultrasonic gauges.
Adhesion Test: Conduct pull-off tests according to ASTM D4541.
Curing Verification: Check hardness and flexibility after 24 hours.
Visual Inspection: Ensure continuous, defect-free coverage with no pinholes or voids.
Waterproof Testing: Conduct ponding or hydrostatic pressure tests to confirm impermeability.
Routine maintenance prolongs the lifespan of spray polyurea membranes:
Sweep or rinse surfaces to remove dust and debris.
Immediately clean chemical spills using mild detergent solutions.
Check for scratches, punctures, or wear in high-traffic areas.
Assess adhesion and elasticity, particularly on horizontal surfaces.
Perform detailed inspection for UV degradation, chemical exposure, or mechanical damage.
Recoat or touch up damaged areas to maintain full waterproof and anti-corrosion performance.
