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%.
Anti-Leakage Spray Polyurea Sealing Coating: Comprehensive Guide
The demand for high-performance protective coatings in modern industries continues to grow. Anti-leakage spray polyurea sealing coating has emerged as one of the most reliable solutions for sealing, waterproofing, and protecting various structures. Known for its durability, flexibility, and rapid curing properties, polyurea technology ensures leak prevention even under extreme environmental and chemical exposure.
This article provides a detailed explanation of the structure, material composition, main functions, and maintenance strategies of anti-leakage spray polyurea coatings, making it a practical reference for industrial professionals, engineers, and procurement specialists.
The design of an anti-leakage spray polyurea coating system follows a layered and integrated structural approach to guarantee efficiency.
Base Layer (Substrate Preparation)
Concrete, metal, or composite surfaces are cleaned and primed.
Surface roughness ensures adhesion.
Primer Layer
Special primer applied to improve bonding.

Rapid curing (seconds to minutes, even at low temperatures).
High elongation (up to 600%) preventing cracks or failures.
Extreme chemical resistance against oils, acids, alkalis, and solvents.
Waterproof and vapor barrier properties.
Environmentally safe, as it contains no solvents or VOCs.
Forms a seamless and impermeable barrier.
Protects against water ingress, hydrostatic pressure, and capillary action.
Shields steel structures and pipelines from rust and chemical corrosion.
Extends the lifespan of industrial equipment and civil engineering assets.
High tensile and tear strength.

Suitable for tunnels, bridges, basements, dams, roofs, and industrial tanks.
Proper maintenance ensures the longevity of anti-leakage spray polyurea coatings. While polyurea is low-maintenance by design, scheduled inspections and preventive measures guarantee optimal performance.
| Inspection Frequency | Action |
|---|---|
| Quarterly | Visual inspection for cracks, peeling, or discoloration. |
| Annually | Detailed adhesion and thickness test. |
| Every 3–5 Years | Re-apply topcoat or local patch repairs if UV exposure is high. |
| As Needed | Spot repairs for mechanical damage caused by external impact or wear. |
Routine Cleaning: Use mild detergents and water spray.
Oil or Chemical Spills: Neutralize spills immediately with approved cleaning agents.
Dust and Debris: Remove using pressure washing or vacuuming.
Add UV-resistant topcoat for outdoor applications.
Reinforce with additional polyurea layers in high-wear zones.
Integrate monitoring sensors for smart maintenance in critical infrastructure.
