What is Polyurea? An ultra-durable and fast-curing waterproofing and coating technology.
Polyurea is a two-component, fast-curing coating and waterproofing system distinguished by its high elasticity, abrasion resistance, and water impermeability. Applied by spraying using reactive spray technology, polyurea provides superior performance in a wide range of applications, from industrial floors to roofs and terraces, water tanks to bridges.
Where is polyurea used?
Polyurea systems are preferred for both waterproofing and surface protection in the following areas:
- Waterproofing for terraces, balconies and roofs.
- Parking and industrial floor coverings
- Water storage facilities, drinking water tanks, and pools.
- Bridge, viaduct and infrastructure surfaces
- Tunnel interior linings
- Insulated sandwich panel and container surfaces
- For impact and chemical protection on concrete, metal, and wood surfaces.
Key Characteristics of Polyurea Systems
- Two-Component Reactive System: Polyol and isocyanate components are mixed using high-pressure spray equipment, resulting in surface curing within seconds.
- Ultra-Fast Curing: Adheres to the surface in 2–10 seconds, ready for traffic within minutes. Large areas can be covered in a short time.
- High Elasticity and Fracture Bridging: Adapts to structural movements thanks to its elasticity of up to 400%.
- Seamless, Joint-Free Surface: Because it is applied using the spray method, it forms a completely monolithic, watertight, and continuous layer.
- Chemical and Mechanical Resistance: It has high resistance to many chemical substances such as acids, bases, salt water, and fuels.
What are the types of polyurea?
1. Pure Polyurea:
This type offers the fastest curing and highest physical strength. It is suitable for demanding industrial and infrastructure applications.
2. Hybrid Polyurea (Polyurea Hybrid)
• Contains polyurethane additive. More economical and more flexible to apply. • Commonly used in areas such as terraces, parking lots, and warehouses.
3. Flame Retardant Polyurea:
Used in areas with high fire risk.
Can achieve B1-B2 fire classes with special formulations.
Advantages of Polyurea Coating
✔ Dries in Seconds: Saves labor and eliminates waiting time.
✔ Seamless and Leakproof: There is no risk of water leakage, joint defects, or welding errors.
✔ Superior Protection Against Abrasion and Impact: Forklifts, vehicle traffic, impacts, and chemicals leave no marks on the polyurea surface.
✔ High Adhesion Strength: Adheres perfectly to many surfaces such as concrete, metal, wood, and PVC with a primer.
✔ UV and Temperature Resistance: UV resistance can be increased with special formulations. Maintains its performance over a wide temperature range.
Frequently Asked Questions (FAQ)
Does polyurea application require special equipment?
Yes. The application requires high-pressure, temperature-controlled polyurea spray machines and a specialized team.
Is polyurea UV resistant?
Standard polyurea has limited resistance to UV light. However, this resistance can be increased with formulations containing UV stabilizers.
How long will it take to be available?
The surface dries within minutes. Traffic can usually resume within 30–60 minutes.
Can it be applied directly to concrete?
The surface must be primed and be clean, dry, and sound. Special polyurea primers are used to increase adhesion.
