Product Overview
NRAC Non-Curing Waterproof Coating is a high-performance rubberized asphalt-based sealant designed for demanding waterproofing environments. Its non-curing formulation ensures permanent elasticity, allowing it to adapt to substrate movements, temperature fluctuations, and minor structural shifts--without cracking or peeling.
Engineered for large-scale waterproofing applications such as tunnels, bridges, rooftops, basements, and subways, this product delivers consistent sealing performance, even under extreme weather or heavy load.
Why Choose Non-Curing Technology?
Unlike conventional waterproof materials that harden over time, NRAC Non-Curing Coating remains flexible and viscous, allowing it to:
- Penetrate surface pores and cracks
- Self-heal minor damage and punctures
- Eliminate joint leakage due to rigid surface failure
- Deliver superior waterproofing over the long term

How to Use
Surface Preparation: Ensure substrate is clean, dry, and dust-free. Remove any oil, grease, or loose material.
Application Method: Brush, roller, or airless spray. Can also be used with fiberglass reinforcement layer.
Thickness: Recommended wet film thickness is 1.5-3mm. Apply in layers if needed.
Curing Time: Surface dry in 4-6 hours. Final setting in 24-48 hours (depends on environment).
Precautions:
- Do not apply in rain or below 5°C.
- Avoid contact with open flame or direct sunlight during storage.
- Do not ingest or allow contact with eyes.

Frequently Asked Questions (FAQ)
Q1: Is this product suitable for outdoor use in hot or freezing weather?
Yes. The coating is designed to perform in extreme temperatures from -25°C to +80°C and is UV-stable.
Q2: Can it be used in constantly wet environments like bathrooms or underground tanks?
Absolutely. Its non-curing nature ensures long-term waterproof performance even in submerged or high-humidity areas.
Q3: Is heating required before application?
No. This is a cold-applied material. No heating or melting is needed.
Q4: What makes it different from traditional asphalt or polyurethane coatings?
Unlike solidifying coatings, this product remains permanently flexible and does not crack or age easily, making it ideal for structures prone to movement or vibration.
