※  Application

• Roofing Systems: Ideal for flat and sloped roofs, providing a reliable waterproof seal that extends the life of the roofing system.

• Basement and Foundation Waterproofing: Effectively prevents moisture penetration in below-ground applications, creating a dry and secure environment.

• Parking Lots and Paved Areas: Provides a durable waterproof layer, protecting surfaces from water damage and enhancing longevity.

※  Material Features

• Exceptional Waterproofing: Creates a robust, waterproof barrier that effectively prevents moisture infiltration, protecting structures from water damage.

• Non-Curing Technology: Remains flexible and pliable after application, allowing it to accommodate movement in the substrate without cracking or losing adhesion.

• Easy Application: Designed for simple application using brushes, rollers, or spray equipment, making it user-friendly for both professionals and DIY enthusiasts.

• Durability: Resistant to UV rays, extreme temperatures, and harsh weather conditions, ensuring long-lasting performance and protection.

• Versatile Use: Suitable for a wide range of applications, including roofs, foundations, basements, and below-grade waterproofing.

※ Usage Instructions:

1. Surface Preparation: Ensure surfaces are clean, dry, and free from debris. Remove any existing coatings or contaminants that may affect adhesion.

2. Mixing: If required, stir the coating thoroughly to achieve a uniform consistency before application.

3. Application: Apply the coating evenly using a brush, roller, or spray equipment, ensuring full coverage on the surface. Aim for a minimum thickness of 1-2 mm.

4. Curing Time: Allow the coating to dry naturally. Full performance is typically achieved within 24-48 hours, depending on environmental conditions.

※ Construction Requirments

1. Surface Preparation:
Proper surface preparation is critical to ensure effective adhesion and long-lasting performance of NRAC Non-Curing Rubber Bitumen Waterproofing Coating. The steps are as follows:

• Cleaning: The substrate must be free of dust, oil, grease, dirt, and loose particles. Pressure washing or scrubbing with appropriate detergents is recommended.

• Drying: Ensure that the surface is dry and smooth, as moisture can affect adhesion.

• Priming: On porous or rough surfaces like concrete, use a primer to enhance adhesion and prevent excessive absorption of the coating.

2. Environmental Conditions:
The surrounding environment plays a crucial role in the performance and durability of the waterproofing coating:

• Temperature Range: Apply the coating in temperatures ranging from 5°C to 35°C. Avoid application in freezing conditions or during heavy rainfall, as this can interfere with the curing process.

• Humidity: Moderate humidity levels (30%-70%) are ideal. Excessively high humidity may prolong the drying time, while low humidity may accelerate drying, affecting workability.

3. Application Method:
To achieve the desired waterproofing effect, follow the steps below:

• Mixing: Thoroughly stir the coating before use to ensure a uniform consistency. Mechanical stirring is preferred for larger volumes.

• Application Tool: The coating can be applied using a trowel, brush, roller, or spray equipment, depending on the surface area and project scale.

• Layer Thickness: Apply the coating in layers, ensuring that each coat is approximately 1-3 mm thick. For best results, apply 2-3 layers, allowing time for each layer to set before applying the next.

• Joint Treatment: Pay special attention to joints, corners, and edges, where water tends to accumulate. These areas may require additional material to create a thicker, reinforced layer.

4. Drying and Curing Time:
While the NRAC Non-Curing Rubber Bitumen Waterproofing Coating remains non-curing, giving it the flexibility to move with the substrate, allowing some time between layers is important:

• Tack-Free Time: The coating will be tack-free within 4-6 hours under normal environmental conditions.

• Traffic-Ready: Light foot traffic is possible after 24-48 hours, depending on the ambient temperature and humidity levels.

• Full Performance: Although the coating remains pliable, optimal waterproofing performance is achieved after 48 hours.

5. Safety Measures:
Ensure safe working conditions during the application process:

• Personal Protective Equipment (PPE): Use gloves, goggles, and masks to protect against chemical exposure.

• Ventilation: For enclosed areas, ensure proper ventilation to prevent the buildup of fumes from solvents present in the coating.

• Storage: Store the product in a cool, dry place, away from direct sunlight and open flames. Properly seal the container after each use.

6. Maintenance and Reapplication:
NRAC Non-Curing Rubber Bitumen Waterproofing Coating provides long-lasting protection but regular inspections are necessary to maintain its effectiveness:

• Regular Inspection: Periodically inspect the waterproofed areas for signs of damage or wear, especially in high-traffic zones.

• Repair: If cracks or damage appear, simply apply additional coating in the affected areas, ensuring proper surface preparation beforehand.

• Reapplication: Reapply the coating every 5-10 years, depending on exposure to harsh environmental conditions, to maintain optimal waterproofing.

※ Storage and Transportation

Store in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the container is tightly sealed when not in use to maintain product integrity.

※ Safety Precautions

Always wear appropriate personal protective equipment (PPE), including gloves, goggles, and masks, during application. Ensure adequate ventilation in enclosed spaces to avoid inhaling fumes.
