• Agricultural Buildings – Perfect for barns, sheds, silos, and other agricultural structures, offering superior protection against weathering, rust, and mold.
• New Metal Roof Installations – Apply during or shortly after installation for optimal long-term protection and energy efficiency.
• Roof Restoration – Use it to rejuvenate old or weathered metal roofs, sealing cracks, preventing further damage, and restoring their protective properties.
• Corrugated, Standing Seam, and Ribbed Metal Roofs – Suitable for all metal roof types, including galvanized steel, aluminum, and coated metals.
• Coastal and High-Humidity Areas – Perfect for roofs exposed to salty air or high moisture, offering increased corrosion resistance.
• Regions with Extreme Weather Conditions – Whether facing heavy rain, snow, intense sunlight, or freezing temperatures, it stands up to the toughest weather challenges.Product Features
• 100% Waterproof: Creates a seamless, durable barrier that prevents water infiltration, protecting your roof and interior spaces from costly water damage.
• UV Resistant: Protects against sun damage, preventing premature aging and fading, while maintaining the coating’s flexibility and strength under harsh UV exposure.
• Corrosion Protection: Shields your metal roof from rust, oxidation, and other forms of corrosion, extending its lifespan.
• Energy Efficient: Reflective properties help reduce heat absorption, keeping your building cooler and reducing energy costs, especially during the summer months.
• Easy Application: Can be applied with a brush, roller, or sprayer, making it perfect for both DIY projects and professional installations.
• Long-lasting Durability: The coating is highly resistant to cracking, peeling, and blistering, ensuring long-term protection.
• Environmentally Friendly: Low VOC content ensures the coating is safe for the environment and compliant with local air quality regulations.Storage and Transportation
1.Transport according to non-hazardous material requirements. During transport, avoid exposure to rain, direct sunlight, pressure, collision, or inversion. Ensure packaging remains intact, and maintain ambient temperature above 0°C. If the temperature falls below this, take necessary measures to maintain a constant temperature.
2.Store in a ventilated, dry place away from direct sunlight, with a storage temperature not lower than 5°C, and never below 0°C.
3.The product has a shelf life of 6 months under normal storage and transport conditions.Construction Requirements
1.The recommended temperature range for construction is between 5°C and 35°C, with a relative humidity below 85%. Avoid application during sandstorms or rainy weather.
2.After use, tightly seal the can to prevent contamination by dust and dirt.
3.This product should not be mixed with other brands of coatings. Wear protective equipment and a mask during application. If the coating gets into the eyes, rinse immediately with clean water. Clean tools with tap water after use.
4.After application, ensure the finished product is protected to prevent damage from subsequent construction activities.
5.Surface quality requirements: The color should be uniform without any defects such as visible pores, cracks, chalking, peeling, whitening, or other imperfections.Application Process
(1) Small Area Application:
In general, all horizontal and vertical connections on the roof must be handled with detail treatment. For expansion joints, ventilation openings, large pipelines, and other protruding structures, apply a "one and three coating" method with reinforced polyester fabric. After applying the base coating, press the fabric into the wet coating using a brush or roller, ensuring there are no air bubbles or wrinkles. Apply additional coating to ensure the fabric is fully saturated.
Specific treatment methods are as follows:
1.Roof Overlap Joints: Apply one coat of coating and lay a 15-20 cm wide polyester fabric over the joint. Saturate the fabric thoroughly with the coating to prevent bubbles or wrinkles.
2.Protruding Areas (e.g., Chimneys, Vents, Fans): Apply one coat of coating, then lay polyester fabric that matches the size and shape of the protruding area. Saturate the fabric with an additional coat of coating to prevent bubbles or wrinkles.
3.Fixed Components: Cut polyester fabric into appropriate square sizes and apply in the same way as for protruding areas.
4.Gutter Areas: For overlaps or downspouts, treat these areas with localized waterproofing using the same method as for protruding areas.
(2) Large Area Application:
The coating should be applied in two layers. After the first layer is applied and dried, apply the second layer. The time interval between coats is generally 12 hours, and should be extended in winter. The thickness of each coating layer should be about 0.5mm. Avoid applying the coating too thick in one layer. The application direction for each layer should be perpendicular to the previous one, ensuring even coverage without any missed spots.
