South African roofs face strong sunlight, high temperatures, heavy rain, and changing weather conditions. Over time, these conditions can lead to cracking, aging, and water leakage.
High-solids silicone roof coating forms a seamless, flexible waterproof layer that helps protect commercial roofs from UV exposure while accommodating the normal movement of roofing materials. For contractors, distributors, and project buyers looking for a practical roof waterproofing solution, it is a reliable choice.
Why Contractors Choose Silicone Waterproof Roof Coating
Roofing conditions vary across South Africa. Coastal areas of Durban experience high humidity and heavy rainfall, while the Northern Cape is exposed to strong UV radiation. Commercial flat roofs in Gauteng may also experience occasional ponding water. Over time, these conditions can cause traditional roof coatings to crack, peel, or lose waterproofing performance.
Tengyu TW320 Silicone Waterproof Coating is designed for roofs exposed to strong sunlight, rain, humidity, and changing weather conditions. The flexible waterproof coating adapts to normal roof movement and resists UV and weather exposure.
As a single-component, ready-to-use coating, TW320 can be applied with a brush or roller and is suitable for commercial roofing applications.
Silicone Waterproof Coating: Applications, Methods and Conditions
Tengyu TW320 Silicone Waterproof Coating is mainly applied by brush or roller, depending on the roof area and project requirements. Brush application is more suitable for edges, corners, details, and smaller areas, while rollers are more convenient for larger roof surfaces. Spray application is possible with suitable professional equipment, but it is not the usual application method.
TW320 can be used for flat roofs, metal roofs, concrete roofs, and roof refurbishment projects, where additional waterproofing and weather protection are required.
Before application, make sure the substrate is clean and dry, and free from dust, oil, loose coatings, and other contaminants. For the recommended coverage rate and drying time, refer to the latest TW320 technical data sheet.
Check the weather before application and avoid rain during curing. Avoid application during rain or when rain is expected before the coating has fully dried. On roofs exposed to strong sunlight and high temperatures, applying during cooler hours can make the coating easier to handle and help achieve a more even finish.
30 Years of Protection With UV Reflection for Commercial Roofs
Tengyu TW320 silicone waterproof roof coating has an effective service life of up to 30 years, reducing the need for frequent roof maintenance and replacement. For commercial buildings, this can help reduce long-term maintenance requirements.
South African roofs are exposed to strong sunlight for much of the year. TW320 can reflect UV radiation and solar energy, helping reduce heat buildup on the roof surface. For commercial buildings, this provides an additional thermal benefit alongside waterproofing protection.
