Extending roof longevity 

The primary goal of a roof coating is to enhance the durability of the roof. Diamond Roof Coat forms a seamless membrane that acts as a protective barrier against external factors. By reflecting ultra violet rays, protection from rain water, cracking, and physical damage, the roof coating shields the underlying roofing material, significantly extending its lifespan. Roofs are constantly exposed to weather conditions, which can accelerate the aging process and lead to costly repairs. With Diamond Roof Coat, building owners can rest assured that their roofs are protected and will require fewer repairs and replacements over time.

Energy efficiency is a significant concern for environmentally conscious individuals and businesses. Diamond Roof Coat plays a crucial role in reducing energy consumption within a building. By effectively decreasing roof surface temperatures, especially during hot summer months, the coating lessens heat transfer into the building’s interior. Choosing a suitable can contribute to both financial savings and environmental conservation.

Applications of Diamond Roof Coat

One of the key advantages of Diamond Roof Coat is its compatibility with various roofing materials, making it a versatile solution for different types of roofs. Its excellent adhesion over concrete and masonry surfaces allows it to be used as a Primer coat & top coat roofing system. Additionally, its elasticity makes it suitable for application on cementitious surfaces. Whether the roof is made of concrete, or cementitious surface. Diamond Roof Coat can provide a reliable protective layer, ensuring long-lasting performance and durability.

The versatility extends beyond roofing materials to encompass a wide range of surface types. Its excellent adhesion and waterproofing properties make it an ideal choice for flat and sloped roofs, concrete decks, parapet walls and flashings. Furthermore, its seamless nature allows for easy application without causing any disruptions or issues related to compatibility.

Surface preparation and application

Proper surface preparation is essential to ensure the optimal performance of any roof coat. Before applying the coating, all surfaces must be thoroughly cleaned and free from dust, oil, foreign particles and contaminants that may impair adhesion. The following surface preparation steps should be followed:

  • Wash the surface to remove contaminants.
  • Rinse thoroughly with water and allow it to dry.
  • Dull glossy areas by light sanding.
  • Remove sanding dust.
  • Remove loose paint.
  • Scrub heavy chalk areas with soap and water.
  • Eliminate mildew by washing with a solution of liquid household bleach and ammoniated liquid detergent in water.
  • Rinse surfaces clean with water and allow them to dry for 24 hours.

Diamond Roof Coat offers a simple application process, making it accessible to both do-it-yourself (DIY) enthusiasts and professional contractors. It can be applied using a roller, brush, or scraper. By adding fresh water to achieve a suitable consistency for smooth application and avoiding over-thinning, users can achieve the best results.

Smaller roofs in good condition are perfect for a DIY project, while larger roofs with complex issues such as leaks and ponding water are best coated by qualified professionals to ensure proper coverage and effectiveness. 

To achieve the perfect finish and ensure optimum protection, it is recommended to apply two to three coats. Each coat should be applied with a 4–6hr interval between them, allowing the previous coat to dry adequately. The drying time for touch dry and hard dry is approximately 2hr and 8hr, respectively, but may vary depending on temperature and humidity conditions.

Coverage and storage

Diamond Roof Coat boasts an impressive coverage rate of approximately 1.5Kg/m2, though this may vary depending on the nature of the surface, application technique and film thickness applied (recommended film thickness is 1mm for the required properties). Property owners can easily estimate the required amount of coating based on the total surface area of the roof and the recommended coverage rate.

Proper storage of Diamond Roof Coat is essential to maintain its quality and effectiveness. It is recommended to store the product away from direct sunlight and in a well-ventilated area, ensuring that the coating retains its properties until the time of application.
