Engineered for Indian climatic challenges, Sikalastic-520 Cool Coat Fibers IN delivers a high Solar Reflectance Index (SRI 112) that minimizes surface temperature and heat ingress, helping to keep interiors cooler and reduce energy consumption for air conditioning. The flexible membrane allows for crack-bridging up to 3.2 mm, offers superb adhesion to a wide range of substrates—including concrete, brick, tiles, asbestos and metal decks—and resists permanent UV exposure, weathering, chloride ingress, mould, and fungus. Its low VOC formula is environmentally sound and user-friendly, offering a smooth finish that improves both thermal efficiency and waterproof reliability.

Application Methodology

  • Step 1: Clean and prepare the substrate. Ensure it is dry, sound, and free from contaminants, with moisture < 6%.

  • Step 2: Prime surface with Sikalastic-10 Primer W (0.2–0.3 kg/m²/coat) for optimal adhesion.

  • Step 3: Mix Sikalastic-520 Cool Coat Fibers IN gently prior to application to ensure uniformity.

  • Step 4: Apply the base coat by brush or roller (0.75 kg/m² per coat for roofs).

  • Step 5: For high movement cracks or demanding areas, reinforce with Sika Fabric-50 between coats as specified.

  • Step 6: Allow 6–8 hours curing between coats, then apply the second/top coat (0.75 kg/m² per coat).

  • Step 7: For enhanced cleanability or dirt resistance, a thin clear coat of Sikalastic-10 Primer W can be added.

  • Ready for light traffic in approximately 24 hours; avoid water ponding for at least 7 days.
