• Prior to coating ensure all surfaces are clean, dry and free of dust, dirt, grease, wax and any other incompatible substances.
• Cover all flashing details, joints & seams using the Hydrosil® Seam Sealer & Detailer, ensuring it is thoroughly cured before applying Hydrosil® Silicone Roof Coating.

• Do not thin product with solvent or other solutions.
• Product may separate during shipping and storage, though it may still look mixed. Mix well before using.
• When product is in 18.9 L drums, use a 7.62 cm (3”) minimum diameter-mixing blade. Hand mixing with a suitable mixing blade is acceptable. DO NOT OVER-MIX.
• Containers are packaged with a layer of dry nitrogen, to keep latent moisture from prematurely starting the curing process.
• Once opened, the product has a pot life of 2-6 hours, depending on relative humidity conditions.

• Hydrosil® may be sprayed, rolled or brush applied.
• Coating must be evenly applied and pinhole free.
• Hydrosil® Coating should be applied at the recommended coverage of 1 L/1.25 m².
• Application rates must be checked periodically to assure proper coating thickness. This may be done with a wet film gauge, or by checking coverage of a known quantity.
• After the Hydrosil® Seam Sealer & Detailer has thoroughly cured, pour base coat onto roof in a narrow pass for approximately 6 meters and spread with the squeegee or 45 cm applicator brush at an application rate designed to achieve the recommended coverage of 1 L/1.25 m².
• Immediately back-roll the area evenly with an 23-45 cm roller, perpendicular to the squeegee pattern. Care should be taken to back-roll immediately before coating begins to dry.
• The Hydrosil® Silicone Roof Coating shall completely cover all expansion joint covers, parapets and flashings applied at an application rate designed to achieve the recommended coverage of 1 L/1.25 m².
