Cromar Hydrosil Silicone Roof Coating – 18.9ltr Tin – Grey

Cromar Hydrosil is a professional grade, solvent-based, liquid-applied, single component, moisture‐cure premium silicone coating that has been specifically formulated to deliver direct‐bond adhesion as a restoration and maintenance coating over most common roof substrates and membranes.

Hydrosil forms a durable, vapor-permeable, watertight and weatherproof barrier that provides long-term resistance to degradation from natural weathering (including extreme temperatures, UV, rain and snow). The coating has excellent UV resistance and dries to a grey finish which keeps roof surfaces cooler preventing thermal shock and extending the life of the roof.

Independently tested and complies and/or exceeds all the requirements of ASTM D 6694 Standard Specification Liquid‐ Applied Silicone Coating used in Spray Polyurethane Foam Roofing Systems.

Hydrosil is approved for Class “A” Non‐Combustible credentials as tested under UL 790 Spread of Flame procedures over most common roofing substrates and membranes.

Application:

• Hydrosil may be sprayed, rolled or brush applied.
• Can be applied over surfaces that exhibit ponding water, however, it is advised that all roof systems be designed and built to ensure positive drainage.
• The coating must be evenly applied and pinhole-free.
• Hydrosil Coating should be applied at the recommended coverage of 1L/1.25sqm. Application rates must be checked periodically to ensure proper coating thickness. This may be done with a wet film gauge, or by checking coverage of a known quantity. The contractor should estimate coating requirements based on actual experience and needs to figure losses due to applicator experience, surface texture, wind, waste, and other factors increasing the estimated litres required.
