Hydrosil is a highly reflective Fluid Applied Professional Grade Silicone Coating System used to coat all existing roofing substrates.

System includes:

HYDROSIL PROFESSIONAL LIQUID SILICONE ROOF COATING is a professional grade 100% Silicone roof coating. This product is a high performance, solvent based, high solids, single component, moisture cure liquid applied silicone coating. HYDROSIL Professional liquid silicone is an elastomeric yet vapour permeable membrane exhibiting outstanding weathering and water resistance for application to most common roofing substrates.

HYDROSIL SEAM SEALER & DETAILER is a premium silicone multi-purpose mastic for detailing work & to cover all joints/seams prior to the application of Hydrosil (suitable for all roofing substrates). Upon cure, Seam Sealer & Detailer forms a durable, breathable and weatherproof barrier that is highly resistant to degradation from UV and natural weathering.

HYDROSIL HEAVY DUTY REINFORCEMENT ROLL is non-woven, spun bonded 100% polyester and used with HYDROSIL SEAM SEALER & DETAILER to reinforce seams, penetrations, joints or transitions that are subjected to high shear.

Cromar Hydrosil Reinforcement Roll is a heavy‐duty stitch bonded high performance fabric for use in cold applied restoration roofing and roof maintenance systems. It comes with lay lines for one- and two-ply roof systems. It is ideal as the reinforcing component in cold process roofing and repair with water‐based asphalt emulsion, acrylic coating, solvent type coatings, or mastics.

Tear strength, puncture resistance, and tensile strength combined with elongation Hydrosil Reinforcement Roll has been shown in tests with asphalt emulsion and cutbacks to be far superior to conventional roofing felts weighing five to seven times as much. Hydrosil Reinforcement Roll is a polyester that will readily conform to irregular surfaces and standing seam metal roof decks. It is also much easier to handle and apply properly than other soft polyester sheets.

Hydrosil Reinforcement Roll is designed specifically for use with the Hydrosil Silicone Roof Coating system.
