100% Silicone Sealant is a thicker, mastic version of the Mule-Hide 100% Silicone Roof Coating. It is a high-solids, solvent-free, non-shrinking, moisture-cure silicone sealant designed for use in sealing and repairing roofs, masonry, architectural sheet metal, and metal roof seams and fasteners.
The addition of Clear sealant makes it easy for contractors to complete projects that would otherwise require meticulous, time-consuming color-matching. It is available packaged in tubes only.
In addition to Clear, the tubes are available filled with White sealant. The durable, weather-resistant plastic cartridges are a convenient option for use in smaller applications or when extra precision is required. They also can be submerged under water to repair roof leaks, gutters and downspouts.
100% Silicone Sealant provides excellent adhesion to concrete, masonry, polyurethane foam, EPDM membranes, TPO membranes, aged PVC membranes, aged acrylic coatings, granular cap sheets, wood, metals, Kynar finishes and most other common building materials. When using 100% Silicone Sealant with a TPO roof membrane, Mule-Hide Si TPO Primer must be applied first.
The sealant has minimal odor, making it contractor- and building-occupant-friendly. Its volatile organic compound (VOC) content of less than 10 grams per liter makes it acceptable for use in areas with VOC restrictions. It does not corrode metals.
