Primer for Silicone Roof Coating System Offers Improved Adhesion, Blocks Asphalt Bleed-Through

Mule-Hide Products Co. Multibase SBMule-Hide Products Co. has expanded its Silicone Roof Coating System with Multibase SB, a new primer that delivers stronger adhesion and prevents asphalt bleed-through in non-ponding water conditions. Multibase SB is a one-part, 100 percent acrylic-based resin intended for use as a primer prior to the application of Mule-Hide 100% Silicone Roof Coating. It can be used on modified bitumen, asphaltic built-up roofing (BUR) and PVC roof surfaces.

According to the manufacturer, the primer contains minimal pigment and no mineral fillers, enhancing its adhesion to the roof surface. In addition, its relatively thin viscosity and low surface tension allows the primer to completely saturate the roof surface, further helping form a strong bond.

Multibase SB blocks asphalt bleed-through, helping ensure that white finish coats are clean and bright and deliver optimal reflectivity. The primer can be applied using airless spray equipment, a roller or a brush. Its light yellow color cures to a darker amber hue as the coating dries, providing visual confirmation that the coating has cured and the finish coating can be applied.

It is not intended for use on coal-tar-pitch roofs, on TPO membranes or in areas that experience ponding water. Multibase SB is available in 5-gallon pails and 55-gallon drums.

Silicone Sealant Repairs Roofs, Masonry and Sheet Metal

The 100 percent Silicone Sealant seals and repairs roofs, masonry, architectural sheet metal, and metal roof seams and fasteners.

The 100 percent Silicone Sealant seals and repairs roofs, masonry, architectural sheet metal, and metal roof seams and fasteners.

Mule-Hide Products Co. has added 100 percent Silicone Sealant choices to its Silicone Roof Coating System, expanding the color offering to include clear and the packaging options to include 10-ounce tubes.
 
100 percent Silicone Sealant is a mastic version of the Mule-Hide 100 percent Silicone Roof Coating. It is a 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 allows contractors to complete projects that would otherwise require color-matching. It is available packaged in tubes only.

In addition to clear, the tubes are available filled with white sealant. The plastic cartridges are an option for use in smaller applications or when precision is required. They also can be submerged under water to repair roof leaks, gutters and downspouts.
 
100 percent Silicone Sealant provides 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 building materials. When using 100 percent 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.
