Description
Mastic sealant tape
Black Butyl Tape for Concrete Pipes and Manholes
Manhole sealant is an all weather butyl rubber sealant for concrete joints. Butyl sealants are far superior to mastic made from oil or asphalt because they are rubber based.a preformed butyl joint sealant that is supplied in rope form. It is carefully blended from uncured butyl rubber and other solids and will not shrink, crack, or dry out.
Although clean to handle, it provides excellent adhesion and cohesion to a wide variety of surfaces - concrete, metal, most concrete coatings, glass, wood, and painted surfaces.
