This roof and gutter sealant is a butyl mastic formulated for sealing joints in gutters, roofs, flashing, and similar areas. The black 290ml cartridge is suitable for use with a standard applicator gun, making it straightforward to apply on-site.
It bonds securely to materials commonly found in roofing and gutter work, such as metal, plastic, and bituminous surfaces. The sealant is typically used to address repairs or provide a flexible seal around joints, including situations where exterior conditions are damp or exposed to weather.
