Provides an excellent primerless adhesion to most common building materials, e.g. concrete, wood, masonry, different metals, glass, many plastics, etc. Permanently plastic. “Self-healing” behavior. Easy to use. Excellent UV- and weather resistance. Very low vapor and gas permeability. Non- corrosive to metals. Excellent adhesion to a wide range of porous and non-porous substrates. Overpaintable Practically odorless. Field of applications Butyl mastic can be used for sealing joints with low movements, where high weather resistance and permanently plastic behavior is expected. For example, metal roof sealing, sealing the lap joints between metal panels with the inclusion of fasteners, sealing window tins, repairing and renovation of roofs and gutters, sealing greenhouses. Can be used for airtight gluing and sealing of different membranes. Application conditions Application instructions The surfaces must be clean from dust, loose particles and oil.

This product requires skill and patience. The caulking dispenser was challenging. After applying it to the desired location, it threads after application.
