A pre-compressed, self-expanding, flexible, polyurethane joint sealant that is designed to seal against wind-driven rain, sound, draft and dirt. It is an exterior and interior seal impregnated with a flame-retardant, modified acrylic resin and treated with a pressure-sensitive adhesive on one side for easy installation. After positioning, the material self-expands to fill the void and create a permanently elastic, weathertight seal. It can be painted with any color of water-based, flexible paint. It is used as an exterior or interior joint sealant in applications above ground. It can be used as a primary or secondary seal in vertical applications.
Typical applications include expansion joints between tilt-up panels in commercial structures like office buildings, warehouses and distribution centers. Joints in pre-cast concrete, masonry, and brick facades used in the construction of hospitals, schools and government buildings. Interior or exterior face of window frames to seal from the wall opening to the head and rails. Can seal between metal flashings, from flashing to masonry, or fill exterior window flanges.
