Durajoint Construction Sealant Adhesive - 10.1 oz
Durajoint Construction Sealant Adhesive is a one-component, moisture-curing, low-modulus hybrid sealant built for demanding jobsite conditions. Ideal for expansion joints, flashing transitions, concrete repairs, and containment structures, it forms a durable, flexible bond that withstands movement, vibration, and extreme temperatures. This advanced polymer formula adheres strongly to concrete, masonry, metal, wood, flexible plastics, and rubberized asphalt flashing—even on damp or slightly oily surfaces. It’s also compatible with SBS-modified membranes, making it a smart choice for flashing and building envelope transitions. Durajoint performs in harsh environments with exposure to UV, moisture, and hydrocarbons, making it well-suited for both new construction and critical repairs. It cures in a wide temperature range (-40°F to 140°F), is paintable in 2 hours, and contains no solvents or harmful VOCs, making it safe for use indoors or in confined areas.
