Metacaulk 150+, 5 gal Pail Firestop Sealant Metacaulk 150+ is a general purpose fire rated sealant designed for construction joints and through-penetrations. This water-based, elastomeric sealant prevents the spread of flames, smoke, hot gases, and water, making it suitable for use in firestop systems. It is ideal for interior applications on both vertical and horizontal surfaces, including gypsum walls, concrete floors, and wood floors, as well as around penetrations such as EMT, telephone, and power cables. Metacaulk 150+ supports dynamic movement and vibration, providing reliable fire, smoke, and acoustic sealing in building construction. It is a practical choice for electrical distributors and switchgear suppliers seeking effective firestop solutions.
