Metacaulk® 1000 is a one component, general purpose fire rated sealant and smoke seal for construction joints and through-penetrations. Metacaulk® 1000 is a water based, extremely intumescent, non-sag caulking grade sealant that is easy to apply as well as to retrofit. It cures to an elastomeric seal that is suitable where dynamic movement is expected. In the event of a fire, Metacaulk® 1000 will prevent the spread of flames, smoke, hot gases and water through joint openings and through penetrations. No dilution or mixing is required for use. No special skills are necessary for installation. Metacaulk® 1000 is applied with a conventional caulking gun, bulk loading gun or can be troweled from the pail. For large applications, it can be pumped directly from the pail. Metacaulk® 1000 systems are rated for 1, 2, 3 and 4 hours in accordance with the ASTM E814 (UL1479),UL 2079 and ULC-S115-95 test standards. Metacaulk® 1000 is protected in a wet stage as well as in a dry stage against mold growth with a combination of biocides.
