150+
General Purpose Firestop Sealant
Description
Metacaulk 150+ is a one component, general purpose fire rated sealant, acoustic
sealant and smoke seal for construction joints and through-penetrations. Metacaulk
150+ is a water based, non-sag caulking grade sealant that is easy to apply as well
as retrofit. It cures to an elastomeric seal that is suitable where dynamic movement
is expected. In the event of a fire, Metacaulk 150+ 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 150+ 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 150+ systems are rated for up to 4 hours in accordance with ASTM
E814 (UL 1479) and ASTM E1966 (UL 2079) test standards. Metacaulk 150+ is protected
in a wet stage as well as in a dry stage against mold growth with a combination of
biocides.
