Minerallac 96062 FireStop Caulk 150+, 10.3 oz

Yes. The 96062 FireStop Caulk 150+ is intended as a general purpose fire rated sealant and smoke seal for construction joints, through-penetrations and blank openings on both vertical and horizontal surfaces, so wall penetrations and floor or ceiling deck assemblies are both in scope. The description names fire rated gypsum wallboard partitions, concrete block or concrete walls, and concrete or corrugated steel deck floor/ceiling assemblies.

Application temperature range is 40 to 120 degrees Fahrenheit. It is a water based sealant, so below 40 degrees you risk freezing and a failed cure. On a winter shell with no temporary heat, either heat the area or hold the firestopping until the building is tempered.

Yes. It is a caulking grade sealant described as easy to apply as well as retrofit, so you can gun it into an existing through-penetration around cable or conduit already in place rather than having to pull the run. Being non-sag, it stays put in an overhead or vertical opening.

It is a non-sag caulking grade sealant that can be used in areas with some movement, which is why it suits head-of-wall and construction joints rather than only rigid penetrations. For a penetration that stays static, the same product works fine, and because it is non-sag it holds position in overhead and vertical joints while it cures.

Functional cure is 3 to 4 weeks at 77 degrees Fahrenheit. It skins and holds much sooner than that, but if an inspector or a GC is signing off on a fully cured firestop joint, plan the schedule around that window. Cooler conditions will extend it.

It ships as a 10.3 oz cartridge in a tube, which runs in a standard full-size caulking gun. No bulk sausage pack or dispensing tool is needed.

No. The 96062 FireStop Caulk 150+ is specified for interior applications as a general purpose fire rated sealant and smoke seal. For an exterior penetration, use a sealant rated for exterior exposure instead.

Water based. That means uncured material cleans up with water off tools, hands, and adjacent finishes, and there is no solvent odor to manage in an occupied building. It also means the joint has to stay above 40 degrees Fahrenheit during application and early cure.

Red. The red color is what lets an inspector or a trade following behind you see at a glance that a penetration has been firestopped rather than filled with ordinary acrylic caulk. If the joint is in a finished, visible location, expect to cover or paint over it.

Yes, country of origin is the United States, which matters on Buy American or domestic-preference work in government, healthcare, and education projects.
