RectorSeal Metacaulk MC150 Fire Caulk

Fire rated sealant that goes on smooth and settles into a solid, flexible seal.

A water based smoke seal that handles the awkward spots without making a mess.

Product Overview:

When you are sealing joints and through penetrations, you want the job to stay neat and hold up. This fire caulk gives you that. RectorSeal Metacaulk MC150 is a one component, water based sealant that applies cleanly, then cures to an elastomeric finish that can move with the structure. Good stuff, really, when the opening is a bit fussy and you do not want drips running where they should not. It works for construction work and retrofit work alike, so you can set it in place, hear the job quiet down, and move on with less second guessing.

Key Features:

• One component formula: You apply it straight from the tube, which keeps the work simple when the clock is ticking.
• Non sag body: It stays where you put it, so overhead seams and vertical gaps do not turn into a sticky headache.
• Water based cleanup: The finish is easier to manage, and that calm, low fuss feel is a welcome change on busy sites.
• Elastomeric cure: Once it sets, it leaves a flexible seal that can handle dynamic movement without feeling brittle.
• Retrofit friendly: It fits the kind of repair work that always seems to need one more pass, and it helps you tidy things up with less strain.
