3M 7100006311 – Frequently Asked Questions

1) What fire rating does 3M Fire Barrier CP 25WB+ sealant carry for through-penetrations?
CP 25WB+ is firestop tested for through-penetration applications up to 4 hours in accordance with ASTM E814 (UL 1479) and CAN/ULC-S115. It is also fire resistance tested for static construction joint systems to ASTM E1966 (UL 2079). The ULC listing matters if you are working on a Canadian job where provincial code calls for CAN/ULC-S115 rather than the UL equivalent.
2) Can 3M CP 25WB+ be used in both floor and wall penetrations, or will it sag out of an overhead joint?
It works in both. CP 25WB+ is sag resistant, which is what lets it hold in wall penetrations and floor applications without slumping out of the opening while it cures. That is the practical reason to pick this over a runnier sealant when you have mixed conditions on the same floor of a building.
3) If I have to add another cable through a penetration I already firestopped, do I have to cut the sealant out?
No. CP 25WB+ is re-enterable and repairable, so you can cut in, pull or add a cable through the sleeve, and reseal with fresh sealant rather than demolishing the whole penetration. That is a real advantage for low-voltage and data contractors who come back to the same riser repeatedly.
4) Should I buy the cartridge or the 2 gallon pail of 3M Fire Barrier CP 25WB+?
Two container sizes are offered: a 10.1 fl oz cartridge (MPN 7100137423) that fits a standard caulk gun for individual penetrations and punch-list work, and a 2 gallon pail (MPN 7100006311) for pumping larger volumes, long head-of-wall joints, or high-count penetration jobs. Same sealant either way, so the choice is purely about how much you are placing and how you intend to dispense it.
5) Can 3M CP 25WB+ firestop sealant be painted over after it cures?
Yes. CP 25WB+ is water based and paintable, so in finished corridors, tenant spaces, and occupied areas you can paint the patch to match the wall. The sealant itself is red, which is useful for inspection because a fire marshal can see at a glance that a rated sealant was used before the wall gets painted.
6) Is water-based firestop sealant like CP 25WB+ the right choice, or should I use an intumescent putty or wrap instead?
A water-based sealant such as CP 25WB+ is what you reach for on gunnable penetrations and static joints, cable and conduit through gyp or concrete, where you can place a bead and tool it. Putty pads and wrap strips are different tools for different conditions: pads for box openings, wrap strips for combustible plastic pipe that needs to be choked off as it melts. CP 25WB+ covers through penetrations to 4 hours and static construction joints, not moving joints.
7) Does 3M CP 25WB+ help with sound transfer between units, or do I need a separate acoustical sealant?
The sealant helps minimize sound transfer, so a penetration firestopped with CP 25WB+ is also doing acoustic work at that opening. In multi-family and hotel construction, where the same wall is both a rated assembly and a demising wall between units, that means one product at the penetration instead of two.
8) How many 10.1 oz cartridges of 3M CP 25WB+ come in a case?
The 10.1 fl oz cartridge of CP 25WB+ is packed 12 per case, which is the normal buying unit for electrical and drywall crews working a floor at a time.
