3M 7100134123 – Frequently Asked Questions

1) What are 3M Fire Barrier Moldable Putty Pads MPP+ used for on an electrical job?
They are a pliable one-part intumescent firestop material for wall openings and through penetrations. The usual job is wrapping the back and sides of an outlet or switch box in a rated wall so the membrane penetration keeps its rating, and they also work on cable and pipe through penetrations. No mixing, no tools, no caulk gun; you press them on by hand.
2) Will one 7 x 7 inch putty pad cover a standard single-gang outlet box?
Each pad measures 7 x 7 inches (178 x 178 mm), which is sized to be molded over a single-gang box and folded onto the back and sides. For larger multi-gang boxes you combine pads, since the material can be cut and pieced together by hand.
3) What fire rating do the MPP+ putty pads carry?
The MPP+ pads are rated up to 2 hours, and they are firestop tested for through penetration and membrane applications for up to 4 hours in accordance with ASTM E 814 (UL 1479). Which duration applies to your opening depends on the tested system you are building to, so match the UL system number on the drawing.
4) Are these putty pads safe to put directly on cable jackets and metal boxes?
Yes. The material is non-corrosive to metal and compatible with synthetic cable jackets, so it can sit against a steel box and against THHN or similar jacketed conductors without attacking them. It also adheres to a wide range of construction materials.
5) Do 3M MPP+ putty pads also stop smoke and drafts, or only fire?
They provide a draft and cold smoke seal in addition to the firestop function, and help cut noise transfer between rooms through box openings. That matters in hospitality and multi-family work where sound flanking through back-to-back outlets is a complaint generator.
6) Can 3M MPP+ putty pads be used in a wet or below-grade location?
No. The pads are not water tight, so keep them to dry interior wall assemblies. For a penetration exposed to standing water or weather you need a sealant rated for that condition instead.
7) How many putty pads come in a case of 3M 7100134123?
Part 7100134123 is a 20-pad case of red 7 x 7 inch MPP+ pads. For a fit-out, figure roughly one pad per single-gang box, so a case covers about 20 standard boxes.
8) Why are the 3M firestop pads red?
The red color is deliberate on firestop products so an inspector can see at a glance that a box or penetration has been treated. On MPP+ the pads are red, which makes a missed box obvious during walkthrough before the wall closes.
