Any alternatives for firetaping exterior firewall?

iowaeric

Hi all,

New to the forum but have seen a lot of helpful info as a lurker here. Look forward to getting to know you all better.

We're doing an exterior firewall on a steel building right now as required by city code. Using 5/8" exterior gyp sheathing that needs to be firetaped. Traditionally I'd just firetape it but it being freezing outside now, doesn't seem like a practical option. The closest suggestion I've gotten is to mesh tape it and skim it with durabond, which still doesn't resolve the fact I'm going to waste a lot of mud with it freezing before I can burn through it.

Anyone know of any alternatives for firetaping that are either mudless or practical in below freezing applications? I found a web site for some EZ Tape mudless firetape, haven't priced it out at all yet, has anyone tried that stuff and is it worth it ?

Thanks
Eric

I seen a product in a walls and ceiling mag that they were using for fire taping that looked like a roll of red duct tape that did not require any mud at all and it had a one hour fire rating I'd talk to your supplier to see if they can get it and what it costs

EZ tape is UL approved, but better staple it on. In either cold or hot extreme temps it will simply fall off after a short time.

What is the finished schedule for the exterior firewall? Does it get stucco or efis?

I've used EZ Firetape before taping around a chase for a duct(inspector wanted it, instead of a coat of mud).. Doesn't stick that great inside even, so I can't imagine it staying stuck in the cold.
