Default Fire stop foam

These bottles are great and worthless at the same time.

Sometimes you need to fill in 2 small holes for inspection and then junk the whole bottle.

I tried to use a bottle for the second time today which still had 95% fill... it ended up everywhere a total mess... amazingly it did the job but barely..

Am I missing something here ? There has got to be a better way...

There are many tricks -- recorded on YouTube -- to save partial cans.

You might also look into purchasing fire stop as PUTTY PADS.

They are perfect for tiny holes.

The pads are great , but wouldn’t be efficient for some jobs. I’ll check out the videos

@WronGun, did you ever try the putty sticks? You can buy it in bricks like duct seal or packages that look like big sausages. I only use the pads for wrapping boxes in a firewall.

For anyone who's seen a fire take out something substantial, some sealant is a rather dubious remedy

Spray bottle or spray can ?? normally I used fireproof chalking in chalk gun that useally last longer and you can seal up the tip with etape and when you need it just peel it off and off you go with it.

We get the fire rated foam for the re-usable guns. They have a knob you turn to shut the air off to the cans.

The re-usable guns with the disposable tips and a can of cleaner work perfectly.

The job I'm currently on doesn't allow the use of fireblock foam. Just fire caulk, it gets messy and spendy when the sheet rocks decide to leave a giant hole around Smurf/conduit/wires.

The fire stop foam cans make short sweet work of the penetrations above the ceiling tile into and out of tenant spaces. Love the stuff better than plain old expanding foam. And so do electrical inspectors during open ceiling inspections. After seeing that they leave you alone pretty much.

If that's the case let them close it up with compound.

Sometimes it's easier to do it yourself and know it's done than waiting and waiting... And waiting for them to do it. Also the company that initially made the whole failed and the GC hired a new company so they don't see it as their problem/priority.

I worked for a company that in all contracts would state that the GC was required to fire seal all and everything necessary. They would take some money out of the bid, but the amount of labor time and materials saved was much greater. The GC would just sub it out to a company who would come in for one day a week and just spend that entire day sealing everything.

The last job the company was on was like that. Why can't it just be a standard?

It can be a standard- Get your company to include it in all their contracts.

Our company always excludes firestopping.
