How to 'deal with' the sprayed on insulation, on ceiling deck above drop ceilings, when shooting up ceiling wire ? Enough space has to be cleared of the insulation for each Hilti shot to be shot up with Hilti pole gun. Otherwise the insulation will prevent the nail from securely fastening/anchoring the ceiling wire to the ceiling. How to handily remove the insulation from spots to receive ceiling wire, considering that the above-drop-ceiling spaces are typically croweded enough with pipes, ducts, etc, and the ceiling deck is high enough to be out of easy reach?

Shove a piece of pipe up there to cut out a cylinder of insulation? That'd have to be like a 2" pipe though......

We just slam the pole gun up hard into the fire proofing and it works fine, until the gun jambs up with crud.

It is rough on the gun and we have killed vipers on one job, it is still worth while though.

One other thing to consider is the possibility of a back charge for the re-application of the fire-proofing if the building inspector decides to get "technical".

I'd probably just wrap them by hand unless it was just too far up. I'd be wary of scraping the insulation off. Of course...coulda/woulda/shoulda had 'em up already...

I've had this happen, had to go back and fill in around every spot, which sucks
