Sound deadener

[Rob Liebbe]

So....what's the best way to remove sound deadener from the floor of a car? Without destroying the car obviously.

I've been told dry ice is the way to go. Freeze it in small sections and hit it w/ a hammer and it shatters.

I have used a heat gun and a putty knife in the past, but it still leaves a residue behind.

My experience is no matter what, there is always some clean up after.

I did part of the CMC car when it was just cold out, so it was brittle. I used a air chisel that I blunted the edge on. Just it started on one edge, and it zips across to the other breaking pieces off.

Then clean with acetone or whatever.

I also used a heat gun, still need to clean.

No matter which method you use, make sure to put a finish coat of Zymol on it

I didn't have much luck with dry ice... ended up going the heat gun route. Paint remover wheel on the grinder worked great taking off the left-over residue.

Rob,

All the dry ice theories are worthless. I used an air hammer, and basically just chiseled it off the floor. But here's the thing: in my Mustang, it was hours of effort for barely two handfuls of stuff. And small handfuls at that.

Since then, whenever people have asked me about it, I told them to go find a quarter pound somewhere else.

Heat gun and a thick putty knife, about 1" wide.

I tried a thin knife but it was to flexible, the stiffer knife worked better.

Cleaned up with lacquer thinner

cold worked on the cars I've helped with - we didn't use dry ice though. Get those cans of compressed air used to clean computers, turn can upside down, spray cold liquid on the area, tap with a hammer, pick up the chunks. Easy cheese.

Heat gun, scrapper and elbow grease.

...scrapper...

That's where Mitch comes in.

Heat gun is working pretty good for me. If you wait for the top layer to just start to bubble on top and then move the heat gun just ahead of the putty knife you can make some really good chunks. I hadn't though about the wire wheel but I tried it yesterday and it works great on the residue. I have gotten a ton of that stuff out already with a little more work to do today.
