Title: Removing soudn deadener
Post by: NSharpley on February 17, 2019, 07:25:31 AM
Hi All,

I read a post in the US that using dry ice to get rid of the sound deadener makes the task quite easy.

The ice freezes it and makes it very easy to chip away after 10 minutes or so.

Anyone have any thoughts on this approach?

Any undesirable side effects you can think of?

Apparently it works in Australia, too.

Have no direct experience in the removal process, but based on the attached Youtube video, using dry ice to freeze the bonded surface would appear to be the simplest method. Only aspect of the process that you need to be mindful of is to treat areas were the paint may have also lifted to prevent future corrosion.

Yes, I've done it. No side effects other than wishing I'd known about it sooner as it's a far cleaner way to remove the stuff than scrapping or solvents.

I found an old shopping bag best as they're super thin so the ice freezes faster (if you have any left).

I used a 1" paint scraper from Bunnings to chip it up.
Surprisingly it left the original primer on the floor pans.
