Removing sound deadening using dry ice method
Hi guys, just wanted to share my experience using the dry ice technique to remove sound deadening.
A bit of background: I use my car mainly for lapping days, but I also drive it on the road to get to the track. I'm not really looking to be competitive, just making the car as fun as possible.
Next step for me is adding a roll bar, which will be built in march. In preparation for this, I stripped the interior and tried to see what will go back, and what comes out permanently.
A no brainer was the sound deadening that needed to be partly removed anyway for the cage to be welded, so might as well get rid of it completely.
The prospect of a low effort / high reward was pretty appealing, so I gave it a shot!
I bought dry ice from Linde (formerly praxair) in montreal. It was about 50CAD for a bag of 12kg (plenty to do the whole car). I also purchased 2 bottles of isopropanol alcohol.
It's also useful to have a cooler to transport the ice, a bucket, winter gloves, a hammer and a scraper / crow bar.
I added 1/4 of the dry ice bag into the bucket, crushed it with a hammer and added some alcohol (the smoke show is pretty cool :P)
I poured the content on the sound deadening and spread it evenly using my winter gloves (note that dry ice is -109°C, so never touch it with bare hands).
Then it's a game of listening to whole thing crack for a minute or two and hitting it / scraping it with a crow bar.
I had instanced where the sound deadening shattered into chunks, other time the would de-laminate in 1 square foot pieces.
once done, I would push the dry ice to another area and add more if needed.
The whole car took me about an hour to do, and the total weight is roughly 20lbs.
I would highly recommend it to anyone that has access to dry ice locally!
Here's what it looked like during and after the dry ice (note that I didn't clean of vacuum anything at that stage, this is just the result of the dry ice).
Here's the video that inspired me to give it a try:
