Ridal Posted November 22, 2011 Share Posted November 22, 2011 My heater core broke so I pulled the dash out. I pulled a bit of the carpet up and found the sound deadening in board form so I want to remove it - it looks heavy. Has anyone come across this type before? Any tips on removal? It seems to be stuck down quite well but I haven't yet had a good go at them. Looks like: Also, does the rubber/fibre mat on the firewall serve any other function than sound insulation? Any tips are appreciated. Quote Link to comment Share on other sites More sharing options...
coldturkey Posted November 22, 2011 Share Posted November 22, 2011 Dry ice is the normal trick I think, freeze it then it comes off in big chunks easily. Havent done it myself personally. Quote Link to comment Share on other sites More sharing options...
Ridal Posted November 22, 2011 Author Share Posted November 22, 2011 I've read that about the tar kind of stuff but this is like a composite board so will hopefully come up without breaking. Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted November 22, 2011 Share Posted November 22, 2011 This is a bunch cleaner than undersell but the dry ice trick still works sweet. Have you tried chipping it away with a decent chisel? if the sound deadening is in good knick(looks mint) it is almost as easy to just use a chisel.

Bling Posted November 22, 2011 Share Posted November 22, 2011 Best solution is dry ice, I think it's like ~$6/kg at BOC, take chillibin. Prop it up against the deadening and give it half an hour or so. Free solution is chisel, but i'd never do that again after using dry ice pellets!

Ridal Posted November 22, 2011 Author Share Posted November 22, 2011 Ok cool. I'll try the chisel first and get dry ice if it's needed. So is the rubber/fluff mat ok to remove as well? Quote Link to comment Share on other sites More sharing options...
beachlander Posted November 22, 2011 Share Posted November 22, 2011 just my 2c but chiseling it is a bitch. it takes ages, you would be much better off doing the dry ice method. Quote Link to comment Share on other sites More sharing options...
Evan Posted November 22, 2011 Share Posted November 22, 2011 the rubber fluff thing is heat shielding isnt it? or maybe its sound as well/instead... i have no idea tbh Quote Link to comment Share on other sites More sharing options...
jakesae101 Posted November 22, 2011 Share Posted November 22, 2011 when i removed a whole heap of that stuff in my car i just used a hammer and 95% of it came out in massive bits and left minimal residue and wiped most of the remains off with white spirits Quote Link to comment Share on other sites More sharing options...
MrMcdoll Posted November 22, 2011 Share Posted November 22, 2011 Me and Tim smashed the sound deadening outta my ta23 with a hammer - most of it was that tar stuff, the firewall bits were like a fibre mixed with tar and harder to get off. On his 240z he had to use a heat gun and scrape that shit out cos it was still softish from 41 years ago!! It left heaps of residue, which will need wire-brushing off. I'd recommend either dry icing it or if you're cheap you could always get a bunch of chilly-bin spec Ice-bags and lay them all over it / whack it with a hammer!

nothingsfree Posted November 22, 2011 Share Posted November 22, 2011 As has been mentioned, dry ice is ya best bet. Just to add to that, Iv done a number of cars with it now, and found the best method is to divide the dry ice up into 4 or 5 plastic shopping bags, rather than just spread it all over the floor. Particularly in your case, as it means you can hang the shopping bags on the firewall to chill it, something which is pretty hard to do with loose pallets..

Ridal Posted November 22, 2011 Author Share Posted November 22, 2011 That's a good idea. I don't think there is any of that composite boarding stuff on the firewall though. It seems to just be rubber with recycled mattress fluff? I'll find out anyway. I'll get the dry ice. Quote Link to comment Share on other sites More sharing options...
Spencer Posted November 22, 2011 Share Posted November 22, 2011 Yea dry ice for that stuff, have done it many times with a scraper/chisel only to wish I went and got some dry ice. Why do you want to remove it? the stuff on the firewall keeps out allot of heat as-well as sound. I'd leave it be unless you are hunting rust or its a go fast car Quote Link to comment Share on other sites More sharing options...
Ridal Posted November 23, 2011 Author Share Posted November 23, 2011 ^I want to go fast. Got the dry ice and went at it. The dry ice sublimed away but I still had the tunnel to do and I found out it was just as easy if not easier to get off without the dry ice. I could get really big bits off because it wasn't so brittle. So far I have removed 12kg and have the boot to go. So I guess the deadening + carpet will be around 20kg.

flyingbrick Posted November 23, 2011 Share Posted November 23, 2011 Your car will feel faster anyway just because of the extra noise. Cool. Quote Link to comment Share on other sites More sharing options...
DavidTheCreator Posted November 23, 2011 Share Posted November 23, 2011 i usually use a hammer and chisel and then paint stripper and a scraper to remove all the small shit Quote Link to comment Share on other sites More sharing options...

Ridal Posted November 24, 2011 Author Share Posted November 24, 2011 Carina wag. I've heat wrapped the headers back to the flange which goes back quite far. It mustn't get too hot otherwise that tar deadening stuff would deform/melt and mine looked to be un-melted? Quote Link to comment Share on other sites More sharing options...
Roman Posted November 24, 2011 Share Posted November 24, 2011 That stuff is so thick, I managed to pull most of it off by unpeeling it off at one corner, and just rolled up into a... roll when it unstuck off the floor. Hah. (On a hot day) Thinner stuff is definitely total win to do it on a cold day with an air powered chisel, smashes the shit out of it in big slabs.
