Dry ice vs factory floor tar

[Harpo]

Well I spent four hours the other day with very little results trying to chip away at my floor tar. Jim tweet and others had suggested dry ice so I gave it a try

The size of this is quite small, I was expecting to get small ice cube size pellets.

I was expecting to see that you blasted the area with dry ice, not froze it so it would chip off easier...what ever works, though.

I found that a little heat from heat gun and this airl chisel works very well on floors

[Harpo]

the pellets are too large for my sandblaster so this passive method was the best that I got. I am using this in conjunction with a multi tool. Some sections came up in large 3x3 but others came up in much smaller pieces

I just did this... removed entire floors of tar. I pointed a kerosene heater, salamander, at the floor to heat it. A piece of hardwood floor cut in a chisel like point worked as a scraper.

I've never seen someone lay ice on top of the tar... that's.... different.

I buy two boxes of dry ice pellets. Pour one box on each side. Let sit about 20 minutes. The tar will fall off in seconds and leave a clean surface behind

I used a heat gun set on high. It takes a little while for the tar to soften but once you get a corner to lift it comes off like taffy. I also use a heat gun on the undercoat/shutz. Same thing once the shutz heats up it comes off in ribbands. Follow with a wire wheel to clean up and residue.

I never tried the dry ice trick.

Ive done what Jim did there. It works amazingly well. Zero scraping, smack with a rubber mallet and it all comes up like toffee.

Yep!!! Whack from the bottom side of car with rubber mallet

[Harpo]

I will try the rubber mallet after dinner. Oops that won't work because my scissor lift is under my car

[Speed metal]

I beat on mine from the topside It works mint

getting ready to do this. was about to search for a thread.

seems I read in some dry ice thread they also poured alcohol into the mix. seems the idea was to help transfer the dry ice cooling better. but when I consider pouring a couple pints of alcohol in there the risk of fire hazard comes to mind.

car is about to go on a rotisserie. once I do the dry ice and beat that stuff loose, just rotate the car and dump it all out.

glad I saw this.

I'd like to see the before and after pics of this process.
I'm indifferent about removing the sound deadening material on my floorboards, but if its really that easy, then I might just have to do it.

OH and with the heat gun and scraper, how long did that take?

wondering if the dry ice helps remove any of the old undercoating from the bottom.

car is getting blasted down to the metal.
