Jronman Posted April 8, 2017 Report Share Posted April 8, 2017 What is the best way to remove spray foam insulation? The guy I was working with yesterday asked another worker and he replied "lol there is no way". We tried hammers, flat bars, paint scrapers. He tried a chisel and a drywall saw. I tried a recip and a wire. Quote Link to comment Share on other sites More sharing options...
rrmccabe Posted April 8, 2017 Report Share Posted April 8, 2017 Where is it used? Does it have wiring in it? Quote Link to comment Share on other sites More sharing options...
SetBuilder Posted April 9, 2017 Report Share Posted April 9, 2017 Google hot wire or hot knife foam cutting. Works great on foam blocks, I have never used it on spray foam, but it should work fine. Quote Link to comment Share on other sites More sharing options...

We actually have it at work .. I never knew they made a sawzall blade like that. We always have the metal shop weld a bunch together... The round tool with handle is typically a sculpting tool.

The whole wall from floor to ceiling is insulated with it except for a window, door, studs, electrical boxes and a couple wires. I can't remember if it was a 2x6 wall or a 2x4 wall. I thought about a hot foam wire but not sure if we got one at work. Turns out my boss came by, saw the insulation, and decided we didn't have to worry about the insulation. Wall is coming out anyways. 1 Quote Link to comment Share on other sites More sharing options...

Conductor562 Posted April 10, 2017 Report Share Posted April 10, 2017 Here's how I'd like to remove it: Unless you're in Cali or Maryland and you've got $1600, you can be the coolest guy I know. http://www.popularmechanics.com/military/weapons/a16651/x15-flamethrower-consumer-flame-thrower/ Wonder if I could write that off on my taxes? 1 Quote Link to comment Share on other sites More sharing options...
Bremon Posted April 26, 2017 Report Share Posted April 26, 2017 Well I've sprayed over 100,000 gallons of spray foam and used all the methods mentioned minus the blow torch. They're all shit. Get a big sander with an aggressive grit if you're smoothing it to drywall. For full removal...demo the walls lol. 1 Quote Link to comment Share on other sites More sharing options...
Jronman Posted April 26, 2017 Author Report Share Posted April 26, 2017 Full removal was what we were attempting... without taking down the wall. Quote Link to comment Share on other sites More sharing options...

Jronman Posted April 26, 2017 Author Report Share Posted April 26, 2017 what is this nightmare fuel? Does it perform as well as a Milwaukee? 1 Quote Link to comment Share on other sites More sharing options...
Bremon Posted April 27, 2017 Report Share Posted April 27, 2017 It's the horrifying tasks you're sometimes faced with during the day that haunt your dreams and keeps you up. Unless Milwaukee is having an insane promo I don't know about then it definitely works better than Milwaukee ?. Quote Link to comment Share on other sites More sharing options...
