Has anyone used it. The roof in my shop is not insulated. It would be pretty simple to spray in some foam and be done with it. 

Any of you gents or ladies have experience with it? Is there a kit you prefer? Is it something I should pay someone to do? 

 

Thanks.

I used the Froth Pak setup and followed directions to a T. It was messy and didn't go on as thickly as I would have liked. It did make a good air seal but is only about 1-2" thick. If I had it to do over again I would probably hire it out. I used a kevlar zip up one piece suit and a full face respirator and taped on nitrile gloves. I came on unscathed but I think there's still some foam on my two-step ladder.

I have spray foam in my workshop. When I was looking, buying the materials and doing it myself was more expensive than paying someone else to do it. After watching them spray my building, I was glad I didn't do it myself.

I asked this many moons ago... like 2012 or something.  The general takeaway I remember was that unless you're investing in some big-dollar equipment, it tends to be tedious, messy, and not very professional.

There might be somewhere you can rent the pro equipment?  Just make sure to buy a borderline-illegal amounts of acetone or appropriate solvent to clean it when  you're done.

For smaller projects, a brand named Kraken makes insulating foam in a can.  It would be tedious and slow, but it's designed for just such DIY things.  I might do this to insulate my camper van.  I don't expect a great R-value, but anything is better than plain steel panels.

I keep thinking of the Youtube channel "just rolled in" and all the cars that people tried to fix with sprayfoam.

Hey, man, you have no idea how many PA rustbelt vehicles I got to pass inspection with spray foam in the holes in the body.  I had an El Camino with swiss cheese rocker panels.  One can of great stuff, a tube of Crest as bondo, and a rattle can of primer later, I had a pretty snazzy set of rockers.  The irony that I used toothpaste to fix my "cavities" was not lost on me.

I did it myself, did my whole finished area of my my basement and all my sills.  Frothpack 650 plus suit plus gun plus tips were 1/3 the cost of hiring it done.  Of course the cost of these damn froth packs has doubled in the past 3 years.

It took about 4 hours to do a basement in a small ranch house.

I had a forced air respirator rated P100, I would suggest something similar if you DIY.

It was summer so we just left all the windows open and evacuated the house with a box fan while it cured.  I had the Rona (the Kung-Flu, the Shanghai Shivers) so I couldn't smell anything, my wife said it wasn't too bad.  

When you DIY, you want the froth packs HOT so they pipe out the whole bottle.  Pro tip is leave the cylinders in their boxes, fill the boxes with foam.  The reaction from the foam kicking will heat the cylinders.

Thanks for the replies. 

I only have about 600 board feet to cover. I'm not sure a company would show up for that small of a job but I'll make some phone calls.
