Tiger / Fomo Foam and Insul Boards
In my new shop I’ve got a space about 4′ tall on top of the 40′ wall where some 2x lumber rests to support the overhang. Bottom line is OSB with a number of penetrations that need to be sealed. I was thinking about cutting 4″ rigid insulation boards and foaming them into place with Great Stuff. But the video on tigerfoam.com looks like I might be able to spray a layer of Tiger foam and then stick the board into place. This would adhere the board nicely to the OSB and seal the edges at once.
I talked to some spray foam guys but 160 sq ft is too small a job.
Anyone who has used Tiger Foam or Fomo Foam think this would work?
Thanks.
Steve.

With ladder moving and such there might be a couple minutes between some of the spraying. How much time do you get before the nozzle clogs up?Thanks.

Almost an hour. Let the stuff stay on the tip and skin over, that keeps the rest from "kicking" in the nozzle, just peel it away when ya resume.
I had everything ready for an almost continous session tho' just to be safe. Expensive stuff to let go to waste by poor planning.
The fomo in the bead applicater is a bit easier to deal with, I inserted a hardened paneling nail ( just the perfect size for the hole in the brass tip) and wrapped with ele. tape realllllly tight, and it can last for a month. Peel off the tape and pull the nail ( you will need pliers, trust me) and yer foaming again. I found the hardend ringshank nail to be the foolproof way..I used 4 cylinders of that stuff..A log house is just begging for more foam.
Besides my other advice earlier, tie up the dog, children and cats. That foam is like a magnet to things that don't want foam on them...
I was very pleased with the "Handi-foam" from http://www.farmtek.com .

The hoses will last on the tanks for about 2 weeks or so. In the meantime you can just replace the tips, 10 tips come with the hose, which is disposable. The stuff can get everywhere but if you spray with the trigger say halfway you get more control. It is great for insulating everywhere (I've done under enclosed porches, in outside walls when I have replaced exterior claps/shingles). To save on the foam many people spray an inch or so in the wall cavity to seal the cracks etc, and then put regular blanket insulation over the foam when dry.I have insulated alot of my old house with the 600 board foot tanks (tanks about the size of a propane tank). HOWEVER they are much cheaper at EFI in Mass. I have searched around and priced from many places even Ebay. EFI is by far (at least, I have found $100 cheaper than anyone else) . If you are a contractor about $450 a set about $70 for the hose kit. If you are near them in Westborough Mass. you can save yourself the shipping charge with the extra ($40 ?) Hazardous Materials fee.See page 23 on their catalog.http://efi.org/wholesale/2005.pdf
I plan to have everything all lined up and ready for foaming but wanted to know how much time to work, sounds like plenty.Had some Corbond shot in the walk-in attic earlier this year so I hear you about overspray and protection. Luckily the weather was great when they did it and I could open the house because it filled the house with fumes. It was really foggy in the attic. Doubt there are any live mice in the house any more!Thanks.

Fomo Foam says that you shouldn't wait longer than 30 seconds, before you should change tips. I went through a 100 bd. ft. tank in a matter of 20 minutes, not pausing for more than 30 seconds at a time, and still had to change tips a few times b/c of what I perceived as some "cloggage".
I also check the Farmtek site, and found they were $60 more for the same size kit (not sure about shipping) as Fomo Foam.
I might try FrothPak next, as I can buy it locally and save on shipping. The 100 bd. ft. kit went alot farther than I thought it would - I'm looking at being able to seal every nook and cranny of my sill with two 100 bd. ft. kits, and then a few other key areas in my basement.

I think temp and humidity affects the cloggage or tip crusting up. I had no problems at all.
