I have seen Canadians buy and use a " kit" of spray foam in a box, with a wand to do walls, etc with foam. I can't seem to find a place that sells these . All I can get are cans similar to "Great stuff" .
Obviously the pros have this stuff, but I will need to do it myself.
House built in 1862 ( Lincoln was President)
Had vermiculite put in in the 50's
All that fell down .
I have 2 wall I want to do from inside with holes in the wall at locations.
These walls are original with plaster , slats, lead paint
So I am not ready to tear into that mess.
Thoughts on where to buy ? I know I can rent a dry insulation thrower.
Thanks!
