Repairing Damaged Spray Foam
I have closed cell spray foam covered with monokote thermal barrier spray in my 100-year old basement in zone 6. It was recently dug into to access the copper pipe (see photos). Now the vapour/thermal barrier is not continuous. Any tips on how best to fix? I know I should have a vapour barrier underneath if I plan to spray over the open cell canned spray. I’ve looked at the 475 building performance products (vana tape, caulk etc), but not sure it will work with my uneven surface and crevices.
