I am redoing the wiring in my house by fishing it through the walls and attic making small cuts where needed to pull it through. The outer walls have foam insulation and some of it has crumbled to dust while working and some of it has been cut out and saved. What is the best way to repair the insulation without ripping out the drywall? I have thought about putting the cut out stuff back and using canned spray foam do do the rest. Will this work?
