I will be pulling back the insulation and spraying bora care in my crawl space against the rim joist and floor joists and plywood floor. I will do this 2 feet in from the outside wall of the house. Can I put the insulation back in between the floor joists immediately after spraying Bora-Care?
The insulation should be removed so that the Bora-Care can be applied directly to the wood. It is safe to place back once surfaces treated are completely dry. You can foam Bora-Care into the wall voids. The insulation may soak up a bit of the applications but here is how the pros handle it: You will need to use a stud finder to locate each stud. You should then drill a hole at the top of the wall on either side of each stud and you should drill a second set of holes at the bottom of the wall on either side of each stud. You will apply the foam using the top holes and you will know the foam has successfully coated the wood when it comes out of the bottom holes on either side of the studs.
