Q&A Home

Adam from Kansas writes,

Will insulation inside wall voids hinder the effectiveness of Boracare?

I do not want to remove all of the drywall in order to remove insulation to treat the wood. Will pumping foam into the wall voids through small holes work?


You can foam Boracare 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.
