When applying bora-care in drilled holes behind drywall is it best to spray or foam?
Foaming is the preferred method when treating voids. To foam a product you need a poly foamer to apply the foam and our ProFoam Foaming Concentrate which is an expanding liquid you need to mix with the solution. You would mix the Bora-Care with water in a one gallon poly foamer, then pour in the foaming agent, then mix it all together and pump up the poly foamer. You are now ready to foam voids.
