For optimum penetration of the product into the wood and the quickest protection/elimination from insects, the Boracare needs to be applied to all sides, or at least as many sides as you can get to of the wood, no matter the depth. When it comes to protecting against wood destroying insects like termites you do not want to leave room for an inconsistent coverage that could allow more damage to be done.
