I need to spray Bora-Care on the sleepers in my 1870 barn. Most of the beams still have their bark on. Moisture content is quite low on most. Will the Bora-Care penetrate through the bark and into the wood? As well most of the sleepers are larger than 8-10
Bora-Care will not penetrate through logs that still have bark on them. The bark will need to be removed from each log for an effective application. If the sleepers are 8-10" in diameter, this will require 2 full applications. The second application will need to be applied once the first application has dried.
