How can I tell if Boracare is being absorbed as needed versus evaporating?
I want to treat my 50 year old tongue and groove ceiling which has some termites. The wood has a transparent stain on it that doesn't seem water repellant. How can I tell if the Boracare is being absorbed adequately? Stripping the entire ceiling or drilling holes throughout would be an enormous job so I would like to try Boracare on a small area and see whether it is going to work before deciding what to do with the rest.
If there is any type of stain on the wood you are treating, Boracare will not absorb properly. The wood will need to be sanded down in order to treat the wood. You do not need to drill holes into the wood in order to apply Boracare. You can either paint it on or use a sprayer. For what you are doing, painting Boracare on the wood would likely be the easiest. Once it is dry, you can apply a second coat for added protection. Once that has dried, the wood can be stained again.
