Preventative treatment on timber-frame barn
We are replacing the siding on a timber frame barn which has 12"x12" uprights, 8x8 and 4x4 stringers/braces. Before we put up the pre-primed yellow pine siding, we want to apply preventative BoraCare. How long do we have to wait before mounting the siding? Is the 5:1 the right dilution for prevention? Does it make more sense to use a roller or sprayer? We will be working from a lift and will have easy access to 3 faces of the wood (The interior face is a bit inconvenient from the exterior of the building.) If any areas show an active infestation, do we just switch to the 1:1 dilution and apply as above? Thanks!
Actually the 5:1 Boracare treatment is only if you wanting to prevent against drywood termites and powder post beetles. If you live in an area that has subterranean termites which you probably do since subs are much more common than drywood termites and powder post beetles, you should use a 1:1 treatment for treatment of existing termites and for prevention of subterranean termites. We always recommend a 1:1 treatment because then you have the highest level of protection no matter what you are dealing with or what is in your area. Also, if there is something active in the wood that you don't know about, the 1:1 treatment will take care of it. Most people apply using a sprayer but it is completely up to you. Typically you only have to wait about 4 hours before mounting the wood you treated. It does dry quickly most of the time.
