Will Bora-Care treat a log house after it has been treated with an exterior treatment about 2 years ago?
Bora-Care will not penetrate through any type of paint, stain, sealant or other product. It is true that stains and sealants will wear off over time, but it is hard to tell how much is left and how much Bora-Care will be able to penetrate through. Some of our customers treat anyways and feel it is better that some make it through and some not, than not to try to treat at all. So this is a decision you have to make on your own.
