If I spray boracare between joist boxes in my basement and I get it on the subfloor would it soak through and harm/warp my finished hardwood floors on the first floor?
Bora-Care can be applied to any raw wood that is not painted, stained or sealed. It will only prevent termites from entering the wood that it is applied to. Most of the time termites would have to eat through the sub-floor to get into the hardwood floors above, but there is no 100% guarantee that the termites will enter this way. Treating the sub-floor would only ensure the termites do not get into the sub-floor. If you want the hardwood floors protected as well, you should treat those also as long as they are unfinished. Bora-Care dries on clear and is used for this purpose all of the time, it will be absorbed into the raw wood and will not warp your hardwood floors.
