I'm planning to use Bora-care as a preventive measure on some exterior wood. But I don't understand how to calculate the amount of water and concentrate to use. Here is the label with instructions: https://nisuscorp.com/download/bora-care?wpdmdl=1389&refresh=5f9496ee86a861603573486. For this first project, I have 500 cu. inches of wood (about 5x100x1) and I'd like to use a 5:1 ratio. So how much concentrate should I mix with how much water for that volume of wood?
I know I can mix 5oz of water with 1oz of concentrate or 6oz total, but is that enough to treat 500 cu. inches of wood? What if I want to use the same 5:1 ratio for 1000 cu. in. of wood? or 10,000?
