Would multiple coats like this possibly lead to better & deeper boron absorption? I would imagine the extra moisture & time would encourage the boron to penetrate, plus I like that the 1 to 5 mixture remains stable for up to 30 days. I'm looking to slowly mix up 1 to 5 batches & spray suspect areas as I have time or as I find them, though I do have a few areas of active infestation that I will probably immediately hit hard with the recommended 1 to 1 ratio. Does anybody have experience doing this? This is definitely a DIY approach, but I think it would work best for me at my own home.
Boracare will only penetrate up to 8 inches with 2 applications done at the ratios listed on the product label, depending on if you are treating for an active infesation or prevention as well as the type of wood it is being applied. Applying multiple times would not make it penetrate any deeper. You should do your best to only mix enough solution for the job you are doing that day to prevent having to discard any solution. Any unused solution can be dumped out right up against the foundation of the structure taking care not to get it on plants.
