Edwin from San Diego, Ca writes

If wood is already painted can it be treated with Boracare injected through holes drilled into the wood?


Yes, you can still treat wood that is painted with Bora-Care by injecting it, however it does require quite a few holes.  You should drill holes every 6 inches apart in a diamond pattern into the center of the wood and inject the Bora-care into all of the holes.  It helps to drill at a downward angle so the Bora-care does not run out of the holes due to gravity.  So, you would drill holes in the center of the wood, and then also another row of holes near the top and the bottom which will form a diamond pattern.
