Kerry from San Pedro, Ca writes
My worry is that the boracare solution is more than 1/2 water, could this cause swelling?
If you are applying to exterior wood like a deck, porch, or fence which is exposed to rainfall, then you would either need to use a water sealant after the Boracare is dry, or you would re-apply Bora-Care after about 3-5 years. We wouldn't be able to tell if your porch floor will swell or not, we would recommend to call Nisus (800) 264-0870 to check with them.
