I'm new to posting, but thought some might use this. I have been useing these mixtures for some time with great results. I mill a lot of dead and used lumber.They offer great protection at a low cost. I buy the boric acid as roach poison at the local home store for about $2.50 a pound. Do a Google search for Chemotherapy for wood rot and you will find more info. I usualy spray it on with a hand sprayer or paint it on old beams. It is a great insect and mold control. It also dosn't affect the color or finishing of the wood.

20% Borax(laundry detergent), 15% Boric Acid, 65% Water. Boil until boric acid dissolved. Should use soon or boric acid will re crystalize. I boil outdoors on old BBQ grill, due to smell. Add 50% glyco antifreeze in place of water if mold or rot are a problem. Comparable to Tim-Bor, Ship-Bor or Bora-Care only at a small fraction of the cost.
