I saw this posted here and wondered if any of you have any of you tried one of these borate brews? They are apparently the equivalent of the Tim-Bor and Bora-Care products. I have some fascia that is in the early rot phase and there's only one to two feet of it to do (spread over different spots). I need to be able to do a spray-on procedure to accomplish this due to a recent permanent disability. I know that the proper way to do this is replace the rotting boards but this is a stop- gap measure until I can sort through my finances in the next year or so. Here are the recipes:
This is equivalent to Bora-Care=AE Prepare the concentrate: Mix 1 Gallon glycol antifreeze, 4 1/2 pounds borax, 3 1/2 pounds boric acid. Mix the ingredients and heat till boiling gently. Boil off water until a candy thermometer shows 260=B0F. This removes most of the water of crystallization in the borax. This solution is stable at 40=B0F and has a borate content of 26%. This is equivalent to Bora-Care=AE at about $90/gal. This concentrate must be diluted with an equal volume of water before being applied. Application: Add 1 gallon of water to every gallon of concentrate and stir thoroughly until solution is completely uniform. Always use diluted within 24 hours after mixing. If kept for longer periods of time, the active ingredient can drop out of the solution.
This is equiv. to Tim-Bor=AE...( 6 parts of borax and 4 parts of boric acid) To prepare one gallon of a 10% solution, start with an oversize container (larger than 1 gallon) add 1 lb. of powder to approx. 3 qts of water agitating until the powder has dissolved, then add additional water to end up with 1 gallon of mix. To prepare one gallon of a 15% solution, add 1.5 lbs. of powder, then add the remainder of the water and mix as previously. Approximately 1 gallon of solution will be needed to treat 200 square feet of wood surface area. (Note: solutions should be used immediately and not stored.)
