The only product I would recommend is BoraCare. This product will protect the wood permanently. Apply to the point of runoff to bare wood. It will not penetrate stain, paint or varnish.
1 Gallon will mix with 1 gallon of water to make 2 gallons of dilution. This will treat an area 800 square feet. If you need less, then only mix what you need. This is the smallest container it comes in.
