Timbor should only be used on raw wood that ideally is new. Timbor is not water repellant and it will not take care of any rot or mold on the wood. Timbor will only penetrate 1/4 of an inch into the wood and will leave a visible white residue on the surface. Boracare or Boracare with Mold Care would be your best options. As with Timbor, the Boracare will need to be applied to raw natural wood but it can be old or new. The Boracare will penetrate all the way into the wood and will not leave a visible residue on the surface. If the wood is going to continue to be exposed to the outdoor elements, you will need to seal it with a stain or finish of some sort to protect it. If you do this, the Boracare will last for the life of the wood. Boracare will treat and prevent (depending on the rate you use to dilute it) for wood destroying insects such as powderpost beetles, termites, and carpenter ants, as well as wood destroying fungus/rot. The Boracare with Mold Care will cover all of these same preventative measures and it also kills and prevents mold. Please take a look at the Boracare product label for exact instructions for use.
