Product Description

• Boron, which comes from mines, is processed into a usable powder form that you dissolve in water and apply with a hand-held sprayer. Once you apply it to bare wood, it soaks in. Apply before covering the lumber with anything else, like drywall or insulation.
  
  

Penetration into Wood

• Penetration depends on factors including type and texture of lumber, its temperature, internal moisture and number of applications. Rough dry wood absorbs the borate best.
  
  

Toxicity

• The borate chemicals kill termites, other boring insects and fungi, but present little danger to mammals, including humans.
  
  

Other Benefits

• The borates do not corrode metal fasteners and have no odor. If you keep the treated wood dry, the borate treatment will last a long time, making it very cost-effective. Also, it does not detract from the workability or appearance of the wood.
  
  

Disadvantages

• Water from rain or a leak can dissolve and remove the treatment from the wood. To prevent this from happening to exterior lumber, apply a penetrating water repellent regularly. Interior lumber should stay dry.
