This new generation of preservative combines the well-known effectiveness of borates with a glycol system that increases the penetration into the wood to enhance the action of the borate. Shell-Guard is a concentrate that is mixed with an equal amount of water, then applied to bare wood with a brush or as a spray. Once in the wood, it will kill those insects that eat wood such as wood boring beetles and termites. It also kills the types of fungi that are responsible for rot and decay. The best thing about Shell-Guard is that one application is permanent as long as the exterior surfaces are maintained with a quality, water resistant stain.

Application

Please Note: Two to four weeks are necessary for Shell-Guard concentrate to fully dry. During this time some of the borate may leach back out on to the surface of the logs. Prior to applying a log stain, any leached borates should be removed by using Log Wash.

  1. Shell-Guard is safe to use according to label directions. It is EPA approved for use in both interior and exterior It is a violation of federal law to use this product in a manner which is inconsistent with its labeling.
  2. Stir an equal amount by volume of Shell-Guard into warm clean water.

  6. Transfer solution to clean spray applicator or bucket.
  7. Apply to bare wood with a brush or a low pressure sprayer.

 

Treating Existing Infestations

  1. For remedial and preventative control of organisms attacking wood, apply the diluted solution of Shell-Guard by brush, spray or dipping until surface is thoroughly wet (one gallon per 108 sq.ft).
  2. Thoroughly soak cut ends.
  3. Application may also be made by drilling and then injecting the solution under pressure into sound wood until run-off is observed from entry/exit holes of infested wood.
  4. Treatment methods as described yields an approximate retention level of .24lbs per cubic ft. boric acid equivalent (BAE) in the outer ¾ inches of the wood.
  5. To minimize borate leaching, apply a water resistant sealer after the surface is dry to the touch. In low temperature and high humidity locations this may take 1-4 weeks.
