Product Q&A

Answer:

Both PenaShield and Bora-Care should be applied to untreated, clean, dry wood.  Boracare does not need to be re-applied and lasts for the life of the wood in favorable conditions.  PenaShield must be re-applied every 1 to 5 years to exterior unfinished bare wood surfaces but lasts for the life of the wood for indoor applications and on exterior wood that is painted/sealed.
