R317.1.1

Section R317.1.1 is titled 'Field treatment' and covers the requirements for maintaining protection of pressure-preservative-treated wood which has been cut, notched, or drilled in a manner that exposes the unprotected wood. When field treatment must be applied and the standard which it must be applied by is established. The purpose of this section is to prevent premature degradation. The cross-referenced standard contains details regarding allowed preservatives and their application, along with other specifications.
