3.3 Timber preservation (natural solid timber)

3.3.5 Treatment of cut surfaces

Timber which has been preservative treated and cut shall be retreated on the cut surfaces.

Timber should not be resawn, ripped or planed after treatment. Reworking should be limited to cross cutting, boring, drilling and notching; reworked surfaces should be re-treated with two liberal brush coats of a suitable preservative recommended by the manufacturer of the industrial wood preservative. To enable confirmation that re-treatment has occurred a colour tinted preservative should be used; only in situations where colour tinting will affect the appearance of the timber fixed to the home will clear preservative be acceptable.
