Advanced Treating Technology

MicroPro® preservative technology is a revolutionary way to pressure treat wood for decks, fences, landscaping and general exterior construction uses. MicroPro preservative technology meets Canadian Standards Association (CSA) standards as a wood preservative that has been formulated especially for Canadian species and use conditions. Wood treated with MicroPro can be used above ground, in ground contact and in fresh water.

The MicroPro preservative technology is a waterborne, micronized copper azole (MCA) system developed to provide long-term protection for wood exposed in exterior applications. The MicroPro system is based on the well-established effectiveness of copper combined with an azole compound and is applied to wood by pressure treatment. Copper and azoles are effective fungicides and termiticides, protecting the treated wood from fungal decay and termite attack.

The preservative protection of MicroPro Sienna Treated Wood is backed by a residential limited warranty against fungal decay and termite attack. See warranty for details.

MicroPro Sienna Treated Wood products are produced by independently owned and operated wood preserving facilities.
