MicroPro® preservative technology is the most advanced wood treatment process for wood used in 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. MicroPro Sienna Treated Wood can be used in residential applications above ground, in ground contact and in freshwater contact. Usage is indicated on the end tag attached to the treated lumber.

MicroPro Sienna is no more corrosive to metal products than untreated wood. Fasteners and hardware should be rated to the environment and conform to building codes. Aluminum building products may be placed in direct contact with MicroPro Sienna Treated Wood used indoors or in above ground exterior applications where the wood is not exposed to frequent and prolonged wetting, such as decks and fencing.
