MicroPro Sienna® Treated Wood

Go Beyond the Structure.

Pressure treated brown lumber with a new generation of copper-based wood preservative, Micronized Copper Azole (MCA), reduces the environmental footprint of MicroPro Sienna to less than half that of traditional treated wood. Specifically formulated to meet CSA guidelines as a wood preservative and specific to Canadian species and use conditions. MicroPro Sienna uses innovative micronized pigment technology to give the wood a warm natural brown tone that enhances its grain and natural characteristics. Designed to meet the style demands of outdoor living, it offers a rich, finished look that complements today’s deck furniture and furnishings. Can also be used in fresh water such as docks and to construct raised garden beds as the MicroPro treated wood process is certified by Scientific Certification Systems, Inc as an Environmentally Preferable Product. 

Protect cut ends, drill holes and other field cuts with a brush-on end cut wood preservative at time of construction. Click here to see our selection for your decking project.

When installing deck boards, should the wood become wet during construction, it is recommended to butt deck boards together. As drying occurs, some shrinkage can be expected. If the wood is dry, allowing for shrinkage is not necessary.

Any exposed wood, pressure treated or not, should be protected from the weather. Application of a quality clear water repellent or stain containing water repellent, will help minimize the cycles of moisture take-up and loss the wood goes through outdoors. Clear water repellent can be immediately applied to your project. If you choose to use a stain which contains a water repellent, ensure the surface of your project is dry before applying.
