MicroPro Sienna® Treated Wood products are pressure treated with MicroPro® Micronized Copper Azole (MCA) to protect the wood against fungal decay and termite attack. The main ingredient in the preservative system is copper, which has long been known as an effective wood preservative. MicroPro Sienna uses micronized copper coupled with micronized tebuconazole for long-term protection of wood exposed in exterior applications.

Fasteners & Aluminum – MicroPro Sienna treated with MicroPro technology exhibits corrosion rates on metal product similar to untreated wood. Use fasteners and hardware designed for exterior construction that are in compliance with the manufacturer’s recommendations and the building codes for their intended use. MicroPro Sienna Treated Wood products can be used in direct contact with aluminum building products in above ground applications where the wood is not exposed to frequent and prolonged wetting. See Fastener and Hardware Information.
When appearance permits, attach boards bark side up – As a general rule, attach boards bark side up (annual rings arc upward). However, also inspect deck boards before installation and take notice of any knots or defects that could become an issue as the wood dries out and turn that side down. Ensure boards are securely fastened to help prevent warping.

Frequently Asked Questions
Should I apply a finishing product to my MicroPro Sienna project right away?
Yes. Waiting a year or “a season” before applying a finish is a bit of misinformation about treated wood that has been circling around retail yards and contractors for some time. Unless the coating manufacturer stipulates otherwise, you can apply a stain or water repellent to the wood as soon as it is dry to the touch after installation. It will depend on the weather, the exposure to sunlight and how wet the wood was when it was installed (it is saturated with water during pressure treatment).
Why does wood shrink and crack outdoors?
Wood is a natural product and due to its innate characteristics, it shrinks as it loses moisture and swells as it gains moisture. Changes in humidity and temperature can result in warping, checking, and splitting. The development of these seasoning characteristics is normal. Applying a water repellent or stain with water repellent as soon as the wood is dry to the touch will help to reduce the effects of seasoning and weathering.
Why is maintenance required on treated wood projects?
Nothing is “maintenance-free”. Pressure treating protects wood against structural failure due to rot, fungal decay or termite attack. However, moisture, sun, and outdoor conditions will cause wood to show signs of weathering. Natural weathering such as raised grain, splitting, checking, twisting, warping, shrinkage, or swelling occurs in both treated and untreated wood if left unprotected outdoors. To help reduce these effects, apply a high quality water repellent or stain with water repellent as soon as the wood is dry to the touch after installation.
How do I maintain the colour and surface of my MicroPro Sienna project?
A wide range of wood finishing products have been formulated for exterior wood care. As a general rule, you need pigments or colour in the product to protect the wood surface against UV damage. Always read the finishing product label and follow the manufacturer’s recommendations on how and when the product should be applied. For a list of recommended products from popular finishing manufacturers
How long will the MicroPro Sienna colour last?
Left unprotected, the warm brown colour of Sienna will fade to a soft tan or beige and will gradually transition to grey. The length of time will vary according to the exposure to sunlight, the wood species and the application.
