Simply by reading the end tag on each piece of lumber, the end user will be able to determine if a product is approved for use in "above ground" or "ground contact" applications.

Ground contact means that the product is approved for use in applications that require the component to be either placed on or directly in the ground (fence or deck posts; landscaping). Ground contact also applies to products used in above-ground applications when the components are subject to hazards comparable to ground contact or are used in applications that are difficult to maintain, repair or replace and are critical to the performance and safety of the structure (deck joists, beams, ledger boards, etc.)

MCA can be placed in contact with aluminum in code-compliant construction applications that provide proper water drainage and do not allow the wood to be exposed to standing water or water immersion.

Selecting the right fasteners will help ensure the longevity of your project. Use hot-dip galvanized or other fasteners as required by local building codes. Galvanized and stainless steel fasteners are corrosion-resistant and will not stain your project. Follow the manufacturer's recommendations.

Yes. Scientific studies have proven that any copper that may migrate from the treated wood becomes biologically inactive, thus causing no eco-toxic or other environmental impacts.

Perform the following test to determine if your project is ready to paint or stain: Place a few drops of water on the area to be coated. If it beads up, it is too wet to coat, and you'll need to wait. If it absorbs the water readily, it is ready to coat. If you want to paint your project, use an oil-based primer and a high-quality acrylic (latex) paint. If you want a stained look, a high-quality stain is recommended. Always check with the manufacturer before applying and follow their instructions. 

Preserved wood may be disposed of in landfills or burned in commercial or industrial incinerators or boilers in accordance with federal, state and local regulations.

Even though no maintenance is needed to retain the treated lumber's resistance to rot, fungal decay and termites, a regular maintenance program, including a periodic coating of water repellent, will help maintain the appearance of your project. This will also protect against splitting and checking.
