• When appearance permits, attach boards bark side up- As a general rule, attach
boards bark side up (annual rings arc upward) to reduce cupping; however,
the best face should be placed up when a defect of the wood is apparent.
Fasten thin boards to thicker boards to maintain structural integrity.
• Drill pilot holes- Drill pilot holes especially when nailing or screwing near the
edge or end of a board. Pilot holes will help minimize splitting.
• Use an endcoat preservative- Brush-on endcoat wood preservative is
recommended on all saw cuts and into drill holes during construction of
wood projects. Also apply on areas where moisture can collect. Follow
manufacturer’s recommendations.

- Other fasteners and hardware as recommended by the manufacturer
There may be additional products (other than stainless steel or hot-dip
galvanized) which are suitable for use with MicroPro AC2 treated wood.
Please consult with the individual fastener or hardware manufacturer for
recommendations for use of their products with MicroPro AC2 treated wood.
• Apply a weather-resistant finish- Any exposed wood, pressure treated or not,
should be protected from the weather. Application of a quality clear water
repellent or semi-transparent stain, which contains water repellent, will help
minimize the cycles of moisture take-up and loss the wood goes through
outdoors. First, determine if your MicroPro AC2 product has been pressure
treated with a factory applied water repellent by looking at the end tag. If not
factory water repellent treated, thoroughly clean your project with a deck
cleaning product. Clear water repellent can be immediately applied to your
deck or other project. If you choose to use a semi-transparent stain which
contains a water repellent, you need to first check that your project is surface
dry. Either wait until the surface is dry or immediately apply clear water
repellent and wait approximately 8 weeks and then apply your chosen color
of semi-transparent stain.

• Fasteners- Tests show that MicroPro AC2 pressure treated wood has corrosion
rates on metal fasteners and hardware similar to that of untreated wood. Use
fasteners and hardware that are in compliance with the manufacturer’s
recommendations and the building codes for their intended use.
Fasteners (and other metal products) for use with MicroPro AC2 preserved
wood products include:
- Stainless Steel
Stainless steel fasteners and connectors are recommended for use with treated
wood in other severe exterior applications such as swimming pools, salt water
exposure, etc. - Type 304 and 316 are the recommended grades to use.
If the MicroPro AC2 products contain a factory water repellent, an oil based
stain can be applied in 30 - 60 days and water based stains can be applied after
6 months. Check that the wood is surface dry before applying stain. In all
instances follow the manufacturer’s directions when applying water repellents
or semi-transparent stains which may contain water repellent.
• Deck board spacing- Should the wood become wet during construction, butt
deck boards together. As drying occurs, some shrinkage can be expected. If
the wood is dry, allowing for shrinkage is not necessary.
MicroPro AC2 pressure treated wood products are treated with Micronized Copper Quaternary Compounds.

Important Information
• Tests show that MicroPro AC2 pressure treated wood has corrosion rates on metal
fasteners and hardware similar to that of untreated wood. Use fasteners and hardware
that are in compliance with the manufacturer’s recommendations and the building
codes for their intended use. When using aluminum products in conjunction with
MicroPro AC2 treated wood, refer to the MicroPro AC2 Fastener and Hardware
Information Sheet for additional information.
• Do not burn preserved wood.
• Wear a dust mask and goggles when cutting or sanding wood.
• Wear gloves when working with wood.
• MicroPro AC2 preservatives penetrate deeply into and will remain in the wood for
a long period of time. Some preservative may migrate into soil/water or dislodge
from the wood. Incidental contact with skin during construction or use may occur.
Wash exposed skin areas thoroughly.
• All sawdust and construction debris should be cleaned up and disposed of after
construction.
• Wash work clothes separately from other household clothing before reuse.
• Preserved wood should not be used where it may come into direct or indirect contact
with drinking water, except for uses involving incidental contact such as fresh water
docks and bridges.
• Do not use preserved wood under circumstances where the preservative may
become a component of food, animal feed, or beehives.
• Do not use preserved wood as mulch.
• Only preserved wood that is visibly clean and free of surface residue should be used.
• If the wood is to be used in an interior application and becomes wet during
construction, it should be allowed to dry before being covered or enclosed.
• Preserved wood may be disposed of in landfills or burned in commercial or industrial
incinerators or boilers in accordance with state and federal regulations.
• If you desire to apply a paint, stain, clear water repellent, or other finish to your
preservative treated wood, we recommend following the manufacturer’s instructions
and label of the finishing product. Before you start, we recommend you apply the
finishing product to a small exposed test area before finishing the entire project to
insure it provides the intended result before proceeding.
• Projects should be designed and installed in accordance with federal, state, and
local building codes and ordinances governing construction in your area and in
accordance with the National Design Specifications (NDS) and the Wood Handbook.
• Mold growth can and does occur on the surface of many products, including
untreated and treated wood, during prolonged surface exposure to excessive moisture
conditions. To remove mold from the treated wood surface, wood should be allowed
to dry. Typically, mild soap and water can be used to remove remaining surface
mold. For more information visit
