Whatever you build with YellaWood® brand pressure treated wood will last a long time. So, it makes good sense to build in a craftsman-like manner. Here are some helpful tips to make your job easier and look better.
1) Use corrosion-resistant fasteners
YellaWood® preserved wood products are designed for long-term performance in outdoor applications and, therefore, require high quality, corrosion-resistant nails, screws and other fasteners. For fastener specifications and a list of recommended hardware click here.
2) When appearance permits, attach boards bark side up
As a general rule, attach boards bark side up (annual rings arc upward, like a rainbow) 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.
3) Use carbide tipped saw blade to cut preserved wood
4) 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.
5) Deck board spacing
Should the wood be 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.
6) Fence picket spacing
When building a stockade fence it is equally important to butt wet pickets together. Just as with deck boards, some shrinkage will occur as the pickets dry. By butting the pickets together during construction, you will minimize the gap left between the pickets after they dry.
7) 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. Always follow manufacturer's recommendations.
8) Apply a weather-resistant finish
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 that contains a water repellent will help minimize the cycles of moisture take-up and loss the wood goes through outdoors. For maximum protection, one of these products should be applied as soon after construction is completed as possible.
First, thoroughly clean your project. A clear water repellent can then be applied to your project. If you choose to use a semi-transparent stain that contains a water repellent you need to first check that your project is surface dry to assure proper penetration of the stain. This can be tested by sprinkling a few drops of water on the wood surface. If the wood readily absorbs the water, apply the semi-transparent stain immediately. If the wood does not absorb the water, wait several days and retest. Or immediately apply a clear water repellent and wait approximately eight weeks and then apply your chosen color of semi-transparent stain.
If you've chosen to build with a product that contains a factory-applied water repellent, an oil-based stain can be applied in 30 to 60 days and water based stains can be applied after six months. Check that the wood is surface dry before applying stain.
For the best results, water repellents should be applied annually and stains should be re-applied as needed. In all instances follow the manufacturer's directions when applying water repellents or semi-transparent stains which may contain water repellent.
Mold growth may occur on building products, including untreated or treated wood. To remove mold from a treated wood surface, mild soap and water is typically used.
The preservatives in YellaWood® brand products penetrate deeply into and will remain in the wood for a long period of time. However, some preservative may migrate from the preserved wood into surrounding soil over time and there may also be incidental contact with the skin during construction or use.
Handling and Use Recommendations
- Consult the end tag to determine which preservative or preservative system was used in the treatment of that particular product. Micronized copper treated products may be used in direct contact with aluminum building products when limited to code-compliant construction applications that provide proper water drainage and do not allow the wood to be exposed to standing water or water immersion.
- Use fasteners and other hardware that are in compliance with building codes for the intended use with micronized copper treated products.
- Do not burn preserved wood.
- Wear a dust mask and goggles when cutting or sanding wood.
- Wear gloves when working with wood.
- Some preservative may migrate from the treated wood into soil/water or may dislodge from the treated wood surface upon contact with skin.
- 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 when 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.
- 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 ensure it provides the intended result before proceeding.
- 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 www.epa.gov.
- 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.
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.
