IMPORTANT APPLICATION INFORMATION
• Fasteners - Severe Weather
®
offers many benets including signicantly improved corrosion performance. Severe Weather brand pressure treated wood exhibits corrosion rates on metal products similar to
untreated wood.
For interior or exterior applications use fasteners and hardware that are in compliance with the manufacturer’s recommendations and the building codes for their intended use. As with any good
design and construction practices, Severe Weather treated wood should not be used in applications where trapped moisture or water can occur. Where design and or actual conditions allow for constant,
repetitive, or long periods of wet conditions, only stainless steel fasteners should be used.
Fasteners (and other metal products) for use with Severe Weather 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.
- 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 Severe Weather treated wood. Please consult with the individual fastener or hardware
manufacturer for recommendations for use of their products with Severe Weather treated wood. In addition, carbon steel fasteners may be used for interior, above ground, weather-protected applications such
as sill plates, interior framing and interior trusses.
• 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.
•
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.
• 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.
• Apply a weather-resistant nish - 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 Severe Weather 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 rst 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.
If the Severe Weather 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.
Severe Weather products, as described in this warranty, are treated with Propiconazole, Tebuconazole, and Imidacloprid (PTI). Lowe’s and the gable design, Top Choice

IMPORTANT INFORMATION
• 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 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.
• Disposal Recommendations - Preserved wood may be disposed of in landlls or burned in commercial or industrial incinerators or boilers in accordance with federal, state, and local regulations.
• If you desire to apply a paint, stain, clear water repellent, or other nish to your preservative treated wood, we recommend following the manufacturer’s instructions and label of the nishing product. Before
you start, we recommend you apply the nishing product to a small exposed test area before completing 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
Specications (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 www.epa.gov.
