Care & Usage

Hi-bor® Fasteners and Hardware Information

Hi-bor® Products may be placed in contact with aluminum.

Fasteners used with Hi-bor® Borate Pressure Treated Wood Products should be compliant with building code recommendations for the intended use.

Check with local building authorities and building codes regarding acceptability of fasteners and fastening requirements.

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, Hi-bor® 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.

Important Information

The following precautions should be taken both when handling the preserved wood and in determining where to use and dispose of it. Many of these precautions also apply to untreated wood and other building materials.

  • Job site storage — intended for interior use only — store off the ground and cover to protect from water and allow for ventilation.
  • During construction, if the wood should become wet, it should be allowed to dry before being covered or enclosed.
  • Do not burn preserved wood.
  • Wear NIOSH N95 dust mask and goggles when cutting or sanding wood.
  • Wear gloves when working with wood.
  • Do not use preserved wood as mulch.
  • 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.
  • Fasteners and other hardware must be compliant with building codes. Refer to the [Fastener and Hardware Information page] (jump link to ‘Care & Usage’) for additional information.
  • Disposal Recommendations: 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.
  • When products are used in weather protected exterior applications (such as fascia board), it is recommended that the product be continuously protected from direct wetting with a minimum of one coat primer and two coats exterior finish paint/sealer. Always check the label of the finishing product and follow the manufacturer’s instructions. During construction, if the wood should become wet, it should be allowed to dry before finishing. Apply finishing product to a small exposed test area of your project before finishing the entire project to ensure 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 the 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 www.epa.gov
  • Use wood preservatives safely. Always read the label and product information before use.
