Application Information

Cut ends / Field cuts – When building your outdoor project with pressure treated wood it is important to protect the cut ends, drill holes, and other field cuts.

• For pressure treated timbers and for pressure treated wood used in ground contact applications, a brush on end-cut wood preservative is required at the time of construction on all saw cuts, drill holes and other field cuts. Two applications of a copper naphthenate based end-cut preservative must be applied to the preserved wood before it is installed. Follow the manufacturer’s directions for proper application.
• For pressure treated wood used in above ground applications, such as deck boards, railings, post tops or fencing boards, a brush on end-cut wood preservative or Sealer for Goodfellow Terra^® Pressure Treated Wood should be applied to all saw cuts, drill holes and other field cuts at the time of construction. Follow the manufacturer’s directions for proper application.

Fasteners – Goodfellow Terra treated with MicroPro^® technology exhibits corrosion rates on metal products similar to untreated wood. Use fasteners and hardware that are in compliance with the manufacturer’s recommendations and the building codes for their intended use. Aluminum building products may be placed in direct contact with Goodfellow Terra Pressure Treated Wood products used for interior uses and above ground exterior applications such as decks, fencing and landscaping projects.

Appropriate usage – Above Ground treated wood should not be used in ground contact applications, as this can adversely affect the performance of the entire project. The appropriate usage in noted on the end tag attached to each piece of Goodfellow Terra Pressure Treated Wood.

Pilot holes – Drill pilot holes to minimize splitting especially when nailing or screwing near the edge or end of a board.

Deck board spacing – Because treated wood absorbs moisture during pressure treatment, it is important to butt deck boards together. As the wood dries, some shrinkage can be expected, creating spaces between boards.

Weather-resistant finish – Any exposed wood, pressure treated or not, should be protected with a high-quality water repellent to help reduce warping, checking, and splitting. Follow 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.

Mold growth – 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.
