Whether your customer is building a new planter or replacing their deck, Georgia-Pacific pressure treated lumber products are a high-performance decking choice. Here are some helpful tips to assist you with your treated lumber project.
FASTENER RECOMMENDATION - Use only hot-dipped galvanized or stainless steel fasteners, connectors and hardware to help safeguard the structural integrity of projects built with ACQ-D or CA-C treated wood. As a minimum requirement for use with ACQ-D or CA-C treated wood, hot-dipped galvanized coated fasteners should conform to ASTM Standard A 153 and hot-dipped galvanized coated connectors should conform to ASTM Standard A 653 (Class G-185). In demanding applications, such as treated wood foundations and playground equipment, use of stainless steel fasteners and connectors should be utilized and may be required by building codes. Electroplated galvanized fasteners are not recognized as being corrosion resistant for exterior applications. Aluminum should not be used in direct contact with ACQ-D or CA-C treated wood.
NAIL BARK SIDE UP - Always nail boards bark side up (annual rings arc upward) to reduce
cupping. Nail thin boards to thicker boards to help maintain structural integrity.

DRILL PILOT HOLES - Especially when nailing near the edge or end of a board, it is a good idea to drill pilot holes for your fasteners.
BUTT BOARDS TIGHTLY - Butt decking boards together firmly. As drying occurs, shrinkage can be expected.
APPLY A WEATHER-RESISTANT FINISH - Any exposed wood, pressure treated or not, should be protected from the weather. Application of a finish coat of clear or semitransparent water-repellent stain will help to minimize warping, checking or splitting. Follow finish coat manufacturer's recommendations for application instructions and how often to apply.
PAINTS AND STAINS - Pressure-treated wood may be painted or stained to match any outdoor color scheme. High-quality latex-based paints and oil or latex stains are recommended. Make sure the wood is dry and free from surface deposits before applying any coating. Follow finish coat manufacturer's recommendations for application instructions and how often to apply.
