Use any acrylic latex paint recommended for outdoor use on pressure treated wood. Paint brands specifically for use on pressure-treated wood do not exist. The key to painting pressure-treated wood is preparing it. Clean the wood, and let it dry completely before painting.Continue Reading
Pressure-treated wood is resistant to absorbing water and other liquids such as paint or stain. To remove the outer layer of the water-resistant chemicals, wash the pressure-treated wood thoroughly with soap and water. Use gloves when handling the wood because the chemicals are harmful to the skin or if accidentally ingested.
Wait days or even weeks after washing the wood for it to completely dry. Test the dryness by sprinkling some water on the wood. If the water beads up on the wood, let the wood dry for longer. If the wood absorbs the water, it is time to paint. Painting pressure-treated wood without washing it or before it is completely dry results in the paint not sticking to the wood.
Follow the manufacturer's directions for the paint. Use an alkyd oil-based primer before painting to help the paint last longer. Use acrylic latex top coat paint for the longest lasting results. Detail work may require a brush, but for general application, use a spraying system.Learn more about Home Maintenance
