Pressure treated wood is fantastic for outdoor use. As the name suggests, it’s been treated with chemicals and sealants that protect it from outdoor elements such as rain, wind, bugs, snow, and mildew. However, if you're not into the natural look and want to paint the wood, you're going to have some extra work to do. While it doesn’t require a lot of additional work, it does require waiting a large amount of time for the wood to be clean and dry enough to paint. Pressure treated wood is completely paintable, but it must be done properly, otherwise the paint won’t last very long.
