Pressure-treated wood is a type of wood that has been treated with chemicals to protect it from rot, decay, and insects. It is often used for outdoor projects, such as decks, fences, and siding. There are a few different ways to tell if wood is pressure treated.
One way to tell if wood is pressure treated is to look for a stamp or label on the wood. This stamp or label will usually indicate that the wood has been pressure treated and will also specify the type of treatment that has been used. Another way to tell if wood is pressure treated is to look at the color of the wood. Pressure-treated wood is typically a greenish color, although the color may vary depending on the type of treatment that has been used.
