Pressure treated wood was first designed back in the ’s. For many decades, it was the only option available for homeowners and builders. In recent years, more options have become available such as composite wood. Pressure treated wood is still a favorite to use due to it’s cost, but there are some scenarios where you should not sure pressure treated wood. We will cover that and much more in the article below. What is Pressure Treated Wood?  Many benefits exist in using pressure treated wood in your next outdoor project. Pressure treated wood does an excellent job of defending against termites, rot and decay which can destroy untreated wood very quickly when exposed to outdoor elements. Another benefit to using pressure treated wood is the cost. Lots of people wonder if you can and should stain pressure-treated wood. The answer is simple: If you want your pressure-treated project to look great, you. Pressure-treated wood is wood that has been infused with chemical preservatives to protect the wood from rot and insects. The wood is placed in a depressurized holding tank that removes the air and replaces it with a preservative. The most important thing to understand about this pressure treatment is that the process is, by far, the best way to avoid harmful rot and insects, but does not prevent weathering and corrosion.  If you’ve already looked into pressure-treated wood for your next project, you may have heard of fasteners and connectors. Fasteners is an umbrella term used for any nail, screw, bolt, or anchor that holds the different pieces of wood together. Connectors is a similar term used for any manufactured device that serves the same purpose.

Pressure-treated wood has been around for nearly 70 yearsyet most of us still know very little about this popular outdoor building material. To start, pressure-treated wood is softwood lumber, typically southern yellow pine, that's been chemically treated to resist rot, decay and termites.

The boards are rolled into giant pressurized tanks where chemical preservatives are forced deep into the wood's fibers. The result is an exterior-grade wood that's ideal for building decks, fences, sheds, picnic tables, swing sets, and other outdoor projects. However, it's important to note that not all treated wood is created equal. The level of rot resistance is directly related to the amount of chemical preservatives in the projects for pressure treated wood, and the type of chemicals used.

Lumber that's stamped "Above Ground Use" should be used only where it won't touch the ground, such as deck railings or fence boards.

Lumber designated for "Ground Contact" can be placed directly on or in the ground. To ensure you're building with the right lumber, check the board's label or stamp for its projects for pressure treated wood retention level.

This number represents the minimum amount of preservative retained in the wood. It's expressed in pounds of preservative per cubic foot of wood.

The higher the number, the more rot-resistant the projects for pressure treated wood is. This confusion began to occur when the industry stopped using chromated copper arsenate CCA for residential use. It's a widely used preservative with a track record of decay resistance going back to when it was introduced in the mids.

CCA retention levels were.

But now retention levels vary depending on the preservative used. For example, a typical wood treatment is micronized copper azole; its retention levels are. The new treatment and retention levels provide the same resistance against decay, weather, and insects. Today, pressure-treated lumber is treated with a range of inorganic chemicals rather than arsenate.

These newer types of treated woods may be less toxic, but they also contain higher levels of copper, so they're much more corrosive than the old CCA-treated lumber. Many pressure-treated lumber manufacturers recommend using only stainless steel or hot-dipped galvanized nails, screws, bolts, anchors, and connectors when working with the material.

And because these new wood treatments are especially corrosive to aluminum, it's best to use vinyl or copper flashing, or to wrap the wood in a protective rubberized membrane. Here are a few extra tips to keep in mind when working with pressure-treated lumber:. Never burn treated wood. Test dryness by sprinkling the wood's surface with water. If the water beads up, the wood is too projects for pressure treated wood and you must wait before applying a finish.

If the water soaks into the wood, then it's dry and ready for stain or paint. This is especially important when fastening near the end of a board. Take this small amount of shrinkage into account when laying decking or fence boards. These hairline cracks are a normal part of the drying process.

Pressure-treated lumber is typically a yellow pine that has been pressure-treated with a preservative. This type of lumber is impregnated with toxins. Generally, this wood should only be used in ground contact and for framing members of an outdoor structure. It should not be used where the lumber can be in permanent contact with animals or humans. Pressure-treated wood contains preservatives to prevent rot and insect damage, but it remains vulnerable to the sun, wind, moisture and dirt. Learning how to stain pressure treated wood can extend the life and improve the appearance of decks, fencing, picnic tables, retaining walls and other exterior wood projects.. Safety: Wear gloves when handling pressure treated wood. If the water soaks in, the wood is dry and porous enough to paint. If the water rests on the surface in beaded drops, the wood must be left to dry longer before painting. Step 3 - Pretreat the Wood with Primer. You need to use primer first before painting, especially because pressure treated wood is so picky about holding onto paint. Make sure.
