Untreated wood is vulnerable to moisture as well as insect pests, such as termites. Wooden steps and patios located outdoors can quickly absorb rainwater and snow, causing the wood to warp, erode and eventually rot.
I am trying to make some outdoor 2x4 furniture and I was curious if I needed to use pressure treated lumber if the projects are going to have a finish on them? I don't want them painted, but I saw an arbor/bench at Lowes for $200 that looked like about $20 of pine with a darker stain on it. Let me ...
The guy is a dingbat. Outside you can use standard plywood or waferboard, prime it and paint it or use a waterproofing stain on it. You would want to use treated floor supports if you are burying them into the ground to raise the coop off the ground. If a bug gets in that coop...it will not be there for long.
There are many wood species that can be used for outdoor decks, but not all offer the same benefits and maintenance requirements. Price and availability vary regionally.
I'm new to woodworking and had a question about the best steps I can follow to finish a pine table for outdoor use. I know now after reading different forums that Pine was a very poor wood choice for outdoor use, however, I'm now a little smarter for future projects.
If you want to use real wood for an outdoor project and you expect the wood to withstand termites and fungal decay, your principal choices are either a naturally durable wood (i.e., all-heartwood grade of redwood or all-heartwood grade of cedar) or wood that has been pressure-treated with preservative.
Pressure-treated wood is designed for outdoor applications. It protects wood against wind, sun, debris and moisture. Treated wood lasts a lifetime when properly maintained. But treated wood is also associated with health issues. If you'd rather not deal with it at all, there are options to protect exterior wood.
Wood preservatives are classified as pesticides, so their use is strictly regulated by environmental laws. They should be handled and disposed of with care, following the instructions on the label. A water repellent is a penetrating wood finish loaded with oils or waxes designed to prevent water from soaking into wood.

Natural wood is a lovely choice for adding warmth and texture to garden structures like raised beds, fences, decks and trellises. Much lumber is chemically treated to prevent it from rotting.
Untreated lumber has two advantages -- it’s less expensive than treated lumber and you don’t have to worry about harmful chemicals.- See more home construction pictures.
Untreated pine vs. Treated Lumber for Outdoor Furniture. I have built many adirondack chairs in the past - using both Cypress and treated lumber. Cypress is obviously great for outdoor furniture, however, very expensive. The treated lumber versions have been either stained and/or painted.
