Where to Use Pressure-Treated Wood. While many homeowners wonder if they should use pressure-treated wood for a specific project, the answer is simple. Wood for any outdoor project should be pressure-treated; wood for indoor projects should be left as is. The sawdust from pressure-treated wood is an irritant to the eyes, skin, and nose. Some low level leaching (the chemical preservative leaking from the wood) can also be a problem with indoor projects.

Producers generally add a color agent or a trace amount of copper solution so as to identify the wood as pressure treated and to better match the color of other pressure treated wood products. The PTI wood products are very well adapted for paint and stain applications with no bleed-through.
