Solid wood siding includes shakes, shingles, and planks that are manufactured from a number of different wood species including cedar, redwood, oak, and pine. While it can be installed unfinished manufacturers typically recommend coating the siding to protect the wood from moisture, UV degradation, and mildew. A wide variety of film-forming and penetrating finishes are available. These include water repellents, clear water repellent preservatives, bleaching oils and bleaching stains, semi-transparent and opaque stains, paints and primers. A variety of finish chemistries are available including water-based acrylics and alkyds, solvent-based alkyds, oil-based alkyds, tung oil, linseed oil, and siloxanes.
Finishes can be factory- or site-applied. Depending on the desired aesthetic different finishes may be recommended. For instance, clear-water repellents and bleaching oils and stains are used to achieve a weathered look, while stains and paints offer more UV protection.
Some wood siding may be pressure treated to protect it from decay. While most pressure-treated wood for residential use has transitioned away from chromated copper arsenate (CCA), some products used for siding applications can still contain it. While not found to be common, it is still used in some shakes and shingles that may be used for siding.
The common contents for this CP include the wood itself and a penetrating semi-transparent stain that has been factory-applied. Additional information on a range of finish and treatment options identified in our research are included in the All Contents.
