Interior Wood Surfaces
Interior wood surfaces to receive stain shall be sanded. Oak and other
open-grain wood to receive stain shall be given a coat of wood filler
recommended by the finish manufacturer not less than 8 hours before the

wood shall be patched with approved patching compounds, and shall be sanded
smooth. The source or cause of wood decay shall be identified and
corrected prior to application of patching materials. Wet wood shall be
completely dried to a moisture content not exceeding 12 percent, as

where portions of wood are missing such as holes, cracks, gaps, gouges, and
other voids.
