Non-porous woods do not have as many vessels within the wood fibers. The cells are typically smaller, and the grain of the wood is wide and open. Non-porous woods are typically softwoods, including those from conifer trees. They vary in color and can have a beautiful unfinished appearance. Non-porous softwoods do not readily accept stain, but their weak nature requires them to be coated with paint or clear polyurethane. They are otherwise susceptible to cracking and splitting. Non-porous woods are prepared in much the same manner as porous woods, so they are cut and sanded using the same techniques. Most furniture makers and cabinetmakers avoid using non-porous woods for large projects. However, cedar and pine are frequently used for tables and floors.
