We take the charm of Cedar tongue and groove siding and then factory machine finish each board in this beautiful Fir/Pine stain. This stain gives the wood a rich golden yellow color and allows the natural wood grain to still show through. When the stain is machine applied to all six sides, it protects the wood against moisture and harmful UV rays. The oil in the stain penetrates the wood and protects more than just the surface of the board making it water repellent with a beautiful rich finish.
