We take the beauty of Douglas Fir beadboard and custom factory finish them with a rich penetrating stain. This stain color is called Black Walnut and is a great product for a covered porch ceiling. The stain allows the texture of the wood to be seen but changes the color to a rich dark brown. The stain is applied to all six sides creating a uniform finish free from lap marks, runs or streaking and it's a great option versus staining on the job site. This product is recommended for exterior covered porch ceiling or wall applications.
