We take the beauty of Douglas Fir beadboard and custom factory finish them with a rich penetrating stain. This stain color is called Dark Slate and is a great product for a covered porch ceiling. The stain allows the texture of the wood to be seen but changes the tone to a rich dark gray almost black. 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.
