I have painted many stair skirt boards black and even the handrail. In many instances people see it and love it. I use Benjamin Moore Oil based paint in black. I love this look with almost any handrail application even in a more traditional home that has white spindles. The painted skirt boards are not only beautiful but hide a multitude of scuff marks and dirt which is great if you have kids or pets. I can even see this with a painted color such as Benjamin Moore Rustic Taupe. Happy Wednesday.
