Yes, that's what it was intended for. As long as it has not been previously sealed or painted and is porous, clean and dry. YOu can test the porosity by spritzing some water droplets on the surface to see if they penetrate and turn the surface darker. If so, you are good go. Otherwise, if the droplets sit on the surface for 5 minutes, then the surface may have been sealed or is too dense for this product to penetrate. TEST first.
