The video shows a close-up of a wall with a rough texture. The wall is gray in color and appears to be made of concrete or stone. A person's hand is seen holding a white brush and applying a gray substance to the wall. The substance is being spread evenly across the surface of the wall, covering the rough texture and creating a smoother finish. The person's hand moves back and forth as they apply the substance, ensuring that the entire surface is covered. The video does not show the entire wall, but rather focuses on a small section of it.
