In the video, a person is seen using a tool to apply a white substance to a wall. The tool appears to be a long, thin rod that is being pushed against the wall, leaving a trail of the white substance behind. The wall itself is a light color, possibly white or beige, and there is a wooden frame visible on the left side of the frame. The substance being applied is thick and appears to be some kind of plaster or putty. The person is moving the tool in a steady, back-and-forth motion, ensuring that the substance is evenly distributed across the wall.
