In the video, a person is seen applying a coat of varnish to a wooden board. The person first pours the varnish onto the board and then uses a brush to spread it evenly across the surface. The brush is moved back and forth in a smooth motion to ensure that the varnish is applied evenly. The person's movements are deliberate and careful, ensuring that the varnish is applied without any streaks or spots. The wooden board appears to be of a medium brown color, and the varnish is a clear, glossy liquid. The person is wearing a gray t-shirt and khaki shorts, and the background is a garage with a blue tarp on the floor.
