In the video, a person is seen applying a dark stain to a wooden board. The person is wearing a black glove on their left hand and is holding a glass jar of stain in their right hand. They start by applying the stain to the center of the board and then spread it outwards in a circular motion. The person then uses their gloved hand to spread the stain evenly across the board, ensuring that all areas are covered. The stain appears to be a dark brown color, and the wooden board has a light brown hue. The person's movements are steady and precise, indicating that they are experienced in this task.
