The video shows a man using a brush to apply a gray substance to a wall. The substance appears to be wet and is being spread evenly across the surface. The man is wearing a white shirt and appears to be focused on the task at hand. The wall is partially covered with the substance, and the man is working methodically to ensure that the entire surface is covered. The brush he is using is wide and appears to be made of stiff bristles, which are ideal for spreading the substance evenly. The substance itself is a uniform gray color and has a thick consistency. The man's movements are deliberate and precise, indicating that he is experienced in this task.
