In the video, a person is using a spray gun to apply a dark stain to a wooden board. The board is placed on a concrete surface, and the person is moving the spray gun back and forth to ensure even coverage. The stain appears to be a deep brown color, and the person is wearing a black glove on their hand. The spray gun is connected to a canister, which is presumably filled with the stain. The person is methodically covering the entire surface of the board, ensuring that no spot is left untouched. The video is shot in a close-up angle, focusing on the board and the spray gun.
