A person is seen smoothing out a thin layer of wet, grey cement or mortar on a surface that appears to be a floor or a large panel. They are using a rectangular trowel with a red handle, moving it in a smooth, back-and-forth motion. The person is wearing bracelets on their left wrist. The lighting in the video is not very bright, and the floor or panel appears to have some pre-existing discoloration and minor surface irregularities.
