Apply and Sand Second Skim Coat

What happens here

Apply a second coat of the mixed gypsum powder to the wall using the same technique as the first coat: roll it on, then smooth with a trowel or squeegee. This layer is often crucial for completely obscuring any remaining texture and achieving a truly smooth finish. After the second coat has dried, perform a final light sanding to achieve a 'level five' finish. This involves meticulous sanding to eliminate any minor imperfections, leaving the wall uniformly smooth and ready for paint, wallpaper, or specialized decorative finishes.
