What happens here

Allow the first skim coat to dry completely, which typically takes around 2 hours, potentially faster with a fan. Once dry, lightly sand the entire wall surface using the Festool Planex sander with 180-grit sandpaper. This step removes any remaining texture, roller marks, or small imperfections from the first coat, ensuring a smoother base for the next application. Continue using the vacuum system to manage dust.

Goal: After the first coat is dry, lightly sand the entire surface with a 180-grit sandpaper on the orbital sander to remove imperfections and prepare for the second coat.
