What happens here

Once the first coat of skim coat has fully dried, it's time to sand it smooth. Use the Festool Planex sander, now fitted with 180-grit sandpaper, for this step. The goal is to lightly sand the entire surface, removing any ridges, bumps, or trowel marks left from the first application. This process creates a smoother and more uniform base, preparing the wall for the subsequent coats and ensuring a flawless final finish.
