Dry First Coat and Lightly Sand

What happens here

Let the first coat dry for at least two hours. Once dry, inspect the surface for any small 'peaks' or high spots that might catch the trowel during subsequent coats. Lightly sand these imperfections using your hand or a sanding block to knock them off, ensuring a smoother base for the next layers. The presenter states the product instructions call for 600-grit sandpaper in a circular motion, but for this step, just knocking off high spots is sufficient.

Goal: Allow the first coat to dry, then lightly sand any imperfections.
