Prime and Sand Grain-Filled Face Frames

What happens here

With the cabinet doors complete, turn attention to the cabinet face frames. After any necessary grain filler application and drying (similar to the doors), apply a first coat of primer sealer to all face frames using a spray gun. Ensure proper ventilation during this process. Allow the primer to dry completely. Once dry, use a sanding sponge with fine grit (e.g., 220-grit) to lightly sand the face frames. This step smooths out any minor imperfections, removes any remaining grain texture, and prepares the surface for the topcoat. Ensure all sanding dust is thoroughly removed with a tack cloth before proceeding.

Goal: Apply a first coat of primer sealer to the cabinet face frames (after implied grain filler application), allowing it to dry, and then sand the frames to achieve a smooth finish.
