Final Inspection and Topcoat Preparation

What happens here

After the primer coat has thoroughly dried, conduct a final inspection of all primed trim surfaces. The primer will often highlight any missed imperfections, pinholes, or areas that require additional sanding or bondo/spackle. Address any newly visible imperfections by touching up with appropriate filler. Once any touch-ups are dry, perform a light final sanding to ensure ultimate smoothness. After sanding, vacuum and thoroughly dust all surfaces to remove any sanding residue, as dust can compromise the adhesion and finish of the topcoat. With the trim now perfectly smooth and clean, it is ready for two coats of the desired topcoat paint.

Goal: Perform a final, thorough inspection after the primer dries to identify any remaining imperfections, then touch up as needed, sand one last time, and dust before applying the final topcoats of paint.
