After all molding pieces are installed, the final step involves preparing them for a seamless finish. Fill all nail holes with wood putty and caulk any gaps between the molding pieces and the wall, as well as any joints where pieces meet. Once the putty and caulk are dry, sand smooth any rough areas. Finally, paint the entire combined molding structure with your desired trim paint. When properly caulked and painted, the individual pieces will blend together, creating the illusion of one solid, custom-milled piece of trim. This method offers a cost-effective way to achieve a high-end, bespoke look.
