With the trim primed and imperfections filled, it's time for the first coat of paint. Use a good quality 3-inch angled brush and apply the chosen paint color, in this case, 'Extra White' semi-gloss finish. Maintain long, even strokes, working from top to bottom. The video shows both the man and woman applying the paint, cutting in carefully around door and window frames, and along the baseboards.
Goal: Apply the initial layer of final paint color
This project provides detailed instructions on how to properly prepare and paint old wood trim that has existing varnish. It covers removing doors, protecting floors, sanding to create adhesion, thorough cleaning, applying a bonding primer, filling imperfections with wood filler, and finally applying the topcoat of paint. The process ensures a durable and aesthetically pleasing finish.
Apply a coat of high-quality primer to all new trim and skirt boards. Allow the primer to dry completely. Lightly sand any areas that feel rough after priming. Apply your chosen paint color in thin, even coats. Allow each coat to dry thoroughly before applying the next. Typically, two coats of paint are sufficient for good coverage.
This project involves removing old stair skirt boards and trim, preparing the wall and stairs, and installing new skirt boards and trim for a refreshed look. It includes measuring, cutting, fitting, fastening, and finishing the new trim pieces.
