Painting Doors and Trim

A hybrid alkyd or acrylic enamel paint in semi-gloss or satin finish provides the most durable and smooth result on interior doors and trim. Products like Benjamin Moore Advance and Sherwin-Williams ProClassic level out well and resist fingerprints, scuffs, and yellowing over time. These paints perform best when applied over a properly sanded and primed surface.

Professional painting of an interior door typically costs between $75 and $200 per door, depending on whether it is a flat slab, panel door, or French door with glass panes. Doors with detailed millwork or louvers require more labor and fall at the higher end of the range. Many homeowners bundle door painting with a full interior project to reduce per-unit cost.

The keys to brush-mark-free trim are using a high-quality enamel paint with good leveling properties, a fine-bristle angled brush or small foam roller, and applying thin, even coats rather than heavy layers. Lightly sanding between coats with 220-grit sandpaper also helps create a smooth surface. Professional painters often spray trim and doors for a factory-smooth finish that brushwork alone cannot match.

Semi-gloss has traditionally been the standard for trim because of its durability and easy-to-clean surface, but satin finishes have gained popularity for their softer look while still being wipeable. Semi-gloss is the better choice for high-traffic areas, kitchens, and bathrooms where moisture resistance matters most. Satin works well for bedrooms, living rooms, and homes with a more modern aesthetic.

A front door can be painted while still on its hinges, but removing it and laying it flat produces a smoother, drip-free finish, especially when using spray equipment. If the door stays in place, careful masking and working in thin horizontal passes minimizes runs. Hedlund Painting removes front doors when possible to ensure the most even coat and proper coverage of all edges.

Most water-based enamel paints are dry to the touch within two to four hours but take 14 to 30 days to fully cure and reach maximum hardness. During the curing period, avoid slamming doors or placing heavy objects against painted trim to prevent dents and marks. Keeping rooms well-ventilated speeds up the curing process.

Painting baseboards and trim at the same time as the walls creates a much cleaner, more finished look and costs relatively little extra when the crew is already set up. Scuffed, yellowed, or mismatched trim next to freshly painted walls makes the entire room look incomplete. Including trim in your project scope delivers the biggest visual impact per dollar spent.

Proper preparation includes cleaning all surfaces to remove grease and dust, lightly sanding with 150 to 220-grit sandpaper to create a tooth for the new paint, filling any dents or nail holes with wood filler, and applying a coat of primer to bare or repaired spots. Skipping the sanding step is the most common cause of peeling paint on trim. Hedlund Painting follows a detailed prep checklist on every door and trim project in the Seattle metro area.
