How to Repair Scuffs and Scratches on White Trim

Trimwork serves as the frame for your home, and when it's covered in black scuffs and unsightly dings, the entire room feels neglected. White trim is notoriously unforgiving, but because it is usually painted with a durable, high-gloss or semi-gloss enamel, it is also one of the easiest surfaces to restore to a factory-fresh finish without having to repaint the entire length of the baseboard. The secret to an invisible repair is managing the texture of the patch. If you simply glob paint over a gouge, you end up with a high-profile lump that catches the light and draws the eye. Success here is all about feathering your sandpaper and thinning your paint just enough to let it settle into the grain, leaving you with a seamless transition between the new paint and the old finish.

Remove All Surface Grime. Wipe the scuff mark with a cloth dampened with a mild degreaser or dish soap and water. Ensure all dust, oils, and floor debris are completely removed so the new paint can bond properly.
Smooth the Rough Edges. Use 220-grit sandpaper to smooth out any raised edges or burrs around the scratch. Only sand the damaged area and extend no more than an inch beyond the imperfection to preserve the surrounding finish.
Fill Chips and Dents. If the scuff is a physical dent or chip, apply a thin layer of spackle using a small putty knife. Once dry, sand the filler until it is perfectly flush with the surrounding trim.
Seal Before Color. Dab a small amount of primer over the spackled area or raw wood. This prevents the paint from soaking into the filler and appearing dull compared to the rest of the trim.
Stipple, Don't Brush. Use a small, high-quality artist's brush to dab the paint onto the spot. Do not brush it back and forth; instead, stipple the paint on and let it self-level naturally.
Blend Into Existing Finish. Use your fingertip or a dry brush to gently soften the edges of the wet paint. This blends the new application into the existing finish so there is no hard line.
