How to Paint Trim & Baseboards

Get crisp, smooth trim lines.

Crisp trim makes a whole room look finished. Trim takes more wear than walls and shows brush marks more, so prep and a quality paint matter.

Prep and fill

Clean the trim, fill nail holes and gaps with filler and caulk, and lightly sand glossy old trim so new paint grips. Wipe off dust. Smooth trim starts with smooth prep.

Tape if needed

Tape along the wall and floor edges if your hand isn't steady, pressing the tape down firmly so paint doesn't bleed under it. Many pros cut in freehand with a good angled brush instead.

Use the right paint and technique

Use a durable trim enamel and a quality angled brush. Lay the paint on and tip it off with light strokes in one direction for a smooth finish. Two thin coats beat one thick one, which sags and shows marks. Pull tape while the last coat is slightly wet.

Frequently asked questions

What kind of paint should I use on trim?

Use a durable trim or door-and-trim enamel, which is harder-wearing and levels smoother than wall paint. Two thin coats give the best finish.

Should I paint trim or walls first?

Many painters do trim first, then walls, cutting the wall paint to the trim. Others do walls first. Either works — just let each fully dry before taping over it.
