Step-by-Step Guide on How to Paint Trim

Knowing how to paint trim like a professional can drastically improve the overall appearance of a room. Follow this step-by-step guide to achieve the perfect finish.

1. Prepare Your Work Area

Proper preparation is key to a successful paint job. Start by laying down drop cloths or plastic sheeting to protect your floors from spills and drips. If you’re painting baseboards, make sure to tape masking paper along the floor edge to catch any stray paint. Taking this extra step will save you a lot of time on cleanup later.

2. Fill in Holes and Imperfections

Trim can get scratched or dented over time. Use a putty knife to apply wood filler to any nail holes or cracks in the trim. Let the filler dry completely, then sand the area smooth. This ensures a clean, even surface for the trim paint to go on.

3. Sand the Trim for a Smooth Finish

Use a fine-grit sanding sponge to lightly sand the trim. Sanding removes any gloss or imperfections, making it easier for the paint to adhere properly. If you’re working with freshly installed trim, sanding may not be necessary. However, sanding older trim is a must for a clean, smooth surface.

4. Clean the Trim Thoroughly

Before you start painting, wipe down your trim with a microfiber cloth to remove any dust or debris. For greasy trim, clean it with a mixture of warm water and trisodium phosphate (TSP) to remove dirt. A clean surface is vital for getting a smooth, flawless finish when applying trim paint.

5. Caulk the Edges for a Seamless Look

Using a caulking gun, apply a thin line of caulk where the trim meets the wall or ceiling. Caulking helps create a seamless transition and fills in small gaps, giving your trim a polished, professional look.

6. Tape Off the Trim for Clean Lines

Apply painter’s tape carefully along both sides of the trim. Make sure the edge of the tape aligns just next to the trim without touching it. Proper taping is key to getting those sharp, crisp lines around your trim.

7. Prime the Trim if Necessary

If you’re working with raw wood trim or making a drastic color change, priming is essential. A coat of primer helps the trim paint adhere better and prevents any stains or previous colors from bleeding through. Let the primer dry before moving on to the paint.

8. Apply the First Coat of Paint

Now it’s time to start painting! Use your 2-inch angled paintbrush to apply the first coat of paint. Be sure to load the brush lightly to avoid drips, and paint along the trim in long, smooth strokes, following the natural wood grain. Thin coats work best, so don’t overload the brush.

9. Apply a Second Coat for a Professional Finish

Once the first coat has dried completely (about 4 hours), apply the second coat. This second coat provides an even, rich finish and helps ensure the trim looks flawless. Take your time to ensure smooth, even coverage.

10. Remove the Painter’s Tape

After the second coat has dried (about 4 hours), carefully peel off the painter’s tape. To avoid smearing the paint, pull the tape back at a 90-degree angle. This will leave you with sharp, clean lines around the trim.

Pro Tips for a Perfect Trim Painting Project

  • Use a quality angled brush for precise control when painting trim.

  • Don’t overfill the brush. A brush with too much paint can cause drips and uneven coverage.

  • Be patient between coats—let the paint dry thoroughly for a smooth, streak-free finish.
  • Smooth out caulk to ensure a clean finish between trim and walls.
  • Allow adequate drying time between coats to avoid smudging and uneven results.
