How to Paint Trim and Baseboards Like a Pro

How to Paint Trim and Baseboards Like a Pro

Rodrigo Pereira Teixeira |

Painting trim and baseboards may seem like a small detail, but it’s one of the most important steps in making your space look polished and professional. Clean, crisp trim adds contrast, frames your walls, and elevates the entire room. Here are the most common questions homeowners ask about painting trim and baseboards.


1. Why is painting trim and baseboards important?

Trim and baseboards frame your walls, protect edges from scuffs, and give your home a finished look. Freshly painted trim instantly makes any room look cleaner and more updated.


2. What type of paint works best for trim and baseboards?

  • Semi-gloss or gloss finishes are most popular—they’re durable, easy to wipe clean, and highlight architectural details.

  • Water-based (latex) paint is quick-drying and low odor.

  • Oil-based paint provides a smoother, harder finish but takes longer to dry.

3. Do I need to use primer on trim?

Yes, especially if:

  • The trim is bare wood.

  • You’re painting over dark or stained wood.

  • The surface is glossy (in which case a bonding primer helps).

4. How do I prepare trim and baseboards for painting?

  1. Clean with soap and water to remove dust and grime.

  2. Sand lightly to smooth the surface and improve adhesion.

  3. Fill gaps or nail holes with caulk or wood filler.

  4. Tape off walls and floors with painter’s tape.

5. Should I paint trim before or after walls?

Most professionals recommend painting trim first, then walls. It’s easier to cut in on the walls later than to tape trim perfectly.


6. What tools should I use for painting trim?

  • Angled sash brush (2-inch): Perfect for clean lines and corners.

  • Painter’s tape: Protects walls and floors.

  • Drop cloths: Keep floors free from drips.

7. How do I avoid brush marks on trim?

  • Use high-quality angled brushes.

  • Don’t overload with paint.

  • Apply in long, smooth strokes, following the wood grain.

  • Lightly sand between coats if needed.

8. How many coats of paint should I apply?

Two coats are usually best for durability and consistent colour. Allow the first coat to dry completely before adding the second.


9. Should I hire a professional for trim painting?

Yes, especially if your trim has intricate details, or if you want perfect, sharp lines. Use our Painter Order Formto connect with trusted painters.
