Trim Painting Tips to Instantly Brighten Your Home

When you think of refreshing your home, it’s easy to jump straight to wall colors or furniture upgrades—but here’s a little design secret: your trim is doing more work than you realize. Those baseboards, crown moldings, window casings, and door frames act as elegant frames to the rooms you spend the most time in. And when they’re dingy, scuffed, or dull? Even the most beautiful wall color can lose its luster.

The good news? A simple trim painting project—when done right—can instantly brighten and elevate your space, making your home feel cleaner, fresher, and more polished. Whether you're prepping for resale or just craving a little change, here's everything you need to know from the pros at Pro Painting & More.

Choose the Right Paint Type & Sheen

Not all paints are created equal—especially when it comes to trim. While you might use eggshell or matte on your walls for a soft finish, trim calls for something more durable and light-reflective.

We recommend a semi-gloss or satin finish for trim work. These sheens are tough enough to withstand bumps and fingerprints (especially in high-traffic areas), and they reflect just enough light to give your trim a crisp, clean look that naturally brightens a room. White is always a classic choice—it pops against colored walls—but don’t be afraid to explore rich creams, soft grays, or even dramatic dark tones if you’re going for contrast.

Prep Is Everything

Here’s where DIY trim painting projects can go sideways: skipping the prep work. Professional-looking results start with a smooth, clean surface.

• Clean Thoroughly – Dust, dirt, and grime love to settle on trim. Use a damp cloth with mild soap to wipe everything down.

• Sand the Surface – A light sanding helps remove imperfections and gives the new paint something to grip. Focus on smoothing out previous brush strokes or chipping.

• Fill Gaps & Holes – Use spackle for small nail holes and caulk for seams where trim meets the wall. This creates those clean, seamless edges you see in magazines.

• Protect Adjacent Surfaces – Tape off walls, floors, and any areas you don’t want paint on. A good drop cloth is your best friend here.

We like to say: the time you spend prepping can save you double the time (and frustration) later on.

Use the Right Tools for a Smooth Finish

Professional results come from professional tools—even if you're painting it yourself. The ideal brush for trim is a high-quality angled sash brush (around 2 to 2.5 inches). That angled tip gives you more control, especially in corners and around edges.

If you’re painting long, flat surfaces like baseboards, a trim-sized foam roller can help you lay down smooth, even coats quickly. Just remember to follow up with a brush to “tip off” the paint and avoid roller texture.

Should You Prime First?

If your trim is currently stained wood or an old, glossy finish, you’ll need a good bonding primer to help your new paint adhere properly and prevent bleed-through. If it’s already been painted and is in good condition, you may be able to skip this step—especially if you’re using a paint that includes primer.

Paint in the Right Order

One of the biggest time-saving tricks? Paint your trim before you paint your walls. We know—it might sound backwards—but this method actually makes things cleaner and faster.

Here’s why: trim painting often involves more careful brushwork and a bit of tape. Once it’s dry, it’s easier to tape it off and roll your walls without worrying about smudging or overpainting. Start from the top (crown molding) and work your way down (baseboards). Trust us—it’s a game-changer.

Go Slow, Use Even Strokes, and Sand Between Coats

It’s tempting to try and knock out your trim in one thick coat, but resist the urge! The key to a professional finish is applying thin, even layers, letting them dry fully, and lightly sanding between coats for the smoothest surface possible. This extra step is what gives trim that flawless, factory-finished look.

Why Trim Painting Is Worth the Effort

Trim painting may seem like a small project, but it has a big visual payoff.

✔️ Brightens every room – A fresh white or light-colored trim bounces light around and makes the space feel airier. 

✔️ Adds polish – It’s those small details that take a home from “fine” to “wow.” 

✔️ Improves cleanliness – Scuffed, stained trim can make even clean rooms feel dingy. Fresh paint instantly refreshes your space. 

✔️ Budget-friendly impact – Compared to a full interior repaint, updating your trim is a lower-cost way to modernize your home.

Whether you're preparing your home to sell or just updating your space to better reflect your style, trim painting is one of the simplest, most cost-effective upgrades you can make.
