You just had new trim installed and while the crisp lines look great, every nail gun hole is staring back at you like tiny polka dots across the surface. Or maybe you’re working with older trim where nail holes from past projects were never filled correctly and now stand out even more after painting. Whether it’s brand-new woodwork or trim that’s been in place for decades, nail holes can distract from what should be a smooth, finished surface.
At Brush & Roll Painting in Omaha, we’ve been working with homeowners ready to transform their homes since 1996. We understand the difference between trim that looks patched together and trim that looks polished and seamless. Filling nail holes in trim is something professional painters handle daily, but it’s also one of those details that separates a quick paint job from a high-quality one.
In this article, you’ll learn the best ways to fill nail holes in painted trim, the difference between caulk and wood filler, and why the right product matters. You’ll walk away with a clear understanding of how professionals approach this step and what to expect if you’re hiring a painter for your project.
Trim, whether it’s baseboards, door casings, or crown molding, is designed to frame the space. Because it’s often painted in white or light shades, imperfections are easier to spot than on darker walls. A line of nail holes left unfilled can catch the light differently, leaving small shadows that break up the smooth surface.
Even after the trim has been painted, nail holes can expand or contract with changes in temperature and humidity, making them more visible over time. Omaha homeowners know how much our seasons shift, and this can be especially noticeable in older homes with real wood trim.
If you’ve searched “how to fill nail holes in white painted trim” or “fill nail holes in trim before painting,” you’re not alone. It’s one of the most common homeowner questions. Here’s how professionals typically approach the process.
A big question homeowners ask is whether caulk or wood filler is better. Both are used in painting projects, but they serve different purposes.
Caulk is flexible and great for filling gaps where trim meets walls or where corners connect. It moves with the house as it expands and contracts. But when it comes to nail holes, caulk often falls short. Because it’s soft and shrinks over time, the filled hole may sink in or even pop back open.
Homeowners sometimes use caulk for nail holes because it’s easy to squeeze into place, but on painted trim, it can leave little dips or shiny spots that are just as noticeable as the original hole.
Wood filler (also called putty or spackle, depending on the product) is designed to harden. It doesn’t flex like caulk, which makes it ideal for nail holes. A painter presses it into the hole, sands it smooth, and paints over it. The finish looks solid and seamless.
The downside is that wood filler takes more time. It has to dry fully, and sanding adds another step. But if you want nail holes to disappear, this is the professional approach.
If nail holes are just painted over or filled with the wrong product, you’ll likely notice one of three issues:
In Omaha’s climate, with dry winters and humid summers, the wrong approach can mean repainting or touching up trim sooner than you’d like.
Here are some common searches and the answers:
How to fill nail holes in trim without painting?
It’s possible to use a color-matched putty stick on small holes, especially on wood trim, but on painted trim, the repair will almost always need touch-up paint to blend.
Best nail hole filler for painted trim?
Painters often use lightweight spackle or a high-quality wood filler. The key is choosing one that sands easily and doesn’t shrink.
Best way to fill nail holes in trim before painting?
If the trim hasn’t been painted yet, fillers are easier to use because the whole surface will be painted after sanding. This gives a flawless look.
Filling nail holes in trim after painting
This is trickier, since the filled area will need touch-up paint. Professionals usually feather out the paint so the repair disappears.
