How To Paint Shiplap With A Roller: Tips For a Smooth Finish

There’s something undeniably charming about shiplap walls. They bring texture, character, and a touch of timeless appeal to any space. Whether embracing a modern farmhouse aesthetic or creating a stunning accent wall, learning how to paint shiplap properly can make all the difference between an amateur-looking DIY project and one that looks professionally executed.

I recently completed a shiplap painting project in my cottage basement, and I’m excited to share my tried-and-true techniques with you. Let’s dive into everything you need about painting shiplap for stunning results that will last for years.

What Exactly Is Shiplap?

Before we grab our paintbrushes, let’s clarify: shiplap refers to wooden boards with special rabbet joints that allow them to fit together snugly with a small gap. Sometimes it is also a “nickel gap” because a nickel fits perfectly in the space. creating distinctive horizontal or vertical lines. Originally used as exterior siding for weatherproofing, shiplap has made its way indoors as a beloved design element that adds architectural interest to plain walls.

It’s important to distinguish between real shiplap (authentic wood boards) and MDF primed boards that mimic the look. While both can create beautiful results, real wood shiplap often has more character and dimension but may require additional preparation.

Gathering Your Materials

The Right Paint Matters

For my project, I selected paint in eggshell finish, specifically “Sherwin Williams Dew Drop” with “Benjamin Moore White Dove” for the top part, which works wonderfully for shiplap because it:

Provides a subtle, sophisticated sheen
Hides minor wall imperfections better than glossier finishes
Offers good cleanability while highlighting the dimensional aspects
Creates a warm, inviting appearance

When considering the best type of paint for shiplap, quality latex paint is my go-to choice for its durability and easy cleanup. The kind of paint you choose will impact not just the appearance but the longevity of your project.

Designer Tip: Always choose high-quality paint specifically formulated for interior woodwork. The investment pays off in coverage, durability, and overall appearance.

Essential Tools

Here’s what you’ll need for this DIY project:

Small paint brush for shiplap cracks and seams (1-2 inches wide)
Foam paint roller equal to the width of an individual shiplap board
Paint tray with liner
Painter’s tape
Drop cloths
Sandable wood filler or spackle
Fine-grit sandpaper (220 grit)
Paintable caulk for gaps
A page protector or vinyl tab divider (my secret weapon for baseboards!)

Designer Tip: A standard roller will leave stippled marks on the smooth shiplap surface and deposit blobs of paint into the shiplap grooves, which will cause drips. Always use a foam roller for the smoothest finish and great coverage.

Preparation: The Foundation of a Perfect Finish

The secret to professionally painted shiplap lies largely in thorough preparation:

Remove outlet covers: Take off all switch plates and outlet covers for a clean, professional look.
Fill nail holes: Use a sandable wood filler or spackle to patch any nail holes or imperfections.
Sand smooth: Once dry, use a sanding block with fine-grit sandpaper (or a palm sander on real wood shiplap for a perfectly smooth surface).
Address gaps: Apply paintable caulk to any seams or gaps where boards meet trim, corners, or each other.
Clean thoroughly: Wipe down all surfaces with a tack cloth to remove dust and debris.
Protect adjacent areas: Tape off adjoining surfaces and lay drop cloths to prevent accidental splatters.

Designer Tip: Instead of painstakingly taping along the floor, slide a page protector or vinyl tab divider under the edge of the baseboard to protect your flooring while painting. This flexible shield will save you significant time and frustration!

My Proven Painting Technique for Flawless Shiplap

After years of painting various wall treatments, including wood shiplap, ceilings and accent walls, I’ve developed a foolproof method that prevents drips and ensures full coverage. This slow and steady approach consistently delivers the smoothest results.

Step 1: Tackle the Shiplap Cracks First

Working in small sections (about 2 feet at a time), use your small paint brush to paint each groove or seam between boards. This critical step ensures complete coverage of these often-overlooked areas.

Important: Don’t try to paint all shiplap grooves at once! The paint dries quickly, and if you cover too large an area, you risk developing paint lines on the smooth surface that will be difficult to blend later.

Step 2: Roll the Edges

After painting the seams in your 2-foot section, use your foam paint roller to paint horizontal strokes (if your shiplap is vertical) along the top and bottom edges of each board. This technique ensures even coverage where the boards meet trim or other surfaces.

Step 3: Roll Each Board

Finally, roll each board using vertical motions (for vertical shiplap). This consistent directional painting ensures a uniform appearance and minimizes visible roller marks.

Designer Tip: Keep a watchful eye for any drips forming in the shiplap cracks. These can happen quickly and are much easier to fix when wet than after they’ve dried.

Common Challenges and How to Overcome Them

Dealing with Drips

The grooves between shiplap boards are notorious drip collectors. I check my work frequently, especially in the nickel gap seams. If poorly lit use the flashlight on my phone at an angle to catch any potential drips before they dry.

Achieving Even Coverage

Shiplap often has a primer coat from the manufacturer, but don’t let that fool you into thinking you can skip a coat of paint. For the richest, most uniform color and full coverage, plan on applying two coats of your chosen paint.

Brush vs. Roller vs. Sprayer

I’m often asked, “Is it better to paint shiplap with a brush or roller?” The truth is, that a combination approach works best. The small paint brush handles the shiplap cracks precisely, while the foam paint roller provides the smoothest finish on smooth flat surfaces without the texture that standard rollers leave behind.

While I love spraying shiplap for efficiency, I’ve found that the prep work often outweighs the benefits for smaller projects. Use a paint sprayer when:

It’s new construction without flooring installed
You’re using just one color throughout the space
You have large, open areas of shiplap or a shiplap ceiling

For most residential touch-ups or single accent wall projects, the brush and roller method I’ve described yields excellent results with less setup and cleanup.

Before or After Installation?

A common question for DIY project enthusiasts is whether to paint shiplap before or after installation. Here’s my take:

Pre-installation painting advantages:

Easier to access all surfaces
No worries about getting paint on adjacent surfaces
This can be done in a controlled environment according to your plans

Post-installation painting advantages:

Nail holes and seams can be properly filled and finished
No touch-ups are needed for installation marks
Ensures a uniform appearance across all boards

I’ve tried painting the seams before installation, which can work well with MDF primed boards, but you must use extreme caution to avoid getting paint on the front of the boards. Any dried paint marks will require sanding with a palm sander later, which ultimately doesn’t save time. In my experience, the post-installation method I’ve described produces the most professional results.

Choosing the Right Paint Finish for Shiplap

“Should shiplap be painted flat or gloss?” and “What sheen of paint do you use on shiplap?” are questions I hear often. After experimenting with various paint finishes, I’ve found that eggshell offers the perfect balance for most shiplap installations. Here’s why:

Flat/Matte: While it hides imperfections beautifully, it’s harder to clean and may look too dull, missing the opportunity to highlight shiplap’s dimensional character.
Eggshell: Provides a subtle lustre that enhances the textural elements while remaining sophisticated and versatile for any room.
Satin: A good middle-ground option with slightly more sheen than eggshell, excellent for kitchens and bathrooms.
Semi-gloss: Highly durable and cleanable but can highlight any imperfections in your installation.
High-gloss: Generally too reflective for shiplap, creating too much visual distraction.

For most of my shiplap installations, including accent walls and ceilings, paint in eggshell finish has proven to be the perfect balance of subtle sheen, durability, and a refined appearance.
