Exterior shiplap siding is a popular design choice for homes due to its versatility, durability, and aesthetic appeal. It is typically made from wood, such as cedar or pine, or composite materials that mimic the look of wood. Before painting exterior shiplap siding, it is essential to prepare the surface properly to ensure a smooth and long-lasting finish. One crucial step in this process is sealing any seams or gaps between the boards to create a seamless look. This can be achieved by using caulk, a flexible sealing compound, to fill in any seams, gaps, or edges before applying paint. This guide will explore the benefits of glazing exterior shiplap siding seams and provide step-by-step instructions on how to achieve the best results when painting exterior shiplap siding.

What You'll Learn

Filling gaps and seams with caulk
Choose the Right Caulk
Select a suitable caulk for your project. Acrylic caulk, also known as latex caulk, is a popular choice for shiplap as it is water-soluble and easy to work with.
Prepare the Shiplap
Before caulking, ensure your shiplap is installed correctly and securely. Work on one section at a time to make the process more manageable.
Apply the Caulk
Run a bead of caulk along the seams and edges of the shiplap, focusing on areas where the shiplap meets a wall, inside corner, or moulding. Use a consistent amount of caulk to ensure an even finish.
Smooth and Wipe Excess
Use a clean finger or rag to smooth out the caulk, ensuring it fits neatly into the seams. Wipe away any excess caulk immediately with a lint-free rag dampened with soapy water. This step is crucial to prevent the caulk from drying and affecting your paint job.
Allow to Dry
Give the caulk sufficient time to dry completely before proceeding with painting. Refer to the manufacturer's instructions for the recommended drying time.
Paint the Shiplap
Once the caulk is dry, you can begin painting your shiplap. For best results, use a paint sprayer or a brush and roller, depending on the size of your project and your personal preference.
Remember, caulking is an excellent way to fill gaps and seams, cover installation mistakes, and ensure a seamless, professional finish for your shiplap siding.

Using acrylic caulk for a seamless look
Exterior shiplap siding is a versatile design option that can be customised to match your desired colour scheme. However, it requires regular maintenance, such as painting or staining, to protect the wood from the elements and prolong its lifespan. Before painting, it is essential to fill in any gaps and seams to create a seamless and professional look.
Acrylic caulk, also known as latex caulk, is ideal for creating a seamless finish on your shiplap siding. It is easy to use and can be painted over to match the surrounding decor. Here is a step-by-step guide to using acrylic caulk for a seamless look on your exterior shiplap siding:
- Prepare the Area: Ensure the surface is clean, dry, and free of debris. If there is any old caulk present, use a utility knife or a painter's tool to remove it carefully.
- Apply Painter's Tape: Painter's tape is optional but highly recommended, especially for beginners. It helps create clean, crisp lines and prevents caulk from straying beyond the desired area. Apply the tape along the seams or edges where you will be applying the caulk.
- Cut the Caulk Tube: Cut the tip of the acrylic caulk tube at a 45-degree angle. The size of the angled hole should correspond to the size of the gap you need to fill. Start with a small hole and enlarge it gradually if needed.
- Apply the Acrylic Caulk: Run a bead of acrylic caulk along the seams, edges, or gaps in your shiplap siding. Use a steady hand to ensure an even application.
- Smooth the Caulk: Use a clean finger or a rag to smooth out the caulk, ensuring it fits neatly into the seams or gaps. Wipe away any excess caulk immediately with a lint-free rag dampened with soapy water. Allow the caulk to cure completely before proceeding.
- Paint Over the Caulk (if desired): Acrylic caulk is paintable, so you can apply a coat of paint to match your shiplap siding. Use a high-quality primer before applying your topcoat of paint for better adhesion and a uniform finish. Allow the primer and paint to dry completely before considering the job done.
By following these steps and allowing adequate curing and drying time, you can achieve a seamless and professional-looking finish on your exterior shiplap siding project.

Priming wood before painting
Wood is a super absorbent surface, similar to a canvas. If it is not properly prepared, it will absorb paint, leaving dull colours and an uneven finish. Priming wood before painting is therefore an important step to ensure a quality paint job that is long-lasting and looks great.
Priming is especially important for exterior wood painting projects, as exterior primers are designed for long-lasting results, helping to prevent cracking and erosion. However, not all primers will work well on wood, so it is important to choose a primer that is specifically designed for the type of wood being painted. For example, if the wood is new, with minimal grains and no stains, a latex primer will work fine. However, if the wood is weathered, an oil-based primer will be better. If there are tannins in the wood, an oil primer is preferable, as these can bleed through a latex primer.
Priming can also help to fill out any imperfections in the wood, such as small gaps, cracks, and knots, and will smooth out the surface, ensuring that the paint does not soak in too deeply. This will help to create a seamless look and enhance the sharpness of the paint colour. Primer will also strengthen the bond between the surface and the topcoat, reducing the number of coats of paint needed and extending the life of the paint job.
In some cases, however, priming may not be necessary. If the wood is already in good condition and has been previously painted, it may not need to be primed, as most modern quality exterior and interior paints are self-priming.

Painting shiplap with a paint sprayer
Painting shiplap is a versatile design option. You can paint it to match your desired colour scheme, or leave it as natural wood for a rustic look. Before painting, ensure your shiplap boards are free from dust, dirt, and oils. Wipe them down with a damp cloth or use a mild cleaner if necessary. If you're working with reclaimed or raw wood shiplap, lightly sand the surface with 80- to 120-grit sandpaper to remove any rough spots or imperfections.
If you're using a paint sprayer, thin your paint slightly and filter the mixture to prevent clogging. You should also cover all floors, furniture, light fixtures, and anything you don't want to be painted with plastic sheeting and painter's tape. This protects from overspray and drips. Put on protective gear, including a respirator mask, to protect your eyes and lungs from paint particles in the air.
Once the room is prepped, follow the instructions for your paint sprayer to start painting. The spraying step is surprisingly quick, but it takes time and practice to get better at using a paint sprayer. You'll need to figure out how quickly to move the sprayer to avoid overspray or underspray, and get a feel for how messy it will be.
If your shiplap will have gaps between the boards, painting the wall behind in a similar shade prevents a stark contrast from showing through. Caulk can also be used to fill in any gaps and seams, creating a seamless look. Use a high-quality primer or an initial coat of paint in your chosen colour.

Using a paintbrush for small spaces
While caulking the seams of exterior shiplap siding is not mandatory, it is recommended to fill in any gaps and seams to create a seamless look. Caulking can be easily painted over, and it helps to cover any mistakes in the installation, such as small gaps or uneven edges.
Now, for painting small spaces, the right tools will make the job much easier. First, use painter's tape to tape off everything you need to protect from paint, such as baseboards, windows, doorways, and ceilings. This is especially important in small spaces, as it can be difficult to manoeuvre and find a comfortable angle for painting. Then, even if you can't reach a space and your painting gets sloppy, your lines will remain crisp and clean once you remove the tape.
A paintbrush with a short handle is ideal for tight spots. A 2" angled brush is a good all-purpose option. If you can only have one paintbrush, this is the one to get. In small spaces, a roller might not be the best option, as it can be difficult to fit in certain areas. Mini paint rollers are available and can be a good alternative, but they may not be suitable for all small spaces.
When choosing paint for small spaces, consider using a light colour, as this can make the room look bigger. An eggshell paint finish will help repel marks, and many brands offer wipeable options.
