Fence Shiplap DIY: 5 Pro Tips for Perfect Wood Joinery

Shiplap fences are not only aesthetically pleasing but also offer excellent privacy and security. But achieving that perfect, seamless look requires more than just slapping boards together. It’s about understanding wood, mastering joinery techniques, and paying attention to the details. I’ve spent years working with wood, from felling trees to milling lumber, and I’m here to guide you through the process, sharing my hard-earned knowledge and pro tips to help you build a shiplap fence that will stand the test of time.

1. Selecting the Right Wood: It’s All About the Foundation

The foundation of any great project starts with the right materials. Choosing the appropriate wood for your shiplap fence is crucial for its durability, appearance, and longevity.

Understanding Wood Types for Fencing

Different wood species offer varying levels of resistance to rot, insects, and weathering. Here’s a breakdown of some popular choices:

Cedar: This is my personal favorite. Cedar is naturally resistant to decay and insects, making it an excellent choice for outdoor projects. It also has a beautiful reddish-brown color that weathers gracefully to a silver-gray. Western Red Cedar and Alaskan Yellow Cedar are common varieties. I’ve used cedar for countless projects, and its durability always impresses me.
Redwood: Similar to cedar, redwood is naturally resistant to decay and insects. It’s known for its rich color and stability. However, it can be more expensive than cedar, depending on your location. I once salvaged some redwood from an old water tower, and it was still in fantastic condition after decades of exposure.
Pressure-Treated Pine: This is a more affordable option. Pine is treated with chemicals to resist rot and insects. While it’s a good choice for structural components like fence posts, I often prefer cedar or redwood for the shiplap boards themselves. I’ve seen pressure-treated pine last for years, but it doesn’t have the same natural beauty as cedar or redwood.
Cypress: Another naturally durable wood, cypress is resistant to decay and insects. It has a distinctive grain pattern and a lighter color than cedar or redwood. I’ve used cypress for garden beds and found it to be a reliable and attractive option.

Grading and Quality: Not All Boards Are Created Equal

Beyond the species of wood, the grade and quality are crucial. Look for boards with minimal knots, straight grain, and consistent thickness.

Select Grade: This is the highest quality, with few or no knots. It’s the most expensive but provides the cleanest look.
Common Grade: This grade has more knots and imperfections but is more affordable. It can still be used for shiplap fencing, but you’ll need to be more selective when choosing your boards.
Construction Grade: This is the lowest grade and is typically used for structural components. I wouldn’t recommend using it for shiplap boards, as it may have excessive imperfections.

My Experience: I remember once trying to save money by buying a lower grade of cedar. Big mistake. The knots were so frequent and large that I ended up wasting a lot of wood trying to cut around them. In the end, I spent more time and effort, and the finished fence didn’t look as good. Lesson learned: invest in quality wood.

Moisture Content: Drying is Key

The moisture content of your wood is critical. Wood that is too wet will shrink as it dries, leading to gaps in your shiplap fence. Ideally, you want wood with a moisture content between 12% and 15%.

Kiln-Dried Lumber: This lumber has been dried in a kiln to reduce its moisture content. It’s the most stable option and is less likely to warp or shrink.
Air-Dried Lumber: This lumber has been air-dried, which is a slower process. It may still have a higher moisture content than kiln-dried lumber, so you’ll need to let it acclimate to your local climate before installation.

Pro Tip: Use a moisture meter to check the moisture content of your wood before you start building. This simple tool can save you a lot of headaches down the road. I use a Wagner MMC220, but there are many affordable options available.

Takeaway: Choosing the right wood is the first step to a successful shiplap fence project. Consider the species, grade, and moisture content to ensure durability and a beautiful finished product.

2. Mastering the Overlap: Achieving the Perfect Reveal

The hallmark of a shiplap fence is its overlapping boards, creating a distinctive shadow line. Achieving the perfect overlap, or “reveal,” is essential for both aesthetics and functionality.

Determining the Reveal: Finding the Sweet Spot

The reveal is the amount of each board that is exposed. A typical reveal for shiplap fencing is between 1 and 2 inches. The exact amount depends on the width of your boards and your personal preference.

Narrow Boards (4-6 inches wide): A 1-inch reveal is a good starting point.
Wider Boards (8-12 inches wide): You can increase the reveal to 1.5 or 2 inches.

My Insight: I’ve found that a slightly larger reveal can create a more dramatic shadow line, especially on fences with a simpler design. But be careful not to go too large, as it can reduce the overall coverage of the fence.

Creating Consistent Spacing: Jigs and Spacers

Maintaining consistent spacing between the boards is crucial for a professional-looking fence. Here are a few techniques I use:

Jigs: A jig is a simple tool that helps you position the boards at the correct spacing. You can make a jig out of scrap wood by cutting a piece to the desired reveal width. Simply place the jig on top of the previous board and align the next board against it.
Spacers: Pre-made spacers are available at most hardware stores. These are small pieces of plastic or wood that you insert between the boards to maintain consistent spacing.
Story Stick: A story stick is a piece of wood marked with the desired spacing. You can use it to quickly mark the location of each board.

Case Study: I once built a shiplap fence for a client who insisted on a perfectly uniform reveal. I used a combination of jigs and spacers to ensure that every board was precisely positioned. The result was a stunning fence with a flawless finish.

Calculating Board Quantity: Planning is Paramount

Before you start cutting and installing boards, it’s essential to calculate how many you’ll need. Here’s the formula:

Measure the total height of the fence.
Determine the width of your shiplap boards.
Decide on the reveal.
Calculate the exposed width of each board (board width – reveal).
Divide the total fence height by the exposed width of each board.
Add a few extra boards for waste and mistakes.

Example:

Fence Height: 6 feet (72 inches)
Board Width: 6 inches
Reveal: 1 inch
Exposed Width: 5 inches
Number of Boards: 72 inches / 5 inches = 14.4 boards

Round up to 15 boards and add a few extra, so you’ll need approximately 17-18 boards per section.

Takeaway: Mastering the overlap is key to a beautiful shiplap fence. Use jigs, spacers, or a story stick to ensure consistent spacing, and calculate the number of boards you’ll need before you start building.

3. Choosing the Right Fasteners: Secure and Invisible

The fasteners you use to attach the shiplap boards to the fence frame are crucial for both the structural integrity and the appearance of your fence. You want fasteners that are strong, durable, and as invisible as possible.

Screw vs. Nail: The Great Debate

There’s an ongoing debate about whether screws or nails are better for shiplap fencing. Here’s my take:

Screws: Screws provide a stronger, more secure hold than nails. They’re less likely to loosen over time, and they can be easily removed if you need to replace a board. I prefer screws for most shiplap fencing projects.
Nails: Nails are faster to install than screws, but they don’t provide as much holding power. They’re also more likely to loosen over time, especially in windy areas. However, if you’re using a pneumatic nail gun, nails can be a convenient option.

My Preference: I always opt for screws, especially when working with cedar or redwood. The extra holding power is worth the effort, in my opinion.

Fastener Types: Choosing the Right Tool for the Job

When using screws, consider these options:

Deck Screws: These are designed for outdoor use and are coated to resist corrosion. Look for screws with a star drive (Torx) head, as they’re less likely to strip.
Stainless Steel Screws: These are the most corrosion-resistant option, but they’re also the most expensive. I recommend using them in coastal areas or anywhere with high humidity.
Trim Screws: These screws have a small head that is designed to be countersunk, making them less visible. They’re a good choice for shiplap fencing where you want a clean, seamless look.

When using nails, consider these options:

Galvanized Nails: These nails are coated to resist corrosion. They’re a good choice for most outdoor applications.
Stainless Steel Nails: These nails are the most corrosion-resistant option.

Pro Tip: Always use fasteners that are compatible with the type of wood you’re using. For example, avoid using galvanized fasteners with redwood, as they can react and cause staining.

Installation Techniques: Ensuring a Secure Hold

Proper installation is just as important as choosing the right fasteners. Here are a few tips:

Pre-Drilling: Pre-drilling pilot holes can prevent the wood from splitting, especially when working with hardwoods.
Countersinking: Countersinking the screws will make them less visible and prevent them from interfering with the overlapping boards.
Staggering Fasteners: Staggering the fasteners will distribute the load more evenly and prevent the boards from warping.

My Experience: I once rushed through a shiplap fence project and didn’t pre-drill the holes. The cedar split in several places, and I had to replace a few boards. Lesson learned: take your time and do it right.

Takeaway: Choosing the right fasteners and installing them properly is essential for a strong, durable, and beautiful shiplap fence. Opt for screws over nails, use corrosion-resistant fasteners, and take your time with the installation.

4. Finishing Touches: Protecting Your Investment

Once your shiplap fence is built, it’s time to protect your investment with a finish. A good finish will not only enhance the appearance of your fence but also protect it from the elements.

Stain vs. Paint: Enhancing or Transforming

The choice between stain and paint depends on the look you want to achieve and the type of wood you’re using.

Stain: Stain enhances the natural beauty of the wood while allowing the grain to show through. It also penetrates the wood, providing better protection against moisture. I prefer stain for cedar and redwood, as it highlights their natural beauty.
Paint: Paint covers the wood completely, hiding the grain. It provides a more uniform look and can be used to match your house or other outdoor structures.

My Recommendation: If you’re using cedar or redwood, I recommend using a stain. If you’re using pressure-treated pine, you may want to consider paint to cover the green tint.

Choosing the Right Finish: Protection and Longevity

When choosing a finish, consider these factors:

UV Protection: Look for a finish that contains UV inhibitors to protect the wood from the sun’s harmful rays.
Water Repellency: A water-repellent finish will prevent moisture from penetrating the wood, reducing the risk of rot and decay.
Ease of Application: Some finishes are easier to apply than others. Consider your skill level and the size of your fence when making your choice.

Pro Tip: Always test the finish on a small, inconspicuous area before applying it to the entire fence. This will allow you to see how the finish looks on the wood and ensure that you’re happy with the color.

Application Techniques: Achieving a Smooth, Even Finish

Proper application is key to a long-lasting finish. Here are a few tips:

Clean the Wood: Before applying the finish, make sure the wood is clean and dry. Remove any dirt, dust, or debris.
Sand the Wood: Lightly sanding the wood will create a smooth surface for the finish to adhere to.
Apply Thin Coats: Apply several thin coats of finish rather than one thick coat. This will prevent drips and runs and ensure a more even finish.
Follow the Grain: When applying the finish, always follow the grain of the wood.

My Experience: I once applied a thick coat of stain to a shiplap fence, and it took forever to dry. The finish was uneven and blotchy. I had to sand it down and start over. Lesson learned: thin coats are always better.

Takeaway: Finishing your shiplap fence is essential for protecting your investment and enhancing its appearance. Choose the right finish for your wood type and desired look, and apply it properly for a long-lasting result.

5. Addressing Common Challenges: Troubleshooting Tips

Even with the best planning and execution, you may encounter challenges when building a shiplap fence. Here are a few common problems and how to address them:

Warping Boards: Prevention and Correction

Warping is a common problem with wood, especially in humid climates. Here’s how to prevent and correct it:

Prevention: Choose kiln-dried lumber with a low moisture content. Store the lumber in a dry, well-ventilated area before installation.
Correction: If a board warps after installation, you can try to straighten it by clamping it to a straight edge and applying heat with a heat gun or hair dryer. You can also try adding additional fasteners to hold the board in place.

My Insight: I’ve found that storing lumber properly is the best way to prevent warping. Stack the boards with stickers (small pieces of wood) between them to allow for air circulation.

Splitting Wood: Preventing Cracks

Splitting can occur when driving screws or nails into the wood, especially near the ends of the boards. Here’s how to prevent it:

Pre-Drilling: Always pre-drill pilot holes before driving screws or nails.
Using Sharp Fasteners: Use sharp screws or nails that will cut through the wood cleanly.
Avoiding Over-Tightening: Avoid over-tightening screws, as this can cause the wood to split.

Pro Tip: If you’re working with a particularly brittle wood, you can try dipping the screws or nails in beeswax before driving them in. This will lubricate the fastener and reduce the risk of splitting.

Uneven Spacing: Maintaining Consistency

Maintaining consistent spacing between the boards can be challenging, especially on long fence runs. Here’s how to address uneven spacing:

Jigs and Spacers: Use jigs and spacers to ensure consistent spacing.
Adjusting as You Go: Check the spacing frequently and make adjustments as you go.
Using a Level: Use a level to ensure that the boards are aligned properly.

Case Study: I once built a shiplap fence on a sloped property. Maintaining consistent spacing was a nightmare. I ended up using a laser level to ensure that the boards were aligned properly.

Rot and Decay: Protection is Key

Rot and decay are the biggest threats to a wood fence. Here’s how to protect your fence:

Choosing Durable Wood: Choose wood that is naturally resistant to rot and decay, such as cedar or redwood.
Applying a Finish: Apply a water-repellent finish to protect the wood from moisture.
Maintaining the Finish: Reapply the finish every few years to maintain its protective properties.
Proper Drainage: Ensure that the fence is properly drained to prevent water from pooling around the base.

Takeaway: Building a shiplap fence can be challenging, but with the right knowledge and techniques, you can overcome these common problems and build a fence that will last for years to come.
