How to Install Shiplap Cladding Like a Pro
Shiplap cladding is the envy of Pinterest boards everywhere, being a versatile and stylish choice for finishing both interior and exterior walls. While generally left for professionals, adding Shiplap cladding boards to your home is a perfect diy-friendly project.
Shiplap cladding offers excellent weather resistance and a classic aesthetic, while being relatively low maintenance. Whether you're updating a shed, garden building, or home facade, installing shiplap properly is essential for a polished, long-lasting result. In this guide, we’ll walk you through each step, so you can tackle your shiplap installation project with confidence.
Why Choose Shiplap Cladding?
Shiplap cladding is known for its overlapping profile that creates a subtle shadow line, adding depth and character to your project. Its design helps protect against the elements by providing excellent water runoff, making it ideal for outdoor applications. It’s easy to install, durable, and suits a wide range of architectural styles.
Tools and Materials You’ll Need
Before you get started, gather the following:
- Shiplap cladding boards
Please note at Ruby, we currently only stock boards that are designed for external cladding. Don't forget your corner trim to complete the look. - Treated timber battens: Provide a secure foundation for attaching your cladding.
- Fixings: Use stainless steel screws or nails to prevent corrosion.
- Breathable membrane: Prevents moisture ingress while allowing ventilation to avoid rot.
- Drill or nail gun: For quick and secure fixing.
- Saw (hand or power): To cut boards to the required size.
- Spirit level and tape measure: Ensures your cladding is straight and accurately cut.
- Weatherproof finish: Oil or stain (optional but recommended).

Step 1: Surface Preparation
Start by preparing the wall where the cladding will be installed.
- Inspect the surface: Ensure it’s clean, dry, and structurally sound.
- Attach a weatherproof membrane: Temporarily secure it with tape, then fix it properly with galvanized staples, nails, or screws with washers. This will act as a moisture barrier and promote ventilation.
Step 2: Install the Battens
Treated timber battens are essential for creating a framework to support your cladding.
- Measure and mark: Position vertical battens for horizontal shiplap cladding.
- Spacing: Space battens 400–600mm apart and add extra battens around windows, doors, and corners for reinforcement.
- Secure battens: Use screws or fixings suitable for your wall type to firmly attach them.
Step 3: Prepare the Shiplap Boards
- Inspect your boards: Check for any defects and allow the boards to acclimate to site conditions for 5–7 days. This minimises movement after installation.
- Cut to size: Use a saw to cut the boards to the required length, leaving a 2mm gap at edges for expansion.
Step 4: Start Cladding
Now you’re ready to begin installing the boards!
- Start at the bottom: For horizontal shiplap, begin with the first board at the base of the wall.
- Position correctly: Ensure the overlap of the boards faces downward to shed water.
- Check alignment: Use a spirit level to ensure the first board is perfectly straight.
Step 5: Fix the Boards
- Secure the first board: Fix the board to the battens using stainless steel screws or nails. Place the fixings through the overlapping edge for a discreet finish.
- Overlap and repeat: Install the next board so it overlaps the first, creating a consistent shadow line. Repeat until the wall is covered.
Step 6: Finishing Touches
- Cut to fit: Neatly trim boards around windows, doors, and other openings for a polished look.
- Add trims and mouldings: Use corner trims and edge mouldings to give the installation a professional finish.
Step 7: Protect Your Timber
To enhance the durability and appearance of your shiplap cladding:
- Apply a protective finish: Use an oil, stain, or paint to preserve the timber’s natural colour and protect against weathering.
- Reapply as needed: Regular maintenance will keep your cladding looking great for years to come.
