How to Fix Shiplap Wall Cladding?

Shiplap wall cladding is a classic wall cladding material. It is characterized by the fact that the boards are connected to each other in an overlapping manner, creating tight joints. This makes it both waterproof and uniquely decorative.

Unlike traditional tongue and groove boards, shiplap cladding boards are not fully interlocking. It was originally used in outdoor buildings such as barns and farmhouses. Nowadays, it has become a popular choice for interior and exterior decoration. Composite wall cladding from EVODEK can be used to create both rustic and modern minimalist designs.

Features of Shiplap Wall Cladding

  • Waterproof: The overlapping structure can effectively block rainwater infiltration, making it suitable for outdoor use.
  • Easy to Install: No need for a complicated process, suitable for DIY enthusiasts.
  • Variety of Styles: Horizontal installation can stretch the visual width of the space, while vertical installation can increase the sense of height.
  • Rich Materials: In addition to traditional solid wood, there are also modern and environmentally friendly options, such as composite materials.

How to Install Shiplap Wall Cladding

The installation process of shiplap wall cladding is relatively simple. There are mainly the following steps:

Prepare The Tools

You can use standard carpentry tools to install shiplap wall cladding. If you need it, EVODEK can provide a full set of accessories needed for the installation, so you don’t need to buy anything else. Typically, you will use the following tools:

  • Measuring Tools: Tape measure, level, pencil
  • Cutting Tools: Circular saw, cut-off saw, or table saw
  • Fixing Tools: Nail gun, screwdriver, screws
  • Protective Equipment: Dust mask, safety goggles

Wall Treatment

  • Wall Inspection: Make sure the wall is flat and dry before construction. Concrete walls need to use expansion screws to fix joists.
  • Moisture-proof Measures: Outdoor installation needs to leave a ventilation cavity between the wall and the planks.
  • Position Marking: Use the stud finder to find the position of the studs and mark the fixing point with a pencil.

Measuring and Cutting

Calculate how much cladding is required by measuring the width of the wall. Then, make sure all shiplap cladding boards are cut to the correct length.

Normally, if you are dealing with a standard-shaped room, you can finish cutting all the shiplap cladding boards before you start. However, if you are dealing with irregularly shaped rooms (e.g. lofts), we recommend that you do this as you go along.

Layer-by-Layer Installation

After cutting, you can start installing the shiplap cladding boards. If installing horizontally, you can start from the skirting. For vertical installation, it is recommended to start with the edge boards. Use a level to calibrate. Secure the first cladding board with a nail gun or screws.

Then, attach the second cladding board to the first. Take care to ensure that the joints are tight. Secure it to the joist with self-drilling screws. The remaining pieces will be installed one by one like this. Also, review every 3-4 boards with a level to avoid tilting.

Edge Finishing

Installing the last board may require cutting to fit the remaining space. In addition, cover corners and window frames with L-shaped corners. This will enhance the aesthetics. EVODEK can supply composite materials in the same color as the wall cladding panels. They will match perfectly. You can also choose L corners for them in plastic or metal.

Installation Tips

You can choose DIY installation or look for a professional supplier to do the installation. The following installation tips may help you.

Waterproofing and Ventilation

Although shiplap wall cladding is renowned for being waterproof, correct ventilation and drainage are also important to minimize rot and extend the life of the cladding. Therefore, you can use slats to create a channel between the cladding and the wall. This is done by fixing one slat vertically to another. This channel needs to be open at the top and bottom, so leave a small gap between the floor, roof, and boards.

Fixing Options

We do not recommend the use of nails or nail guns. Screws are better suited to installing shiplap wall cladding than nails. Where composite cladding materials are used, we require pre-drilling to prevent cracking.

Responding to Thermal Expansion and Contraction

It is also important to note that shiplap cladding boards will expand and contract slightly as the temperature fluctuates. Therefore, you will need to allow for an expansion gap (at least 8mm at each end) when cutting. This can also be adjusted depending on the length of the board and the local temperature.

Building Permits

Before installation, it is recommended that you consult local building codes. Ensure compliance with legal regulations and safety standards.

Maintenance and Repair

Although shiplap cladding boards are known for their well-maintained durability, they can still be damaged by harsh weather conditions and prolonged use. EVODEK can provide you with composite cladding boards with better durability.

In general, the maintenance of shiplap wall cladding includes the following:

Cleaning

Regular cleaning of shiplap cladding boards can enhance their appearance and prolong their life. Generally, wiping with a soft cloth and detergent every 6 months is sufficient.

Protection

Strong UV rays can make the wood look dull. You need to apply UV-protective oil to maintain the color of the wood. On the other hand, using EVODEK’s composite wall cladding is an easier way.

Repairing Damage

Shiplap cladding boards may experience natural wear and tear. If a piece of shiplap cladding board has begun to break down or rot, it is vital to replace it as soon as possible. Otherwise, the rot will spread to other shiplap cladding boards. This will result in a reduced lifespan of the wall cladding and additional expense.

Conclusion

Shiplap wall cladding is the perfect choice for the outer layer of a building. It combines functionality with aesthetic value. Moreover, the installation process of shiplap cladding boards is simple. It can be done easily with some basic instructions and tips. With proper installation and maintenance, you can make your walls last for a long time.

FAQ

Can Shiplap Cladding Boards be Installed Directly on Plaster Walls?

Yes, but you need to make sure that the load-bearing capacity of the studs can be met. You can also add horizontal laths to provide support.

What is The Choice Between Composite and Solid Wood Shiplap Wall Cladding?

WPC is more weather-resistant and does not require constant maintenance. Therefore, it is especially suitable for outdoor use. Solid wood has a more natural texture but requires regular maintenance.
