Composite cladding installation is a DIY upgrade that anyone can do. With the right tools, equipment, and materials at hand, you’ll be surprised at how simple and easy it is to give your indoor or outdoor space a new lease of life.
If you’re ready to take on the task, this guide will tell you everything you need to know about how to install composite cladding. No frills, no fuss, just simple instructions for excellent results!
Step 1: Prepare, Measure & Plan
Smooth, stress-free DIY processes always begin with preparation. Before you reach for your tools, it’s essential to plan first for the best results. This includes:
• Measuring the area you’d like to clad: Write down the height and width of the area you’d like to cover. This will tell you how many cladding boards, trims, and fixings you’ll need.
• Choosing your cladding installation method: Will you choose to install your cladding using clips and screws? Or will you choose a strong, heavy-duty adhesive?
We recommend only using the adhesive installation method if you’re working on a very flat, dry wall. If your wall is not flat, opt for the click and screw method. Don’t worry, we’ll talk you through both options in this guide.
• Plan your layout: If you’ve never installed composite cladding before, we recommend choosing either a horizontal or vertical design. They’re simple, effortless, and look amazing.
Step 2: Gather Your Tools And Materials
The materials you’ll need for your composite cladding installation depend on the method you’ve chosen.
For Both Methods:
- A tape measure and a pencil
- A spirit level
- A saw (we recommend a jigsaw or a circular saw)
- PPE (gloves and goggles)
For The Clip And Screw Method:
- Cladding joists (structural supports that go onto the wall first)
- A drill
- Stainless steel screws
- Starter clips and fixings
- Cladding trims for corners and edges
For The Adhesive Method:
- Construction-grade adhesive
- Caulking gun
- Sandpaper and primer (optional — can help the glue adhere better)
Step 3: Prepare The Wall
One more preparation step, and you’ll be well on your way to installing your composite cladding.
For The Clip And Screw Method:
Screw your cladding joists onto the wall vertically. Aim to keep each one 30-60cm apart from the next, depending on the size of your wall. These joists serve as a frame for fixing the cladding onto, and can also help reduce damp and moisture build-up.
Plus, leaving a sufficient distance between each board will allow for any shrinkage or expansion during hot or cold weather.
For The Adhesive Method:
Double-check that your wall is clean, dry, and completely flat. As a precaution, brush off any loose paint, dust, or debris that could be stuck to the wall. At this point, you may also need to prime the wall (if suggested by the glue manufacturer).
Step 4: Start Installing
Now you’re ready to start your composite cladding installation. Our best advice would be not to rush. Take your time with the first few boards until you feel more comfortable and confident, and try to maintain a level positioning throughout.
For The Clip And Screw Method:
• Attach the starter/end clips provided with your Modern Garden composite cladding boards to the bottom of each joist (not board). These are designed to hold your board in place and keep it even.
• Install cladding trims by screwing them into the joists for a flawless, aesthetic finish. They can also protect your composite cladding boards from weather, moisture, and insects.
• Slot your first board into the starter/end clips, ensuring it sits straight either vertically or horizontally.
• Continue installing the remaining cladding boards and secure them using hidden clips and screws to the joists.
For The Adhesive Method:
• Draw a straight, level line along the base of the wall to act as a guide. You can use a spirit level to support you with this.
• Glue your cladding trims directly to the wall.
• Apply the adhesive to the back of the first cladding board (not all at once), and press it firmly to the wall, using your guideline as a reference.
• Continue until your composite cladding installation is complete!
