Step 1: Surface Preparation
Start by preparing the wall for cladding installation:
- Inspect the surface: Ensure it’s clean, dry, and stable.
- Attach a breathable membrane: Temporarily secure it with tape, then fix it properly using galvanized staples, nails, or screws with washers. This acts as a weather-resistant barrier and allows ventilation.
Step 2: Install the Battens
Treated timber battens are essential for supporting your cladding.
- Measure and mark: For horizontal Square Edge cladding, position vertical battens.
- Spacing: Space battens evenly, 400–600mm apart, with extra battens at corners, around windows, and along edges for additional support.
- Secure battens: Fix them securely to the wall using screws or fasteners appropriate for your wall type.
Step 3: Prepare the Square Edge Boards
- Inspect your boards: Check for any defects and let the boards acclimate to site conditions for 5–7 days to reduce movement after installation.
- Cut to size: Use a saw to trim the boards to the required length, leaving a 2mm gap at edges to allow for expansion.
Step 4: Start Cladding
Now you’re ready to start installing the boards!
- Begin at the bottom: For horizontal cladding, start at the base of the wall; for vertical cladding, begin at one side.
- Check alignment: Use a spirit level to ensure the first board is perfectly straight.
Step 5: Fix the Boards
- Secure the first board: Fix it to the battens using stainless steel screws or nails. Ensure the fixings are evenly spaced and flush with the board for a neat finish.
- Continue upwards: Attach subsequent boards, ensuring they are evenly spaced for a uniform appearance. Square Edge cladding does not overlap, so precise alignment is key to achieving a sleek finish.
Step 6: Finishing Touches
- Trim as needed: Neatly cut boards to fit around windows, doors, and other openings.
- Add trims and mouldings: Use edge trims and corner mouldings to give your project a clean, professional finish.
Step 7: Protect Your Timber
To maintain the beauty and durability of your Square Edge cladding:
- Apply a protective finish: Use an oil, stain, or paint to preserve the timber’s natural color and protect against weathering.
- Reapply as necessary: Regular maintenance will help your cladding last for years to come.
