Here’s your step-by-step guide to getting the job done right.

Step 1: Plan Your Fence Layout

Start by measuring your boundary and sketching your design. Decide on:

• Fence height
• Post spacing (typically 1.8m)
• Whether you’re building a slatted or full privacy fence

Use a string line and pegs to mark out your line.

Step 2: Choose the Right Timber

All of our fencing battens are P.A.R, meaning they’re smooth, straight-edged, and planed on all four sides for a clean, modern look. This makes them perfect for:

• Slatted fencing
• Contemporary horizontal or vertical fences
• Screens and dividing panels

Popular profiles include:

• 20mm x 45mm (available in Western Red Cedar, Thermo Ayous, Iroko, and Far Eastern Hardwood)
• 18mm x 42mm (available in Douglas Fir and European Larch)
• 20mm x 70mm (available in Western Red Cedar, Thermo Ayous, and Far Eastern Hardwood)
• 18mm x 68mm (available in Douglas Fir and European Larch)
• 20mm x 95mm (available in Western Red Cedar, Thermo Ayous, Thermowood Pine and Far Eastern Hardwood)
• 18mm x 94mm (available in Douglas Fir)

While these are the popular sizes, there are many profiles to choose from, all naturally durable and ideal for outdoor use.

Step 3: Tools & Materials You’ll Need

• Fence posts
• P.A.R battens
• Fixings (stainless steel recommended)
• String line
• Drill/Electric screwdriver
• Spirit level + tape measure
• Spacer blocks
• Postcrete or concrete (for fence posts)
• Timber oil or UV protection (optional)

Step 4: Set Your Fence Posts

• Dig post holes at least 600mm deep for a 1.8m-high fence.
• Set posts in place using postcrete or concrete.
• Use a level and string line to ensure everything is aligned.
• Let posts cure fully before attaching any timber.

Tip: Leave a small clearance at the bottom of the fence to avoid moisture damage.

Step 5: Fix Your Battens

• Begin from one end of the fence and work across.
• Use spacer blocks to maintain even gaps between battens.
• Always pre-drill near the ends of battens to avoid splitting.
• Use a single fixing on 45mm and under, and two fixings across the width per batten for sizes 68mm and over to prevent twisting over time.

Step 6: Protect and Finish (optional)

Your timber doesn’t require treatment! In fact, many opt to not treat and allow the timber to weather beautifully to a silver-grey, but applying a UV-protective oil can help maintain their rich tones and prolong lifespan.
