✨ Composite Decking Tips & Tricks: Getting the Perfect Finish ✨
Thinking about installing composite decking? A great-looking deck starts with the right preparation, the right tools, and a few trade secrets 🔨
Here are our top tips for a smoother install:
📏 1. Plan before you cut
Measure twice, cut once! Spend time mapping your board layout, checking joins, and planning your starter boards before installation begins.
🛠️ 2. Don’t skip the subframe
A strong deck starts underneath. Make sure your joists are level, straight, and spaced correctly to support your decking boards and prevent movement over time. Most composites require 400mm joists so make sure you have the right spacing for your composite boards.
↔️ 3. Allow for expansion gaps
Composite decking expands and contracts with temperature changes. Leave the correct spacing between boards, edges, and fixed points to keep your deck looking its best.
🔩 4. Use the right fixings
Hidden clips give a clean, seamless finish — but correct placement is key. Over-tightening screws can restrict movement and damage boards. For composites that require plugs a plug cutter is a game changer for that clean seamless finish!
☀️ 5. Consider board direction
Think about how sunlight hits your outdoor area and how you want the finished deck to look. The right direction can make your space feel larger and more open.
🧹 6. Keep airflow underneath
Good ventilation under your deck helps reduce moisture build-up and keeps your deck performing for years to come.
✨ 7. Finish the details
The difference between a good deck and a great deck is in the details — clean edges, neat cuts, fascia boards and careful alignment.
Composite decking is designed for low maintenance and long-lasting style — but a quality installation is what brings it all together.
