How to Cut Composite Decking

Embarking on a composite decking project but not sure what the best way to cut composite decking is? You’re in for a treat. These modern materials offer durability and low maintenance, but they do require some special handling when it comes to cutting. Don’t fret, though – with the right tools and techniques, you’ll be cutting composite decking like a pro in no time. Let’s delve into the nitty-gritty of how to cut composite decking effectively and safely in your garden.

Essential Tools for Cutting Composite Decking

Before you start cutting composite decking, it’s vital to have the right tools at your disposal. Here’s what you’ll need:

Power Tools

A circular saw, mitre saw, and jigsaw should cover most of your cutting needs. Each has its strengths when it comes to cutting composite decking, which we’ll explore shortly.

Blades

Opt for fine-toothed blades designed for cutting composite decking . They’ll give you cleaner cuts and last longer.

Measuring and Marking Tools

A tape measure, set square, and pencil are indispensable for accurate cuts. Cutting composite decking is tricky enough without having to do it twice!

Safety Gear

Never underestimate the importance of safety goggles, ear defenders, and a dust mask. Cutting composite decking can cause a lot of sawdust which can cause irritation if it comes into contact with your eyes.

Preparing to Cut Composite Decking

Before you cut your composite decking, it’s important to prepare. Proper preparation can make the difference between a smooth operation and a frustrating experience.

Measure Twice, Cut Once

This age-old carpentry adage holds true for cutting composite decking. Double-check your measurements and mark your cutting lines clearly.

Create a Stable Work Environment

Set up a sturdy workbench or saw horses to support your boards. A stable surface is essential for safe, accurate cuts.

Cutting Techniques: The Heart of the Matter

Believe it or not, there’s no one best way to cut composite decking. It depends on what cut you need! So we’ll take you through the three best decking saws for cutting composite decking, what type of cutting you’ll be using them for, and some helpful techniques to use them effectively.

Wielding the Circular Saw

The circular saw is your go-to for long, straight cuts. Here’s how to use it effectively:

Depth: Set your blade depth to just barely clear the thickness of the composite board. This minimises splintering and makes for a cleaner cut.

Clamping: For perfectly straight cuts, clamp a straight edge to your board as a guide for your decking saw. This technique can save you from wobbly lines and potential mistakes.

The Mitre Saw

When it comes to angled cuts and cross cuts, the mitre saw is your best bet. Here’s how to make the most of it:

Angling: For angled cuts, set your mitre saw to the desired angle and make a test cut on a scrap piece first. This ensures accuracy before you cut your good boards.

Cross Cuts: For straight cross cuts, ensure your composite decking board is snug against the fence before making your cut. This guarantees a square edge every time.

The Jigsaw

Need to cut curves or make intricate cutouts? The jigsaw is your tool of choice. Here’s how to use it effectively:

Curving: Mark your curve clearly and take it slow. Let the decking saw do the work – don’t force it.

Splintering: To prevent splintering on the top surface, cut with the good side down when using a jigsaw.

Finishing Touches

You’ve made your cuts, but you’re not quite done yet. These final steps ensure a professional finish.

Smoothing the Edges

It’s likely you’ll have rough edges after cutting composite decking. A quick once-over with fine-grit sandpaper can smooth things out nicely. You can also purchase our border trims and skirting boards to give your composite decking a professional, polished finish.

Prepping for Installation

Ensure all your cut edges are clean and smooth before installing your decking. This not only looks better but can also prevent future issues.

Tidying Up

Clear away all debris and dust from your work area and the cut boards. A clean decking board installs more easily and looks better from the start.

Quality Control

Take a moment to inspect all your cuts. Any issues are much easier to address now than after installation.

Troubleshooting When Cutting Your Decking

Even with the best preparation, you might encounter some challenges. Here’s how to handle them:

Warping and Splintering: Prevention is Better Than Cure

To minimise warping and splintering, always support the board close to the cut line and use sharp, appropriate blades.

Expansion and Contraction: Plan Ahead

Remember that composite decking expands and contracts with temperature changes. Leave appropriate gaps during installation to accommodate this movement, especially important in the UK’s variable climate.
