6. How to Cut Angled Decking Boards
Welcome to the sixth section of our blog on how to cut composite decking! In this section, we’ll be showing you how to cut angled decking boards for those angled areas of your deck. But before we begin, let’s recap what we’ve learned so far.
In the previous sections, we introduced you to composite decking and the tools required for cutting it. We also discussed how to prepare your work area, measure and mark your decking boards, and make clean cuts with a circular saw or miter saw. Additionally, we covered how to cut notches and curves in composite decking and finish the cut edges.
Now, let’s focus on angled decking boards. To start, you’ll need to determine the angle of your cut. You can use a protractor or angle finder to do this. Once you have your angle, adjust your saw accordingly, either by tilting the blade of your circular saw or changing the angle of your miter saw.
Next, mark your board using a quick square and a pencil. If you’re using a miter saw, you can use the laser guide to ensure that you’re cutting at the correct angle. Remember to leave a little extra length on your board so you can trim it to the exact length later when you’re fitting it to your deck.
When making angled cuts on composite decking boards, it’s important to go slowly and carefully. Composite decking is prone to chipping, so slow down your saw to prevent unnecessary damage. Additionally, make sure your board is securely clamped down before making your cut.
Once you’ve made your angled cut, you can use fine-grit sandpaper to smooth the edges of the board. This will ensure a perfect fit when placing it on your deck. And don’t forget to clean up any debris from your work area before moving on to the next step.
In conclusion, cutting angled decking boards is very similar to cutting straight and angled boards. By following these easy steps, you’ll have perfectly shaped boards for your deck in no time! Remember to take safety precautions, go slowly and carefully, and enjoy your new beautiful deck!
7. Cutting Notches and Curves in Composite Decking
If you want to add a bit of style to your composite decking, you may want to consider creating notches or curves. Notches can be used to fit around posts or other obstructions, while curves can work great for a more unique design. To start, you’ll need to mark the area where you want the notch or curve to be. Use a chalk line to ensure straight lines or curves, and then you can start cutting.
For notches, you can use a jigsaw or handsaw to make the cuts. Make sure that you use the proper blade, and start with a pilot hole to prevent any splintering or damage. Be careful, as the composite decking material can be tough to cut through, so take your time and work carefully. When you’re finished, you can sand any rough edges and clean up the area.
For curves, you’ll need to plan and use the proper tools. Many composite decking manufacturers offer rim boards that can be bent using kerfed cuts, so check with your manufacturer to see what’s available. You can also use a circular saw set to full depth to cut across all of the deckings at once. This helps ensure a consistent curve.
Remember to always wear protective gear, including gloves and eye protection, when cutting composite decking. Take your time and work carefully, and you’ll be able to create a beautiful deck design that you can enjoy for years to come.
8. Finishing the Cut Edges
Now that you have successfully cut your composite decking, it’s time to finish up the cut edges. The finishing process is important for both aesthetic purposes and to ensure that the cuts are protected from potential water damage. To finish the cut edges, you have a couple of options.
First, you can use a router and a round-over bit to smooth out the edges. This will give them a more polished appearance and make them less sharp. If you choose to use a router, make sure to follow the safety guidelines and use a dust mask and eye protection.
Alternatively, you can use sandpaper to smooth out the edges. Start with a coarse grit, such as 60 or 80, and work your way up to a finer grit, such as 220. This will take a bit more time and effort, but it’s a budget-friendly option that can still yield good results.
Once you’ve finished smoothing out the edges, you can apply a sealant or paint to protect them from moisture. Just make sure to follow the manufacturer’s instructions and allow the sealant or paint to fully dry before using your deck.
Finishing the cut edges of your composite decking will give your decks a clean, professional look while also protecting them from water damage. With a few simple tools and some attention to detail, you can easily tackle this final step in the installation process.
