How to Cut Deck Boards Around Posts

Many people wonder how to cut deck boards around posts because it can be a difficult task. The first thing you need to do is figure out the measurements of your post and measure your board accordingly.

You will want to make sure that the board is longer than the height of the post so that there are no gaps in between. Then, use a circular saw or miter saw as well as a laser level for accuracy and carefully cut through the wood from one end to another, following along where your post will go.

Lastly, fill in any gaps with additional pieces of wood if necessary and sand down all sides before painting or staining. Deck boards can be a costly investment, so it’s essential to take the time and care required to cut them around posts properly.

Step by Step Guide on How to Cut Deck Boards Around Posts

Step One: Measure the Posts

For most deck projects, your deck boards will be installed with the ends of the boards resting on top of posts. The best way to cut around posts is to measure and mark where you need to notch outboards before they are installed.

Measure the Posts

This will be an essential step because the notches need to be deep enough for the post to fit into them. The best way to measure around posts is to use a measuring tape, a carpenter’s square, and pencils.

Step Two: Make Notches on Deck Boards

Once you have the measurements of where the notch needs to be cut, place your carpenter’s square on top of the board, so one side rests next to the post, and mark out where your notches will go with a pencil.

After marking outboards, mark out corresponding boards to keep things consistent. You will want to make sure the notches are even top to bottom, side to side, and make matching notches on opposite sides of each leg.

Step Three: Cut Notches for Posts with a Circular Saw

After marking your cut lines, your next step is to cut them out using a circular saw. While it may be easier to use a jigsaw for this step, we recommend using a circular saw because the blade will have more teeth for faster cuts.

To achieve flush ends on your notches, you will want to cut about halfway through the boards, so they are easy to finish with a hand saw or sander. A circular saw with a cutting guide attachment is the best way to get straight cuts on your notches.

Step Four: Cut Notches for Posts with a Jigsaw

Using a jigsaw, make all your notches. If you are planning on finishing the notches with sanding, it is best to leave them high or cut them deeper because once you apply to finish all your work, they will be obscured.

After cutting out notches, sand down the edges, so they are sharp and smooth. Then you can sand your corners to break them up for a more finished look. You can then apply any stain or finish of your choice.

Step Five: Fill in Notches with Wood Filler

If you opted to fill the notches before finishing, use wood filler to fill in any gaps or seams within your notches. It is best to use a high-quality wood filler to get a smooth finish after it dries. After filling the notches, allow the wood filler to dry before sanding.

Use a finer grain than your original planer to get an even smoother finish—sand between each step to ensure smoothness all around the post. After filling, allow the wood filler to dry before sanding with finer grain paper than your original planer. Again, make sure to sand between each step for a smooth finish all around the post.

Step Six: Install Deck Boards

Once you have cut and filled all the notches, you can install the deck boards around your posts. Once installed, you can stain or finish the wood to match. Now that you know how to measure and notch deck boards around posts, you will be able to cut around them with ease.

Step Seven: Fill Post Holes

After installing deck boards around posts, the next step is to fill in the post holes. You want to use a mixture of sand and soil that will firm up well under pressure to do this. Again, this is best done with an electric drill to ensure even consistency throughout the hole.

This mixture can be tamped down, so it is nearly flush with the ground. Then add a layer of pea gravel to prevent weeds from sprouting up and soil on top of that. The pea gravel will also keep your boards away from the wet dirt while preventing any settling or sinking in the future.

Step Eight: Fill Holes with Sand and Soil Mixture

The mud around your posts can cause decay because it creates a damp environment. To maintain the integrity of your deck, use a mixture of sand and soil to fill in post holes. This mixture will firm up well under pressure while creating an ideal level surface for building on top.

Conclusion

Cutting deck boards is a more difficult task than it may seem at first glance. For example, suppose you’re not sure how to cut the boards around posts. In that case, we recommend using an electric saw and measuring carefully with a metal yardstick or another straight edge for every board you cut so that they all fit snugly against each other without any gaps.

This will ensure your decking looks neat and clean while ensuring safety from tripping hazards on uneven surfaces. The conclusion paragraph is informative and provides information on how to cut deck boards around posts.
