Cutting Decking Nails: The Safe And Easy Way

how to cut decking nails

Removing nails from decking can be a challenging task, especially when dealing with old and stubborn nails. While some nails can be pulled out with tools like nail pullers, vice grips, or hammers, others may require more creative approaches. In some cases, cutting the nails may be the best option to remove them without damaging the wood. This can be done using various tools such as a sawzall with a metal-cutting blade, an oscillating tool, or even a grinder. However, when using a grinder, it is important to be cautious as the sparks can pose a fire hazard. Additionally, some individuals have suggested cutting the deck boards and prying off the pieces or using techniques like pounding the nail below the flush and filling the hole with wood filler.

Using a sawzall with a metal-cutting blade

Blade selection is crucial for achieving optimal results. For cutting decking nails, look for a blade with a high tooth-per-inch (TPI) count and a narrow kerf-width. A high TPI count, typically above 10 teeth per inch, ensures precise cuts and reduces the risk of the blade getting stuck or bending. Additionally, consider the length, width, thickness, and tooth pattern of the blade. Longer blades are suitable for cutting wider materials, while thinner blades provide better precision for detailed work.

When cutting nails with a Sawzall, it is important to prioritize safety. Always wear eye protection, gloves, and earplugs to shield yourself from flying debris and loud noise. Before starting, inspect the nail and its surroundings to ensure there is sufficient clearance for the blade.

To enhance the cutting process and prolong the life of your blade, consider using a lubricant like oil or wax. Lubrication helps reduce heat and friction, making it easier to cut through tough materials. Additionally, always ensure your Sawzall is securely anchored to a solid surface to minimize vibration during the cutting process.

With the right blade selection, safety precautions, and techniques, using a Sawzall with a metal-cutting blade can be an efficient and effective way to cut decking nails.

Using a hammer and nail puller

First, try to loosen the nail by tapping it with a hammer. This will help create some space between the nail and the wood, making it easier to grip with the nail puller. You can also try using a larger pry bar or a cat's paw to get under the nail head and pry it up slightly. This will give you more room to work with the nail puller.

Next, position the nail puller under the head of the nail. Ensure that the nail puller is seated far enough under the head to get a good grip. If the nail is too short, you can use a piece of pipe or a longer tool, such as a pry bar, to gain more leverage.

Now, with the nail puller securely in place, pull back firmly to extract the nail. If the nail is particularly stubborn, you can try pushing the nail puller to the side, towards the hammer handle, before resetting and going in the opposite direction. This side-to-side motion can help loosen the nail and make it easier to remove.

If you're having difficulty removing the nail with a standard nail puller, you might want to try a different type of nail puller, such as a slide hammer nail puller or a cat's paw. A slide hammer nail puller uses a sliding weight on the handle to drive the pulling teeth down next to the nail head, providing more force for extraction. A cat's paw is a type of pry bar that can be very effective at removing heavy-duty nails.

In some cases, the nail head may break off during the removal process. If this happens, you can use a pair of pliers or vice grips to grab the remaining portion of the nail and continue pulling. Alternatively, you can use a saw or grinder to cut the nail flush with the surface of the wood.

By following these steps and using a combination of tools, you should be able to effectively cut and remove decking nails using a hammer and nail puller.

Bending nails over the side with a hammer

If you are looking for a quick fix and don't mind the appearance of bent nails on the side of your decking, then this method of bending nails over the side with a hammer may be for you. This method is ideal if you are unable to remove the nails from your decking using a nail puller or other methods.

First, assess the condition of the nails. If they are old and stubborn, you may need to hit them with a hammer to loosen them before attempting to bend them. This can be done by striking the nail head with a hammer to push it further into the wood, or by using the claw of the hammer to grip the nail and pull it out slightly, making it easier to bend.

Next, take your hammer and place it on the nail head. Apply force to the hammer in the direction of the side of the decking, bending the nail over the edge. You may need to use a piece of pipe or another tool to gain leverage and help bend the nail if it is particularly stubborn.

Be cautious when bending the nails, as you don't want to accidentally hit your decking and damage the wood. Work slowly and deliberately, and consider wearing safety gear such as gloves and eye protection to avoid injury from any flying nails or splinters.

By following these steps, you can effectively bend decking nails over the side using a hammer. This method can be a quick and practical solution when other nail removal techniques are unsuccessful or too time-consuming.

Using a grinder

Firstly, it is crucial to wear appropriate protective gear, including eye protection and gloves, when using a grinder. Grinders can generate sparks, so combustible materials should be kept away from the work area, and it is advised not to leave the site immediately after using a grinder.

When using a grinder to cut decking nails, it is recommended to use a grinder with a cutoff disc or cutting wheel. This will allow you to cut through the nails efficiently. Before starting, ensure that the grinder is in good working condition and that the disc or wheel is securely attached.

To cut the nails, position the grinder's disc or wheel at the base of the nail, where it meets the decking. Apply gentle pressure and allow the grinder to do the work. Cut each nail as close to the decking as possible, and then use a hammer to pound any remaining nail stubs below the surface.

If you are concerned about sparks from the grinder, there are alternative cutting tools available, such as oscillating tools or a Sawzall with a metal-cutting blade. These tools can provide more precision and may be better suited for confined spaces or sensitive areas. However, they may require more time and effort compared to a grinder.

Using a cat's paw and hammer

To use a cat's paw and hammer effectively, follow these steps:

  • Position the cat's paw: Place the curved end of the cat's paw underneath the head of the nail. Ensure that the cat's paw is securely hooked around the nail to provide a firm grip.
  • Apply force with the hammer: Use the hammer to strike the end of the cat's paw firmly, but be cautious not to use excessive force, as this may damage the tool or the surrounding wood.
  • Pry and remove the nail: After applying force with the hammer, use the cat's paw to pry the nail out of the decking. You may need to repeat the process of striking with the hammer and prying with the cat's paw multiple times to gradually loosen and remove the nail.

It is important to note that using a cat's paw and hammer can be challenging for removing nails that are deeply embedded or corroded. In some cases, the nail head may break off, requiring alternative methods, such as using a pry bar or a grinder, to extract the remaining nail stub.

Additionally, for nails that are particularly stubborn, you can try hitting them with a hammer first to loosen them before using the cat's paw. This can help to create some initial movement, making it easier to pry them out with the cat's paw and hammer.

Frequently asked questions

Mark a square line on the nail and cut in light passes, working the full width of the board. This will keep the cut cleaner and help clear sawdust, preventing burning and keeping the blade cool.

While there are several ways to cut decking nails, using a sawzall with a metal-cutting blade is a popular method. Other methods include using a pry bar, a pitchfork, a crowbar, a cat's paw, or a nail puller.

If you don't want to damage the wood, you can pound the nail below the flush and fill the hole with wood filler. Alternatively, you can use a nail puller, which can get close to obstacles and grab onto the shaft of a nail with a broken head.

If the nails are protruding through the other side of the wood, you can pull them out with a pair of wire nippers.
