Removing square nails from floorboards can be a challenging task, often requiring various tools and techniques. The specific approach may depend on factors such as the type of nail, the condition of the wood, and the extent of damage one is willing to accept to the surrounding area. Common methods include using a curved claw hammer, a grinder, a pneumatic nail removing device, or a combination of tools and techniques to pry the nails out.

What You'll Learn
Using a curved claw hammer
Removing square nails with a curved claw hammer is a simple process that requires a few steps. Curved claw hammers are the most common type for general carpentry and household use, as they provide excellent leverage for nail removal and reduce the risk of damaging the surrounding area.
To begin, ensure you have the correct protective gear, such as protective eyewear, to prevent any injuries. Next, position the curved part of the claw on the hammer onto the wood surface, directly over the nail head. Gently tap the hammer handle or use the striking face of the hammer to drive the claw under the nail head. Check that the claw has a secure grip on the nail head before proceeding. Place a small piece of scrap wood, a shim, or a thick piece of cardboard under the hammerhead to act as a protective layer and distribute pressure evenly, preventing damage to the surface.
Hold the hammer handle firmly and, if necessary, gently rock the hammer back and forth while pulling to loosen the nail's grip on the wood fibres. Apply steady and controlled pressure to pull the nail out, avoiding any sudden force that could damage the wood. If the nail resists, try wiggling or tapping it with a gentle side-to-side motion to loosen it before pulling again. With the right technique, patience, and precision, you can effectively remove square nails using a curved claw hammer.

Drilling a small hole next to the nail
To do this, you will need a drill with a small drill bit (approximately 1/8” or 3mm). Position the drill bit next to the nail head and begin drilling. Drill a series of tightly spaced holes around the edge of the nail head. Continue drilling around and around, using the drill bit like a milling tool, to remove as much wood fibre as possible from around the nail shank. Be careful to avoid the drill bit snagging on the nail shank as you work.
Once you have removed the wood around the nail, you can then pull out the nail with a wrecking bar or similar tool. If you are removing floorboards, you may need to lift the whole floorboard and then knock the nail out from the other side.
After removing the nail, you will be left with large holes in the wood. To fix this, you can drill a larger hole through the damaged area and glue a piece of dowel into it. Once the glue is dry, you can sand, saw, plane, or chisel the excess dowel until it is flush with the surrounding wood.

Using a grinder
First, select an appropriate grinder for the task. An angle grinder with a very thin cutoff blade is ideal for this purpose. Choose the lightest grinder available to facilitate easier handling and manoeuvrability during the process. Ensure you have the necessary safety gear, including eye and ear protection, to safeguard yourself from any potential hazards associated with power tools.
Next, position the grinder's blade just below the bottom surface of the flooring or wood. This placement will allow you to cut off the nail without damaging the surrounding surface. Start the grinder and carefully apply pressure to the nail, allowing the blade to cut through it. Use slow and controlled movements to ensure precision and avoid any unintended contact with the wood.
As you work, be mindful of the nail's integrity. Old nails, especially those with a bit of rust, may be more prone to breakage. Adjust your technique accordingly to prevent any unexpected snapping that could damage the wood. Additionally, consider the nail's position and depth before proceeding. If the nail is only slightly exposed, grinding may be the most efficient method to minimise damage to the surrounding material.
The grinder method is advantageous due to its speed and efficiency. Once you have mastered the technique, you will find that grinding through nails is much faster than alternative approaches. However, it is crucial to exercise caution and maintain a firm grip on the grinder to prevent accidental slips that could mar the finished surface.
By following these steps and taking the necessary safety precautions, you can effectively utilise a grinder to remove square nails from floorboards or recycled wood while minimising potential damage to the surrounding materials.

Levering the nail out with nippers
Levering a nail out with nippers is a good method for removing nails from recycled wood. It can also be used to remove nails from floorboards without causing too much damage to the wood.
Firstly, grab the nail on the back side with nippers. This is best done with a curved claw hammer, as straight claw hammers can slip and damage the surface. The pressure point for leverage should be the tongue and not the finished face of the flooring or wainscoting.
Next, lever the nail out with the nippers. The head will pull through with little damage to the wood. If the nail is stuck, you can use the technique of rocking the hammer sideways, using the claw edge as a pivot point. Repeat the process until you pry out the nail.
If the nails are old and brittle, you may be able to simply hammer them flat and they will break off. Alternatively, you could try using a grinder to cut the nails off just below the bottom surface of the flooring. This method can cause damage to the wood, so it is important to use eye and ear protection.

Pneumatic nail removing device
Removing square nails from floorboards can be a challenging task, often requiring creative techniques to avoid damaging the wood. While there are various methods for tackling this problem, a pneumatic nail removing device offers a fast, efficient, and labour-saving solution.
A pneumatic nail remover, such as the NuMax SPNNR Pneumatic Punch Nailer/Nail Remover, is a powerful tool designed to punch straight or bent nails out of wood. This air-powered device is compatible with nails from 9 to 14 gauge and can quickly remove nails while preserving the quality of the wood. Its ergonomic design features a comfort grip handle that reduces user fatigue and enhances control. Additionally, its adjustable 360-degree exhaust allows for convenient airflow direction away from the user's face.
When using a pneumatic nail remover, it is crucial to ensure the tool is compatible with the size and type of nails you are dealing with. In the case of square nails, they are often the old-style "cut" nails found in floorboards and skirting boards. These nails can be particularly stubborn and challenging to remove without damaging the surrounding wood.
To use a pneumatic nail remover effectively, you should consult the manufacturer's instructions for safety precautions and proper usage guidelines. Ensure the tool is connected to an appropriate air supply and follow the recommended techniques for positioning and operating the device. With its powerful punching action, a pneumatic nail remover can quickly extract square nails, making it a valuable tool for DIY enthusiasts and professional construction contractors alike.
While a pneumatic nail removing device offers a swift solution, it may not be accessible or affordable for everyone. Alternative methods for removing square nails include using a curved claw hammer, grinding or snapping the nails, employing a long pry bar, or utilising specialised tools designed for nail extraction. Each approach has its advantages and considerations, and the best method may vary depending on the specific circumstances and the condition of the nails and surrounding materials.

Use a curved claw hammer to pry out the nail. Rest the hammer on a small block to protect the finished surface of the floorboard. If the nail is stuck, try drilling a small hole next to the nail to release the pressure and make it easier to remove.
Use a pneumatic nail-removing device. This shoots nails out with much less labour.
Use an angle grinder with a very thin cutoff blade to cut the nails off just below the bottom surface of your flooring.
Use channel locks to peel out loosened nails. This method is similar to using nibblers, but the issue with nibblers is that the hardened edge can chip if you bite down too hard.
