What You'll Learn
Using a chisel and hammer
Removing concrete nails from the floor can be a challenging task, and it is important to take the necessary precautions to ensure your safety and avoid damage to the surrounding surface. Here is a detailed guide on using a chisel and hammer to remove concrete nails effectively:
Prepare the Necessary Tools:
Before you begin, make sure you have the right tools for the job. In this case, you will need a chisel and a hammer. It is recommended to use a masonry chisel, also known as a cold chisel, for this task. A standard claw hammer can be used, but if you have access to a framing hammer, it will provide more force when striking the chisel. Additionally, consider wearing safety gear, such as safety glasses, to protect yourself from any flying debris.
Loosen the Nail:
Place the chisel against the concrete nail, ensuring that the sharp edge of the chisel is firmly positioned against the nail. Hold the chisel steady with one hand and use the hammer to strike the head of the chisel with the other hand. Apply gradual force by striking the chisel head repeatedly. You can strike the nail from the right side and then the left side to effectively loosen it. Be cautious not to strike with excessive force, as concrete nails can be brittle and may snap off.
Pry Out the Nail:
Once the nail is sufficiently loosened, it's time to remove it. You can use the claw of the hammer to pry out the nail. Place the claw under the head of the nail and apply upward pressure to slowly pull it out. If the nail is stubborn and difficult to extract, you can gain additional leverage by placing a piece of wood, such as a 2x4, between the head of the hammer and the floor. This will provide a stronger fulcrum for prying.
Handle Remaining Nail Fragments:
In some cases, the nail may snap or break during the removal process, leaving a portion of the nail still embedded in the concrete. If this happens, don't worry. Simply reposition the chisel against the remaining nail fragment and continue striking it with the hammer until it is flush with the surface or can be easily removed with pliers. Be cautious not to strike the concrete surface directly, as this may cause unnecessary damage.
Safety Precautions:
Removing concrete nails can be hazardous due to the tension and hardness of the nails. Always wear safety glasses to protect your eyes from flying nails or concrete debris. Be mindful of your surroundings, and if there are any nearby objects or walls that could be damaged by a flying nail, consider covering them or moving them out of the way. Work carefully and deliberately, avoiding excessive force that could result in broken nails or damaged surfaces.

Cutting the nail with an angle grinder
When removing concrete nails from the floor, one of the methods you can use is cutting the nail with an angle grinder. This method is suitable when you want to avoid damaging the floor.
First, put on safety goggles and a face shield to protect your eyes from any flying sparks or nail fragments. You should also wear long sleeves and gloves to protect your arms and hands. If there is a possibility of creating dust, consider wearing a face mask.
Next, you will need to cut the nail with the angle grinder. Place the grinder's blade on top of the nail, as close to the surface of the floor as possible, and cut through the nail. Depending on the nail's thickness, you may need to make multiple passes with the grinder until you cut through it completely. If the nail is embedded in wood, you might need to cut through the wood with the grinder first to access the nail.
Once the nail is cut, it should be flush with the floor, leaving only a small hole that can be easily patched. If the nail is not flush, you can use a punch and a hammer to pound the remaining part of the nail until it is level with the floor.
Finally, clean up any debris and dust left from the cutting process. You can then patch the hole and level the surface by filling it with an appropriate material, such as cement or a floor levelling compound.

Using a pry bar
Pry bars are a common tool used to remove concrete nails from floors. However, this method can be risky and dangerous, as it may result in chunks of the floor being pulled up, and the nails coming out like bullets. It is advised to wear safety glasses when using this method, as there is a risk of the nails shattering and causing injury.
To use a pry bar, first, consider using a hammer to break the nail loose. This can be done by hitting the nail hard and straight down, perpendicular to it, with a hammer. Then, place the claw end of the pry bar under the head of the nail. Apply pressure slowly to pry the nail from the floor. If you are using a hammer, you can also try sticking one hammer with the claw around the nail and then hitting it with another hammer.
If you are removing nails from a concrete wall, you may need to use an air chisel to remove some of the concrete around the nail head first. Tightly grasp the chisel and work only around the nail head. Then, place the claw of the pry bar under the nail head and apply pressure to pry it out.
Pry bars can be used to remove powder-actuated nails as well. Most of these nails can be removed by shattering the glass that holds them with a hammer and then prying them out with a pry bar. However, this method may not always work, and you may need to use a grinder or saw to cut the nails.
When using a pry bar, it is important to be cautious and wear the necessary safety gear, such as safety glasses. The pry bar method may not always be the best option, as it can cause damage to the floor and surrounding area. It is recommended to consider other methods, such as cutting or grinding the nails, to produce smoother results.

Removing the nail with a Dremel tool
A Dremel rotary tool can be used to cut concrete nails off at the base. This method is likely to be cheaper than a dedicated grinder. It is also less likely to chip the surrounding concrete and leave large holes, which can be a risk when using a pry bar to pull out the nails.
To remove concrete nails with a Dremel tool, you will need the tool itself and some grinding discs. First, put on some safety glasses, as there is a risk of shattering and flying debris. Then, use the Dremel tool with a cutoff or abrasive wheel attachment to cut the nails off at the base.
If you are looking to save time, you could try using a large pry bar to pull out the nails. However, this method may result in larger holes that will need to be patched. Another option is to use a hammer to break the nails loose, but this may also damage the concrete floor.
The Dremel tool can also be used in conjunction with other tools. For example, you can drill a hole in the lumber next to the nail, hammer the wood in that direction, and then use the Dremel tool to cut the nail. Alternatively, you can use a saw to cut through the nails, but this may require a specialised blade as concrete nails are very hard.

Drilling the nail out
Drilling concrete nails out is a viable option, but it can be a frustrating task as they are heavy-duty, rigid, and wedge-shaped. If you have access to a Dremel or other rotary tool, you can use a cutoff or abrasive wheel attachment to cut through them. This method is effective, but it will require multiple blades as concrete nails are very hard and will dull blades quickly. It is important to note that any type of cutting wheel will throw sparks, so appropriate safety precautions must be taken.
To begin the drilling process, place the sharp end of the chisel against the nail where it meets the concrete. Then, strike the chisel with a hammer until the nail is cut or knocked loose. If you are unable to knock the nail out, you can try to loosen it by striking it from the right and then the left side with a hammer. Be sure to stop before the nail snaps off. Once the nail is loose, pull it out with the claw of a hammer.
If you are using a grinder, you can grind away some of the concrete surrounding the nail head to create more space to work with. This will allow you to patch the low spots and level the finished surface afterward. You can also use a regular hammer to remove concrete nails, but a pry bar with a claw on one end will give you more leverage. Place the claw under the head of the nail and slowly pry it from the concrete, applying pressure as you work.
It is worth noting that some nails may be more challenging to remove than others. In some cases, you may need to cut the nail flush with an angle grinder or a multi-tool. This method may result in larger chunks of concrete being removed along with the nail. If you are concerned about damaging the concrete, you can try to minimise the impact by using a smaller tool, such as a Dremel grinder, or by opting for a different method altogether, such as prying or hammering.
