What You'll Learn
Use a chisel and hammer
Removing concrete nails can be a challenging task, especially when dealing with heavy-duty and rigid nails designed specifically for concrete. One effective approach to nail removal is to use a chisel and hammer. Here's a detailed guide on how to tackle the job:
Prepare Your Tools and Work Area:
Before starting, ensure you have the necessary tools: a sharp chisel, a hammer, and safety gear, such as gloves and goggles. The work area should be well-ventilated, and it is recommended to lay down a drop cloth or tarp to catch any debris or falling concrete chunks.
Loosening the Nail:
Start by placing the flat side of the chisel against the nail head. Hold the chisel firmly and strike it with the hammer using moderate force. Alternate between striking the right and left sides of the nail, being careful not to strike the concrete surface directly. The goal is to loosen the nail without damaging the surrounding concrete.
Extracting the Nail:
Once the nail is sufficiently loosened, use the claw end of the hammer to grip the nail head and pull it out. If the nail is stubborn and doesn't come out easily, you can use the chisel to gain more leverage. Place the sharp edge of the chisel against the nail, where it meets the concrete, and strike the chisel with the hammer. This should help cut through the nail or knock it loose.
Handling Frustrating Nails:
Some nails may prove particularly challenging to remove. In such cases, you can try tapping the chisel constantly with the hammer, applying gentle but persistent force. If the nail still doesn't budge, you may need to consider other methods or tools, such as a grinder or cut-off wheel to cut the nail off or a large pry bar to pull it out, although these methods may result in larger holes or chipped concrete.
Safety and Surface Considerations:
Always wear safety goggles and gloves when working with concrete and nails. Be mindful that using a chisel and hammer carries a risk of chipping or damaging the concrete surface. If the concrete surface is particularly delicate or prone to chipping, you may need to explore alternative methods or seek professional advice.

Heat the adhesive with a blow dryer
To remove No More Nails from concrete, one method is to heat the adhesive with a blow dryer. This method is best for urethane-based adhesives, which are the most common type. The heat will soften the adhesive, allowing you to scrape most of it off.
To begin, set your blow dryer to its highest temperature setting. You'll want to get the adhesive as hot as possible, ideally above 140°F, so that it softens enough to be easily scraped. Hold the blow dryer around 2 inches away from the adhesive, and maintain this distance as you heat the area. Keep the blow dryer in constant motion, moving it back and forth to ensure even heating.
As the adhesive heats up, you may notice it becoming softer and more pliable. Once it reaches the ideal temperature, you can begin the scraping process. Using a putty knife or a flat-edged tool, start at one corner of the adhesive and work your way across, applying even pressure to scrape it off. You may need to reheat the adhesive periodically to maintain its softened state, so keep the blow dryer on hand throughout the process.
It's important to wear safety gloves when handling the blow dryer and scraping tool to protect your hands from the heat and any sharp edges. Additionally, be cautious of the surface you are working on, as excessive heat can damage certain materials. Always test the blow dryer on a small area first to ensure it won't cause any damage.
While heating the adhesive with a blow dryer is an effective method, it may not remove all the adhesive in one go. You may need to repeat the process or use additional methods, such as coating the remaining adhesive with petroleum jelly or mineral spirits, to fully remove it.

Use a wire saw and screwdrivers
Removing No More Nails from concrete can be a challenging task, but with the right tools and techniques, it can be accomplished. One effective approach is to use a wire saw and screwdrivers. Here is a step-by-step guide on how to remove No More Nails from concrete using this method:
Gather the Necessary Tools
First, ensure you have the required tools and safety equipment. You will need a wire saw, specifically Windshield Cut-Out Wire or music wire, which can be purchased at automotive parts stores. Additionally, you will need two screwdrivers, heavy-duty safety gloves, and safety goggles or a face shield.
Prepare the Wire Saw
Cut a length of the wire to be about two to three feet longer than the width of the bonded area. If you plan to use handles, connect them to the wire by wrapping the ends of the wire around some wooden dowels or sticks. This will provide a sturdy grip and help protect your hands. If you don't use handles, wearing heavy safety gloves is essential to protect your hands from the sharp wire.
Start Sawing
Position the middle of the wire saw at one corner of the bonded area. Begin sawing back and forth with moderate pressure, ensuring you pull on each end of the wire. This action will generate friction and start cutting through the adhesive.
Prop Open with Screwdrivers
Once you have sawed a few inches into the adhesive, it's time to introduce the screwdrivers. Insert one screwdriver at each end of the separated area, propping them open to prevent the adhesive from re-sticking due to the friction heat. Continue sawing, gradually moving the screwdrivers along as you go through more of the adhesive.
Scrape Away Residual Adhesive
After removing the majority of the adhesive with the wire saw, use a sharp chisel or similar tool to scrape away any remaining residue. If the adhesive is challenging to scrape off, you can apply a light layer of baby oil to soften it. However, avoid using oil or softening agents if you intend to paint the surface afterward as they can cause staining and contamination.
Removing No More Nails from concrete using a wire saw and screwdrivers requires patience and effort. Always prioritize your safety by wearing the appropriate protective gear and working in a well-ventilated area.

Use a grinder
Using a grinder is an effective way to remove nails from concrete. Grinders can be used to cut the nails or grind away the concrete around them. If you choose to cut the nails, a Dremel rotary tool or angle grinder with a cutting disc can be used. This method may chip the surrounding concrete, so it is important to wear safety glasses to protect your eyes from any flying debris. Alternatively, you can use a grinder to grind away the concrete around the nail until it is below the surface. This method will require patching the ground concrete to level the surface.
When using a grinder, it is important to take the necessary safety precautions. Grinding concrete can generate a lot of dust, so it is crucial to wear a respirator or mask to protect yourself from inhaling the dust. Safety goggles or a face shield will also help protect your eyes from any debris or sparks created by the grinder. It is also recommended to wear ear protection, such as earplugs or earmuffs, as grinding can be a noisy process.
Before using the grinder, ensure that you have read the instruction manual to familiarise yourself with the tool and its settings. Adjust the grinder to the appropriate height and angle for comfortable control during the process. Choose the right diamond shoe grit for your project. A lower grit is ideal for removing tough materials, while a higher grit will provide a polishing effect. Make sure the diamond shoe is securely installed and makes full contact with the concrete surface for even grinding.
Start by cleaning the floor and removing any small objects, such as nails, screws, or debris, that could interfere with the grinder. Evaluate the condition of the floor and fill any deep scratches, holes, or cracks with an epoxy filler before grinding. When you are ready to begin, grip the handle firmly and tilt the grinder slightly so that the diamond shoe is not in contact with the surface. Turn on the grinder and carefully lower it to the floor, beginning the grinding process. Work at a steady pace and take breaks as needed to avoid overheating the grinder.
Using a grinder is an effective method for removing nails from concrete, but it requires the right safety equipment and technique to ensure a successful and safe outcome.
