While they rarely affect the structure of your walls, they can be a sign of a deeper foundation problem. Luckily, they are easy to fix and you can achieve perfectly smooth walls.

What You'll Learn
Identify the cause of nail pops
Nail pops are caused by the wood underneath shifting around. This movement is caused by fluctuations in humidity and temperature. When the wood dries out, it warps and changes, causing the wood fibres to lose their grip on the nail, and the nail pops through the drywall. This is more likely to happen with older homes where large roofing nails were used to secure drywall instead of modern drywall screws. Roofing nails have a smooth surface and don't grip into the wood effectively.
In newer homes, nail pops can be caused by the outside weather in combination with the well-sealed and insulated nature of modern homes. Changes in humidity can also cause the wood to expand and contract, leading to nail pops.
Nail pops can also be caused by the wooden roof decking being too worn down or rotted to support the nails. In some cases, the nails used during installation may be too short to correctly anchor the shingle to the roof's wooden underlayment, causing the nail to rise over time.
While nail pops are usually a cosmetic issue, they can sometimes point to deeper structural problems. If you start seeing them everywhere, it may be a good idea to contact a foundation expert.

How to fix nail pops in drywall
Nail pops are small, circular bulges that appear on walls and ceilings when nails slowly work their way out of drywall. While they rarely affect a wall's structure, they can be unsightly and ruin the uniform look of a wall.
To fix nail pops in drywall, start by inspecting the area and lightly sanding it with fine-grit sandpaper. If the nail is just a little loose, knock it back in with a hammer, taking care not to damage the drywall more than necessary. Then, install a drywall screw next to it, one inch above or below the nail. You can also remove the nail entirely and replace it with a screw. These screws essentially replace the original nail or screw, providing more security to the frame so that the nail pop doesn't happen again.
After securing the nail or screw, apply a coat of joint compound, also known as "hot mud," to the area and smooth it out. Allow the compound to dry, and then sand it down to ensure it is even with the wall. Once you're satisfied with the smoothness of the area, you can prime and paint over it to match the rest of the wall.
While fixing individual nail pops is a simple process, if entire rooms have many nail pops, it may indicate a deeper structural problem. In such cases, it is recommended to contact a foundation expert or a drywall contractor to assess the issue and determine if the drywall needs to be replaced.

When to call a foundation expert
Nail pops are usually cosmetic issues that can be easily fixed. They are caused by short nails that are no longer firmly attached to the studs, and they rarely affect your wall's structure. However, in some cases, they can indicate a more serious problem with your home's foundation.
If you notice a large number of nail pops or if they are appearing all over your house, it is a good idea to contact a foundation expert to assess the situation properly. Nail pops can be an indication of foundation settlement, which occurs when the soil surrounding your home expands due to too much moisture or contracts due to too little moisture. This expansion and contraction cause the soil to shift, affecting your foundation's structural integrity.
Additionally, if you notice any visible faults in the foundation itself, such as cracks or water damage, it is best to call a contractor. Other signs of foundation problems include sticking windows and doors, which can indicate that your house is sinking or becoming tilted due to foundation issues.
While it is uncommon for nail pops to indicate a serious problem, it is important to take them seriously at the first sighting. Foundation issues can lead to more expensive repairs if left unaddressed. Therefore, if you suspect any issues with your foundation, it is recommended to call a foundation repair expert for a free inspection and evaluation.
In summary, while nail pops are typically cosmetic and easy to fix, they can sometimes indicate a larger issue with your home's foundation. If you notice a significant number of nail pops, observe them throughout your house, or see any other signs of foundation problems, it is essential to contact a foundation expert for a proper assessment and to prevent further damage.

Patching and painting over nail pops
Nail pops are a common issue in drywall ceilings and interior walls, causing small circular bulges that protrude from the surface. While they rarely affect the structure of your wall, they can ruin the uniform look of your walls and cause paint to crack.
To fix nail pops, start by inspecting the area and scraping away any excess drywall from the nail or screw head. If it's a screw, use a screw gun to loosen it, then screw it back into the wood frame. If it's a nail, hammer it back into place without damaging the drywall. To prevent the nail pop from recurring, add screws one inch above and below the original screw or nail.
Once you've secured the nail or screw, it's time to patch the holes. Use a patching tool to scoop up some patching material and cover the holes. Smooth out the material and let it dry. After it's dry, sand the patched area with fine-grit sandpaper to ensure it's even with the wall.
Now you can prime and paint the patched area. It's recommended to use a drywall sealer or primer on the patched spots before painting, especially if you used joint compound or spackle for patching. You may need to apply a second coat of paint to ensure the patch is no longer visible.
By following these steps, you can effectively fix nail pops and achieve a flawlessly smooth wall surface that's ready for painting.

Using screws vs. nails
Nail pops are a common issue in drywall, caused by the expansion and contraction of the wood frame behind it. While they are usually a cosmetic problem, they can sometimes indicate a deeper structural issue.
When addressing nail pops, you can use either screws or nails to fix them. If you use a nail, simply hammer it back into place, being careful not to damage the drywall. However, this method may not be very effective, as the nail can work its way back out over time.
Using screws to fix nail pops is a more secure method. First, loosen the popped screw with a screw gun and screw it back into the wood frame to level it. If it is a nail, you can hammer it back into place and then add screws one inch above and below the original nail or screw. This provides additional support to the frame and reduces the likelihood of the nail pop recurring.
It is recommended to use drywall screws instead of nails when hanging drywall. Screws are less likely to pop out than nails and provide a stronger hold. They are also easier to remove if necessary. However, some people prefer to use nails because they are faster and easier to install.
When addressing nail pops, it is important to consider the spacing of the screws or nails. They should be spaced no more than one foot apart when attaching drywall to a ceiling. Closer spacing reduces the chances of nail pops and does not significantly increase building costs. Additionally, when hanging drywall, it is recommended to use a fastener, preferably a screw, every eight inches along the edges and every 12 to 16 inches in the center of the panel over each stud.

Frequently asked questions
Nail pops are small, circular bulges on walls and ceilings, caused by nails that have slowly worked their way out.
Nail pops occur when the wood framing expands and contracts due to changes in humidity and seasons, causing the wood to lose its grip on the nail.
Nail pops are typically not a major issue and are usually cosmetic imperfections. However, in some cases, they may indicate a deeper structural problem, especially if they are widespread.
To fix nail pops, you can tap the nail back in with a hammer and then secure it with drywall screws. Screws should be placed one inch above and below the nail to attach the drywall securely to the stud. After securing the nail, you can apply a coat of joint compound or "hot mud" to fill in any remaining holes.
It is not recommended to paint over nail pops without fixing them first. Left unrepaired, the nail pops will still be visible after painting, and the paint may crack as the nail pops continue to protrude.
