Finding the best picture hangers for plaster walls can be a tricky endeavor. With so many options on the market, it's important to consider a few key factors before making a purchase. First, assess the weight of the frames or art you'll be hanging. Heavy pieces require more reinforced hangers that can handle the load without pulling loose over time. Second, measure the thickness of your plaster walls and look for hangers specifically made for thin walls, usually around 1/2" thick or less. The right hanger will have long, sharp nails or molly bolts that can firmly grip the lath (wood or metal mesh) underneath the plaster.
Finally, think about ease of use. Do you want hangers that are simple to install into the wall with a hammer or self-drilling models that require less effort? There are also temporary options like removable adhesive hooks if you'll be changing art frequently. Taking the time to evaluate your specific needs will ensure you find the most suitable plaster wall hangers for displaying your beloved artwork or photographs in a secure and stylish way.
Some key questions to ask yourself are: How heavy are the frames I need to hang? How thick are my plaster walls? Do I want permanent or temporary hanging options? Do I prefer simple or self-installing hangers? Carefully considering these factors will lead you to make the right choice for safely securing your art to plaster walls.

2. Plaster Picture Hangers: Ez-Hang Kit
I purchased these hooks because I recently moved into a new home with plaster walls, which do not allow for the use of tacks.

Not only are these hooks easy to use, but they also do not require a drill. They are highly effective in keeping frames and stands secure. I typically buy them in packs of three or four at the hardware store, but I always seem to run out when I need them most.

They were easy to install on both drywall and pine lumber wall studs, which was the scenario in my case. The most challenging part of the process was determining the placement on the wall, but with the help of tools like a pencil, painter's tape, tape measure, and level, I was able to achieve precise positioning. I also appreciated that the hooks were compact in design while still being strong and reliable. I used a 10-ounce claw hammer to drive the nails, and I have complete confidence in their stability.

I used two hooks as the mirror had two hooks on the back, and they held up the mirror with ease. The installation process was super easy, requiring just a hammer. What I really appreciate about these hooks is that they hook upwards instead of using a nail that comes out perpendicular to the wall. This not only makes it easier to hang the mirror but also adds an extra level of strength and security.

After using the kit, I can confidently say that while the design of the hooks and nails is great, the assortment of hooks is a disappointment. The kit claims to have 125 pieces, but it actually only has a few hooks in each of three sizes for pictures between 10 and 30 pounds requiring one nail. On the other hand, it has an excessive supply of large hooks rated at 75 pounds requiring three nails. If you have a lot of very heavy pictures, this assortment might be suitable for you. However, if most of what you have to hang are less than 75 pounds, this particular assortment would be a waste of money.

However, this turned out to be a pleasant surprise as I had extras for future use.

8. Easyhangs 30lbs – 25pk – Picture Perfect Solution
I recently tried these picture hangers and I must say, they exceeded my expectations. After reading some negative reviews, I was initially hesitant, but upon carefully reading and understanding the instructions, I realized that many of the issues people had were due to not following the instructions properly.
The most important thing to note is that the nails for these picture hangers should not be aggressively hammered into the wall. Instead, they should be tapped lightly with a hammer. This tapping motion may require a bit more patience, as it might take around 150 to 175 taps for the nail to securely go into the plaster wall. However, this method ensures that the hangers are properly and securely in place. I also found that using a piece of tape helped prevent any damage to the wall during the process.
Interestingly, as someone with a background in museum prep work, I was delighted to find that these picture hangers are the same ones used for framed works of art in professional settings. This gave me even more confidence in their quality and reliability.

While the package may seem more expensive per item, it's important to consider whether you will actually use all the hooks included.
Are there any alternative methods or products for hanging pictures on plaster walls that are worth considering?
Yes, there are alternative methods and products for hanging pictures on plaster walls that are worth considering. One option is to use adhesive hooks specifically designed for plaster walls. These hooks have a strong adhesive backing that can securely hold lightweight to medium-weight pictures without the need for drilling or damaging the wall.
Another alternative is to use picture hanging strips. These strips have a sticky surface on both ends, allowing you to attach one end to the wall and the other to the back of the picture. They provide a secure hold and can be easily removed without leaving any residue or causing damage to the plaster.
Additionally, you can consider using picture rail systems, which involve installing a rail along the top of the wall and using hooks or wires to hang the pictures. This allows for easy rearrangement and flexibility in displaying your artwork.
It's always recommended to follow the instructions provided by the manufacturers of these alternative methods or products to ensure proper installation and avoid any potential damage.
Are there any special considerations or precautions I should take when hanging pictures on old or fragile plaster walls?
When hanging pictures on old or fragile plaster walls, there are a few special considerations and precautions you should take to ensure the safety of the walls and the artwork. Firstly, it is important to locate the studs or beams behind the plaster to provide adequate support for the hanging.
You can use a stud finder to locate these points. Once you have found the studs, use appropriate hardware such as picture hooks or wall anchors that are designed for plaster walls. Avoid using nails directly into the plaster as it may cause damage.
Additionally, if the plaster is particularly fragile, you may want to consider using adhesive hooks or picture hanging strips that do not require any drilling or nailing into the wall. These options provide a more temporary and less invasive solution.
Always be mindful of the weight of the artwork and choose appropriate hardware that can support the load.
If you are unsure about the condition of the plaster or the best method to hang your pictures, it is recommended to consult with a professional handyman or a local art gallery for further guidance. They can assess the condition of the walls and provide specific recommendations based on their expertise.
Are there any specific techniques or tools I should use when installing picture hangers on plaster walls?
When installing picture hangers on plaster walls, there are a few techniques and tools that can make the process easier and more effective. Firstly, it is recommended to use a stud finder to locate the wooden studs behind the plaster. This will provide a secure anchor point for your hanger.
Once the stud is located, you can use a pencil to mark its position.
Next, it is important to choose the right type of hanger for your picture. Plaster walls can be more fragile than other wall materials, so it is advisable to use hangers specifically designed for plaster. These hangers often have wide, flat hooks that distribute the weight of the picture more evenly.
To install the hanger, use a drill with a small drill bit to create a pilot hole at the marked position. This will prevent the plaster from cracking or chipping. Then, insert a screw with the appropriate size into the pilot hole and tighten it until it is secure.
If you are hanging a larger or heavier picture, it may be beneficial to use multiple hangers evenly spaced along the wall for added support.
Overall, using a stud finder, choosing the right hanger, and properly securing it with a pilot hole and screw are important techniques to ensure a successful installation on plaster walls.
Can I use adhesive picture hangers on plaster walls, or are there better alternatives?
Yes, you can use adhesive picture hangers on plaster walls. Adhesive hangers are a popular choice for hanging lightweight items on plaster walls as they eliminate the need for drilling holes. However, it is important to ensure that the adhesive hangers you choose are specifically designed for use on plaster walls.
Plaster walls can be more delicate than drywall, so using the right adhesive hangers will help prevent damage to the plaster.
If you prefer an alternative to adhesive hangers, there are a few options available. One option is to use hooks that are designed to be inserted into the plaster. These hooks provide a secure hold and can be easily removed without causing damage to the wall.
Another alternative is to use picture rail molding, which is a decorative molding installed near the ceiling that allows you to hang artwork using wire and hooks. This option is particularly popular in older homes with plaster walls.
Ultimately, the choice of which method to use depends on your personal preference and the weight of the items you wish to hang. It is always a good idea to consult with a professional or do some research to ensure you are using the best method for your specific situation.
Can I use nails to hang pictures on plaster walls, or should I use a different type of hanger?
Yes, you can use nails to hang pictures on plaster walls, but it is important to use the right type of nail and take certain precautions. Plaster walls are more delicate compared to drywall, so using the correct hardware is crucial to avoid damaging the wall.
Instead of regular nails, it is recommended to use picture hooks or masonry nails specifically designed for plaster walls. These types of nails have larger heads and provide better support for hanging pictures.
Pre-drilling a small hole in the plaster before inserting the nail can also help prevent cracking.
If you have particularly heavy or valuable artwork, it may be wise to consider using wall anchors or toggle bolts. These provide extra stability and can support heavier weights. It's always a good idea to check the weight limit of the hardware you're using and ensure it can support the weight of your picture.
If you're unsure about the integrity of your plaster walls or want to avoid any potential damage, using adhesive hooks or removable hanging strips can be a suitable alternative. These options are easy to install and remove without leaving any marks or holes on the wall.
In any case, it's advisable to test the hanging method on a less visible area of the wall before committing to hanging your pictures.
How do I choose the right size picture hangers for my plaster walls?
When choosing the right size picture hangers for plaster walls, there are a few factors to consider.
Firstly, you need to determine the weight of the picture or artwork you want to hang. This can be done by using a scale or referring to the product's specifications.
Next, it's important to understand the type of plaster wall you have. Plaster walls can vary in thickness and strength, so it's essential to choose hangers that can support the weight without damaging the wall.
Once you have this information, you can select the appropriate size of picture hanger. It's recommended to choose hangers that have a weight capacity slightly higher than the weight of your artwork to ensure stability and safety.
Additionally, consider using hangers specifically designed for plaster walls, as they often have features like wider hooks or adjustable brackets that provide better support.
If you're unsure about the weight or the type of plaster wall you have, it may be helpful to consult with a professional or seek advice from a local hardware store. They can provide you with specific recommendations based on your needs.
How do I find the stud or secure spot in a plaster wall to hang my pictures?
To find a stud or secure spot in a plaster wall to hang your pictures, you can follow these steps:
1. Use a stud finder: Invest in a good quality stud finder, which is a handheld device that helps detect studs behind the wall. Follow the instructions provided with the stud finder to calibrate it correctly. Slowly move the stud finder across the wall until it indicates the presence of a stud.
2. Look for visual cues: In older homes, studs are often placed at regular intervals, typically 16 or 24 inches apart. Look for any visible signs, such as nail heads or seams in the plaster, which can indicate the presence of a stud.
3. Tap the wall: Gently tap the wall with your knuckles or a small hammer. A hollow sound indicates an empty space, while a solid thud suggests the presence of a stud.
4. Measure from known reference points: If you have a door or window frame nearby, measure the distance from the edge of the frame to find the stud. Studs are usually placed around 16 inches apart, so you can use this measurement to locate other studs.
5. Trial and error: If all else fails, you can use a small nail or drill bit to make small holes in the wall until you hit a stud. Once you find a stud, you can use it as a reference point for hanging your pictures.
Remember to use appropriate hardware, such as screws or anchors, to securely hang your pictures on the stud or secure spot.
What are some tips for hanging heavy pictures on plaster walls without damaging them?
When it comes to hanging heavy pictures on plaster walls without damaging them, there are a few tips to keep in mind:
1. Locate a stud: Plaster walls are more fragile compared to drywall, so it's important to find a stud for added support. Use a stud finder to locate the wooden framing behind the plaster.
2. Use appropriate hardware: Invest in heavy-duty picture hanging hardware such as wall anchors or toggle bolts that are designed to support the weight of your artwork. Avoid using nails or regular screws that can easily pull out of plaster.
3. Pre-drill pilot holes: Before inserting any hardware, pre-drill pilot holes using a drill bit slightly smaller than the size of the screws or wall anchors. This helps prevent the plaster from cracking or crumbling.
4. Distribute weight evenly: For larger or heavier pictures, consider using multiple hooks or hanging systems to distribute the weight evenly across the wall. This reduces the strain on a single area of the plaster.
5. Avoid hanging on weak spots: Identify areas of the wall that may be weaker, such as near windows or door frames. It's best to avoid these areas and look for stronger sections of the wall or use alternative hanging methods like using a picture rail or adhesive hooks.
Remember to always follow the manufacturer's instructions for the specific hanging hardware you choose, and if you're unsure about your abilities, seek assistance from a professional handyman or a hanging service.
What are the best types of picture hangers for plaster walls?
When it comes to hanging pictures on plaster walls, there are a few types of picture hangers that work well. One popular option is using picture hooks with nails. These hooks have a sharp point that allows them to penetrate the plaster easily.
They come in various sizes and weight capacities, so you can choose the right one based on the weight of your picture.
Another option is adhesive picture hangers. These hangers use strong adhesive to stick to the wall, eliminating the need for nails. They are easy to install and remove without causing damage to the plaster. However, it's important to check the weight limit of the adhesive hanger before using it.
If you have a particularly heavy picture, it may be best to use a combination of hardware. This can include using a picture hook with a wall anchor or using a wall anchor with screws. Wall anchors provide extra support and help distribute the weight more evenly, reducing the risk of damage to the plaster.
Ultimately, the best type of picture hanger for plaster walls will depend on the weight and size of your picture. It's also a good idea to consider consulting a hardware store or a professional for specific recommendations based on your needs.
What are the common mistakes to avoid when hanging pictures on plaster walls?
When hanging pictures on plaster walls, there are several common mistakes to avoid in order to ensure a secure and damage-free installation. Firstly, avoid using regular nails as they can easily crack the plaster. Instead, opt for picture hooks or anchors specifically designed for plaster walls.
These provide better support and distribute the weight more evenly.
Another mistake to avoid is not locating the studs or using wall anchors incorrectly. It's important to find the studs behind the plaster to provide a sturdy anchor point for heavier pictures. If studs are not available in the desired location, use wall anchors designed for plaster walls to ensure a secure hold.
Additionally, failing to use a level when hanging pictures can result in a crooked display. Take the time to measure and mark the desired location, and use a level to ensure the picture is straight.
Lastly, avoid hanging pictures in high-humidity areas, such as bathrooms, where moisture can weaken the plaster and compromise the integrity of the installation. If necessary, consider using moisture-resistant picture hanging hardware or alternative display options such as adhesive hooks.
By avoiding these common mistakes, you can ensure a successful and long-lasting picture hanging experience on plaster walls.
