Filling cracks in plaster walls can seem like a daunting task, but with the right filler and technique, it doesn't have to be. When choosing a filler, you'll want to consider factors like the size and depth of the crack, the location, and the finish you want to achieve. Small hairline cracks can often be filled with lightweight spackling compound. For larger cracks or those in high movement areas like corners, a more flexible filler like painter's caulk is a better choice. For deep cracks wider than 1/8 inch, you may need a setting-type compound.
Before starting, make sure to clean out loose plaster and debris so the filler can adhere. When applying the filler, press it deeply into the crack to prevent shrinking and cracking later on. Smooth with a putty knife for the best finish. Once dry, sand if needed before painting. With some basic prep and the right filler for your specific cracking situation, you can achieve smooth, seamless walls once again.
Thinking of filling cracks in your home's plaster walls? What type of cracking do you need to repair? Are your walls prone to cracking again in the same spots? Considering factors like these will help you choose the ideal filler to permanently patch plaster cracks for good.

1. Saint-Gobain Adfors Fdw9098-U Fix It Fast Wall Hole Filler, White, 3 Ounce
I recently purchased this amazing wall repair product and I must say, it exceeded my expectations. As someone who is not particularly handy, I often find myself in need of a solution to fix holes in my walls caused by constantly moving pictures around. This product has been a game-changer for me.
The first thing that impressed me was how seamlessly this wall repair putty blended into the paint on my walls. It matched the color almost perfectly, making the repaired areas virtually invisible. Not only was it quick and easy to use, but it can also be resealed for future use, which is a great bonus.
For someone like me who enjoys decorating but lacks the skills to handle wall repairs, this product has been a godsend. In just 15 minutes, I was able to fix all the holes around my house and I couldn't be happier with the results. It's truly the best $5 I've ever spent and I will definitely be purchasing more.
I also used this wall repair putty to cover smaller holes and missing paint chips from a previous wall setup. It was incredibly easy to work with and the drying time was reasonable, taking about a day. I even went a step further and sanded and painted over the repaired areas to make them even more flush with the wall. The end result is so seamless that you can hardly tell there was any previous damage.
What impresses me the most about this product is its ability to thoroughly cover and blend with the walls. Even after a few hours, I couldn't see any trace of the filled holes. It's like they never existed. I had four holes under a black frame and between the leaves in one of my pictures, and this product worked like magic.
It's worth mentioning that this wall repair putty works best with true white walls. Mine has a slightly grey undertone, so the putty does stand out a bit. However, it still does a great job of filling and blending in. If you have white walls, this product will blend in perfectly.
I also used this product to fill nail holes in my classroom, and I was pleasantly surprised by the results. I was worried that the white filler would be noticeable on my off-white walls, but fortunately, the filler itself is slightly off-white as well. The putty spreader included with the product was easy to use, and I was amazed at how the nail holes became barely visible with just a small amount of product. I wish I had taken before and after photos to showcase the results.
2. Quickfix Wall Patch Kit
I recently had to repair some damaged walls in my living room and came across this amazing mending agent. I had created a music wall with various instruments hung up, but it ended up causing quite a bit of damage due to the screws I had to drill in. I was particularly worried about the larger holes left behind by a bicycle rack used to hang a didgeridoo.
In the past, I have used ordinary spackle, but it can be difficult to work with, especially when trying to fill small holes. Additionally, it tends to leave air pockets, and the cleanup process can be quite tedious. I also dislike how it comes in tubs, as it can easily dry out if not closed properly, but can be challenging to reopen when sealed tightly.
However, this mending agent proved to be a game-changer. I was initially skeptical due to its liquidy consistency, but it surprised me with its effectiveness. While it didn't provide a perfect result on the largest holes after just one coat, the provided spatula tools made it easy to reapply the mending agent and achieve the desired outcome. I did notice that it tended to sink down and become concave within an hour, but this was easily rectified by scraping off the excess and reapplying a bit more.
After allowing it to dry for the recommended 4 hours (I opted to wait 24 hours), sanding down the repaired areas was a breeze. Everything turned out completely flat, ready for a few coats of paint to make the wall look as good as new. The ease of use and the flawless end result made this mending agent a winner in my book.
What impressed me even more was its versatility. It worked wonders on both small nicks and larger dents. Even scraped up corners with missing bits of sheetrock were easily repaired using this product. The included spatula was incredibly handy for smoothing out the mending agent, and once sanded down, the repaired areas blended seamlessly with the rest of the wall.
I am thrilled with the results and plan on using the remaining mending agent for other repair projects in our rental properties. It has earned its place among my essential tools. If you're in need of a reliable and user-friendly solution for wall repairs, I highly recommend giving this mending agent a try.
3. Quickpatch: Easy Wall Repair Kit For Diyers
The drywall repair kit exceeded my expectations in terms of ease of use and effectiveness. I had a hole in my drywall that needed fixing, and this kit saved me a significant amount of money compared to hiring a professional. The wall mending agent included in the kit did an exceptional job of filling in cracks and holes, leaving the surface smooth and flawless.
I was particularly impressed with the scraper and sandpaper provided in the kit. They made it incredibly easy to achieve a professional-looking finish. Additionally, the disposable gloves included in the kit were a thoughtful addition, ensuring cleanliness throughout the repair process.
One feature that stood out to me was the nozzle extenders. These extenders proved to be a lifesaver when it came to reaching those tricky and hard-to-access areas on the wall. They allowed me to apply the wall mending agent precisely and efficiently.
The squeeze tube design of the product made it effortless to apply the wall mending agent, and the sandpaper and small squeegee provided helped me achieve a smooth finish. The overall result was impressive, with my walls looking as good as new after the repair.
I highly recommend this product to anyone in need of a quick and professional solution for wall repairs. It not only saved me money but also delivered exceptional results. Whether you have cracks, holes, or any other damage on your walls, this drywall repair kit is a reliable and easy-to-use option.
4. Gorilla Heavy Duty Wall Repair Spackling + Primer, 16 Ounce Tub,white
I recently had a small drywall repair job that needed to be done on a tight budget, and I stumbled upon the Gorilla Heavy Duty Wall Repair Spackling + Primer. Let me tell you, this product exceeded my expectations.
First of all, the repair kit is perfect for small to medium drywall repairs. I had a rather large hole in my wall caused by a torn toilet paper holder, and this kit did the trick in repairing, sanding, and blending the hole seamlessly with the rest of the wall. I haven't painted it yet, but I have no doubt that it will blend in perfectly.
The application of the product was incredibly easy. Even though my walls are textured, you can't tell there was a hole after using this spackling. I would recommend getting a can of texture wall spray if you have a textured wall to ensure a seamless blend. The adhesive in the kit is decent, but not the stickiest, so be careful not to pull the patch off while applying it.
I found the product to be of great quality, and it hardened much better than other spackling products I've tried in the past. This Gorilla product was worth every penny and truly delivered on its promises.
I also want to mention that the generously sized 16-ounce tub of spackling and primer will come in handy for larger repair jobs. I'm currently demo-ing a large bathroom with lots of things attached to the wall, and I know this product will speed up the repairs and ensure a professional finish.
5. 3m High Strength Small Hole Repair, All In One Applicator Tool
I rarely write reviews, but I have to say, this product is truly amazing! As someone who has zero handy experience, I was pleasantly surprised by how easy it was to use. I recently moved out of my apartment in NYC (a nightmare in itself), and I needed to fill some holes I made with wall anchors. This product made the process a breeze.
I do agree with other reviewers that using real sandpaper is essential if you want flawless walls. However, even with minimal effort on my part, the results were pretty good considering my old apartment. If you take the time to paint over the patched areas (which I didn't), it will look as good as new. It's a dream come true for renters.
A little goes a long way with this product. I'm only halfway through the tube, and I've used it multiple times over the past year. It works wonders for smaller holes from hanging pictures and deeper ones from adjusting closet racks with nail brackets. I even used it to patch a hole that was slightly off from where I needed to hang a heavy painting. I filled it with the spatula end, let it dry for 3 days (just to be safe), and then drilled in the same spot. The patch was completely dry, with no gunk in the middle.
The sander that comes with the product is easy to clean off and still maintains decent grit after many uses. I'm usually skeptical of buying products based on influencer recommendations, but this one is a must-have for any renter or homeowner.
Now, regarding the cancer warning: If you use this product daily for your work, especially by the tub, then yes, you need to take precautions as it can be toxic. However, using it for small nail holes in your hallway will not cause cancer. Most schools still have asbestos in them, and as long as it's left undisturbed, it's fine. The product works as intended, and I have provided pictures as proof.
I can't speak highly enough of this product! Initially, I bought it to fill regular nail holes in the wall before moving out of our house. However, I was pleasantly surprised when it also filled in deep gouges left by my cat's claws. Some of these gouges were down to the metal on the corner, but after sanding and painting, you can't even tell they were there. The only downside is that the firm bottle is difficult to squeeze, unlike a soft toothpaste tube. This made it challenging to retrieve the product after using the first half. Nonetheless, I've already purchased another one to finish patching holes in other rooms and fixing dings here and there.
6. Patchpro: Quick Wall Repair Kit – Fix Holes Fast!
Hide A Hole is an impressive product that offers all the necessary tools and materials for wall repairs. It provides a convenient and hassle-free cleanup process. The overall experience of using Hide A Hole was satisfying, although it did take about 25 minutes to complete the repair due to the screwdriver being a little small for larger hands. However, switching to a larger Phillips screwdriver significantly sped up the process.
The patch created by Hide A Hole is remarkably strong and looks as if a professional had done it. This aspect of the product left me feeling extremely pleased with the results. I would highly recommend Hide A Hole to others and would definitely purchase it again for future repairs.
My wife and I were particularly delighted with Hide A Hole when our grandkids accidentally put a hole in the wall. We found this product on Amazon, and it worked perfectly for us. It is truly a great invention that saved us from the inconvenience and expense of hiring a professional.
This set is specifically designed for medium-sized holes, rather than smaller nail holes. If you are familiar with patching walls, you may find it slightly awkward to use. However, it does provide a solid repair and is undeniably easier than trimming and replacing an entire section between the studs.
Hide A Hole is a one-time kit for repairing holes that are too large for mesh but where cutting and mudding in a separate piece of drywall is not desired. The kit includes a circular stencil for cutting the drywall around the hole, a double-sided drywall knife, a plastic "mesh" (designed solely for making a circular repair hole of approximately 6.5 to 6.75 inches in diameter), back braces, two tubes of mud, a thin plastic trowel, drywall screws, a small screwdriver, and a sanding block for finishing work.
The process involves cutting a deliberate round hole around the damaged area using the provided stencil, removing the cut-out section with the knife, and then securing the back braces into the resulting gap using the screws. The circular plastic mesh is then screwed into the back braces, followed by mudding and finishing the repair. The company's website features a helpful video demonstrating the process.
For those who are new to repairing or working with drywall, the instructional video is a valuable resource. The video provides important tips, such as saving the circular piece cut out for color matching at Home Depot and properly sinking the screws. However, the video does not cover the proper application and smoothing techniques for the mud or filling in the screw heads. Additional videos on platforms like YouTube may be necessary for those seeking guidance on these finishing aspects.
Although I have not yet had the opportunity to use the kit for an actual repair, I did test one of the tubes of mud to fill a couple of nail holes, and it worked perfectly fine. The color matched most standard white walls, and only a small amount was needed. The consistency of the mud is slightly different from the typical spackle, being thinner and easier to spread, which is advantageous.
I appreciate the fact that the drywall knife included in the kit comes to a point, as it offers better functionality compared to the handsaw-like knife I usually use. Additionally, the inclusion of drywall screws specifically designed for this kit is a thoughtful touch.
To sum up, Hide A Hole is an excellent solution for those who have never repaired a hole before. By watching the instructional video and taking your time, you should be able to successfully patch the hole you intended to fix. For experienced repair individuals, the video will provide insight into whether this kit suits their specific circumstances.
Lastly, I must address an outdated comment on the company's homepage regarding "filling in the holes your wife made to hang her decor." As the wife myself, I want to clarify that I am fully capable of performing drywall repairs, taping, mudding, and finishing. This comment is unnecessary and perpetuates outdated stereotypes.
7. 3m High Strength Large Hole Repair, Fiber Reinforced Spackling Compound, 32 Oz.
I recently purchased the 3M Patch Plus Primer Kit for a phone mount installation and I must say, it exceeded my expectations. As someone with no experience in drywall, I was initially overwhelmed by the prospect of wire mesh and tape. However, this kit made the process incredibly easy.
First and foremost, the kit emphasizes the importance of a clean and dust-free surface. Although my walls weren't perfect due to insulation and other factors, I was able to clean them as best as I could. I also used a razor to trim any ragged edges. The 3M backpiece adhered effortlessly and could be easily adjusted by breaking off pieces to fit the size of my hole, which was against a stud on one side.
Next, I filled the hole with the provided filler, and let me tell you, this stuff is amazing! Unlike basic spackle, it was incredibly easy to work with and fill the entire hole. The tip about wetting the putty knife for a final pass was a game-changer, making the process quick and efficient. I only ended up using about half of the container and had plenty left over to fill other small holes and dings around my house.
The filler dried remarkably fast, and the next day, sanding it down to a smooth finish was a breeze. I should note that my patch was going behind a backsplash, so texture wasn't a concern for me. However, if you're looking to match a textured wall, you would need to purchase a separate texture kit, as this product leaves a smooth finish.
I did come across some reviews mentioning that the adhesive tape on two sides was just okay, so I took the precaution of ordering a bottle of clear Gorilla Glue. I applied a medium strip of glue down the middle of the tape on those sides, and instead of pulling the tape and holding it, I used something to loop through the handle and tightened it until the patch was firmly pressed against the wall. I left it overnight, and the next morning, the patch was perfectly sealed.
One other thing worth mentioning is that the putty doesn't shrink as it dries, which is a great bonus.
8. Red Devil 1226 Onetime Fiber Mesh Crack Patch 6" X 75' Wall Repair Fabric, 1-Pack, White
I recently purchased the Red Devil Fiber Mesh for repairing the cracked plaster ceilings in my 1940s house. I found this product to be incredibly easy to work with. After cleaning the areas around the cracks, the Fiber Mesh adhered well to the textured ceiling. I did need to apply a second or even third coat due to the texture and previous attempts at repairs, but overall, the Fiber Mesh stayed in place even after leaving it alone for over a week. I highly recommend the Red Devil Fiber Mesh for anyone facing a similar situation.
In addition to using it for ceiling repairs, I also used the Red Devil Fiber Mesh to patch holes in my walls. While it could have had better stickiness, especially for a first-time patching job, it still worked well. There was a little bit of movement, but once I applied the spackle, there were no issues. This product was especially useful for covering larger holes and allowing them to be seamlessly covered with spackle. I definitely recommend giving it a try.
On a lighter note, I must admit that I used the Red Devil Fiber Mesh to rebuild a wall using patches without my wife's knowledge. She'll find me guilty for this cheeky act! But in all seriousness, the Red Devil Fiber Mesh served its purpose and successfully fixed my wall. The adhesive may not be the strongest, but when used with putty, it works just fine.

The QuickFill nail hole repair kit is a game-changer when it comes to patching up walls. It eliminates the hassle of filling nail holes and waiting for layers of spackle to dry. With this product, you can say goodbye to shrinking and uneven drying.
One of the standout features of this product is its built-in spackle knife, which makes the entire process a breeze. You can easily fill in the holes and even use it cosmetically to make a portion of the wall more even. The result is a smooth finish that requires minimal sanding. In fact, you won't be able to tell where the drill holes used to be on the wall.
The customer service provided by the company is also commendable. In a situation where USPS mishandled an order, the company was extremely responsive and sent a no-cost replacement promptly. They even followed up with the customer throughout the entire process, ensuring a positive experience.
For those living in apartments or anyone who may not have experience with wall repairs, this QuickFill kit is a must-have. It simplifies the process and makes it easy to repair small holes in drywall. Whether you're a renter or a homeowner, having a product like this on hand can save you time and frustration.

It fills holes and other defects in drywall with precision, requiring only one application. It's a versatile tool that anyone can use, not just handymen.
The ease of pushing the material into damaged holes, whether it's a large screw hole or a small thumbtack hole, is impressive. The fact that it dries white and is easy to install and store further adds to its convenience.
Are there any special techniques for applying filler to cracks in textured plaster walls?
Yes, there are some special techniques for applying filler to cracks in textured plaster walls. Here are a few steps you can follow:
1. Clean the area: Before applying any filler, make sure to clean the cracked area thoroughly. Remove any loose plaster, dirt, or debris from the crack using a brush or vacuum cleaner.
2. Prepare the filler: Use a high-quality filler that is suitable for plaster walls. Mix the filler according to the manufacturer's instructions until you achieve a smooth consistency.
3. Apply the filler: Using a putty knife, carefully apply the filler into the crack, ensuring it fills the entire depth of the crack. Smooth the filler over the crack using the putty knife, feathering the edges to blend with the surrounding texture.
4. Texturing: To match the existing texture of the plaster wall, you can use various techniques. One option is to use a textured roller or brush to recreate the texture. Another option is to mix some sand or fine-textured material with the filler before applying it to the crack.
5. Sand and finish: Once the filler has dried, use sandpaper to smooth out any rough edges or excess filler. Make sure the repaired area blends seamlessly with the surrounding texture. Clean the area again to remove any dust.
Remember to follow all safety guidelines and use appropriate protective gear when working with fillers and textured plaster walls. If you are unsure about the process, it's always a good idea to consult a professional for guidance.
Can I paint over the filler used to repair cracks in plaster walls?
Yes, you can paint over the filler used to repair cracks in plaster walls. However, it is important to ensure that the filler has fully dried and hardened before applying paint. Typically, this can take anywhere from a few hours to a day, depending on the type of filler used and the depth of the crack.
Once the filler is completely dry, you can lightly sand it to smoothen the surface and remove any excess filler. Afterward, you can apply a coat of primer to ensure better adhesion of the paint. Finally, you can paint over the repaired area, making sure to blend it seamlessly with the surrounding wall.
It's always a good idea to consult the manufacturer's instructions for both the filler and paint to ensure compatibility and the best results.
Can I use spackling paste as a filler for cracks in plaster walls?
Yes, spackling paste can be used as a filler for cracks in plaster walls. Spackling paste is a versatile material commonly used for patching and repairing minor imperfections in walls, such as cracks, holes, or dents.
It is typically made from a combination of gypsum, binders, and additives, which give it a smooth texture and allow it to adhere well to various surfaces, including plaster.
To use spackling paste for cracks in plaster walls, you will first need to clean the area around the crack and remove any loose debris or chipped plaster. Then, using a putty knife or a similar tool, apply the spackling paste evenly over the crack, making sure to fill it completely.
Allow the paste to dry according to the manufacturer's instructions, and then sand it down gently to achieve a smooth finish. Finally, you can paint over the patched area to match the surrounding wall.
However, it's important to note that spackling paste is best suited for small cracks and minor repairs. If you have larger or more extensive cracks in your plaster walls, it may be necessary to consult a professional or consider using a more specialized filler, such as joint compound or plaster of Paris, to ensure a proper and durable repair.
How do I prepare the crack in a plaster wall before applying filler?
Before applying filler to a crack in a plaster wall, it is important to properly prepare the area to ensure a successful repair. Here are the steps you can follow:
1. Clean the crack: Start by removing any loose plaster or debris from the crack. Use a utility knife or a scraper to gently scrape away any loose material. Be careful not to widen the crack while doing this.
2. Sand the edges: Next, use a fine-grit sandpaper to lightly sand the edges of the crack. This will help create a smooth surface for the filler to adhere to.
3. Apply a bonding agent: To enhance adhesion, it is recommended to apply a bonding agent to the crack. This can be a specific plaster bonding agent or a diluted PVA adhesive. Follow the instructions provided by the manufacturer for the application.
4. Fill the crack: Once the bonding agent has dried, it's time to fill the crack with plaster filler. Use a putty knife or a trowel to carefully apply the filler into the crack, ensuring it is completely filled and leveled with the surrounding surface.
Smooth out any excess filler and let it dry according to the manufacturer's instructions.
5. Sand and finish: After the filler has dried, use sandpaper to gently sand the filled area until it is smooth and flush with the wall. You can then proceed with painting or applying a suitable finish to match the surrounding wall.
Remember, if you are unsure about any step or lack experience, it is recommended to seek professional assistance to ensure a proper and long-lasting repair.
How long does it take for filler to dry in plaster walls?
The drying time for filler in plaster walls can vary depending on several factors. Typically, it takes around 24 to 48 hours for filler to fully dry and cure. However, this can be influenced by factors such as the thickness of the filler application, humidity levels, and temperature conditions.
Thinner layers of filler will dry more quickly compared to thicker applications. It's important to allow enough time for the filler to dry completely before sanding or painting the surface. Rushing this process may result in a compromised finish.
To speed up the drying process, you can ensure proper ventilation in the room by opening windows or using fans. Additionally, maintaining a moderate temperature and humidity level can also help expedite the drying time.
If you are uncertain about the drying time, it is recommended to refer to the specific instructions provided by the manufacturer of the filler product you are using. They often provide guidelines and approximate drying times for optimal results.
Is it possible to repair large cracks in plaster walls using filler alone?
While it is possible to repair small cracks in plaster walls using filler alone, it may not be as effective for large cracks. Filler alone may not have the necessary strength and stability to hold the plaster together in cases of significant damage.
Large cracks in plaster walls often require additional steps to ensure a proper and long-lasting repair.
One option to consider is using a joint compound or patching plaster in combination with a reinforcing mesh or tape. These materials can provide added strength and support to the damaged area. By applying multiple layers of compound or plaster and embedding the mesh or tape, you can create a more durable repair that is less likely to redevelop cracks in the future.
If you are uncertain about the best approach to repair large cracks in your plaster walls, it is recommended to consult a professional contractor or a skilled plasterer. They can assess the extent of the damage and provide expert advice on the most suitable repair method.
Is there a specific brand or product you recommend for filling cracks in plaster walls?
There are several brands and products that are commonly used for filling cracks in plaster walls. One highly recommended option is a plaster patching compound, such as DAP Plaster Wall Patch or 3M Patch Plus Primer.
These products are specifically designed for repairing cracks in plaster and have excellent adhesion and durability. Another option is using spackling paste, which is a versatile and easy-to-use filler that can also be used for small cracks and holes.
Some popular spackling paste brands include DAP DryDex and Red Devil Onetime. It's important to choose a product that is suitable for plaster walls and follow the manufacturer's instructions for the best results.
Additionally, it's recommended to clean the crack thoroughly and apply a primer before filling it to ensure proper adhesion and a seamless finish.
Should I use a flexible filler for cracks in plaster walls?
Yes, using a flexible filler for cracks in plaster walls is generally recommended. Plaster walls can develop cracks due to various reasons such as settling of the building, temperature changes, or even normal wear and tear.
Flexible fillers are designed to accommodate the movement that can occur in the walls over time, preventing the cracks from reappearing.
Flexible fillers are typically made of materials like acrylic or silicone, which have the ability to expand and contract with the movement of the walls. This flexibility allows the filler to maintain its integrity and prevent further cracking.
Moreover, flexible fillers provide a smooth and seamless finish, blending well with the existing plaster surface.
When choosing a flexible filler, consider factors such as the size and depth of the crack. Some fillers are better suited for smaller cracks, while others are more appropriate for larger ones. It is also important to follow the manufacturer's instructions for proper application and drying time.
In summary, using a flexible filler for cracks in plaster walls is a good idea as it helps ensure long-lasting repair and a professional finish.
What is the best type of filler for cracks in plaster walls?
When it comes to filling cracks in plaster walls, the best type of filler to use is a high-quality joint compound or spackling compound. These products are specifically designed for repairing and patching cracks in plaster surfaces.
Joint compound is a popular choice because it has good adhesive properties and is easy to work with. It is available in various formulations, such as lightweight or fast-drying options, depending on your specific needs.
Spackling compound, on the other hand, is ideal for smaller cracks and dries quickly.
Before applying the filler, it is important to prepare the crack by cleaning it thoroughly and removing any loose plaster. You may also need to widen the crack slightly to ensure proper adhesion of the filler.
Once the crack is prepared, apply the filler using a putty knife, ensuring it is smooth and level with the surrounding plaster.
Ultimately, the best type of filler for cracks in plaster walls will depend on the size and severity of the crack, as well as personal preference. It is recommended to consult with a professional or a knowledgeable salesperson at your local hardware store for specific product recommendations based on your situation.
What is the difference between joint compound and plaster filler for cracks?
Joint compound and plaster filler are both used to repair cracks in walls, but there are some key differences between the two.
Joint compound, also known as drywall mud, is a versatile material primarily used for finishing drywall seams and covering nail or screw indentations. It is made of gypsum powder and various additives, giving it a smooth consistency.
Joint compound is easy to work with, dries relatively quickly, and can be sanded for a seamless finish. However, it is not as durable as plaster.
On the other hand, plaster filler is specifically designed for repairing cracks in plaster walls. It is made of a mixture of gypsum, lime, and sometimes sand or other additives. Plaster filler is more rigid and stronger than joint compound, making it better suited for repairing larger or deeper cracks.
It is typically applied in multiple layers, allowing each layer to dry before applying the next. Once dry, plaster filler can be sanded and painted to match the surrounding wall.
In summary, joint compound is ideal for minor repairs and finishing drywall, while plaster filler is better for more substantial cracks in plaster walls.
