Plaster walls present a distinctive obstacle when evaluating the efficacy of drywall anchors. It’s vital to comprehend that standard drywall anchors, including plastic options, are often ineffective in plaster environments. To overcome this challenge, it’s necessary to employ anchors specifically designed for plaster surfaces, such as the trusty molly bolt. This solution involves carefully drilling a precise hole in the plaster and securing the anchor with a threaded screw.
By selecting the suitable anchor for the task, you can guarantee a stable hold, making it unnecessary to resort to hollow anchors or attempt to screw directly into the plaster or drywall, which can be susceptible to mechanical failure.
How Do You Ensure the Anchors Hold Securely in Plaster without Pulling Out?
When it comes to hanging objects in plaster walls, it’s crucial to ensure the anchors hold securely without pulling out. Here’s a step-by-step guide to help you achieve a safe and sturdy installation:
Prepare the Wall
Prior to installing anchors, make sure the plaster wall is clean and dry.
Choose the Right Anchor
Select the appropriate anchor for your specific fixture and plaster type. There are two main types: self-expanding anchors and sleeve anchors. Sleeve anchors work best for hollow walls and provide a secure grip.
Drill Pilot Hole
Create a pilot hole in the wall using a drill bit slightly smaller than the anchor. This helps prevent the anchor from slipping out and ensures a proper hold.
Insert Anchor
Insert the anchor into the pilot hole, ensuring it’s seated properly. Use a wrench or pliers to tighten the anchor.

Final Check
Are There Any Specific Screw Types That Work Better with Plaster than Others?
Fixing screws into plaster can be a bit tricky, but knowing the right type of screw for the job can make all the difference. Here’s a guide to help you choose the best screws for your plaster repair or renovation projects.
Plaster- Friendly Screw Options
- SELF-TAPPING SCREWS: These screws have a built-in point that taps into the plaster as they’re screwed in, making them ideal for smooth plaster surfaces.
- PLASTER-TOUGH SCREWS: These screws are specifically designed to withstand the soft, fragile nature of plaster. They’re usually made of high-strength steel and have a rougher surface to help them grip.
- SCREWS WITH WING NUTS: Screws with wing nuts provide more torque and can help to prevent them from coming loose over time.
- PHILLIPS-HEAD SCREWS: While not specifically designed for plaster, Phillips-head screws can work well if you’re careful not to apply too much pressure, which can cause the plaster to crumble.
Avoid These Screw Types
- SCREWS WITH LARGE HEADS: Large screws can cause the plaster to crack or break when inserted.
- SCREWS WITH COARSE THREADS: These screws can also cause the plaster to crumble or break when inserted.
- SCREWS WITHOUT A POINT: Screws without a point may struggle to penetrate the plaster and may strip the surface around them.
Can You Use Drill-attached Anchors on Plaster Walls or Do You Need to Use Handheld Ones?
When it comes to hanging objects on plaster walls, you have two main options: drill-attached anchors and handheld anchors. But which one is the best choice for the job?
- Drill-Attached Anchors : These anchors require a screwdriver or drill to secure them into the plaster wall. They’re suitable for heavy objects like TVs, shelves, or mirrors. Pros include:
- Strong hold due to the anchor being physically attached to the wall
- Allows for precise placement of the object
- Handheld Anchors : These anchors are spring-loaded and can be expanded to grip the plaster wall. They’re ideal for lighter objects like picture frames, hooks, or small decorative items. Pros include:
- Easy to use and install without special tools
- Can be removed and reinstalled without damaging the wall
However, there’s a catch. Drill-attached anchors are less effective on plaster walls due to the soft and brittle material. They can easily crack or break if the anchor is not properly secured, which can lead to serious damage. Handheld anchors, on the other hand, are more suitable for plaster walls as they don’t require the same level of force to secure.
If you’re looking to hang heavier objects, it’s best to use a combination of both anchors. For example, you can use a handheld anchor to initially secure the object, and then use a drill-attached anchor to provide additional support.
Do You Need to Drill a Hole Specifically for Anchors in Plaster Walls or Can You Just Screw It In?
When it comes to securing anchors in plaster walls, you may wonder if you need to drill a hole specifically for them or if you can simply screw them in. The answer depends on a few factors.
Conditions for Drilling a Hole
- If you’re dealing with a large or heavy anchor (e.g., a picture frame or a piece of furniture), it’s generally recommended to drill a hole for it to ensure a secure and stable hold.
- If the plaster wall is old or brittle, drilling a hole can help prevent damage or cracking.
- If you’re installing an anchor in a load-bearing area (e.g., near a door or window), drilling a hole is often necessary for added support.
Can You Just Screw It In?
- Smaller anchors (e.g., nails or screws) might be okay without a pre-drilled hole, especially if you’re not dealing with significant weight or stress on the anchor.
- However, keep in mind that plaster walls can be prone to cracking or crumbling, even with minor anchors.
- If you do choose to screw in an anchor without drilling a hole, be gentle and avoid applying excessive force, which could exacerbate the risk of damage.
Do Hollow Wall Anchors Work as Well on Plaster as They Do on Drywall?
Hollow wall anchors are designed to help you hang objects securely on walls without damaging the surface. But what about plaster walls? Will they work just as well on plaster as they do on drywall?
In short, hollow wall anchors can work on plaster walls, but the results might vary depending on the type of plaster and the quality of the anchor.
What Are Hollow Wall Anchors?
Hollow wall anchors are small devices that create a hidden anchor point in the wall for hanging objects. They typically consist of a plastic or metal anchor body that expands when a screw or bolt is inserted, creating a strong hold.
Do They Work on Plaster Walls?
Plaster walls, being denser and more brittle than drywall, can be more challenging for hollow wall anchors. However, many modern hollow wall anchors are designed to work on a variety of wall types, including plaster.
- Some hollow wall anchors feature a unique design that helps them grip plaster walls more effectively.
- Other anchors may require a slightly different installation technique to ensure a secure hold on plaster.
- Choose a high-quality anchor designed for plaster walls.
- Make sure the anchor is installed correctly, following the manufacturer’s instructions.
- Test the anchor by pulling gently on the screw or bolt to ensure a secure hold.
- Be prepared for the anchor to work less effectively on thicker, older plaster walls.
- Plaster-specific anchors or screws
- Adhesive-backed hooks or strips
- Magnetic hooks or strips
Is It Possible to Anchor Drywall to Plaster without Using Any Specialized Tools or Materials?
While it’s generally recommended to use specialized tools and materials when anchoring drywall to plaster, it’s not entirely impossible to do so without them. However, the process becomes more challenging and may require some extra effort and creativity.
Here are a few DIY-friendly methods you can try:
- Pegging : Use wooden pegs to attach the drywall to the plaster. This method works best for smaller areas, such as behind a fireplace or in a hallway. Drill a small hole in the plaster, insert the peg, and hammer it gently into place. Then, screw the drywall onto the peg.
- Screws with pilot holes : Use drywall screws with pilot holes to anchor the drywall to the plaster. This method works best for larger areas or where you need more holding power. Drill a small pilot hole into the plaster, insert the screw, and tighten it slowly.
- Adhesive strips : Use strong adhesive strips, such as 3M Command Strips, to attach the drywall to the plaster. These strips come with a removable adhesive that can be reused multiple times. Apply the strip to the back of the drywall and press it firmly onto the plaster.
When using these methods, keep in mind the following:
- Make sure the plaster is clean and free of any debris or old adhesives.
- Use a level to ensure the drywall is securely attached and won’t hinder any future repairs.
- Test the anchor points by applying gentle pressure to the drywall to ensure it won’t come loose.
- Consider using a combination of methods for added stability and security.
While it’s possible to anchor drywall to plaster without specialized tools or materials, it’s essential to remember that this method may not be as secure or durable as professional-grade solutions. If you’re not confident in your DIY skills or need long-term durability, it’s recommended to consult a professional for assistance.
