Deciphering Your Plaster Wall Type
Before you start drilling, it’s crucial to know what you’re dealing with. Plaster walls aren’t all the same. The two main types you’ll encounter are lath and plaster, and gypsum plaster over plasterboard.
Lath and Plaster
This is the classic type of plaster wall found in many vintage homes, typically built before the 1950s. It consists of wooden or metal strips (lath) that the plaster is applied over.
- Characteristics:
- Often has a slightly uneven or textured surface.
- Can feel very solid, but the plaster itself can be brittle.
- Beneath the plaster, you’ll find the lath, which is a good anchor point if you can hit it.
- Challenges:
- The plaster can chip or crack easily if too much force is applied.
- Locating studs or lath can be tricky.
Gypsum Plaster Over Plasterboard (Drywall)
In some cases, older homes may have had plaster applied over drywall. This is more common in renovations or additions from the mid-20th century onwards.
- Characteristics:
- May have a smoother surface than traditional lath and plaster.
- The underlying structure is drywall.
- Challenges:
- The plaster layer can be thin, and going too deep can damage the drywall.
- You’ll need to account for the plaster thickness and the drywall.
How to Test Your Wall
A simple way to test is to tap gently on the wall. Lath and plaster will often sound more solid and resonant, while drywall might sound hollower. You can also try drilling a very small pilot hole in an inconspicuous spot (like behind a heavy piece of furniture or in a closet) to see what you encounter.
Tools for the Job: Your Hanging Arsenal
Choosing the right hanging tools plaster is key to a successful and damage-free hanging plaster experience. Here’s a breakdown of essential items:
Essential Hanging Tools
- Stud Finder: Crucial for locating wooden studs or the metal lath in lath and plaster walls. This is your primary goal for secure art plaster mounting.
- Drill: A cordless drill is a must-have. You’ll need various drill bit sizes for pilot holes and anchor insertion.
- Screwdriver Set: For driving screws into anchors or directly into studs.
- Hammer: Useful for tapping in some types of anchors or for gently persuading stubborn fixtures.
- Level: Essential for ensuring your artwork is straight.
- Measuring Tape: For accurate placement of your art.
- Pencil: For marking drill points.
- Safety Glasses: Protect your eyes from plaster dust.
- Dust Mask: Plaster dust can be fine and irritating.
Specialized Fasteners for Plaster Walls
This is where we get specific about secure art plaster mounting. Standard drywall anchors might not be suitable for brittle plaster.
Plaster Wall Anchors
These are your best friends when you can’t hit a stud or lath. They are designed to distribute weight and grip securely within the plaster.
- Toggle Bolts: These are excellent for heavier items. They have a spring-loaded wing that opens up behind the plaster wall, creating a broad surface area for support.
- Pros: Very strong, good for hanging heavy art plaster.
- Cons: Require a larger hole, can be a bit tricky to install if the hole is too small or too large.
- Molly Bolts (Sleeve Type Anchors): These metal anchors have an expanding sleeve that tightens against the back of the plaster as you drive the screw.
- Pros: Good holding power, relatively easy to install.
- Cons: Can sometimes crush brittle plaster if overtightened.
- Threaded Wall Anchors (Screw-in Anchors): These plastic or metal anchors have threads that bite into the plaster as you screw them in.
- Pros: Easy to install, minimal hole size.
- Cons: Generally suitable for lighter to medium-weight items.
Wall Plugs Plaster (Wall Plugs/Sleeve Anchors)
Often used interchangeably with some types of anchors, wall plugs typically refer to the plastic or nylon sleeves that expand when a screw is driven into them. For plaster, you want ones specifically designed for plaster or that offer a good grip.
Plaster Wall Hooks
These are often heavy-duty hooks designed to screw directly into plaster or into an anchor. Many come with their own screws and are rated for specific weight limits.
- Screw-in Hooks: Simple hooks with threaded shafts.
- Hook with Wall Plug: Many come packaged with suitable wall plugs plaster for plaster walls.
Planning Your Picture Hanging Plaster Project
Thoughtful planning prevents damage and ensures your art looks its best.
1. Determine the Weight of Your Artwork
This is the most critical step. You need to know the exact weight of the piece you’re hanging. If the artwork doesn’t have a stated weight, weigh it yourself using a bathroom scale or luggage scale.
2. Choose Your Hanging Method
Based on the artwork’s weight and your wall type, select the appropriate hanging method.
Hanging Light to Medium Weight Art
For unframed prints, small canvases, or framed photographs without heavy glass:
- Picture Hooks with Nails: Traditional picture hooks with small nails can work, but only if you can find a stud or the lath. If you’re just nailing into plaster alone, these will likely pull out over time.
- Adhesive Strips (for very light items and temporary hanging): While great for drywall, adhesive strips can sometimes pull off paint or even plaster if the plaster is old or brittle. Test in an inconspicuous spot first and use with caution. They are generally not recommended for secure art plaster mounting of anything with significant value.
- Small Screw-in Anchors with Hooks: For lighter pieces, small threaded wall anchors plaster or screw-in anchors with a hook attachment are a good option.
Hanging Heavy Art Plaster
For larger canvases, framed artwork with glass, mirrors, or anything over 5-10 pounds:
- Locate a Stud: This is always the most secure option. If your stud finder indicates a stud, drill a pilot hole directly into it and use a strong screw.
- Use Heavy-Duty Anchors: If a stud isn’t available, you’ll need robust plaster wall anchors like toggle bolts or heavy-duty molly bolts. These are essential for hanging heavy art plaster safely.
- Multiple Hanging Points: For very large or heavy pieces, use two or more hanging points spaced apart to distribute the weight.
3. Consider Placement and Height
- Eye Level: Generally, the center of the artwork should be at eye level, which is typically around 57-60 inches from the floor.
- Room Layout: Consider how the art fits with your furniture and other decor.
- Lighting: Ensure the artwork is well-lit.
- Avoid Hazards: Keep art away from heat sources, direct sunlight (which can fade colors), and high-traffic areas where it might get bumped.
The Art of Drilling Plaster Walls
Drilling plaster walls requires a delicate touch to avoid cracking.
Pre-Drilling Considerations
- Pilot Holes: Always drill a pilot hole, even if you’re using a self-tapping screw. This makes it easier to drive the screw and reduces stress on the plaster.
- Drill Bit Size: The drill bit size should match the size recommended for your chosen anchor or screw. Check the anchor packaging for guidance.
- Drill Speed: Start with a slow speed and gradually increase if needed. High speeds can generate heat and stress the plaster.
- Depth: Be mindful of how deep you are drilling. You don’t want to go through the entire wall or hit unexpected obstacles.
Step-by-Step Drilling Process
- Mark the Spot: Use a pencil to mark precisely where you want to drill. Use your level to ensure the mark is accurate.
- Start Slow: Place the drill bit on your mark. Start drilling at a very low speed.
- Apply Gentle Pressure: Let the drill do the work. Don’t force it. If you encounter resistance, ease up.
- Drill to Depth: Continue drilling until you reach the desired depth for your anchor or screw.
- Clear Debris: Once drilled, you can use a vacuum cleaner with a brush attachment to carefully remove any loose plaster dust from the hole.
Dealing with Unexpected Obstacles
Sometimes, you might hit something unexpected.
- Old Wiring or Pipes: If you suspect you might hit these (especially in very old homes), reconsider your hanging location or consult a professional.
- Lath: If you hit wood lath, you have a good anchoring point. If you hit metal lath, you’ll likely need to use an anchor that can grip the plaster around it.
Installing Your Chosen Fasteners
Proper installation of your plaster wall anchors is crucial for secure art plaster mounting.
Installing Toggle Bolts
- Drill the Hole: Drill a hole large enough for the toggle wings to pass through. This size will be specified on the toggle bolt packaging.
- Fold the Toggle: Fold the spring-loaded wings and thread them through the hole.
- Pull and Tighten: Pull the bolt back towards the wall so the wings expand behind the plaster.
- Insert Screw: Thread the screw through the artwork’s hanging hardware and into the toggle bolt. Tighten securely.
Installing Molly Bolts
- Drill the Hole: Drill a hole according to the molly bolt’s specifications.
- Insert the Anchor: Push the molly bolt into the hole.
- Drive the Screw: As you drive the screw, the sleeve will expand and grip the plaster. Stop when the screw is snug, but don’t overtighten, as this can crush the plaster.
- Remove Screw (if needed): For some molly bolts, you’ll remove the screw after the sleeve has expanded, leaving the sleeve in place to accept a new screw.
Installing Threaded Wall Anchors
- Drill a Pilot Hole: A small pilot hole is often recommended, even for these.
- Screw in the Anchor: Use a screwdriver to screw the anchor into the hole until it’s flush with the wall surface.
- Insert the Screw: Drive the appropriate screw into the anchor.
Alternative: Damage-Free Hanging Plaster Solutions
If you’re in a rental or prefer not to drill, there are damage-free hanging plaster options, though they may have limitations.
Adhesive Hooks and Strips
- Considerations: These are generally best for very lightweight items. Test on an inconspicuous area first, as some plaster surfaces can be delicate and the adhesive might pull off paint or the plaster itself. They are not ideal for long-term secure art plaster mounting.
- Brands: Products like Command Strips offer a range of weight capacities, but always check if they are recommended for plaster walls and adhere to their weight guidelines strictly.
Picture Hanging Systems (Wire and Rail Systems)
- How they work: These systems involve installing a rail near the ceiling, and then using wires or cords that hang down to attach to your artwork. The rail itself needs to be securely mounted, typically into studs or using robust wall anchors.
- Pros: Allows for easy rearrangement of art without creating new holes.
- Cons: The initial installation of the rail requires secure mounting, which can involve drilling.
Hanging Heavy Art Plaster Safely
When dealing with significant weight, every step needs extra attention.
- Prioritize Studs: If you can find a stud, use it. This is the most reliable method for hanging heavy art plaster.
- Heavy-Duty Anchors are Non-Negotiable: For anything substantial, toggle bolts or heavy-duty molly bolts are essential.
- Check Weight Ratings: Always ensure the anchors and screws you use are rated for well above the weight of your artwork. It’s better to be over-engineered than under-engineered.
- Use a Helper: For large or heavy pieces, have a second person assist you. They can help hold the art in place while you secure it, and also help with lifting.
- Secure Wire/Cord: Ensure the wire or cord on the back of your artwork is also rated for the weight of the piece and is securely attached to the frame.
Maintaining Your Plaster Walls
Even with the best practices, plaster can be delicate.
- Clean Up Dust: After drilling and hanging, clean up all plaster dust promptly.
- Avoid Over-Tightening: Never overtighten screws or anchors, as this can crack the plaster.
- Gentle Cleaning: When cleaning your art or the wall, use a soft cloth and avoid abrasive cleaners.

Frequently Asked Questions (FAQ)
Q: Can I just nail a picture hook directly into plaster?
A: For very lightweight items and if done carefully into solid plaster (not crumbling), it might hold temporarily. However, for secure art plaster mounting, especially for anything with any weight, it’s not recommended as plaster can be brittle and the hook can pull out. Always aim for studs or use appropriate plaster wall anchors.
Q: What’s the difference between drywall anchors and plaster wall anchors?
A: Drywall anchors are designed to grip the softer, paper-based drywall. Plaster walls are harder and more brittle. Plaster wall anchors, like toggle bolts or specific molly bolts, are designed to distribute weight over a larger area or grip the plaster more securely without crushing it.
Q: How do I find studs in a lath and plaster wall?
A: A good electronic stud finder can sometimes work, but they can be unreliable on plaster. The most reliable method is to drill a small pilot hole and probe gently with a thin wire or a small screwdriver to feel for wood (lath or stud). You can also tap the wall and listen for changes in sound that might indicate a stud.
Q: My plaster wall is crumbling. What should I do?
A: If your plaster is significantly damaged or crumbling, it might be too weak to hold even light artwork securely. You may need to repair the plaster before hanging anything, or consider alternative hanging methods that put less stress on the wall. For significant damage, consulting a plaster specialist is advisable.
Q: Can I use screws directly into plaster without anchors?
A: Only for the absolute lightest items, and even then, it’s risky. Screws alone lack the surface area to grip brittle plaster effectively, and they are likely to loosen or pull out over time, potentially causing damage.
By following these guidelines and using the right hanging tools plaster, you can confidently hang your art on plaster walls, ensuring your pieces are displayed beautifully and securely for years to come.
