- Installing different types of hardware for various weights
Let’s make hanging things on your plaster walls simple and stress-free.
Why Plaster Walls Can Be Tricky to Work With?
Plaster walls present unique challenges that modern drywall doesn’t have. The thin, brittle nature of plaster means it breaks rather than flexes when under stress. This makes even simple tasks like hanging a picture frame more complex.
The structure of plaster and lath walls includes two distinct layers working together. The outer plaster layer is just 1/4 to 1 inch thick, while behind it sit horizontal wooden strips (lath) attached to wall studs.
Standard hanging methods often fail with these walls. Hammering directly into plaster causes cracks while finding studs becomes tricky with wood lath throughout the wall.
Older plaster may also contain hazardous materials like lead or asbestos, adding safety concerns to any project. The age of the walls also factors in; decades-old plaster tends to be more fragile and prone to damage.
Working with plaster walls requires specific tools, techniques, and a good amount of patience.
Hanging on Plaster Walls: Step-By-Step Breakdown
Tools Needed:
| Tool | Purpose | Quantity |
|---|---|---|
| Drill with variable speed settings | For driving screws and drilling holes | 1 |
| Titanium nitride-coated drill bits | For creating precise, durable holes in materials | Set of various sizes |
| Strong magnet for stud finding | To locate studs behind walls for secure screw placement | 1 |
| Hammer | For driving nails in lightweight hanging projects | 1 |
| Pry bar | To create tension when using toggle bolts | 1 |
| Safety gear (goggles, mask) | To protect eyes and lungs during construction work | 1 set per person |
| Pencil | For marking the spots on the wall where screws or nails should go | 1-2 |
| Measuring tape | For measuring the length and height for proper placement | 1 |
| Level | To ensure straight hanging of items | 1 |
Materials Needed:
| Material | Purpose | Quantity |
|---|---|---|
| Screws of appropriate length | To securely fasten drywall or other materials to studs | 1 box per project |
| Toggle bolts for heavy items without studs | To secure heavy items to the wall when no stud is available | As needed |
| Nails for lightweight items | For hanging lightweight objects like pictures or decor | 1 pack |
Step 1: Identify What You’re Hanging
First, consider the weight of your item. This will determine which method you use and where you need to place your hardware.
Step 2: Find a Stud (For Heavier Items)
Use a strong magnet to locate nails in the lath. Since the lath is nailed to studs, these nails show where the studs are.
Step 3: Mark Your Spot
Once you find the right spot, mark it clearly with a pencil. Double-check your measurements and use a level if needed.
Step 4: Pre-Drill Your Hole
Always pre-drill through plaster. Never hammer directly into it, or it will crack and break apart.
Step 5: Choose Your Hardware
For light items, a nail at an angle works well. For medium items, use screws into lath. For heavy items, use screws into studs or toggle bolts.
Step 6: Carefully Install Hardware
When drilling or screwing, go slow and steady. Rushing can crack the plaster around your hole.
Step 7: Test Before Fully Loading
After installing your hardware, test it with a gentle pull before hanging your actual item at full weight.

Tips for Avoiding Common Mistakes
1. Don’t Hammer Directly Into Plaster
- Why It’s a Problem: Unlike drywall, plaster is brittle and can’t withstand direct hammering. This can cause cracks around nails, which may spread over time.
- Long-Term Damage: Even small cracks can grow, leading to bigger repairs later.
- Solution: Always pre-drill before hanging anything, even small items. This extra step can save time and prevent wall damage.
2. Proper Pre-Drilling Technique
- Start Small: Begin with a pilot hole to guide the larger drill bit. This prevents chipping.
- Angle for Nails: When making holes for nails, angle your drill slightly upward to create a secure pocket in the lath.
- Clear the Hole: Remove dust from the hole before inserting screws or nails to ensure they fit properly.
Types of Items You Can Hang on Plaster and Lath Walls
1. Lightweight Items
Angled nails can be used for small picture frames, light wall clocks, or simple décor under 5 pounds. Pre-drill a hole at an upward angle to catch the wood lath behind the plaster.
This method works well for items that won’t be touched or bumped often. The lath alone can support these weights without finding a stud.
2. Medium to Heavyweight Items
Items between 5-20 pounds need more support. Wall-mounted shelves, medium mirrors, or larger photo frames require screws that go into the lath or preferably a stud. Use a magnet to find the studs for best results.
Toggle bolts work well for items without stud access. They grip the back of the lath to distribute weight more widely.
3. Extra Heavy Items
Large mirrors, heavy shelving units, or items over 20 pounds need serious support. Always find and use wall studs for these.
Pre-drill carefully and use screws long enough to go through plaster, lath, and at least an inch into the stud. For extremely heavy items, consider multiple mounting points to spread the load across several studs.
Easy Steps to Keep Your Wall in Good Shape
- Mark your spot carefully: Use a pencil to mark exactly where you’ll drill. Measure twice before making any holes. This careful planning prevents multiple holes if you make a mistake. Consider using painter’s tape around your drilling area for more precise marking.
- Control your drill speed: Set your drill to a medium speed instead of full power. Fast drilling creates more heat and vibration that can damage plaster. Let the drill do the work without applying too much pressure. A gentler approach prevents cracks from forming around your hole.
- Vacuum as you work: Hold a vacuum nozzle near the drilling spot to catch dust as it forms. This prevents plaster dust from spreading throughout your room. For a simple solution, have someone hold the vacuum or tape the nozzle nearby. Cleaning as you go makes the whole job easier.
- Support the surrounding area: Place your free hand near the drilling spot to stabilize the wall. This helps absorb some of the vibration from drilling. Supporting the wall reduces the chance of cracks forming beyond your drill site. Think of it as bracing the plaster while you work.
- Drill at a slight angle: Angle your drill bit slightly upward when making holes. This creates a hook-like path for nails or screws to grip the lath better. The angle should be subtle, just 5-10 degrees up from horizontal. This technique drastically improves the holding power of your hardware.
Conclusion
Hanging items on plaster walls doesn’t have to be tough. With the right tools and methods, you can put up pictures, shelves, and mirrors without causing damage.
Remember these key points: always pre-drill your holes, use the correct hardware for the item’s weight, and find studs for heavy things. The wooden lath gives you more hanging options than you might think.
Take your time, work carefully, and your walls will stay in good shape. Small steps, like drilling at an angle and using the right drill bits, make a big difference in your results.
Now you know how to work with your plaster walls, rather than fighting against them. Your old home can display all your favorite items just as well as any modern house.
