Types Of Anchors For Plaster
Choosing the right anchor for plaster walls is important for strong support. Different anchors work best depending on the weight and type of item you want to hang. Plaster walls can be fragile, so using the proper anchor prevents damage and holds your items securely.
Plastic Expansion Anchors
Plastic expansion anchors work well for light loads in plaster walls. You drill a hole, push the anchor in, and then screw into it. The anchor expands inside the hole, gripping the plaster tightly. These anchors are easy to use and affordable.
Molly Bolts
Molly bolts are metal anchors designed for medium-weight items. They open behind the wall when tightened, creating a strong hold. Molly bolts spread the load across a bigger area of the plaster. They work well for shelves and mirrors.
Toggle Bolts
Toggle bolts handle heavy loads on plaster walls. They have wings that open inside the wall for extra support. These bolts hold weight by pressing against the back of the plaster. Toggle bolts require a larger hole but offer excellent strength.
Self-drilling Anchors
Self-drilling anchors do not need pre-drilling in plaster. You screw them directly into the wall, saving time and effort. They are useful for light to medium loads. These anchors create a solid grip by cutting into the plaster as you install them.
Tools Needed
Putting anchors in plaster walls requires the right tools. These tools help you work safely and accurately. Each tool has a specific role in the process. Using the correct tools makes the job easier and prevents damage to the wall.
Drill And Bits
A drill is essential for making holes in plaster walls. Choose a drill with variable speed settings. Use masonry or multi-purpose drill bits. The bit size depends on the anchor size. Drill slowly to avoid cracking the plaster.
Screwdriver
A screwdriver is needed to insert screws into the anchors. Use a manual or electric screwdriver. Make sure the screwdriver fits the screw head perfectly. This prevents slipping and damaging the wall or screw.
Hammer
A hammer helps tap the anchors gently into the holes. Use a lightweight hammer for better control. Tap lightly to avoid breaking the plaster. The hammer sets the anchor firmly in place.
Measuring Tape
Measuring tape ensures precise placement of anchors. Measure the distance between holes carefully. Mark the spots with a pencil before drilling. Accurate measurements keep your project neat and balanced.
Preparing The Wall
Preparing the wall is the first step for secure anchor installation in plaster walls. It ensures the anchors hold well and the wall stays intact. Careful preparation helps avoid damage and supports the weight of the items you hang.
Locating Studs
Studs provide strong support behind plaster walls. Use a stud finder to locate them. Move the finder slowly across the wall surface. Mark the edges of each stud with a pencil. Anchoring near studs adds extra strength and stability.
Marking Anchor Points
Choose the spots where anchors will go. Measure and mark these points carefully. Use a level to keep marks straight and even. Marking accurately prevents misaligned holes and weak spots. Double-check measurements before drilling or hammering.
Checking Wall Thickness
Plaster walls vary in thickness. Use a small drill or probe to check depth. This helps pick the right anchor type and length. Avoid anchors that are too long or short. Correct anchor size protects the wall from cracks and holds weight safely.
Drilling The Hole
Drilling the hole is a key step when putting anchors in plaster walls. A clean, well-made hole ensures the anchor holds tight. Take your time and prepare carefully. This avoids cracks and keeps the wall strong.
Choosing The Right Drill Bit
Use a drill bit made for plaster or masonry. Masonry bits work best for hard plaster. Pick a bit that matches the anchor size. Too small or big will make the anchor loose. Check the anchor package for the right size.
Drilling At Correct Depth
Drill only as deep as the anchor needs. Mark the drill bit with tape to guide depth. Too deep holes weaken the wall. Too shallow holes make the anchor stick out. Keep the drill steady and slow for clean holes.
Cleaning The Hole
Remove dust and debris from the hole. Use a small brush or blow air inside. Dust stops the anchor from gripping well. A clean hole helps the anchor stay firm. Double-check before inserting the anchor.
Installing Different Anchors
Plaster walls need strong anchors for secure mounting. Different anchors suit different tasks. Choose the right one to avoid damage and ensure stability. Below are common types of anchors used in plaster walls.
Inserting Plastic Anchors
Plastic anchors work well for light loads. Start by drilling a small hole in the plaster. Push the plastic anchor gently into the hole. Tap it lightly with a hammer if needed. Then, screw into the anchor to hold your item firmly.
Setting Molly Bolts
Molly bolts expand behind the wall for strong grip. Drill a hole matching the bolt size. Insert the molly bolt and tap it lightly. Tighten the screw to spread the anchor behind the plaster. Remove the screw, mount your object, and screw back in.
Using Toggle Bolts
Toggle bolts are perfect for heavy items. Drill a larger hole for the folded toggle. Push the toggle through the hole inside the wall. Pull back so it opens and grips the plaster. Tighten the screw carefully to secure your fixture.
Fitting Self-drilling Anchors
Self-drilling anchors need no pre-drilling. Place the anchor on the plaster surface. Use a screwdriver to twist it in slowly. The anchor cuts into the plaster as you turn. Stop when it feels tight, then insert the screw.
Securing The Fixture
Securing the fixture on plaster walls requires care and precision. Proper attachment ensures the fixture stays strong and safe. It also protects the wall from damage. Follow clear steps to place the fixture firmly.
Aligning The Fixture
Start by positioning the fixture over the anchor. Make sure the holes match the anchors exactly. Hold the fixture steady to avoid slipping. Check that it is level and straight.
Screwing Into Anchor
Use the correct screw size for the anchor. Insert the screw slowly into the anchor hole. Turn the screw gently at first, then tighten firmly. Avoid forcing the screw, which can break the anchor or wall.
Ensuring Tight Fit
Check the fixture for any movement after screwing. Tighten the screws more if it feels loose. Do not overtighten, as it may crack the plaster. A secure fit keeps the fixture stable and safe.
Tips For Strong Support
Strong support is key when putting anchors in plaster walls. Poor support can cause the anchor to fail. Follow these tips to make sure your anchors hold well and keep your items safe.
Focus on careful installation and the right anchor choice. These steps help avoid damage and give your walls better strength.
Avoiding Over-tightening
Do not tighten anchors too much. Over-tightening can crack plaster or strip the anchor’s grip. Turn screws slowly and stop when you feel firm resistance. This keeps the wall and anchor safe.
Choosing Correct Anchor Size
Pick an anchor size that fits the weight of your item. Small anchors fail under heavy loads. Larger anchors spread the weight better. Match the anchor size with the screw and wall thickness for best results.
Distributing Weight Evenly
Use more than one anchor for heavy items. Spread anchors across the wall to share the load. This stops stress on one point. Even weight helps anchors last longer and keeps your wall intact.

Common Mistakes To Avoid
Putting anchors in plaster walls can be tricky. Many people make simple errors that cause damage or weak support. Avoiding these mistakes helps your anchors hold better and last longer.
Ignoring Wall Condition
Plaster walls may have cracks, loose areas, or old paint. Ignoring these signs can cause anchors to fail. Always check the wall carefully before drilling. Fix any weak spots or flaking plaster first.
Using Wrong Anchor Type
Not all anchors work well with plaster walls. Using plastic anchors meant for drywall can lead to poor hold. Choose anchors designed for plaster or masonry. This choice improves stability and prevents damage.
Drilling Oversized Holes
Drilling holes larger than the anchor size weakens the grip. The anchor won’t fit tightly and may fall out. Use a drill bit that matches the anchor size exactly. This ensures a snug and secure fit.
