1. Removing the Old Drywall Anchor
The first and most critical step is to remove the old anchor, as its plastic or metal body will prevent your patch from bonding properly. The removal method depends on the type of anchor used.
Small Plastic Anchors or Screw-in Anchors
How to remove: These are the easiest to deal with. Use a pair of needle-nose pliers to grab the head of the anchor and pull it straight out of the wall. If it’s a screw-in type, simply use a screwdriver to unscrew it.
Why it matters: Attempting to spackle over these will result in a hollow, weak spot and a visible outline of the anchor.
Toggle Bolts or Molly Bolts
How to remove: These anchors expand behind the drywall and are difficult to pull out. The easiest method is to use a screwdriver to push the head of the anchor into the wall cavity, where it will harmlessly drop.
Why it matters: Trying to remove a toggle bolt by force can tear out a large chunk of drywall, turning a small repair into a much bigger problem.
2. Step-by-Step Repair Guide
Once the anchor is gone, you can repair the hole. We'll outline two methods based on the size of the hole you're left with.
For Small Holes (up to 1 inch)
Clean the Area: Remove any loose debris or frayed paper from around the hole. A quick wipe with a damp cloth is all you need.
Fill with Compound: Using a small putty knife, press a small amount of spackle or lightweight joint compound firmly into the hole. Overfill the hole slightly.
Feather the Edges: Scrape the putty knife flat against the wall, removing the excess compound and creating a smooth, feathered edge that blends into the surrounding wall.
Sand and Finish: Once the compound is completely dry, sand it lightly with a fine-grit sanding sponge. If the compound has shrunk, apply a second thin coat, let it dry, and sand again.
For Larger Holes (1-3 inches)
Prep the Hole: Clean the area as above. Because the hole is larger, we recommend using a self-adhesive drywall patch kit.
Apply the Patch: Peel the backing off the mesh patch and center it over the hole. Press firmly to ensure a strong adhesion to the wall.
Apply Joint Compound: Apply a thin, even coat of joint compound over the mesh patch using a 6-inch drywall knife. Make sure the compound covers the entire patch and feather the edges widely.
Final Coats and Sanding: Once the first coat is dry, apply a second, wider coat of joint compound, feathering it out even further. Let it dry completely, then sand the area until it is perfectly smooth and invisible.
3. Pro Tips for a Flawless, Lasting Repair
Don't Skip the Primer: A repaired area will have a different texture and absorption rate than the surrounding drywall. A coat of quality primer creates a uniform base, ensuring your final paint job is seamless and the repair is invisible.
Go Thin with the Mud: As with any drywall repair, always apply multiple thin coats of joint compound instead of one thick layer. This prevents cracking, shrinking, and bubbling.
Use the Right Tool: A small putty knife is perfect for small holes, while a 6-inch drywall knife provides a better feathering surface for larger patches.
Light the Imperfections: Use a flashlight or work lamp held parallel to the wall to highlight any ridges or uneven spots that you may have missed. This technique is invaluable for achieving a truly flawless finish.
If you're dealing with a larger repair, a difficult anchor type, or simply want the peace of mind of a guaranteed perfect finish, it's always best to call a professional.

Understanding Drywall Materials
Drywall, also known as plasterboard, wallboard, or gypsum board, is a common building material used for interior walls and ceilings. It consists of a panel made of gypsum plaster pressed between two thick sheets of paper. The paper face is absorbent and provides a good surface for paint and wallpaper, while the back paper is typically rougher. Understanding the composition of your drywall can help you choose the right repair materials and techniques. For instance, the paper facing can be easily damaged, which is why careful removal of anchors and gentle sanding are crucial for a seamless repair. The core of the drywall is gypsum, which is a mineral that is relatively soft and can be easily damaged if too much force is applied during anchor removal, especially with larger anchors like toggle bolts. Ensuring the integrity of the surrounding paper and gypsum core is paramount to achieving a professional-looking repair that blends perfectly with the existing wall surface.
