Introduction
Whether you are moving out of a NYC rental and want your security deposit back, or just tidying up after rearranging artwork, patching small holes in drywall is one of the most useful DIY skills to have. Small holes from nails, screws, and wall anchors are simple to fix with spackle and a putty knife. Medium holes up to about four inches require a patch kit but are still very manageable. A clean patch job is invisible once painted, and landlords in NYC are much more forgiving of walls that look freshly maintained.
Step-by-Step Instructions

Step 1 Prepare the Damaged Area
For nail and screw holes, use a putty knife to scrape away any raised edges or loose material around the hole. If a wall anchor is still in place, pull it out with pliers or screw it in slightly and pull it free. For holes up to about a quarter inch, you can fill directly with spackle. For holes between one and four inches, you will need a self-adhesive mesh patch from the hardware store. Sand the area lightly around the hole so the filler has a smooth surface to grip.

Step 2 Apply Spackle or Joint Compound
For small holes, load a small amount of lightweight spackle onto a putty knife and press it firmly into the hole, then draw the knife across the surface to smooth it flush with the wall. Slightly overfill the hole since spackle shrinks as it dries. For mesh-patched holes, apply a thin layer of joint compound over the entire patch, extending about two inches beyond the edges in all directions. Feather the edges by gradually reducing pressure as you move outward from the center.

Step 3 Let It Dry and Apply Additional Coats
Lightweight spackle dries in about 30 minutes for small holes, but joint compound over patches needs at least two to four hours per coat. Do not rush this step — applying the next coat over wet compound causes bubbling and cracking. For patch repairs, plan on two to three thin coats, sanding lightly between each with 120-grit sandpaper. Each coat should extend slightly wider than the previous one to create a seamless feathered edge that blends into the existing wall texture.

Step 4 Sand Smooth
Once the final coat is completely dry, sand with 150-grit sandpaper using light circular motions. The goal is a perfectly flat surface that you cannot feel with your fingertips when you run your hand across it. Hold a flashlight at a low angle against the wall to reveal any ridges or low spots. If you find imperfections, apply one more thin coat and sand again. Wipe away all sanding dust with a damp cloth and let the area dry before painting.

Step 5 Prime and Paint
Always prime the patched area before painting, even if using paint-and-primer-in-one products. Bare spackle absorbs paint differently than the surrounding wall, and without primer the patch will be visible as a dull spot. Apply a coat of white primer, let it dry, then paint to match. If you do not have the original paint color, take a chip from an inconspicuous spot to a paint store for color matching. NYC landlords often use flat white on walls and ceilings, making touch-ups easier.
When to Call a Professional
Call a professional for holes larger than four to six inches, which require cutting a new piece of drywall and attaching it to backing supports. You should also call a pro if you discover crumbling plaster behind the drywall (common in pre-war NYC buildings that have been skinned over), if there are signs of water damage or mold around the hole, or if the damage is in a plaster wall rather than drywall — plaster repair requires different materials and techniques.
