Drywall often suffers from various types of damage, such as holes from hanging decor or dents caused by furniture. Fortunately, repairing these imperfections is nearly as simple as causing them. Handling drywall repairs on your own can save you money and give you a sense of accomplishment, whether you're refreshing a space or aiming to secure your rental deposit. Here's how to confidently address those imperfections with the right tools and a bit of spackle.
Prepare your tools and supplies
For minor drywall fixes, gather a utility knife, putty knife, and sandpaper. For more significant damage, you'll require a hand saw, screw gun, scrap lumber, a drywall patch, and drywall screws. Regardless of the repair size, ensure you have spackle, joint compound, gloves, and a damp cloth on hand.
Repairing minor imperfections in drywall
For small dents or holes, such as those from nails, all you need is spackle and a putty knife. Ensure the area is clean, apply a small amount of spackle, and press it into the hole using the putty knife. Smooth the surface by scraping off excess spackle and leveling the filled area. Once dry, sand the spot until it's even. (Check the product packaging for drying times, though most spackles dry within 30 minutes.)
Addressing medium-sized drywall holes
For larger holes, like those caused by doorknobs or accidental impacts, a patch kit can be helpful. While you can purchase one, you can also create your own using mesh drywall tape and spackle. Start by placing the mesh over the hole, ensuring it extends about an inch beyond the edges. Then, apply a layer of spackle, feathering the edges to blend seamlessly with the wall. Larger patches may require more drying time, so refer to the product instructions. If the spackle shrinks as it dries, a second application might be necessary. Once fully dry, sand the area to a smooth finish.
Fixing substantial holes in drywall
For holes exceeding four inches, a drywall patch is necessary. Before starting, inspect the area for wires, outlets, or switches. If electrical components are nearby, turn off the power to ensure safety. Use a square, tape measure, or straight edge to outline a square or rectangular section around the hole for easier patching. Carefully cut out the marked area with a drywall saw, being mindful of any hidden wires.
Preparing and attaching the patch
After cutting the opening, create a support for the patch using a piece of scrap lumber (at least ¾ inch thick and 2 inches wide). Cut the support slightly longer than the hole's width, angle it to fit through the opening, and secure it inside the drywall with drywall screws. Cut a drywall scrap slightly smaller than the hole, position it using drywall tape, and screw it into the support. Apply a thin layer of joint compound over the patch, covering the seams and feathering the edges. Allow it to dry as per instructions, then sand until smooth.
Repairing drywall cracks
To address cracks in drywall, widen the crack slightly with a utility knife to allow spackle to fill the gap. Use a putty knife to spread spackle over the crack, removing any excess. Let the spackle dry completely, then sand the area smooth. Ensure the entire crack is covered, as even fine edges can lead to reopening if not properly treated.
Final touches: Paint and finish
The final stage of any repair involves painting. If the existing paint is aged, repainting the entire wall may be necessary to ensure a seamless color match. (Applying primer first can effectively conceal the patch; a combined paint-and-primer product may not suffice.) For minor patches and newer paint, a touch-up might suffice. Even if purchasing new paint is required, the results will leave your walls looking flawless and your budget intact.
