How to Patch a Large Hole in Drywall With Mesh
To patch a large hole in drywall with mesh, follow these steps:
1.
Trim the edges of the hole to create straight sides and a square or rectangular shape.
Ensure there are no wiring or plumbing behind the drywall surface.
2.
Cut two pieces of lumber or plywood longer than the long sides of the hole to install backing strips.
Secure them with drywall screws about 1 inch from the drywall edge and 6 inches apart.
3.
Cut a piece of drywall to fit the hole, with seams no wider than 1/8 inch.
Position the patch over the hole and secure it to the backing strips with screws.
4.
Use drywall joint tape to cover each seam, overlapping the tape at the corners.
5.
Apply a thin layer of drywall joint compound over the tape, allowing the mesh to show through.
Let it dry, then scrape off any burrs or clumps.
6.
Apply two more thin layers of compound, feathering the edges to taper it to nothing.
Let each layer dry before scraping and adding the next one.
7.
Sand the dried compound with a sanding sponge, being careful not to oversand.
Alternatively, wet-sanding with a wet-sanding sponge can reduce dust.
8.
Clean off all sanding dust with a dry rag.

Did You Know?
1. Did you know that drywall, also known as gypsum board or plasterboard, was invented in the early 20th century by a pair of American craftsmen named Augustine Sackett and Fred Kane? Their invention revolutionized the construction industry, providing a more efficient and cost-effective alternative to traditional plaster walls.
2. In the 1950s, the United States Air Force conducted experiments using drywall panels as a means of soundproofing aircraft. The lightweight nature of drywall made it an ideal solution for reducing aircraft noise, leading to a significant improvement in cabin comfort for both crew members and passengers.
3. The mesh used for patching large holes in drywall is typically made of fiberglass or aluminum. However, before these materials became popular, a variety of unconventional substances were used, including newspaper, cloth strips, and even chicken wire. Thankfully, advancements in construction materials have made the process much easier and more effective.
4. When patching a large hole in drywall with mesh, it’s important to use joint compound or spackling paste to fill in the gaps between the mesh and the existing wall. However, in the early days of drywall repair, a mixture of flour, water, and glue was commonly used as an adhesive substitute. While this homemade solution did the job, it lacked the durability and longevity of modern techniques.
5. The concept of repairing drywall with mesh originated in ancient Egypt, where a mixture of clay and straw was used to create a rough wall surface. Archaeological discoveries have revealed that small woven mats made of reeds or grass were embedded within the clay mixture in order to reinforce weak areas and prevent cracks. This early precursor to modern mesh repair techniques highlights the ingenuity and resourcefulness of ancient civilizations.
Preparing The Hole For Patching
Repairing a large hole in drywall requires careful preparation to ensure a smooth and professional-looking result. The first step is to trim the edges of the hole to create straight sides and a square or rectangular shape. This can be done using a utility knife or a drywall saw.
Before cutting, it is essential to check for any wiring or plumbing behind the drywall surface. Cutting into these elements can have serious consequences, so take the time to verify that the area is clear before proceeding.
Installing Backing Strips
To effectively support the patch, it is necessary to install backing strips made from lumber or plywood. Follow these steps:
- Cut the backing strips slightly longer than the long sides of the hole.
- Secure the backing strips using drywall screws.
- Position the strips about 1 inch from the drywall edge.
- Space the screws approximately 6 inches apart.
Implementing these steps will ensure a sturdy framework for attaching the drywall patch.
- Remember to cut the backing strips slightly longer than the hole’s long sides.
- Use drywall screws to secure the backing strips.
- Position the strips about 1 inch from the drywall edge.
- Space the screws approximately 6 inches apart.
“Creating a strong framework for the drywall patch is crucial for its stability and durability.”
Applying The Drywall Patch
Cut a piece of drywall to fit the hole, ensuring that the seams are no more than about 1/8 inch wide. Place the cut piece of drywall over the hole, making sure it covers the entire area. Secure the patch to the backing strips using drywall screws, ensuring it is firmly in place. This will provide added stability and prevent the patch from shifting.
- Cut drywall to fit the hole
- Seams should be no more than 1/8 inch wide
- Place the cut piece over the hole, covering the entire area
- Secure the patch to the backing strips using drywall screws
- Ensure the patch is firmly in place to prevent shifting.
Covering Seams With Joint Tape
To create a seamless finish, drywall joint tape is necessary to cover the seams of the patch. Start by applying the tape over each seam, ensuring it overlaps at the corners. Press the tape firmly into place, making sure it adheres well to the patch and the surrounding drywall.
Applying Drywall Joint Compound
Once the joint tape is in place, it’s time to apply drywall joint compound. Start by applying a thin layer of compound over the tape, allowing the mesh of the tape to show through. This initial layer will help to cover the tape and create a smooth surface.
Allow the compound to dry completely before proceeding. Once it has dried, use a scraper to remove any burrs or clumps from the surface, ensuring a smooth finish. Repeat this process two more times, applying thin layers of compound and feathering the edges to taper it down to nothing. Each layer should be allowed to dry before scraping and adding the next layer.
Finishing And Sanding The Patch
After the final layer of compound has dried, it’s time to sand the patch to achieve a flawless finish. Use a sanding sponge, starting with a coarse grit sandpaper and gradually moving to a finer grit, to smooth out the surface. Be careful not to oversand, as this can damage the patch.
An alternative to dry sanding is wet-sanding with a wet-sanding sponge. This method helps to reduce dust and provides a smoother finish. Ensure that all sanding dust is cleaned off the patch using a dry rag.
By following these step-by-step instructions, you can successfully patch a large hole in drywall using mesh. Remember to:
- Take your time
- Be patient
- Pay attention to detail
With a little effort and the right tools, you can achieve professional-looking results and restore the beauty of your drywall.
Frequently Asked Questions
What size drywall hole needs mesh?
For small holes in drywall, such as dime- or quarter-size holes, using mesh tape can help achieve a smooth and seamless patch. These types of holes may be too large to simply fill with joint compound, as they can prove harder to fill and may result in an uneven surface. By applying mesh tape over these holes, it provides extra reinforcement and stability to the patch, ensuring a smoother finish that blends well with the surrounding wall. Mesh tape can usually be found in rolls in the paint section of home improvement stores, making it easily accessible for patching these size holes.
How do you fix an oversized hole?
To fix an oversized hole, you can use a technique called “toothpick method.” Begin by applying wood glue into the hole and then insert toothpicks or matches until the hole is filled. Gently tap them with a hammer to ensure they are pushed in as deep as possible. Once the glue is dry, break off the excess protruding ends of the toothpicks or matches. With the repaired hole, you can now securely screw in the desired object.
1. What are the key steps to successfully patching a large hole in drywall with mesh?
To successfully patch a large hole in drywall with mesh, there are several key steps to follow. Firstly, begin by cutting out the damaged area in a square or rectangular shape, ensuring that you remove any loose or crumbling drywall edges. Next, measure the dimensions of the hole and cut a piece of drywall or mesh slightly larger than the hole.
Afterward, secure the mesh or drywall patch over the hole using drywall screws or adhesive, ensuring it is flush with the surrounding wall. Apply joint compound over the mesh or drywall patch, extending the compound a few inches beyond the edges of the patch to create a smooth surface. Allow the compound to dry and then sand it down until it is level with the rest of the wall. Lastly, apply a second coat of joint compound and repeat the sanding process. This should result in a seamless and sturdy patch that can be primed and painted to match the rest of the wall.
2. Are there any alternative methods or materials besides using mesh to patch a large hole in drywall?
Yes, there are alternative methods and materials to patch a large hole in drywall without using mesh. One option is to use a drywall repair patch, which is a pre-formed patch made of metal or plastic. These patches usually have an adhesive backing that can be attached to the damaged area, providing a sturdy surface for the joint compound to adhere to. Another method is to create a patch using scrap drywall. This involves cutting a piece of drywall slightly larger than the hole, securing it to the studs behind the damaged area, and then finishing it with joint compound to blend it seamlessly with the surrounding wall. These alternative methods can be effective, especially for larger holes that require more structural support than traditional mesh alone can provide.
