How to Drywall an Arch
Learning how to drywall an arch might be easier than you thinkBeginners are often apprehensive about the curved surface of drywall. It’s completely understandable. If you really think you’ll have trouble, you can always install the arch yourself and hire someone to do the drywall for you. But before you make your decision, have a look over this handy, step-by-step guide. You may find that learning how to drywall an arch is easier than you think.
1. Use drywall that is 1/2 -inch thick and fasten it over the arch. Oh, no! Now, your beautiful curves are covered. Time for step two.
2. Cut drywall to archway. It’s time to get your curve back. Use a router with a special bit to cut drywall to make a clean cut along the edge of your arch. (Tip: Google rotozip)
3. Add more screws along the edge of the curve as needed. This will secure the drywall to the MDF and give you a cleaner edge. You’ll definitely need to add some, but how many is up to you and your curve. While learning how to drywall an arch, you’ll be able to see whether you need more screws or not. If it looks like there are open spaces or gaps, add another screw.
4. Repeat on the other side. Just switch sides and follow steps one through three again. When you’re done, both sides of the archway should have drywall.
5. Measure and place a double layer of ¼” drywall under the archway. Here’s a tip: Wet the back of the drywall to help it bend to conform to the curve. Before fastening, slowly work it with your fingers gently creating a curve. Be careful not to break the drywall. Don’t worry if you have to start over as it will take a little bit of time to acquire the feel for bending drywall.
6. Screw the drywall into place. You’re already holding the drywall in place at this point, so just use your drill and screw bit to screw it into place.
7. Now, you’re ready for tape and mud. This is the part where it really helps to be meticulous. Apply very thin layers of mud and then sand them down until your surface is smooth. Don’t forget to leave time for each layer to dry in-between. Taping and compounding is a practice in patience, but it will pay off in the end.
