How to build a drywall arch

This step by step diy article is about how to build a drywall arch, on a metal or wooden frame. Building a metal stud frame arch is not as difficult as it might look at first glance and we show it in this article. You can build your archway in any room: in your kitchen, living room or in the hallway, as to add style and personality to your home. This project can take up to a couple of days, if you aren’t experienced, but we can assure you the hard work it will pay off eventually.

Building an archway in a door opening is usually a weekend project, provided you use the right materials, tools and techniques. The most important step is to draw the ellipse in a proper manner, otherwise the hard work will be in vain. Place screws at both ends of the drywall sheet and use a piece of string to guide you when drawing the mark line. Using a longer piece of string will increase the radius of the curve and make it steeper.

In order to build a doorway drywall arch, you need the following:

Materials:

  • Drywall boards
  • Drywall screws
  • Metal track and studs / wooden studs and plywood

Tools:

  • Safety gloves, glasses and respiratory mask
  • Measuring tape,  framing square, pencil
  • Electric screwdriver
  • Utility knife
  • Metal snips / circular saw

Tips:

  • When drawing the arch ellipse, use a smart setup, for a professional look
  • Build a metal or wood stud frame, according to your needs

 

Building a metal stud frame for the drywall arch

Before building the drywall arch

Before building the drywall arch

First, decide the place where to build it. In our case, we will build the drywall arch inside of a door opening. Nevertheless, you can virtually build a drywall archway in any place inside your house.  Next, measure the dimensions of that specific area. Afterward, you should begin building the arch frame, using either metal or wood studs. Each approach has its own advantages: the metal is perfectly straight and very light, as the wood studs are very resistant. Use metals studs for brick walls and wood for timber walls.

After you have drawn the arch on the drywall board, you should cut it, using a jigsaw or a drywall saw. During the operation, make sure you locked firmly the drywall board, otherwise you can injure yourself, or damage the material. The jigsaw’s blade should cut the drywall exactly over the drawn line, so work carefully to make a good job.

Smart tip: Use drywall blades for the jigsaw, for a precision cut.

In order to get the desired drywall arch, you could make several attempts till you obtain a form to fit your tastes and needs.

After you have fixed the metal studs in screws, you can continue the process by installing the first sheet of drywall. In order to make a professional operation, we recommend you to use an electrical screwdriver with torque control. If you install 1/2” drywall, then you should use 1-1/4″ drywall screws, as if you are installing 5/8” drywall, then a better option would be 6 x 1-5/8″ screws.

In this image you can see how you should fasten the metal studs on a concrete wall. Consequently, you should use a drill machine to drill holes, install dowels and then drive the screws to fix the metal stud frame.

However, if you  install the metal studs on wooden walls, you show use only 2” wood screws. The distance between screws should be around 5”/ 12 cm.

Continue the process by installing the other side of the drywall arch in the same manner as in the previous steps. Use an electrical screwdriver and install the screws as their heads to be level with the drywall surface, otherwise you will have to repair the surface with drywall mud.

Smart tip: Install screws along the metal stud frame, every 57’/15 cm or so, as to fix firmly the drywall arch.

Next, you have to install a curved metal stud on the edge of the drywall arch, for a better rigidity of the frame.

Consequently, measure the archway and cut with metal snips a metal stud with at that exactly dimension. Don’t forget to use safety gloves, as to avoid cutting yourself in the sharp edges.

Smart tip: To make a curved metal stud, just cut the both side skirts, every 5”/12 cm. In this way, you will obtain a metal stud to fit any curved form.

If you have cut the metal stud according to our recommendation, you can proceed to the next stage. Remember to use safety gloves, as you could easily cut yourself in the edges of the metal stud.

The curved metal stud should be fixed in the following manner: start with one end and bend the  metal stud as to fit the archway. Next, fix the curved stud to the metal frame with screws, as to lock it into position.

After you make sure the both ends of the curved metal stud are connected to the metal frame, you can continue the process by fastening the drywall arch to the metal track with screws, by using an electric screwdriver.

If you have to bend more the metal stud, just make more cuts along its side skirts and it will fit properly into position.

This step is very important for the construction of your archway, so pay attention and make sure the drywall board is well locked to the metal frame. The screws must be inserted every 7”/15 cm, as to get a straight surface.

Remember that the frame is not completed until you fix a perpendicular metal stud, which has to link both curved arches. This perpendicular metal stud must be placed at the maximum point of both arches.

Building a wooden frame for your drywall arch is easy. You should first measure the door opening. Then subtract the drywall plus plywood thickness (1”/2 cm) and you will get the thickness of your wood studs. Consequently, use 1” plywood, draw the ellipse and cut it using a jig saw.

Afterwards, fasten with 2” screws the wood studs to build the basic frame of the arch.  Then attach the arch to the opening door with long wood screws every 7 inch/15 cm.

The final step is to fasten the other plywood boards, and then the drywall boards. The drywall should be fastened with drywall screws, as to make sure it is locked into position.

Before starting the project, make a detailed plan to calculate the right dimensions of the drywall arch, as to fit perfectly in the door opening.

After we have built the frame and we have installed the sides of the drywall arch, we have to complete the project by fixing the bottom section.

Consequently, measure the distance with a measuring tape (the width and the length of the curved arch). Next cut a piece of drywall exactly to that specific dimensions, using an utility knife and a t-square.

After we have obtained the rectangle, we used one of our little tricks to make the drywall bend. We used a spirit level and cut straight lines every 4”/10 cm with an utility knife, just to go over the paper layer. After we have applied the technique to the whole surface of the drywall rectangle, we turn it with the cuts upward. It is essential to use the spirit level, or a T-square  as to make sure the cuts are perpendicular on the side edges and parallel between them.

After you have turned the drywall with the cuts oriented upward, you can continue the project by fixing it to the bottom of the arch.

Make sure you don’t apply too much force when you bend the drywall, as you risk damaging the board. Just use the small-steps technique, and the drywall will get the form of the arch in a matter of seconds.

Next, we have fixed the drywall with several screws starting with the top of the arch. Afterwards, we fasten the drywall board with screws on each side, every 7”/15 cm, using an electrical screwdriver with torque control. Work with good judgment, as you have almost finished building your dream drywall arch.

When installing the drywall rectangle, align perfectly its edges with  the arch walls, on both sides. Also check if the ends of the rectangle fit the archway, otherwise adjust its dimension.

In this image you can see the whole fastening process illustrated. You can also notice that the drywall board gets the curved shaped, step by step, as we install more screws and go along the arch, towards its both ends.

The most important aspect, is to make the cuts on the drywall board every 5-7”/10-15 cm or even closer, otherwise you won’t be able to obtain a professional look to your drywall arch. Be patient and do not hurry the process, as to avoid mistakes. In addition, we reiterate to take all necessary measures to work in safe conditions, as diy projects have their risks.

Smart tip: Another approach you can use for bending drywall is to wet it, but it only works if the slope of the arch is very low. Nevertheless, we will publish a complete guide on how to bend drywall, as soon as possible.

Our arch is on the verge of being completed, as only a small area has to be fastened with screws. You can notice that the right technique is to work in mirror, to fix the bottom drywall starting from center in both directions.

Make sure you work in proper conditions: the area should be well lighted, ventilated and you should use safety gloves and glasses, whenever the situation requires it.

You can notice the pattern of the drywall screws in the imagine, and how you should use the electric screwdriver to insert the screws.

Smart tip: If you are going to install the arch in an area affected by water vapors, you should buy anti-moisture drywall (the green sheets), as it is designed to resist in such harsh conditions, otherwise your drywall arch will deteriorate over time. However, you should think at all these details before you start the project.
