How to build arches
1. (Picture left) Frame the wall as you would any other wall, except you will
make the opening the size you want your arch opening to be.
This opening is 5 ft. Notice that there is no header. This
is a non load bearing wall, so frame it with just the top plates in the opening.
If you have a load bearing wall - (picture on right) build the wall with required header,
with king studs and jack studs.
2. Hang the drywall as you would any other wall. Screw it off as required.
You can make arch any size or design you want - just draw it - then cut it out!
3. With a pencil make a mark 6 “ in - Then make a mark at center – 2' 6 "
Then 6 “ in from other end. A good height for the opening is 84".
Now use a string or tape measure and
pin the string at the bottom of the sheet at 2”- 6”(center) – draw/ scribe the arch to each corner.
Cut the drywall out.
4. Cut two 6 inch blocks for the ends. Use 2”x4” or 2”x6” depending on what you framed the wall with. Install one into each cavity at ends. Use drywall screws.
Cut a series of blocks 3 inches long to place in the arch. The short pieces will allow you to follow the curve of the arch.
5. Wrap the opening with drywall (get it wet with a sponge on both sides) carefully
bend it into place screwing it off as you go. If you have a problem with the drywall bending then use masonite hardboard 1/8"or 1/4" sold at most building centers. It will bend around anything. Install it with the rough side out so the mud will grab good.
6. Install arch corner bead and coat it with hot mud or all purpose.
Remember you can create any opening size or design you wish - just mark it on the sheet and cut it out. Fill opening with 3 inch long pieces of wood blocks.
