The obtained arch plane fastened to the guide profiles screws. Below the video how to make an arch made of plasterboard with their hands, visual and detailed instructions.
For the lower bent portion arch also set guide profile. On the walls of the profile of the pre-made cuts (You can use a pair of scissors for metal) steps 3 cm - 5 cm, depending on the radius of curvature. The profile can be easily bent and screwed with screws to the main structure.
Then cut to fit a strip of drywall. To bend it to the required radius on one side makes punctures. It is convenient to use a spiked roller, but you can also use an awl. After that, the strip needs to be wetted with water. Moistened with a broad brush you need to walk on the surface of the drywall 3 fold. Then put the strip at an angle, eg, propped her on a stool, and leave it for a while. Wet drywall strip bends under its own weight. The resulting bent strip is mounted with screws to the main structure.
