If the sheet thickness is from 9mm to 12.5mm, then drywall sheets can be dry bent. The radius of curvature in this case will be from 1 m to 2.75 m. The sheet is pre-cut to size. It is also necessary in advance to assemble a frame to which the drywall will be attached. It should be remembered that drywall bending can only be done along the sheet. If bent across, the sheet will break. One edge of the sheet needs to be fixed to the frame, and a small weight is hung on the other edge or an effort is applied. Gradually, the load must be increased until the sheet takes the required shape. After that, the sheet is fixed to the frame with self-tapping screws, and the load is removed. In this way, it is better to bend drywall with a partner. Recall that there is a more detailed instruction -how to bend drywall for an arch, it covers the main 4 ways of bending with a video example. After mastering the bending technology, you can easily make beautiful curly drywall structures with your own hands.

An easier and safer way to bend a drywall sheet is the wet method. To begin with, a sheet or an element previously cut to size must be rolled with a needle roller on one side. If there is no roller, you can make punctures with an awl, but this will take a very long time. After that, the surface must be moistened with water. To do this, you can use a roller, brush or sponge. The surface is wetted with water at room temperature for 10 minutes, until it becomes like a mirror. When dry, drywall becomes very flexible, and after drying, its strength properties return to it. A sheet well soaked in water is laid on a frame template. Then they slowly bend themselves or allow them to bend under their own weight. Then the edges are fixed with clamps and allowed to dry for 24 hours. After complete drying, the sheet of drywall will remain in a curved state and can be removed from the frame. The necessary elements can be cut out of the sheet or used entirely in curved structures.

There is another way how to bend drywall to create curved, curved drywall structures. To do this, it is necessary to make cuts with a sharp knife on the sheet on one side. The cuts are made perpendicular to the bend line. The frequency of notches depends on the bend radius - the smaller the radius, the smaller the notch pitch. For the construction of columns and chimneys, cuts on the sheet should be made on the outside, and for the construction of arches - on the inside. With this method, the bend is stepped rather than smooth. For smooth lines, you must use a milling machine. It can cut U-shaped or V-shaped notches. All gypsum is selected from the grooves to the sheet of cardboard. The step of the grooves is chosen according to the same principle as when cutting drywall with a knife. If there is no cutter, then the notches can be made with a knife, but it will take time. And now we watch video examples of work.
