Before constructing arched structures made of drywall material, you need to know how much it can be bent so that it does not break. You may need fluid coomers.
First, for bending drywall, a template is made of different improvised material. It can be like a plywood or drywall itself, current and chipboard slabs. I make a template with a smaller radius of the manufactured surface and already sheet, which is given the required shape. In order to start to bend the workpiece, it is determined which of the parties will compress, then there are many holes on it on the entire surface. The holes should have a depth of half the thickness of the drywall. Also, a conventional awl or a special needle roller is used to make holes. Когда отверстия все сделаны с помощью губки смачивают водой поверхность несколько раз, до тех пор пака поверхность перестанет впитывать в себя влагу. Such work is carried out very carefully and monitors so that the opposite side does not get wet. Further, after abundant wetting, the workpiece is placed carefully on the template and begin to bend lightly. It is necessary to observe the symmetry of the workpiece and template. When drywall is bent and fixed in the right position, they are waiting for its complete drying.
