There are two ways to make a sheet of drywall curved - wetting the surface and applying a parallel cuts.The first method is used in the case where only necessary to slightly bend the gypsum board.The second method is useful when a sheet must impart a large curvature.In the latter case, there is an alternative: you can use two layers of plasterboard thickness of 6.5 mm (the so-called Arch drywall), since it is easier to bend, or a layer 6.5 mm plywood plus a layer 6.5 mm plasterboard.

Based on our own experience, we recommend you before you start working with a large sheet of drywall, practice on a scrap.Do this several times, you will realize how easy it is to bend the drywall in the home - you kind of work is quite capable.

Place the sheet on the floor and leaned it against the wall and, using a ruler (in our case - the building level), make a lot of parallel cuts.Incising the paper layer on one side of gypsum board will make it easy to bend it, while remaining intact layer of paper on the other side will hold the sheet from breaking.

Tip: Remember to make notches on the outer surface of the future curve, otherwise you will not be able to bend the drywall correctly.
