How do you bend a sheet a drywall into a curve? I tried wetting the back surface with a paint roller, letting it soak for 30 minutes, then scoring the back paper in parallel lines about an inch apart where I wanted the curve. When I screwed it to the studs, though, one of the scores turned into a break and the sheet became angled rather than curved.
In this specific situation the curve was probably about 10 degrees over the span of 6 inches. Is this too tight a bend for standard drywall?
