With careful installation and proper framing methods – tightly curved walls (& ceilings) are possible.
In order to get plasterboard to “curve” it’s best/easiest to be in hot/humid conditions, however, in Victoria, we all know that this is definitely not the case!
To get the curve we wet the plasterboard in a specific way to allow it to curve as we need it.
To ensure a smooth finish, it’s very important that the builder has completed an accurate frame with consistent angles so that the laying of plasterboard is a lot smoother!
