How do you create <45 angle in a ceiling w/greenboard?

doing a bath ceiling over that has an angle to part of it. It was formerly curved with rock lathe and plaster. I am covering it with greenboard and not sure how to create the slight bend so, I think I have to do a slight angle instead. Any suggestions on the bending or any special technique for a small angle change maybe it's a 25 degree.

Thanks all
Jay

If you need to curve the drywall I would use 2 layers on 1/4" rock. It can be gently bent to conform to the curve, 2nd layer makes it as strong as 1/2" IMO you don't need green board as the paint will protect the rock.

Drywall supply houses (commercial) sell a 1/4 rock made just for that. It is called "flex board" (or if you call it that they should know what you mean.

It can wrap a 12" diameter. I have used it a lot, and it is great stuff.

I hope this helps.

Thanks,
But does this stuff get sold with a greenboard cover? It would get used in a bathroom ceiling and I"m concerned about the moisture.

Once the rock is finished, primed and coated with a latex enamel paint it will have sufficent protection from moisture.
