Walls and Ceilings - How to bend a drywall

If anyone knows how to bend a drywall sheet to make it thmoothly banded please reply.

I'm not sure what you mean, but you can smoothly bend drywall to make a curved wall by scoring across the back in enough places (and close together) to curve it back to fit. Good Luck!

i would start by screwing the ends down on one side then get a damp sponge and wet the sheetrock one section at a time till it bends attaching along the way

I have had to repair a few archways in 1950's and 60's homes, and I use 1/4" drywall because it bends easy without breaking. After the first layer, I simply apply a second layer that brings it out to 1/2" thick. For those of you who haven't tried this, you should. I can do an arch in less than ten minutes with both layers. I have not had to score or wet the drywall with this method. I have also done 1 victorian curved wall with the same results!
