How To Bend Drywall
Recently, the question came up
on how do you bend drywall around curved or radius walls. One
might not have to apply drywall to a curved surface very often,
but its good information to have when you do.
Depending on the size of the
curve or radius that is being covered, will determine what
thickness of drywall will be used. A radius of 2 foot or
smaller may require multiple layers of 1/4" thick drywall.
Normal residential drywall applications use 1/2" drywall to
finish walls. In this case two layers of 1/4" would be
The trick is to get the
drywall to bend. To do this the drywall needs to be wet. The
best way I have found is to put water on the drywall is with a
garden sprayer. The easiest way to control the bending of the
drywall is to lay it in a form matching the radius of the wall,
soffit, ceiling or whatever the application might
The last drywall bend I did I
had the benefit of using the actual wall section to use as a
form. It was an eight foot high wall, framed to a three foot
radius. Only one side of the wall was being covered, the inside
radius. We decided to cover the radius with one layer of 1/4"
plywood and one layer of 1/4" drywall to match the 1/2" on the

inside radius down, on the floor. The overall length of the
radius was just under eight feet. We laid two sheets face down
over our form. We then started spraying the back side of the
drywall with water. As we applied the water, the drywall
started bending immediately. It didn't take very much water or
time to get the ends of the drywall to droop down and touch the
We let the dampened drywall
lay on the form overnight to dry. The next day when we lifted
the drywall from the form, it kept the shape of the radius.
When it came time to glue and screw the drywall to the curved
framing, it fit like a glove with very little if any stress to
Its not very often that one
gets to hang drywall on a curved wall, but with a little
knowledge, you'll look like a professional.
