How to Bend Drywall

Bending drywall takes a bit of practice, but with some time, it can be done easily. Most tight spaces can be drywalled if you have the know-how. For most curves, you can simply wet the board and bend it to the required degree. For tighter curves, the drywall can be scored. To do this right, you’ll have to take it step-by-step and here’s how.

Choosing the Drywall

Make sure you have the right size drywall for the curve you have. Thin drywall will break if it is bent too much. Try using the following specs when choosing a thickness for the proper curve:

    • 15-foot radius: 5/8 in.
    • 10-foot radius: ½ in.
    • 7-foot radius: 3/8 in.
    • 5-foot radius: ¼ in.


All you will need to bend drywall is some water, a sponge and a scoring knife. For a wider circumference, you will not need the scoring knife. If you don’t have a sponge, try using a paint roller or another item that can wet large surfaces with relative ease.

Wetting the Drywall

Start by wetting both sides of the drywall with the sponge. It won’t take much water, and you should start to notice the drywall becoming more pliable before too long. Be careful not to use too much water, because the drywall will start to break.

If you have a particularly tight radius, score the drywall every 1-2 in., as well as wet the board. When creating the curve, let the paper only slightly break as you bend it.

Forming the Curve

If you have a form in which to put the drywall, use it to create the curve of the drywall. You can also bend the drywall into the shape of the radius and leave it overnight until it dries. Do not try to put up your drywall before it dries. Once the drywall has dried, it will hold its form.

Be careful about how much pressure you put on the drywall, too much and it will snap. The next day you’ll be ready to nail down your drywall and move onto bigger and better things.

Practice Patience

Take your time when you take on this project. A rushed job can end up in multiple pieces of scrap drywall on your floor and none on your walls. Don’t force the form, use a firm but careful approach when bending your drywall.

It may take a few pieces of drywall before you get the hang of how to bend it, so you might want to purchase an extra sheet or two for those ‘just-in-case’ moments. With a bit of practice, you’ll be bending drywall like a pro.
