How to Hang Sheetrock

Remove the old drywall. Unless you are starting fresh and there is no old drywall, you should remove the old drywall instead of trying to patch up the drywall in pieces. The old drywall will need to be pried from the studs and ceiling joists with a crowbar or other instrument (often the hands once you get started), being careful not to connect with any electrical or other wiring under the drywall.^[3]

Make a thorough job of clearing up the mess. When it comes time to install the new drywall, little pieces left over from the old walls and ceiling will get in your way and make the job more difficult. This would be a good time to pull out the shop vac and run it along the bottom edge of the walls. A broom works well too.

Remove all nails and/or screws from the exposed studs and ceiling joists. They can either be removed or hammered into the wood studs. (It's best to remove them so you don’t hit them with the new nails or screws you will put in later.) Then run a hammer down each stud to make sure you pulled every screw and nail. Every one you miss will produce an ugly blowout.^[4]

Measure out your sheetrock before hanging. This goes for both ceilings and walls. Measure and cut the sheetrock so each end lands on the center of a stud or joist.^[5] Sheetrock joints that are unsupported by a stud or joist will definitely crack. Sand every cut with a Surform plane or rasp or the sheets will not fit. (NEVER use red chalk to snap lines; it will bleed through the finish paint.)

Consider gluing each stud and joist before it receives the drywall. Run a bead of glue down each stud that will be covered by the drywall. Do this immediately before hanging. You don't need to run glue down each stud, but it's recommended, and common practice among professionals.

Hang the toughest part first — the ceiling. The order of hanging the drywall matters. This is a two or three person job if you haven’t rented a drywall “lifter” which lifts the pieces straight up by hydraulics and all you do is nail or screw the pieces to the joists. If you don’t have this machine, build two “T-shaped” supports ("deadmen") to help with this job. Just nail together two 1x3's into a “T” shape, one for each end of the drywall you will be supporting. Make them a little bit more than exact height so you can wedge the sheets to hold them solidly in place. Once the drywall is lifted by hand, the deadmen are slid in under the drywall to wedge it against the ceiling joists while you nail or screw it up. Give up any idea you might have of forcing the sheets into place. They will break or blow out and make a mess.

• Mark the ceiling joist centers on the top plate (to save much cursing). Always start from a corner when hanging. Never start from the center and hang outwards. Start from one corner and move in a straight perpendicular line. Once you have one row finished, move on to the next row.

Mark the stud centers on the ceiling drywall. Make sure to screw or nail the drywall to each stud that it covers. Use a stud finder to locate the stud's position — they should be 16 inches (~40 cm) apart — and then screw or nail four or five evenly-spaced screws into the drywall along the studs.

• Be sure to install the drywall perpendicular to its framing, whether you're working the ceiling or walls. Because of how drywall is constructed, its strength (dimensional strength bias) runs along the length. This means that it is best to hang it perpendicular, not vertically, for a stronger final product.

Cut the drywall using a utility knife and a t-square. You don't need to cut hard to get drywall the shape you want. When cutting, score a line through the face-paper (the front side of the drywall). Next, break the drywall by snapping away from the cut.

• You may need to cut the drywall into a less regular shape, to fit it around an air vent, for example. Use the same process as you regularly would, taking care to cut off little by little instead of making one big cut. Remember, you can always cut off more later, but you can't put more back on after cutting too much off.

Start on the walls once the ceiling is completed.^[6] Again, the drywall should be hung horizontally, which might sound more difficult than vertically, but is not. Hang the top piece first. Butt it up to the piece on the ceiling and nail or screw. Again, this will probably take more than one person to do, but if you've got muscle is relatively easy to do alone if no helpers are available.

• Remember to start from one (top) corner and work on only one row before moving on to the next row.
• Butt the bottom sheets up to the top pieces on the walls that you have just hung. They should be close to one another, but a little space is okay: You are going to tape and mud the joints later, so you do not have to worry about getting a perfect specimen right away.

Continue around the room until complete. Work slowly and steadily, minimizing mistakes and making sure to plan. While hanging sheetrock, remember to:

• Glue studs before hoisting the sheetrock into place
• Gun in four or five screws on a stud, hitting each stud that's behind the sheetrock. (To drive screws with the gun running, don't be gentle — punch them in.)
• Cut around windows, doors, fixtures, and other obstacles. If you have an obstacle that you don't know how to work around, consult a contractor.
• Check all the screws or nails with a drywall knife to make sure none are sticking out. (Every one you miss will have to be driven in or removed when you're taping, which will make you very grouchy.)

Read up on how to finish drywall. Finishing drywall involves covering the entire sheetrock with a thin layer of joint compound, and then scraping it away, to give the sheetrock an even effect. This process is essential for a professional-looking job.

• Remember—it's always easier to add more compound than to remove it if you put on too much.^[7]
