The Drywaller’s Toolkit: 12 Essential Tools for a Perfect Job 👍

The earliest wall finish was probably some form of mud, a crude plaster smeared over stone or stuffed into the gaps between logs. Today, chances are the walls in your home are sheathed in drywall—panels made of gypsum sandwiched in heavy paper. It’s also called wallboard and Sheetrock (or just “rock”), a trade name of the U.S. Gypsum Corp. Easy to work with, nonflammable and durable, drywall has largely supplanted lath and plaster for sheathing interior surfaces. Sheets of drywall are screwed or nailed into place, the joints are bridged with a special paper drywall tape, and then all the cavities are filled with joint compound, universally known as “mud.”
Hanging drywall is easy. Finishing joints is a bit more work, but it’s well within the do-it-yourselfer’s reach. You can’t do it without the proper tools, however. A good cordless drill-driver is indispensable. Joint work requires special knives you’ll use to embed tape and build up the three mud layers so that joints are all but invisible. Take a look at the tools that follow. Most are inexpensive, and all provide the ineffable pleasure that comes from having the right tool for the job.

Tape Measure

The first skill of drywalling is measuring accurately: “Measure twice and cut once,” as the old saying goes. This 25-foot measure is about right for most jobs; anything much longer can be cumbersome to handle.

Chalk Line

Once you’ve marked measurements at either end of a drywall panel, snap a line between them with a chalk line. Easy does it—this is not archery. Pull the taut line an inch or three above the face of the drywall and release.

Utility Knife

When you score drywall, there’s no need to cut through the whole sheet. One or two firm passes along a straightedge are enough to score the paper surface. If you sharply snap the scored sheet over the edge of your work table, or just stand it up and smack it on the back with your fist, the gypsum core will snap. Then all you need to do is cut through the paper backing to completely sever the section. Keep plenty of replacement blades on hand; a sharp blade saves you a lot of work and ensures clean cuts.

Cordless Drill-Driver

Screwing drywall into place is the only way to go. And the best way to drive screws is with a cordless drill-driver. If you don’t have one yet, here’s your excuse to buy one. It’s probably the most versatile power tool you can have, and for most homeowners, the first power tool to buy.

Magnetic Driver Bit With Sleeve

A magnetized bit is essential to hold screws as you drive them. The magnetic bit grips the screw, while the retractable sleeve reduces stripping and prevents wobbling.

6-inch Taping Knife

The drywalling workhorse is the 6-inch knife. Use this versatile tool to fill nail or screw dimples and to bed the tape in the first layer of joint compound. It’s also handy for repairing smallish holes in drywall, say, anything smaller than a fist. You’ll do a lot of work with this tool, so pick a good one.

10-inch Joint Knife

Once you’ve sanded your first coat of mud, use a 10-inch knife to feather out the second coat. (A professional can actually finish a joint with this tool.) This broad knife greatly minimizes sanding—something you’ll come to appreciate after you’ve finished a few joints.

18-inch Joint Knife

You may have to go to a specialty supplier for an 18-inch joint knife, but it will be worth the search. It takes a bit of practice and a strong wrist to spread a thin layer of an 18-inch swath of mud, but the resul
