Hang Drywall on Basement Walls

Basement walls transform from raw framing to livable space the day you hang drywall. The work is methodical rather than difficult — measure, cut, screw, repeat — but the weight of the sheets and the precision required at corners and electrical boxes separate clean installations from ones that telegraph every mistake through three coats of paint. Get the hanging right and the taping becomes straightforward. Rush the layout or skimp on fasteners and you'll spend weeks trying to hide waves and pops that should never have existed. Most basements use half-inch drywall on 16-inch-center studs, though five-eighths-inch adds soundproofing if you're building a media room or separating living space from utility areas. The key decision is whether to run sheets horizontally or vertically. Horizontal creates fewer seams on 8-foot walls and makes taping easier, but requires a helper or a good panel lift. Vertical works solo and suits 9-foot walls, but adds linear feet of seams to finish. Either way, the goal is the same: flat, secure panels that disappear once painted.

1. Plan Before You Hang. Snap chalk lines on the floor where each stud meets the bottom plate, extending the line 6 inches out from the wall. Measure your wall sections and sketch which sheets go where, minimizing seams and avoiding joints that align with door or window corners. Plan to stagger seams between rows by at least one stud bay.
2. Score and Snap Clean. Measure the height or width needed, mark both edges of the sheet, then score the face paper with a utility knife against a straight edge. Snap the sheet backward to break the gypsum core, then cut the back paper. Smooth any rough edges with a rasp or the blade.
3. Position with Precision. If hanging horizontally, place the top sheet first so the tapered edge meets the ceiling where you'll tape later. Lift the panel into position — use a panel lift or a helper — and check that edges land on stud centers. Adjust before driving any screws.
4. Dimple, Don't Destroy. Drive 1¼-inch coarse-thread drywall screws every 12 inches along each stud, starting from the center and working outward. Dimple each screw head just below the surface without breaking the paper. Keep screws at least half an inch from panel edges.
5. Cut Outlets First. Measure from the last installed panel edge to each side of the box, and from floor or ceiling to top and bottom. Transfer measurements to the new sheet and cut the opening with a drywall saw or router. Test-fit before final installation.
6. Complete the Coverage. Work across the wall, butting edges tight and maintaining your stagger pattern. At inside corners, run the first panel into the corner and let the adjacent panel overlap it. Outside corners get metal corner bead screwed every 9 inches after both panels are up.
7. Three Coats to Smooth. Apply a bed coat of joint compound along each seam, press paper tape into it with a 6-inch knife, then cover with a thin skim coat. Fill screw dimples. Let dry completely, sand lightly, then apply second and third coats with progressively wider knives to feather edges.
8. Sand Smooth and Prime. Once the final coat dries fully, sand all joints and fasteners with 120-grit paper on a pole sander. Wipe dust with a damp cloth, then apply drywall primer to seal the surface and even out texture between compound and paper before painting.
