PLANNING THE JOB Achieving a smooth Selecting Materials 1 USG Sheetrock® Brand UltraLight Panels are innovative lightweight gypsum wallboard panels for use on walls and ceilings. Their high strength-toweight ratio and superior sag resistance eliminate the need for traditional 1/2" sag-resistant ceiling panels. interior finish with USG Sheetrock® Brand Gypsum Panels is easy with proper planning from the start.
PLANNING THE JOB Application Products Horizontal or Vertical Application Type W Bugle Head Screws attach singlelayer gypsum panels to wood framing. Screws provide greater holding power than wallboard nails, minimize popping and help prevent damage to the panels. 1 5 USG Sheetrock® Brand All Panels may be applied horizontally (long dimension across studs or joists) or vertically (long dimension parallel to studs or joists).

PLANNING THE JOB 3 CUTOUTS For openings such as an electrical outlet or switch box, measure across from the point where the side edge of the panel will rest to the near and far sides of the installed box. Then measure from the point where the top or the bottom edge of the panel will fall to the top and bottom of the box. 4 FRAMING 5 NAIL ATTACHMENT PANEL 4 PG.10 PANEL 7 Trace the outline of the electrical box at the appropriate position on the gypsum panel.
ATTACHING THE PANELS TIP On 3/8", 1/2" and 5/8" thick panels, use 1-1/4" Type W Bugle Head Screws for superior holding power and high resistance to popping due to wood shrinkage. OR PG 9. 8 CEILINGS Apply ceilings first. Because panels are difficult to maneuver over one’s head, it’s best to have a helper or two. Fasten panels to all joists and perimeter framing. Space nails maximum 7" apart along framing, screws 12" apart, starting in the center of the panel and working toward the perimeter.
FINISHING THE PANELS 10 CORNERS Method 1 — USG Sheetrock® Brand Dur-A-Bead® Corner Bead Reinforcement Using USG Sheetrock® Brand Dur-A-Bead® Corner Bead reinforcement, apply it to all exterior corners of walls, soffits and window returns. Hold bead firmly against corner and nail bead through small holes every 9" on each flange. Make sure that nails penetrate framing members. Drive all nails below nose of corner bead and tightly into flange so joint compound will cover smoothly and evenly.
FINISHING THE PANELS 11 FIRST COAT, BUTT AND TAPERED JOINTS For best results, joint compound should be thinned slightly with water for easier application. Add water in small increments (for 1 gal. of compound, add water in 2 oz. increments.) Start with butt joints. Apply an even coat of thinned joint compound for the length of the joint with a 5" finishing knife. To reinforce tapered joints, follow same procedure. Tape should overlap tape applied to butt joints.
FINISHING THE PANELS 13 FIRST COAT, FASTENERS 14 FIRST COAT, OUTSIDE CORNERS AND For each fastener depression, METAL TRIM apply joint compound with 5" knife. Holding the blade almost flush with the panel, draw the joint compound across a fastener head and the dimple surrounding it. Apply joint compound with 8" knife onto one flange of the corner bead. Work down the entire length of the bead.
FINISHING THE PANELS 17 SECOND COAT, OUTSIDE CORNERS AND METAL TRIM Allow first coat to dry overnight (drying time may vary, depending on temperature, humidity and jobsite conditions). Apply second coat with 8" knife, feathering slightly beyond first coat. TIPS When applying earlier coats, minor depressions and grooves were not a problem. However, do not leave any during the application of this final coat or they will mar the finished surface. Do not sand unless it is necessary.
FINISHING THE PANELS Wet Sanding Decorating the Panels When only minimal sanding is needed, try wet sanding with a sponge. It eliminates dust and does not scuff the surface paper. Use a smallcelled polyurethane sponge similar in appearance to carpet padding. Saturate sponge and wring to prevent dripping. Rub joints to remove high spots, using as few strokes as possible. Clean the sponge frequently during use. Wear a dust mask if excessive dust is produced and the area cannot be ventilated.
