3 Unit 58 Interior Wall and Ceiling Finish Gypsum board is fastened directly to wood or metal framing members and provides a smooth surface for paint or wallcoverings.

4 Unit 58 Interior Wall and Ceiling Finish Gypsum boards have different edge shapes depending on their purpose.

5 Unit 58 Interior Wall and Ceiling Finish Gypsum board is cut by scoring it on the face side and then snapping off the waste piece.

6 Unit 58 Interior Wall and Ceiling Finish Jagged gypsum board edges can be smoothed with a serrated-blade forming tool.

7 Unit 58 Interior Wall and Ceiling Finish In single-ply application, only one layer of gypsum board is used.

8 Unit 58 Interior Wall and Ceiling Finish In double-ply application, an adhesive is used to bond the second layer of gypsum board to the base layer. The second layer runs at a right angle to the base layer.

9 Unit 58 Interior Wall and Ceiling Finish A metal foot lift is used to raise a gypsum board wall panel up tightly against the ceiling. The space below the panel is covered by base molding.

10 Unit 58 Interior Wall and Ceiling Finish Nails may be used to fasten gypsum board to wood framing members. Small-headed nails are used with predecorated panels.

11 Unit 58 Interior Wall and Ceiling Finish Nails must be driven properly to ensure a solid connection between the gypsum board and wood framing member. Nails driven too deeply, or at an angle, will cut through the face covering.

12 Unit 58 Interior Wall and Ceiling Finish Loose nails are caused by a poor fit of the gypsum board to the framing surface or by nails missing the framing members.

13 Unit 58 Interior Wall and Ceiling Finish The proper single- nailing pattern ensures a sound connection between the gypsum board and wood framing member. Nailing should begin at the center of the panel and move outward.

14 Unit 58 Interior Wall and Ceiling Finish When double-nailing gypsum board, the second set of nails may be driven after the first set is driven across the entire panel, or the second set of nails in each row may be driven after the first set in each row is driven. Nailing should begin at the center of the panel and move outward.

15 Unit 58 Interior Wall and Ceiling Finish Screws may be used to fasten gypsum board to metal or wood framing members. A drywall screwdriver is used to drive the screws.

16 Unit 58 Interior Wall and Ceiling Finish Stud adhesive is used with screws or nails to fasten single-ply gypsum board to wood or metal framing members.

17 Unit 58 Interior Wall and Ceiling Finish Gypsum board must be properly finished to ensure a smooth and even surface.

18 Unit 58 Interior Wall and Ceiling Finish Metal corner beads reinforce outside corners of gypsum board.

19 Unit 58 Interior Wall and Ceiling Finish Molding is used to cover joints and corners of predecorated gypsum board.

20 Unit 58 Interior Wall and Ceiling Finish Grooved softwood-veneer plywood wall panels create pleasant shadow lines.

21 Unit 58 Interior Wall and Ceiling Finish Wall paneling may have rabbeted or beveled edges, forming channel or V-joints respectively.

22 Unit 58 Interior Wall and Ceiling Finish Plywood panels are stacked with wood strips between them for preconditioning to room temperature.

23 Unit 58 Interior Wall and Ceiling Finish Furring strips are installed over existing uneven walls to provide a smooth and even wall surface for plywood or hardboard panels.

24 Unit 58 Interior Wall and Ceiling Finish Panels can be positioned so that a continuous joint occurs on each side of the door or so joints break over the openings.

25 Unit 58 Interior Wall and Ceiling Finish Holes for electrical outlets and other openings must be laid out before the panel is set in place. The openings may be cut before or after the panel is positioned using a cutout saw.

26 Unit 58 Interior Wall and Ceiling Finish The item requiring an openingin this case an electrical boxis used as a pattern for marking a panel opening.

27 Unit 58 Interior Wall and Ceiling Finish When installing wall panels over stud walls, the edges of the panels must fall over the centers of the studs.

28 Unit 58 Interior Wall and Ceiling Finish Base and ceiling moldings eliminate the need to scribe the top and bottom panel.

29 Unit 58 Interior Wall and Ceiling Finish Molding is often used to cover the inside and outside corners of interior paneling.

30 Unit 58 Interior Wall and Ceiling Finish A panel must be carefully scribed to the other wall when no molding covers the inside corner.

31 Unit 58 Interior Wall and Ceiling Finish Wall panels may be mitered if molding is not used on an outside corner.

32 Unit 58 Interior Wall and Ceiling Finish Flush application of panels on outside corners is easier than mitering and panel edges are less susceptible to damage.

33 Unit 58 Interior Wall and Ceiling Finish Nails are less noticeable when driven along the bevel or into the grooves of a panel.

34 Unit 58 Interior Wall and Ceiling Finish Adhesive is applied in 3 long beads, 6 apart, at intermediate studs or at furring strips behind the panel.

35 Unit 58 Interior Wall and Ceiling Finish A wall panel is pressed into place after the adhesive has been applied.

36 Unit 58 Interior Wall and Ceiling Finish After the panel has been pressed against the adhesive, it is grasped at the bottom along both edges and slowly pulled away from the stud. The panel is then pressed back into position after 2 min.

37 Unit 58 Interior Wall and Ceiling Finish Solid board paneling may be applied horizontally.

38 Unit 58 Interior Wall and Ceiling Finish When installing board- on-board wall paneling, drive an 8d nail at the center of the underboard. The top boards should overlap the underboard a minimum of 1. Fasten the top board with two 10d nails. Make sure the nails clear the underboard to allow for expansion and contraction.

39 Unit 58 Interior Wall and Ceiling Finish When installing board-and-batten wall paneling, drive an 8d nail at the center of the underboard. The underboards are spaced approximately 1/2 apart. Drive a 10d nail through the center of the batten.

40 Unit 58 Interior Wall and Ceiling Finish When installing tongue-and-groove wall paneling, 4 and 6 widths can be blind-nailed with 6d finish nails driven at a 45° angle. This method eliminates the need to countersink and putty face nails.

41 Unit 58 Interior Wall and Ceiling Finish When installing channel-rustic solid board paneling up to 6 wide, one face nail is adequate to secure the board. Widths over 8 require a face nail at the center of each board.

42 Unit 58 Interior Wall and Ceiling Finish Blocking must be placed in a stud wall to provide a nailing base for vertical board paneling.

43 Unit 58 Interior Wall and Ceiling Finish Prior to installation, solid board paneling is arranged along the wall so wood grain and other features can be matched to each other.

44 Unit 58 Interior Wall and Ceiling Finish When tapping a board panel into place, use a piece of material with a grooved edge against the board to avoid damaging the edge.

45 Unit 58 Interior Wall and Ceiling Finish Plastic laminate wall panels are available with an imitation wood grain finish.

46 Unit 58 Interior Wall and Ceiling Finish Suspended tile ceiling systems are frequently used in commercial construction.

47 Unit 58 Interior Wall and Ceiling Finish Ceiling tile with tongue-and-groove edges are stapled through the wide flanges into the furring strips.

48 Unit 58 Interior Wall and Ceiling Finish For a ceiling with even-foot dimensions, the center tiles are positioned at each side of the centerlines.

49 Unit 58 Interior Wall and Ceiling Finish For a ceiling with odd- foot dimensions, the center tiles are positioned so the centerlines align with the middle of the tiles.

50 Unit 58 Interior Wall and Ceiling Finish Border tiles on opposite sides of the ceiling should be the same width, and should be at least 6 wide.

51 Unit 58 Interior Wall and Ceiling Finish Suspended ceilings are often installed in commercial buildings.

52 Unit 58 Interior Wall and Ceiling Finish Recessed lighting can be used with suspended ceilings. Plumbing, lighting, and ventilation fixtures must be properly secured to structural members above a suspended ceiling.

53 Unit 58 Interior Wall and Ceiling Finish A laser level is commonly used to establish the suspended ceiling height at several locations along the wall.

54 Unit 58 Interior Wall and Ceiling Finish A suspended ceiling framework consists of main runners and cross tees, which are supported by hanger wires. Ceiling tile panels are supported by the runners and cross tees.
