Details: | Reattaching Loose Or Fallen Tin Ceiling Panels REATTACHING LOOSE OR FALLEN TIN CEILING PANELS PART 1---GENERAL 1.01 SUMMARY A. This procedure includes guidance on resecuring tin ceiling panels that have worked loose or have fallen. B. Metal ceiling panels are typically 2'-0" x 8'-0" and are nailed to wood furring strips which are, in turn, nailed to the ceiling joists of an existing ceiling. PART 2---PRODUCTS 2.01 MANUFACTURERS NOTE: The following manufactuers listed below are potential sources for replacement panels, where existing panels can not be reattached. A. W.F. Norman Corporation P.O. Box 323 Nevada, MO 64772 800/641-4038 B. Classic Ceilings 902 E. Commonwealth Ave. Fullerton, CA 92631 800/992-8700 C. Entol Industries, Inc. 8180 NW 36th Ave. Miami, FL 33147 800/368-6555 2.02 MATERIALS A. 1" long flat head nails as required B. 3" long flat head nails or 2-1/2" drywall screws as required C. Wood shims as required D. Glazing compound or latex caulk 2.03 EQUIPMENT A. Hammer and/or screwgun B. Heavy gloves and protective gear C. Scaffolding/working platforms D. Ladders PART 3---EXECUTION 3.01 EXAMINATION NOTE: BEFORE RESECURING ANY CEILING PANELS OR FURRING STRIPS, IT MAY BE USEFUL TO UNDERSTAND HOW A METAL CEILING IS ASSEMBLED. A. Tin ceiling panels are typically 2'-0" x 8'-0" and are attached to an existing ceiling by nailing the panels to 1"x2" furring strips. B. 1"x2" furring strips are typically attached to an existing ceiling using 3" flat head nails or 2-1/2" drywall screws. NOTE: FURRING STRIPS MAY BE SHIMMED AT VARIOUS LOCATIONS TO ENSURE THAT THE CEILING WILL BE AS LEVEL AS POSSIBLE. 1. Furring strips are first nailed perpendicular to the ceiling joists and spaced 24" on center. 2. Additional 1"x2" furring strips are then installed parallel with the ceiling joists (and perpendicular to the furring strips installed in #1 above) and spaced 8'-0" on center to provide nailers where the ceiling panels overlap. These secondary furring strips are typically 22" long (if 2" furring is used). 3. Finally, intermediate furring strips are nailed perpendicular to the ceiling joists (as in #1 above) to make the overall spacing of furring strips in this direction 12" on center. These intermediate strips are typically 94" long (if 2" furring is used). 4. 2'-0" x 8'-0" ceiling panels are then nailed to the furring strips in an overlapping position using 1" flat head nails. 3.02 ERECTION, INSTALLATION, APPLICATION A. Check for loose or missing nails used to attach the ceiling panels to the furring strips. 1. Hammer nails securely back in place as required. 2. Replace missing nails with 1" flat head nails. Nail at beads/buttons along furring strips as required to resecure the panel. B. For panels that have fallen: Check to see that the furring strips are level and secure; check to see that wood shims are still securely in place. 1. Shim behind the furring strips as needed before nailing to level it with the rest of the strips. a. Use a good straightedge to align the strips. b. Use the claw of a hammer to pull high strips down into the same plane as the lower strips. c. Install shims between the furring and the ceiling as required. 2. When the strip is in line, drive all nails home using 3" flat head nails. 3. Reattach tin panel to furring strips as described above in Section A. a. Drive the nails to one side of the bead. b. To line up the next sheet, overlap the beads with the previous sheet (the way a ball and socket fit). Nail directly through the beads on the overlapping sheet. C. For gaps where edges of panels overlap: 1. Hold the flat head of a 3" nail against the edge of the metal and gently tap the tip of the nail with a hammer. 2. Fill any remaining gaps with glazing compound or latex caulk. END OF SECTION |
