The suspended ceiling method uses ceiling tiles hung from a grid called furring. The furring supports the tiles and keeps them from succumbing to gravity and falling downward. Builders should adhere tiles to the furring with adhesive as well as nails or staples. However, time and/or water damage often leads to tiles sagging from the furring. Another contributing factor of ceiling tile failure is that builders sometimes skip steps and merely glue the tiles. Glue alone does not adequately hold the tiles to the furring. When ceiling tiles begin to sag, glue and staple them to the furring or install external furring. Gluing and stapling will maintain the original look of the ceiling.

Staple Onto Furring

Step 1

Locate the furring onto which the sagging tiles originally adhered.

Step 2

Apply ceiling tile adhesive between each sagging tile and its furring with a putty knife.

Step 3

Hold a sagging tile down and staple to the furring with a staple gun.

Step 4

Continue until all tiles are reattached to the furring.

External Furring

Step 1

Cut a two-by-four board to fit the width of the ceiling.

Step 2

Paint or finish the board as desired, and allow it to dry.

Step 3

Locate the furring under the sagging tiles, and apply ceiling tile adhesive to the furring.

Step 4

Screw the two-by-four securely down the seam of the sagging tiles using 3-inch screws.
