STEP : INSTALL CEILING PANELS
Installing Panels
• Lit panel at angle up through the grid; drop into place (A).
TIP: If there’s an obstruction in the area where you are inserting a ceiling tile, you may
need to lit the ceiling tile through an adjacent opening and gently move it across the
back of the grid into place.
• Trim border panels using a straight edge; panels should be cut face side up (B).
For tegular tiles, you will need to cut the edge that’s resting on the wall molding to
allow it to lay flat.
Cuting “Tegular”/“Recessed Grid” ceiling border panels
• Trim tegular edge border panels to the same dimensions as for flat panels. The
tegular edge detail must now be cut into the panel.
• Set the panel into the grid. Draw a light pencil line on the panel using the wall
molding as a guide (C).
• Remove the panel. Use a sharp utility knife and straight edge to cut halfway
through the panel from the face side along the pencil line (D).
• Lay the utility knife on its side next to the panel and, with the panel face up, cut in
at blade height for a reveal cut (E).
• Remove the cut edge. If the cut edge of the panel is visible, paint with a flat white
latex paint.
• Fit the panel into the grid.

Precautionary Measures: During the installation, be certain that the work site is well
ventilated and avoid breathing dust. Avoid contact with skin or eyes. Wear long-sleeve,
loose fiting clothes, gloves, and eye protection. Cut and trim with knife, razor, or
hand saw. Do not cut with power equipment unless the equipment has an atached
dust collector. The work site air quality should be assessed and if conditions require, a
NIOSH approved respirator should be worn.
This product may contain small levels of crystalline silica. Exposures to respirable
crystalline silica are not anticipated based on industrial hygiene testing on
workers installing acoustical ceiling panels for an 8-hour work day and are not
expected during the normal use of this product. Specific worksite conditions must
be taken into consideration to determine if workplace industrial hygiene testing is
necessary. Prolonged and repeated exposure to airborne crystalline silica can result
in lung disease and/or lung cancer. Panels do not release respirable dust in their
installed state. For additional information, refer to the Safety Data Sheet at
armstrongceilings.com
First Aid Measures: If eye or skin contact occurs, flush with plenty of water for at least
15 minutes and remove contaminated clothing. Ater installing material, wash with
warm water and mild soap. Wash work clothes separately from other clothing. Rinse
washer thoroughly.
