INSTALL CEILING PANELS

Installing Panels

• Lift 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 lift 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.

Cutting “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 ﬁtting 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 attached 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 www.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. After installing material, wash with warm water and mild soap. Wash work clothes separately from other clothing. Rinse

washer thoroughly.
