Surface Mount Ceiling Panels

8. ADHESIVE INSTALLATION CONSIDERATIONS

8.1 Area Preparation:

Surfaces must be dry and free of dust, grease, oil, dirt or any other material that may deter adhesion. If the paint is ﬂaking or

peeling it must be removed. Existing ﬁnish paint must be well-bonded and not ﬂaking or peeling.

8.2 Painted Surfaces:

Avoid applying to a newly painted ceiling. Glossy painted surfaces must be abraded. For painted or sealed surfaces, install a

small test area and observe after 12 hours. For plaster ceilings, plaster must be painted, non-chipping, and smooth.

8.3 Surface Flatness:

To ensure a ﬁnished installation that is level, it is recommended that the ceiling surface for attachment be free of irregularities

and be level within 1/4" in 12'.

9. INSTALLING PANELS WITH ADHESIVE TO DRYWALL/CONCRETE/PLASTER

9.1 For drywall, concrete, and plaster installations with AcoustAfﬁx

™

panels, reference the follow sections. The Titebond

GREENchoice Acoustical Ceiling Tile Adhesive provides a secure bond and does not require any supplemental mechanical

attachment as long as these instructions are followed.

9.2 Panels should have at least a 1/4"-3/8" reveal between edges. This will help alleviate slight differences in the levelness of

adjacent panel faces.

9.3 Adhesive should be applied per the following guidelines:

• Your glue lines should be 20" long and 4" wide (illus. 9.3).

• Maximum distance from glue line end to panel edge: 2"

• Maximum distance from glue center line to panel edge: 6"

• Maximum distance between center line of the glue rows: 18"

9.4 Utilizing the trowel, ensure that the adhesive is uniformly spread to cover

your speciﬁed area.

9.5 Once in position, push the panel against the ceiling applying even hand

pressure to the board where the adhesive is located in the center ﬁrst, followed

immediately by the edges of the panel. By attaching the center ﬁrst, you can

still pivot the panel slightly left or right before adhering the edges. This ensures

that the panel can be aligned correctly ﬁrst before the edges are solidiﬁed into

place. Avoid excessive pressure to minimize panel ﬂexing that will disturb the

previously pressed areas of adhesive and result in release of the adhesive.

9.6 Any slight adjustments to the panel placement should be done immediately to not weaken the adhesive bond once it has

started to set. Once the panel is evenly pressed into position, the adhesive should provide an immediate bond to hold the panel

in place while the adhesive sets.

9.7 Press a sponge ﬂoat across all areas of the panel where glue was applied to ensure all glue spots and lines are properly

compressed and adhere to the deck. Lastly, measure adjacent panel edges to check levelness as panels are installed; the

levelness of the ﬁnish face of adjacent panels should be within 1/8" to ensure a satisfactory visual

9.8 For wall installations, follow steps 9.1 – 9.6 and apply the same methods in the vertical. Use a square or straight edge to

conﬁrm that the face of the panels are ﬂush within 1/8" to ensure a satisfactory visual. The bottom edge of the panel should

be at least 6' from the ﬂoor to avoid damage.

NOTE: Panel creep may occur as the glue is setting. Panels should creep no more than 1/8" during installations.
