Using your map and taking into account the variables above, snap two chalk lines along your ceiling’s
midpoints, forming a cross in the center of your ceiling. Keep in mind that ceilings are rarely square
and chalk lines may need to be adjusted.
Break Out the Adhesive
Apply a perimeter and center bead of ceiling tile adhesive to the backside of your ceiling tile (1/8” to
3/16” is a good bead width). For a at tile, a bead around the edge and a simple center pattern is all
that is required. For a three-dimensional tile, an additional bead near the formed features will ensure
a good bond.
As you are applying your adhesive, remember – it isn’t how much adhesive you use, but that you use
the right amount of adhesive in the right places.
Position your ceiling tile about 1/4” oset from your chalk lines and lightly press it to the ceiling. Then
slide it into place against the chalk lines, allowing the adhesive to spread just a bit. Press and rub
rmly over the glued areas, smoothing out any bumps in the glue and seating the tile rmly into place.
Once your rst ceiling tile is installed, begin placing adjacent tiles. Your second ceiling tile should
be placed directly against the rst. Seams between tiles may vary slightly, so do not butt the tiles
together with force, simply slide them into place. All joints will be covered with decorative or smooth
strips in the nal phase of installation; do not worry about any small gaps between your tiles.
Border Tiles
In all likelihood, your ceiling will have some less than full-size areas, usually around the perimeter of
your room. Border tiles have been designed with a minimum relief pattern that lends itself to trimming
and installing in these smaller areas.
Simply measure from the edge of an installed tile to the wall and cut your border tiles to size with
scissors or snips. Apply a perimeter bead of ceiling tile adhesive to the backside of the trimmed tile.
Position it with the cut edge toward the wall, about 1/4” oset from its nal position and lightly press it
to the ceiling. Then slide it into place, allowing the adhesive to spread just a bit. Press and rub rmly
over the glued areas, smoothing out any bumps in the glue and seating the tile rmly into place.
Repeat with your remaining border tiles, proceeding from one adjacent tile to the next until your
border is complete.
When nished, clean tools with warm water and paper towels while the ceiling tile adhesive is still
wet. Dried material can be scraped or chipped o if needed.
