S-310 Dry to Touch >15 minutes (tacky to
touch with no transfer to fingers)
S-240** Set in wet
Approximately 10-20 minutes
NOTE: The amount of open time will vary according to job conditions- temperature, humidity, air flow and
type of substrate.
** It is necessary to smooth out the adhesive trowel ridges using a 3/16" (4.8 mm) nap paint roller. The
purpose of this is to create a uniform application of the adhesive.
Layout & Fitting
Layout:
Whenever possible, plan the layout so that the joints in the planks do not fall on top of joints or seams in the
existing substrate. The end joints of the planks should be staggered a minimum of 6" apart. Do not install
over expansion joints.
Determine which direction the planks will run. Find the center of each of the end walls (the walls
perpendicular to the long dimension of the planks) and place a pencil mark on the floor. Connect these
points by striking a chalk line down the center of the room. Do a dry layout of planks from the center line to
the wall running parallel to the long direction of the planks to determine the width of the last row of planks.
Fig. 1 Dry layout to determine width of border plank.
Avoid having border pieces less than 2" (5.1cm) wide for the 4" (10.2cm) wide planks and less than 3"
(7.6cm) wide for the 6" (15.2cm) wide planks. If you find the border planks will be less than 1/2 the width of
the plank, the center starting line should be shifted a distance equal to 1/2 the plank width. This will
"balance" the room and provide for a larger cut piece at the wall.

nstallation Methods
Procedure:
Armstrong S-288 Flooring Adhesive
Apply S-288 adhesive to 1/2 of the area at a time so that you can start the installation along the center
starting line. Begin laying planks along the center starting line and install row by row including the cut
pieces at the perimeter until 1/2 of the installation is complete. Stagger the end joints by at least 6 inches
(15.2 cm). Apply adhesive to the remaining portion of the room, allow the adhesive to dry-to-touch and
complete the installation of planks in similar fashion.
