general
• The permanent HVAC system must be turned on and set to a minimum
of 68°F (20°C) for a minimum of 72 hours prior to, during, and after
installation. After the installation, the maximum temperature should
not exceed 100°F (38°C).
• Only L910 Adhesive (available from walltalkers ® ) should be used.
• Use a 1/16" x 1/16" x 1/16" square notch trowel only.
• Ensure the tac·wall has been acclimated to the installation area for
a minimum of 24 hours prior to installation.
• Material should always be visually inspected prior to installation; any
material installed with visual defects will not be considered a legitimate
claim as it pertains to labor cost.
• Wall must be smooth, rigid, flat, dry, clean, and free of all foreign
materials such as dust, paint, grease, oils, solvents, sealers, and old
adhesive residue.
• All tac·wall must be from the same lot for color matching of butted
seams/same room wall installations.
PLEASE NOTE: Factory edges cannot always be butted together due
to shipping and because the factory edges are not always straight.
• Apply the tac·wall with burlap (jute) backing to the wall.
• Perform an adhesive bond test prior to installation to ensure an
adequate bond.
• tac·wall will expand slightly in width and shrink slightly in length
when placed into the adhesive. Proper installation procedures will
compensate for this.
• Do not reverse sheets for seaming.
• Install one sheet at a time.
• Install all cuts and rolls in consecutive sequence.
• Ensure that all recommendations for jobsite conditions are met prior
to beginning the installation. Once the installation is started, you have
accepted those conditions.
1. application possibilities
tac·wall can be applied in two different ways:
• Installed as a notice board or a panel for furniture
workstations/partitions.
• Installed to cover entire walls/parts of walls.

CUTTING SHEETS
Unroll tac·wall and cut to the length, adding 2" to 3" of overlap,
preferably 24 hours prior to installation. Lay sheets flat and allow
them to acclimate at a minimum temperature of 68°F (20°C). Back
roll sheets once in reverse direction to release roll stretch and end
curl. Tac·wall shrinks lengthwise (1% at maximum) and expands
slightly widthwise.
CHOICE OF ADHESIVE
Apply L910, a SBR solvent free adhesive, with a 1/16" x 1/16" x 1/16"
square notched trowel. When using a press, the use of high-quality
polyvinyl acetate dispersion adhesive may be used in a double-stick
method.
ADHERING & PRESSING
Adhere the tac·wall onto the surface of a backing board and press
in firmly with a hand roller, or with a press. Using a press enables a
number of tac·wall covered sheets to be pressed simultaneously.
SAWING/MILLING TO SIZE
Test the tac·wall for proper adhesion then saw or mill to size.
NOTE: Always use sharp tools for best results.
FINISHING OFF EDGES
The edges can be finished by:
• Fitting a frame around the edge
• Beveling the edges
• Milling to desired edge
• Cutting the edges straight
BACKING/COUNTER-BALANCING
Standard recommendation: For proper counter-balancing, the back
of the board should also be covered with the same material as that
pasted on the front, in the same direction, with the same type of
adhesive and, if possible, at the same time. Depending on the
thickness, symmetrical construction and rigidity of the surface
(MDF, plywood, etc.) other materials can also be used, such as
foil, laminates, impregnated paper, or marine lacquer sprays. We
recommend conducting a test installation if you have not worked
with the materials before.
WALL CONDITIONS
Tac·wall can be adhered directly onto walls, which are compression
and deformation resistant, and permanently dry, smooth, and clean.
Fill in crevices on non-smooth walls and sand. Lightly sand off any
existing adhesive residue. Be sure the walls being covered are clean
and free of dust. This is to ensure proper bonding with the adhesive.
It is always best to conduct an adhesive bond test prior to installation.
JOB CONDITIONS
Cut sheets of tac·wall to required length, adding 2" to 3" extra,
preferably 24 hours prior to installation. Lay sheets flat and allow
them to acclimate with the permanent HVAC system set at a minimum
of 68°F (20°C) for at least 72 hours prior to, during, and after the
installation. If possible, store sheets in the room they are to be installed.
Tac·wall shrinks lengthwise (1% at maximum) and expands slightly
widthwise.
CUTTING TO SIZE
For the best results, remove factory edge from both sides of the first
panel with a seam and strip cutter (available from walltalkers). A
straight edge, utility knife, or hooked blade knife may also be used to
trim the factory edge. Trim off approximately 1/2". With a utility knife,
score material about one third of the material thickness. Then, with the
hooked blade knife, cut along the score line, holding the knife at an
angle to slightly undercut the edge. For best results,
do not use sheets less than 39" wide.
If subsequent sheets are to be installed, trace cut the
edges with the seam and strip cutter. Follow instructions
provided with the tool and/or request a copy of the
tac·wall installation video from your distributor.
