Installation Guide
10) After the rst row has set up, apply the remaining tiles according to the
pattern or layout you desire. Use adhesive and methods described above for
remaining rows.
11) When installing the top row, install
as you have been until you get to the
last tile in the corner. If tiles butt against
your ceiling, when installing the last tile,
remove anges from the bottom and
side (image Q). Lay tile into place. Apply
pressure to ensure tile is ush with
others. Use a recommended silicone
sealer—as previously described—in
joints to ensure a water-tight installation,
if applicable.
5) Cut panels for outlets and light switches. Measure and mark the borders
where the opening will be with a marker. Drill a ½” to 1” hole using a drill in
a corner of the cut-out section (image F). Use a jigsaw to cut the remaining
opening, following your tracing (image G).
6) If installing into a corner, the vertical ange must be cut o to allow for a
plumb edge against the substrate (image H). The bottom ange should
also be cut o of tiles when placing them on the ground. This will allow for
a level edge on bottom (image I).
7) Do not attach accessories like coat hooks, light ttings, mirrors, etc.
directly to the tiles. Drill holes through the tiles and use suitable anchors
to attach the accessories securely into the framing behind. Seal per
instructions using DAP Kwik Seal Ultra.

READ this entire installation guide before beginning your installation.
ACP is not responsible and will not be held liable for project failures
if installation guidelines are not followed. ACP recommends that you
install these tiles over an existing substrate to ensure proper
structural integrity.
DumaWall panels are not intended to be attached to raw concrete,
poured concrete walls or concrete block basement walls. These are
not acceptable substrates for DumaWall panel installation. Appropri-
ate substrates would include framed walls with existing tile, drywall,
cement board, OSB, plywood, etc. DumaWall panels must be attached
to structures that comply with your local building codes and have
incorporated appropriate moisture abatement measures.
Tile dimensions: 20-7/8” x 11-3/16” x 4.2mm
1) Clean surfaces. Before starting, make sure all surfaces are clean, dry,
smooth, and free from dust, grease, wax, etc. Lightly sand any glossy surfaces
to remove sheen. Clean the back surface of the panels by wiping with a clean
cloth.
2) Dry layout. It is recommended that you perform a “dry layout” prior to
applying any adhesive. Measure walls, check for level and square. Depending
on dimensions and room construction, you may need to trim some panels
accordingly. Depending on your project, when tting for dry layout, panels
can be centered at a focal point, such as behind a sink or the center of a room.
For the purpose of the layout only, build out from both sides of the focal
point, to ensure how the tiles t into the space.
3) Skip this step unless you are
installing panels in a shower or other
water-direct environment. Installation
in environments exposed to a direct
ow of water (shower, mud room or
garage) require a 1/8-inch bead of DAP®
Kwik Seal Ultra be placed inside both
grooves on every tile (image A). Add a
bead of silicone along recently cut
edges (see instructions below) to be
placed into the corner.
Repeat this process on perpendicular
tile also facing corner (image B). The
recommended sealer: DAP® Kwik Seal
Ultra.
4) Cut DumaWall Tiles using standard
wood working tools like a table saw or
circular saw with a ne-tooth blade to
provide a clean, smooth cut (image C).
Use a 60-tooth blade or higher. To
ensure the base of the saw does not
scratch the surface of the panel, we
recommend protecting the surface
with common painter’s tape.
Alternatively, you can score one side
a few times with a utility knife and
snap the tile at the line (image D, E). This method may require sanding the
snapped edges.
BEFORE YOU BEGIN INSTALLATION
1) If you choose to nish the edges,
we recommend our trim for both
end pieces and inside corners. We
recommend using baseboard or cove
molding to nish the bottom row,
regardless of ooring material. For
both end trim pieces and corner
trims, install trim in appropriate
location prior to setting tile into trim
(image J).
If your project calls for DumaWall
panels starting at a oor, be sure the
rst row is straight and level. If you
plan to use baseboard or cove
molding at the oor/wall corner, snap
(or draw) a level line at 12 inches from
the oor. Align the tops of each panel
in the rst row to the snapped line
(image K). It is imperative that this starting row be level and straight. If you
do not intend to use baseboard or cove molding, snap or draw a level line
at 10 inches from the oor and cut the bottom of each panel as necessary
to align at the top with your level line, and to the oor.
2) To install your rst panel, begin with bottom row and work from
right to left due to the prole of interlocking tongue and grooves. Make
sure the rst panel you intend to install ts properly and is level.
You may need to place a temporary shim under each bottom tile or use
painter’s tape to hold each tile in place while the adhesive sets (image L).
INSTALLATION onto drywall, OSB, plywood
or existing tile substrates
3) Apply adhesive to the back of the
panel. The recommended adhesive is
Loctite® Power Grab Ultimate. Carefully
read and follow adhesive manufacturer’s
directions. Apply a 1/4" bead in a typical
"M" or "W" pattern, and a bead around
the tile perimeter about ½-inch in
(image M). The 10 oz. adhesive tube
covers approximately 5 wall panels.
4) Apply the panel to the substrate by
pressing it into place. Apply even
pressure with your hands across the
entire panel. If necessary use painter’s
tape, shims or pins to hold panels in
place until the adhesive sets.
5) Wipe o excess adhesive. Use water
and a cloth. Clean o any adhesive
residue that is visible while it is still wet.
Do not allow this residue to dry as it will
be dicult to clean up when dry and
could damage the nish.
6) Connect the next tile by fully
inserting the tongue into the groove
(image N).
7) Repeat until bottom row is complete.
If installing in a corner, cut o the ange
facing the corner to allow a plumb surface against the substrate. Repeat this
process on tile that abuts the previous one also facing the corner.
8) Allow the adhesive on the bottom row to set up. See adhesive manufactur-
er’s directions. The time necessary can vary from 20 minutes to several hours.
9) Determine what tile pattern you want to use before starting the second
row (image O, P). Commonly-used options are running bond (vertical joints
are staggered) and stack bond (vertical joints line up).
