Sot Project
Consult your local building code and architects or
designer for specic requirements. When using
the material as sot, it is suggested that dassoXTR
Sot Shiplap planks be installed on grits or joists
with a maximum span of not more than 4’ (16”, 24”,
36”, and 48” are all acceptable). Ensure you know
which surface is the facial (the thinner surface is
the facial). Use self-tapping screws for grits and
wood screws for wooden joists. The shiplap planks
are designed to install with specic eld clip/
fastener SKU#: ASF-FC2-BK. Every end-matched
tongue and groove should be leveled with eld
clips on each side even if the join does not fall on a
grit or joist. The eld clip will ensure the ends are
ush with the row of sot planks next to the end
matched joint. Each row must be staggered so that
the joints are not aligned together on the same
position. Use D-Plug from Eisen, SKU# AGN-PSc-xxx
(x denotes unite per pack) on the starter and ending
row. Adjust the depth of countersink hole to 3/8”
(9.5mm) by shimming the setter with a washer that
is 1/8” (3.2mm) thick. Remember to shim between
the joist and the sot with 3/16” (4.5mm) shim to
keep the surface leveled. A starter clip/fastener is
also available (SKU#: ASF-SC1-BK) should you prefer
this over D-Plug. Trim could be used to cover the
perimeter of sot if it is desirable.
Deck Skirting Project
When using the material as Deck Skirting, it is
suggested that dassoXTR Shiplap planks be installed
on a framing structure with a maximum span of 2’
(16” and 24” only). Ensure you know which surface
is the facial (the thinner surface is the facial). The
shiplap planks could be nailed or screwed directly
to the framing. Use hidden or non-visible nails or
screws for best visual eect. Eisen eld clip/fastener
SKU#: ASF-FC2-BK and starter clip/fastener SKU#:
ASF-SC1-BK is recommended for the project but
the installer needs to make their own judgement
if the fastener is suitable for his project. For a
sturdy skirting surface, the joints must be laid on
joists. Use D-Plug from Eisen, SKU# AGN-PSc-xxx
(x denotes unit per pack) on the starter row and
ending row. Adjust the depth of the countersink
hole to 3/8” (9.5mm) by shimming the setter with
a washer that is 1/8” (3.2mm) thick. Planks can be
laid vertically or horizontally.
Wainscoting and Interior Wall Project
When using the material as wainscoting or interior
wall cladding, it is suggested that dassoXTR Shiplap
planks be installed as sheathing or on batten with
a maximum span of 2’ (16” and 24” only). Ensure
you know which surface is the facial (the thinner
surface is the facial). The shiplap planks are
designed to install with specic eld clip/fastener
SKU#: ASF-FC2-BK. Every end-matched tongue and
groove should be leveled with eld clips on each
side even if the join does not fall on a grit or joist.
The eld clip will ensure the ends are ush with the
row of sot planks next to the end-matched joint.
Use D-Plug from Eisen, SKU# AGN-PSc-xxx on the
starter row and ending row. Adjust the depth of
the countersink hole to 3/8” (9.5mm) by shimming
the setter with a washer that is 1/8” (3.2mm) thick.
Remember to shim above the planks with a 3/16”
(4.5mm) shim to keep the surface leveled. Planks
can be laid vertically or horizontally. When planks
are installed vertically, D-Plug has to be used on
every row along the bottom and top of each row to
secure the planks. On every interval of 18’ (3 planks'
length), the planks have to be secured directly to
the wall for additional strength.
Fastening
Set elevation lines across the wall surface to
ensure that the required level is maintained during
installation. When installing, start at the base
and move upward in complete rows. Check your
alignment and level shiplap installation of each
row. When fastening the top of the last row of your
project, the nal/top row may need to be ripped
to the proper width, pre-drilled, face screwed and
plug.
