Installation Guide

WALLS
Framing Requirements:
• All framing should comply with local building
code requirements.
• Framing members shall be spaced a maximum of
16" o.c. and shall be a minimum of 2"x 4" nominal
(wood) or No. 20 gauge (metal).
• Studs shall be furred out flush with receptors and
GoBoard
™
edges should be continuously supported.
Installation:
• Measure the first GoBoard
™
to fit at the bottom of the
wall and then lightly score one side with a utility knife and
quickly snap to desired size. Pre-marking the stud positions
on GoBoard
™
will aid in fastening.
• Liberally apply a bead of sealant, as specified in the
Approved Materials section, to the bottom edge of
GoBoard
™
so that when it is butted at the base the sealant
squeezes out. Fasten GoBoard
™
to the studs with backer
board screws or roofing nails, as specified in the Approved
Materials section, flush with the surface of the board with
a maximum spacing of 6" and within 1/2"– 1" of the edge.
Thinly spread excess sealant to ensure a tight seal at
the base joint.
• Again, liberally apply a bead of sealant, as specified in the
Approved Materials section, to the top edge, so that when
it is butted the sealant squeezes out and then tightly butt
the next GoBoard,
™
ensuring a tight seal at the joint. Fasten
GoBoard
™
to the studs, as above, and thinly spread the
excess sealant with a putty knife or other flat surface.
• Once all boards have been installed in this manner, seal
all fastener locations and joints (between boards and at
all corners and other changes of plane) with sealant, as
specified in the Approved Materials section.
• Joint Sealing Alternative: Leave a maximum 1/8" gap
between boards and fill the joint gaps with mortar, as
specified in Approved Materials section. Place 2" alkali
resistant fiber glass mesh tape on the joint and embed
with mortar, ensuring it is fully covered. Then, if a
waterproof installation is required, seal all joints and
fastener locations with two coats of liquid waterproofing
membrane, as specified in the Approved Materials section.
STEAM SHOWERS
• Follow GoBoard
™
wall and ceiling installation instructions.
However, either first install a manufacturer approved
vapor barrier directly to the wall studs and ceiling framing
behind GoBoard
™
per the manufacturer’s instructions or
install a manufacturer approved vapor barrier or waterproof
membrane over the external surface of GoBoard
™
per the
manufacturer’s instructions.
CEILINGS
Framing Requirements:
• All framing should comply with local building code
requirements and must be capable of supporting total
system dead load with deflection not to exceed L/360
of the span.
• Framing members shall be spaced a maximum of 16" o.c.
and GoBoard
™
edges should be continuously supported.
Installation:
• Starting on one edge of the ceiling, measure the first
GoBoard
™
to orient in the same length-wise direction as
the wall installation and then lightly score one side with a
utility knife and quickly snap to desired size.
• Utilizing either joint sealing method in the wall installation
instructions, fasten GoBoard
™
to the ceiling studs with
backer board screws or roofing nails, as specified in the
Approved Materials section, flush with the surface of the
board with a maximum spacing of 6" and within 1/2"– 1" of
the edge around the perimeter.
• Working across the remainder of the ceiling, ensure that
all GoBoard
™
joints, change of plane joints and fastener
locations are sealed.
FLOORS
• Follow GoBoard
™
1/4" wood floor or concrete floor
installation instructions.

WOOD FLOORS
Framing, Control Joints and Subfloor Requirements:
Framing:
• All framing should comply with local building
code requirements.
• Support framing must be designed for a maximum
allowable assembly deflection of L/360 (L/720 for stone)
under all intended live loads.
Control Joints:
• Consult TCNA Handbook installation Method EJ171.
• Location, width and details of control joints should follow
sound architectural practices.
• Architect, builder or design professional must specify
location of all control joints.
Subfloor:
• Joist spacing should not exceed 24" o.c.
• Exterior grade 5/8" plywood or 3/4" OSB should be
securely glued and fastened to joists.
Installation:
• Measure GoBoard,
™
then lightly score one side with a
utility knife and quickly snap to desired size. Repeat for
other required boards.
• Stagger all board joints, ensuring that they do not line up
with subfloor joints, and leave a 1/8" space between all
corners and edges.
• Apply mortar, as specified in the Approved Materials
section, to the subfloor, combing it into a ribbed setting
bed with a 1/4" square notched trowel.
• Laminate pre-cut GoBoard
™
to subfloor by firmly pressing
it into the mortar, ensuring that it is fully embedded.
• Fasten GoBoard
™
to the subfloor with backer board
screws or roofing nails, as specified in the Approved
Materials section, flush with the surface of the board with
a maximum spacing of 6" and within 1/2"– 1" of the edge
around the perimeter.
• Fill all joint gaps with mortar, as specified in the
Approved Materials section. Place 2" alkali resistant
fiber glass mesh tape on the joint and embed with mortar,
ensuring it is fully covered.
• If a waterproof installation is required, seal all joints and
fastener locations with two coats of liquid waterproofing
membrane, as specified in the Approved Materials section.
CONCRETE FLOORS
Installation:
• Ensure that concrete floor is clean and fully cured and
pre-fill surface imperfections with mortar, as specified in
the Approved Materials section.
• Follow wood floor installation instructions. However,
skip the fastening step and ensure that GoBoard
™
is
fully embedded in the mortar.
COUNTERTOPS
Installation:
• Securely fasten 3/4" exterior grade plywood to the cabinet,
ensuring that maximum surface variation is no more than
1/8" in 10' from the required plane.
• Measure GoBoard,
™
then lightly score one side with a utility
knife and quickly snap to desired size. Repeat for other
required boards.
• Apply mortar, as specified in the Approved Materials
section, to the plywood base, combing it into a ribbed
setting bed with a 1/4" square notched trowel. Fully embed
GoBoard
™
by firmly pressing it into the mortar.
• Fasten GoBoard
™
with backer board screws or roofing
nails, as specified in the Approved Materials section, flush
with the surface of the board with a maximum spacing of
6" and within 1/2"– 1" of the edge around the perimeter.
• Fill all joint gaps with mortar, as specified in the
Approved Materials section. Place 2" alkali resistant
fiber glass mesh tape on the joint and embed with mortar,
ensuring it is fully covered.
• Seal all joints and fastener locations with two coats
of liquid waterproofing membrane, as specified in the
Approved Materials section.
