• Install 1/2"(or 5/8") GoBoard to wall studs using
GoBoard Fasteners spaced every 8"or GoBoard
Washers spaced every 12"while leaving 1/8"gaps
between subfloor and bottom edge of GoBoard and
all board joints. Fill all gaps with GoBoard Sealant
and spread excess sealant with a putty knife at least
1"from either side of joint. For the joint near subfloor,
spread sealant roughly 2"up from subfloor. For detailed
instructions, visit https://www.jm.com/content/dam/jm/
global/en/tile-backer-boards/GB-001%20GoBoard%20
Installation%20Instructions.pdf.
* Only board joints and fastener locations require a
waterproof sealant.
Make sure floor is level (floor must be level for proper
installation). Find the center of the shower pan area (or as
close to center as framing allows). Please review page 10 for
possible layouts.
Top of waste pipe MUST be at least 1 5/8"below the top of the
subfloor. For remodels, cut existing waste pipe as needed with
inside pipe cutting tool.
Using measurements from the previous step, mark the center of
the drain hole. Cut a 5"diameter hole with jig-saw, hole saw or
other means. For remodels, ensure existing drain location fits
within the layouts and dimensions outlined on page 10 and 12.
Important Information
• Make sure the waste pipe cannot be pushed
downward during GoBoard Point Drain assembly
installation. There are numerous methods to
secure the waste pipe, but the easiest method
is to place blocking underneath the drain pipe to
achieve correct distance from subfloor.

Fold corners of membrane (D) inward so that screw holes are
readily accessible. Add tape dot (J).
Remove tape dot (J) and unfold membrane (D) to view waste
pipe inside GoBoard Point Drain body. The waste pipe should be
within 1/4” or less from fins to ensure a secure and water tight
connection.
Install valve seal (G) over valve and waterproof pipe seal (H) over
shower pipe using GoBoard Sealant.
Fold front and back and then left and right of membrane (D) inward.
Install GoBoard Point Drain assembly and fasten to subfloor using
provided screws (F). Use PVC primer and solvent cement to glue

Measure the distance between the left and right walls. Ensure
there is a 1/8” gap between curb and side of walls and each
curb section if distance is greater than 48”. Cut curb section to
correct length.
Refold membrane (D) and secure corners with tape dot (J) see
steps 5 and 6) so that edge of clamping collar is exposed.
In curb location, apply two 1/4” beads of GoBoard Sealant.
Apply several 1/4” beads on curb (both sections if more than 1 curb
required) surfaces in contact with subfloor and walls. Spread excess
GoBoard Sealant onto subfloor and curb on shower side. Remove
excess sealant on bathroom side of curb.
Optional – Secure curb to subfloor with 4 1/2” screws (1 per linear
foot) to prevent accidental curb movement during remaining steps.
Apply GoBoard Sealant over lag screw locations to ensure a water-
tight installation.

After removing all wedge panels from shower pan, cut along marks
to final size. Ensure there is a 1/8” gap at clamping collar, outside
walls and between wedge panels.
Note: Use straight edge for cut (always cut to inside of mark 1/16”).
Dry fit all four wedge panels to ensure that there is a 1/8” gap
between wedge panels, clamping collar, side walls and curb.
Mix thin set mortar per manufacturers instructions and apply to
subfloor using a 3/16” V-notched trowel. Use a 1/4” x 1/4” square
notch trowel if additional height is needed or rough subfloor.
Install left and right wedge panels by pressing firmly into thin set.
Ensure that there is a 1/8” gap at clamping collar and side walls.
Note: Thicker side of wedge panels to outside of enclosure.
Using front and back panel edges, mark 45 degree angles on left
and right wedge panels.
IMPORTANT: DO NOT mark angles from corners of shower
pan area. Angles MUST be 45 degrees from center of drain

After removing tape dot and folding membrane edges up, Apply
a 1/4” bead of GoBoard Sealant on top of clamping collar near
folded membrane, fill remaining gaps between clamping collar
and wedge panels and apply another 1/4” bead of sealant
around the perimeter of the drain base approximately 1” from
clamping collar as shown.
Unfold membrane so it is lying flat over beads of GoBoard Sealant
and wedge panels. Using a putty knife, start spreading sealant
underneath membrane closest to center of drain moving out.
Continue around drain until entire membrane is adhered to
wedge panels with sealant.
Note: Use moderate pressure when smoothing and spreading
sealant under membrane. A continuous layer of sealant MUST
