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.

Secure curb to subfloor with 4 1/2” screws (1 per linear
foot) to prevent accidental curb movement during remaining steps.

tight installation.
