Getting Started: Products
Step-by-step instructions are on the following pages, but first, here’s everything
you’ll need to complete your project, in addition to GoBoard, by application type:
1/4" GOBOARD TO INSTALL ON WOOD FLOORS, CONCRETE FLOORS & COUNTERTOPS:
1
Dry set mortar or polymer modified thinset mortar to bond GoBoard
2
Galvanized roofing nails (1½" long) or backer board screws (1¼" long) to fasten GoBoard
(skip if fastening to concrete floors)
3
Fiber glass mesh tape embedded in mortar to seal all joints and fastener locations
4
Two coats of liquid waterproofing membrane to seal all joints and fastener locations*
1/2" GOBOARD TO INSTALL ON WALLS, STEAM SHOWERS, CEILINGS & FLOORS:
1
To seal all joints and fastener locations:
a. Polyurethane sealant/caulk
b. Fiber glass mesh tape embedded in dry set mortar or polymer modified thinset mortar**
2
Galvanized roofing nails (1½" long) or backer board screws (1¼" long) to fasten GoBoard

• Utility knife
• Pencil or pen for marking
• Straight edge (like a ruler or t-square)
• Measuring tape
• Putty knife
• ¼" square notched trowel
• Caulk gun
• 1"–3" paint brush (for liquid sealant)
• Appropriate roofing nail or backer board
screw fastening device (nail gun on a lower
pressure setting or drill)
Make sure you have all the right tools (pictured to the right):
NOTE: Use backer board screws if fastening GoBoard to steel
NOTE: Shorter screws can be used if fastening GoBoard to thinner countertops
Getting Started: Prep Steps
Prior to installation, make sure your space is fully prepped:
• Remove fixtures in bathroom and shower like faucets and towel racks
• Remove any nearby electrical outlets, trim, old tile and setting materials
down to wall studs and subfloor
• Address signs of mold on the studs and subfloor and make repairs as needed
• Ensure subfloor is in good condition with no squeaks or loose boards
• Replace any subfloor sections and install additional fasteners as needed
• Shim or replace any bowed studs to make sure you have a flat wall
• Add additional studs if they are spaced more than 16” on center
• Follow shower pan instructions for drain location and wall preparation for shower pan
• Reroute plumbing and electrical if you’re changing the layout of the bathroom
• Mask doorway and studs
• Turn off the power to the room being tiled
NOTE: Please ask a professional if you have any questions about how to safely prep your space!
*You must waterproof steam shower applications with two coats of liquid waterproofing membrane, or use
a separate vapor barrier. It is optional, but recommended, to add waterproofing membrane to all additional
installations for a full waterproof installation. If you use polyurethane sealant/caulk, that is already
considered a waterproof seal, and you don’t have to add the additional waterproofing membrane.
**If you use mesh tape and mortar, you don’t have to also use polyurethane sealant except between
GoBoard and your shower pan or bathtub, if applicable for your installation.
