GoBoard Install Guide

Introducing GoBoard
Every tiling project requires a durable, waterproof surface under
the tile, called a tile backer board.
GoBoard from Johns Manville is a new tile backer board that’s:
Ultra-lightweight: Up to 80% lighter than cement boards yet
engineered for durability
Easy to cut, handle & install: Simply attach with backer board
screws or roofing nails
Waterproof built-in: Save time and money because you only
need to seal the board edges and the fastener locations for a
waterproof tile assembly
*
*Board joints and fastener locations require a waterproof sealant per GoBoard installation instructions.
GoBoard Applications & Sizes
GoBoard is available in three thicknesses:
• ¼" for floors & countertops
• ½" for walls, showers, ceilings & floors
• ⅝" for walls, showers & ceilings
You can use GoBoard for any tiling project:

NOTE: A “fastener location” is any place where a nail or screw goes into the product
NOTE: We recommend using ¼" GoBoard for residential floors and light commercial applications
