GoBoard® is the new ultra-lightweight yet durable, waterproof tile backer board from Johns Manville.
ULTRA-LIGHTWEIGHT: Engineered to be dependable even though it’s much lighter weight than cement and other heavy boards, GoBoard can be installed in residential and light commercial tile applications.
EASY TO CUT, HANDLE & INSTALL: GoBoard can be quickly cut right where it’s installed with a basic utility knife without crumbling or disintegrating. And, it’s much easier to handle than cement and other heavy boards.
BUILT-IN WATERPROOFING: GoBoard saves time and money because you seal only the board joints and fastener locations for a waterproof tile assembly*.
GoBoard is available in 1/4” for floors and countertops, and 1/2” and 5/8" for walls, showers, ceilings and floors.
*Board joints and fastener locations require a waterproof sealant per GoBoard installation instructions.
Without waterproofing, water can get behind a tile installation. This applies not only to showers, but also walls, floors and countertops, as water from normal usage in a home or building can find its way onto the tile, through the installation and behind it. This can lead to mold growth and damage to the tile installation and potentially other building elements.
Some backer boards are not inherently waterproof, and a waterproof membrane is required to be installed behind (before board installation) or over (after board installation) the entire board—neither of which are necessary with GoBoard.
With GoBoard, you save time and money because you seal only the board joints and fastener locations as you install the board. Please review the GoBoard installation instructions, below, for details on how to install GoBoard for a waterproof installation.
