  1. Measure GoBoard®, then score with a utility knife and snap to desired size - Fast & Easy
  2. Liberally apply a continuous bead of KBRS ShowerSeal® Polyurethane Sealant to the bottom edge floor or ShowerSlope™, so that when butted the sealant squeezes out. Ensure a tight seal at all joints and seams.
  3. Fasten the GoBoard® to the studs, using backerboard screws (provided in kits), flush to the surface of the board at a maximum spacing of 8" and within 1/2" - 1" of the perimeter edges.
  4. After fastening, spread the excess sealant with a putty knife to at least 1" beyond either side of the joint to ensure a tight seal. Liberally apply a continuous bead of KBRS ShowerSeal® Polyurethane Sealant (provided in kits) to the top of the walls before tightly butting the next board.
  5. Repeat the above two steps as necessary to completion.
  6. To ensure a waterproof installation, all screw fastened locations and and joints (between boards, at corners and for other changes of plane) must be sealed with KBRS ShowerSeal® Polyurethane Sealant (provided in kits).

GoBoard® by Johns Manville is an ultra-lightweight, waterproof and durable tile backer board that is easy to cut and install. GoBoard® is engineered and tested for strength and durability, yet can be cut right where it’s installed using a utility knife. Plus, it's up to 80% lighter than traditional boards. Installation time is reduced because waterproofing is built-in, eliminating extra steps since only board joints and fastener locations need to be sealed.
