6 Tubes ShowerSeal® Polyurethane Sealant, and 2lb. of Screws

+ Description

GoBoard® is up to 80% lighter than cement backer boards, yet engineered and rigorously tested for strength and durability. This tile backer board has waterproofing built-in, and can be easily cut in the field with a basic utility knife without crumbling or disintegrating. This ultra-lightweight material is not only durable, but serves as the ideal alternative to cement and other heavy tile backer boards. GoBoard® helps you to complete the job faster and more cost effectively, with no strain on your back.

Complete shower tile projects in half the time or less. Install GoBoard with Sealant, take a break and tile the same day. Grout the next day and the project is done*.

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.

GoBoard can be quickly cut right where it’s installed with a basic utility knife without crumbling or disintegrating. It’s also much easier to handle than cement and other heavy boards.

GoBoard saves time and money because you seal only the board joints and fastener locations for a waterproof tile assembly**.

  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 backer board 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).
