GoBoard® Seam Fabric is a lightweight, point bonded non-woven that is specifically designed to enhance the performance of all GoBoard products. When used with GoBoard Tile Backer Board and GoBoard Wedge, installers can expect increased tensile strength at the joints and in the change of planes. Get to tile faster using GoBoard Seam fabric due to superior adhesion between GoBoard Pro Sealant and thin-set mortars. And best of all, there’s no need to wait for the sealant to skin over.

  • Alkali resistant
  • Improved shear bond strength (30%+)
  • Increased Joint strength (50%+)
  • Shortens the time to tile

GoBoard Washers can be used in all GoBoard tile backer board applications for maximum holding strength. Take advantage of increased allowable spacing when used in combination with GoBoard Fasteners, or fortify your installation for heavier or larger format tile.

GoBoard® Washers are hardened steel washers that provide maximum holding strength when fastening tile backer board to stud framing. Each washer has tabs for pre-positioning prior to driving the fasteners. These reverse tabs also prevent the washers from stacking while packaged – making them easy to separate. When using GoBoard Washers in your installation, the fastener spacing increases to 12 inches.

  • Wood and metal studs
  • 12-inch spacing
  • Corrosion-resistant
  • East installation

GoBoard Fastener/Washer combo packs come with 100 pieces each and are for use on:

  • 1/4″ for floors and countertops
  • 1/2″ and 5/8″ for walls, showers, ceilings, and floors

GoBoard Fasteners are the preferred fastening mechanism for any GoBoard tile backer board application for both wood and metal stud framing.

GoBoard® Fasteners are tile backer board fasteners designed for securing GoBoard to wood or metal studs, as well as subfloors. These corrosion-resistant fasteners have larger diameter heads for more holding power and the smooth underside of the head helps mitigate over-driving the screw. GoBoard Fasteners are available in contractor packs of 700 pieces and come with the required T-25 Torx head bit. Using GoBoard Washers is optional with these tile backer board fasteners, depending on your application.

  • Wood and metals studs
  • Corrosion-resistant
  • T-25 Torx bit included
  • Easy installation
     

GoBoard tile backer board fasteners are for use on:

  • 1/4″ GoBoard for floors and countertops
  • 1/2″ and 5/8″ GoBoard for walls, showers, ceilings, and floors
