GoBoard Seam Fabric

Product Long Description
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.
