High Performance
KC Fixit Xtreme
For larger-format tile and premium surface jobs that need a stronger bond upgrade.
Large-Format & Stone Fixing
Stone and large-format fixing systems for more critical surfaces.
Large-format and stone-look installations place a higher demand on the fixing system. Surface weight, finish value, and installation sensitivity all increase the need for stronger product selection.
KC Fixit positions Xtreme, Flex, and Superflex as stronger options for these more demanding jobs. This helps contractors and project teams choose products more confidently when the surface is heavier, denser, or more premium.
These solutions are best understood as part of a complete system: the right fixing grade, the right jointing approach, and the right surface support where needed.
