KERDI-FIX is Schluter's own bonding and sealing compound — it's what you use to attach KERDI components to each other and to the substrate when mechanical fastening alone isn't enough. It's also the right product for sealing around pipe penetrations and fixtures in KERDI shower systems.

• Dual function: Adhesive AND waterproof sealant in one — bonds KERDI-BOARD panels, seals pipe penetrations, and bridges small gaps
• Compatibility: Designed specifically for Schluter KERDI system components — known to play nice with the fleece backing and sealing geometry
• 290ml cartridge: Standard caulk gun size — enough to seal a full shower pan perimeter and pipe penetrations on most standard shower builds

Pro Tip: KERDI-FIX is not a structural adhesive — it's designed to supplement mechanical fastening and create watertight seals at joints and penetrations. Don't use it to substitute for proper thinset bed under the membrane. Use it where water needs to stop. Ships from Canadian warehouses. Earn 3% back with YourFloors rewards.
