Mapei Kerabond T C1T Tile Adhesive

Product Overview

Developed by Mapei in Italy, Kerabond T is a cementitious tile adhesive that is simply mixed with water before use. The product features excellent non-slip properties — tiles will not slide on vertical surfaces, allowing top-to-bottom installation without spacer pegs, making it ideal for all types of wall tiling work. After curing, shrinkage is minimal, providing stable bonding to common construction substrates.

When mixed with Mapei Isolastic latex (replacing water), performance is upgraded to C2ES2 class (per manufacturer data) — a highly deformable improved cementitious adhesive with extended open time, suitable for more demanding applications.

Key Features

• Non-slip — tiles stay in place on vertical and ceiling surfaces; top-to-bottom installation possible
• Strong bonding — excellent adhesion to rendered surfaces, concrete, cement mortar and other common substrates
• Extended working time — long pot life after mixing, convenient for large-area applications
• Low shrinkage — minimal shrinkage after curing, reducing risk of debonding
• Low emissions — EMICODE EC1 R Plus certified (per manufacturer data), very low VOC emissions
• Versatile — can be combined with Isolastic to upgrade performance class for demanding conditions

Applications

• Indoor and outdoor floor and wall installation of all types of ceramic tiles (glazed, full-body, quarry tiles, paper-faced and mesh-backed mosaics, etc.)
• Tiling on rendered and cement mortar surfaces
• Tiling on concrete slabs and reinforced concrete floating slabs
• Gypsum substrates and anhydrite screeds (primer required)
• Spot-bonding insulating panels (EPS, polyurethane, rock wool, etc.)

Recommended to Use with Isolastic

Important Notes

• Substrate must be sound, clean, and free from grease, dust and loose material before application
• Cement substrates must be fully cured; do not tile on substrates still subject to shrinkage
• Gypsum and anhydrite substrates must be abraded and primed before tiling
• Protect from rain and direct sunlight after application; curing time depends on weather and humidity conditions
• Product contains cement — wear protective gloves and goggles during application
• For professional use only
