Kerabond T — White Premium Cement-Based Tile Adhesive

Kerabond T is a cement-based adhesive designed for fixing all types of ceramic tiles and mosaics to internal and external walls and floors. When mixed with ISOLASTIC, it offers improved performance and increased flexibility. Coverage: approx. 2–5 kg/m² depending on tile size and trowel used.

Where to Use

• Fixing ceramic tiles and mosaics on walls and floors (internal & external).
• Spot-bonding insulating materials such as polystyrene, polyurethane, rock wool, glass wool, wood-cement and sound-deadening panels.
• On conventional renders, cement mortar walls, concrete slabs, reinforced floating slabs and primed gypsum or anhydrite screeds.

Recommended with ISOLASTIC

Mix Kerabond T with ISOLASTIC in the following cases:

• Insulated concrete walls or precast structures
• Underfloor heating installations
• Large-format tiles and glass mosaics
• Stone materials (if not moisture-sensitive)

Not Suitable For

• Wooden substrates or gypsum board walls without primer
• Metal, rubber, PVC, or linoleum surfaces
• Adhesive layers over 5 mm thick
• Areas requiring rapid setting for light foot traffic

Preparation

Substrates must be cured, dry, sound, and free from dust, grease, oils, paint or wax. Cement screeds must be cured for at least 28 days, concrete for 6 weeks, and renders for 1 week per cm thickness. Gypsum/anhydrite screeds must be primed with Primer G or Eco Prim T Plus.

Mixing

Mix 20 kg of Kerabond T with 4.8–5.2 L of clean water using a slow-speed mixer until lump-free. Leave for 5–10 minutes, remix, then apply. Pot life: approx. 8 hours.

Application

• Apply with a notched trowel ensuring 65–70% coverage for walls and 100% for floors and external use.
• Mosaics (≤5x5 cm): MAPEI No.4 trowel.
• Ceramic wall tiles: MAPEI No.5 V-notched trowel (~2.5–3 kg/m²).
• Floors/irregular backs: MAPEI No.6 V-notched trowel (~4–5 kg/m²).
• Large/external tiles: back-buttering recommended.

Grouting & Sealing

• Wall joints: grout after 4–8 hours
• Floor joints: grout after 24 hours
• Expansion joints: seal with MAPEI sealants

Technical Data

• Coverage: 2–5 kg/m² (depending on tile size/trowel)
• Open time: 20–30 minutes
