Mapei Highly Deformable PU Tile Adhesive, 10Kg, Suitable for Heavy-Duty Tiling on Facades, Balconies and Metal Surfaces - Grigio

Mapei Keralastic T Grigio 10Kg is a polymer-modified, cementitious levelling mortar designed for installing ceramic tiles and natural stones on floors and walls. It is semi-fluid and self-levelling, providing excellent adhesion, abrasion and water resistance, enabling fast and economical installations.

Key benefits include strong adhesion to both old and new cementitious substrates, high deformability to accommodate substrate movement, low shrinkage to reduce finishing work, good abrasion and water resistance, and a fast installation with minimal finishing time.

Ideal for ceramic tiles and natural stones on floors and walls, including old cementitious substrates, concrete, and prepared substrates in both interior and damp areas.

Mix with clean water following the product guidelines to obtain a semi-fluid, levelled consistency that allows easy troweling and self-levelling. Use a suitable whisk or mixer until a smooth, lump-free paste forms, then apply within the pot life indicated in the product datasheet.

Suitable for ceramic tiles, porcelain, and natural stones of various sizes and thicknesses. Its high deformability makes it compatible with larger-format tiles and uneven substrates.

If you’re considering alternatives on Fepy, you might also look at Mapéi Ultralite S1 (lighter, easy to handle), Mapéi Keraflex Maxi S1 (high flexibility for larger tiles), and Mapei Keralastic T 20kg (same family in a larger bag). Compare features like adhesion, open time, pot life, and suitability for damp areas.

1) Prepare the substrate and ensure it's clean, dry and sound. 2) Mix to a smooth, levelled consistency. 3) Apply with an appropriate trowel, place and align tiles or stones, and adjust as needed. 4) Allow curing according to the product datasheet and environmental conditions. Avoid heavy traffic and ensure proper ventilation during cure.

Yes. It is cement-based with polymer modifiers, so wear PPE (gloves, eye protection, and respiratory protection in dusty environments). Use in well-ventilated areas. The formulation is designed to be environment-friendly, but always follow SDS and local regulations.

Mapei Keralastic T Grigio 10Kg offers strong adhesion, fast installation and durability, delivering good value for tiling projects. If you’re buying from Fepy, review their return policy for returns or exchanges if the product doesn’t meet your project requirements.
