Roff T21 Extrofix Ultra Tile Adhesive (Grey) for Large Format Tiles (20kg)
Roff T21 Extrofix Ultra — Tile Adhesive (Grey) for Large Format Tiles
Roff T21 Extrofix Ultra Grey is the grey counterpart of the T20 White, designed for fixing big, heavy tiles and natural stone on facades and high-traffic floors where the tile colour is dark or opaque. With the same Type 4 C2 T E S1 classification, T21 delivers maximum cementitious bond strength with S1 deformability — meaning it carries the weight of large format tiles (up to 1200×1200 mm) while flexing with building movement, thermal expansion, and structural settlement. For dark granite, slate, and opaque porcelain on exterior surfaces, T21 Grey is the top-tier choice.
Key Features
- Type 4 C2 T E S1: Maximum cementitious bond strength with high deformability
- Large Format Capable: Supports tiles up to 1200×1200 mm and heavy stone slabs
- S1 Deformability: Absorbs thermal cycling, structural movement, and dynamic loads
- Ultra-High Polymer Content: Greater polymer ratio than standard Extrofix T07
- Grey Base: Ideal for dark tiles, granite, slate, and opaque porcelain
Applications
- Large format dark tiles on building facades
- Heavy granite and slate cladding on exterior walls
- Podium decks, terrace floors, and high-traffic exterior areas
- Industrial and commercial floor tiling with large porcelain tiles
- High-rise building facade cladding (with mechanical restraints)
