Roff T20 Extrofix Ultra Tile Adhesive, White, 20 Kg Bag

Roff T20 Extrofix Ultra Tile Adhesive is a premium highly polymer-modified white adhesive specially engineered for the installation of large format tiles measuring 60 cm and above. Designed for demanding residential and commercial applications, the advanced formulation delivers exceptional bonding strength, enhanced flexibility, and superior support for heavy and oversized tiles. Its white adhesive base prevents shadow marks and color bleed-through behind light-coloured, translucent, transparent, and glass tiles, ensuring a flawless aesthetic finish for premium tile installations.

The adhesive is particularly suitable for luxury homes, commercial spaces, hotels, offices, retail environments, and feature wall installations where large format tiles require precise alignment and long-lasting structural performance. The advanced polymer modification provides strong adhesion and improved handling characteristics for large and heavy tiles while minimizing installation challenges commonly associated with oversized tile formats. Its white formulation preserves the true appearance of light-coloured and transparent tiles by eliminating dark background shading that may occur with standard grey adhesives.

One of the key advantages of Roff T20 Extrofix Ultra is its extended open time of approximately 30–40 minutes, which gives installers additional working time for accurate placement, alignment, and adjustment of large format tiles. This extended working window is especially valuable for feature walls, large floor layouts, and premium projects where precision and finish quality are critical.

For optimal installation results, the substrate should be perfectly level, clean, dry, and free from dust, grease, oil, or loose particles before application. The adhesive should be mixed thoroughly with clean water until a smooth, lump-free white consistency is achieved. Apply the adhesive evenly using a large notched trowel suitable for the tile dimensions to ensure proper adhesive coverage and support beneath the tile surface. Large tiles should be pressed firmly into the adhesive bed and adjusted within the 30–40 minute open time to achieve perfect alignment and full contact. Due to the size and weight of large format tiles, proper coverage and leveling are essential for long-term performance. After installation, allow a curing period of approximately 48–72 hours before grouting or exposing the tiled surface to traffic to ensure maximum bonding strength and durability.
