Roff Vitrofix Ultra Adhesive T05 & T06

Roff Vitrofix Ultra Adhesive is a high-performance, heavily polymer-modified, cement-based thin-set adhesive designed by Pidilite Industries. Specifically engineered to step up where standard adhesives face structural limits, it is the professional choice for installing large-format tiles, heavy slabs, and low-porosity materials on both vertical and horizontal surfaces.

Modern architecture demands jumbo vitrified tiles and heavy natural stones that exert massive dead weight on walls and floors. Roff Vitrofix Ultra solves this challenge by blending immense mechanical grip with chemical flexibility, successfully absorbing substrate deformations and high thermal stress without debonding. It complies fully with the rigorous performance standards of IS 15477:2019 Type 3 'T' and global ISO 13007 C2TE classifications.

Key Features & Benefits

• High Structural Adhesion: Formulated with advanced, premium polymers that deliver exceptional tensile and shear bond strengths, ensuring heavy slabs remain locked to the structure permanently.
• Advanced Non-Slip Vertical Grip ('T'): Engineered with an exceptional sag-resistant formula that instantly grabs and anchors large wall tiles, eliminating sliding or shifting during vertical installation.
• Extended Open & Adjustability Window ('E'): Provides an open working time of minimum 30 minutes, giving tile laying crews plenty of time to precisely slide, align, and level large format panels before the initial set.
• Thermal & Heat Ageing Stability: Highly stable under temperature fluctuations, making it ideal for high-temperature zones like saunas, jacuzzis, and steam rooms.
• Waterproof Matrix: Performs efficiently in both continuous wet and dry environments, acting as a low-permeability shield against moisture ingress.
• Eco-Safe Low VOC Formula: Certified with exceptionally low Volatile Organic Compounds (VOC), protecting indoor air quality for healthy residential and commercial spaces.

Primary Applications

• Premium Materials: Perfect for large-format vitrified tiles, porcelain slabs, slim tiles, glass mosaics, marble, granite, and select natural stone installations.
• Compatible Substrates: Seamlessly bonds over concrete beds, sand-cement plasters/renders, cementitious screeds, and smooth building surfaces.
• Areas of Use: Highly recommended for interior floors and walls across luxury homes, high-traffic commercial hubs, hotels, and balconies. It is also fully suitable for exterior floor applications.

The Variants of Roff Vitrofix Ultra Adhesive

To seamlessly accommodate varying tile background tones and prevent aesthetic staining on luxury materials, the Vitrofix Ultra series is divided into two distinct models based on its cement powder base:

1. Roff T05 Vitrofix Ultra Grey

• The High-Strength Core Standard: Formulated with a premium grey cement base.
• Best Used For: Standard large-format vitrified flooring, dark-toned porcelain tiles, heavy granite panels, and darker natural stones where an underlying dark adhesive background won't affect the stone's surface color.
• Packaging Size: Available in heavy-duty 20 Kg bags.

2. Roff T06 Vitrofix Ultra White

• The Translucent & Marble Specialist: Formulated with high-grade, high-purity white cement.
• Best Used For: Specifically required for glass mosaic tile layouts, light-colored imported marbles (like Satuario or Carrara), quartzite, and translucent stones. Using a regular grey adhesive under these materials can create ugly gray shadows or bleed color through the tile; T06 White ensures the true design and color remain flawless.
• Packaging Size: Available in heavy-duty 20 Kg bags.

Application Guidelines

1. Surface Prep: Ensure the underlying substrate is structurally rigid, level, clean, and dry. If the surface is dusty or highly absorbent, lightly dampen it with water shortly before applying the adhesive.
2. Mixing: Always add the powder to measured clean water. Use a slow-speed mechanical stirrer to blend thoroughly for 3 to 5 minutes until a uniform, lump-free paste forms. Let the paste rest (slake) for 2–3 minutes, then remix briefly before starting application.
3. Combing: Apply the mixed paste to the substrate using an appropriately sized notched trowel. Only spread an area that can be completely tiled within 15 minutes to prevent premature surface skinning.
4. Fixing & Curing: Press the tile or heavy stone firmly into the combed adhesive ridges with a subtle twisting movement. Tap gently with a rubber mallet to level the tiles and achieve 100% full-bed coverage, eliminating hollow air pockets. Maintain uniform spacing using tile spacers. Allow the layout to cure for 24 hours before initiating joint grouting or permitting foot traffic.
