Product Description

What Makes T20 Extrofix Ultra Special

Roff T20 Extrofix Ultra Adhesive is a high polymer-modified, highly flexible tile adhesive engineered specifically for premium applications involving large format tiles, natural stones, and decorative elements. Unlike standard adhesives, T20 combines superior slip resistance with extended open time and excellent bond strength—making it the professional choice for demanding installations.

Ideal Applications for Large Format Installations

1. Marble & Natural Stone Cladding: T20 is specifically formulated for marble slabs, limestone, granite, and travertine where flexibility and bond strength are critical. The white color prevents visibility of the adhesive through semi-translucent stones.

2. Glass Tile & Mosaic Applications: Perfect for decorative glass tiles, glass mosaic, and glass block installations where the white adhesive ensures a clean, professional appearance without color bleeding through.

3. Large Format Ceramic & Vitrified Tiles: Ideal for 60cm×60cm tiles, 80cm×80cm slabs, and larger ceramic or porcelain tiles on both walls and floors. The extended open time accommodates larger surface areas without adhesive skinning over.

Bangalore Climate Performance

In Bangalore's warm, humid climate, T20 performs exceptionally well:

• Monsoon Season (June-September): Higher humidity (70-90%) requires 24-36 hours full curing time. Allow extended drying between grouting and water exposure.
• Summer Performance: Fast surface drying in heat (March-May) makes T20 ideal, but ensure substrate is not overly porous to prevent moisture loss. Water the substrate lightly before application.

Technical Specifications

Tile & Material Compatibility

• Ceramics: All ceramic tile types (glazed, unglazed, semi-vitrified)
• Vitrified Tiles: Fully vitrified, porcelain, and high-strength tiles (low porosity)
• Natural Stones: Marble, limestone, granite, travertine, slate, sandstone
• Glass Tiles & Mosaics: Decorative glass, glass block, frosted glass (white adhesive prevents discoloration)
• Large Slabs: Thin stone veneers, thin porcelain slabs, and ultra-large format tiles
• Specialty Materials: Terracotta, quarry tiles, pavers, precast terrazzo

Mixing:

• Mix 1 kg adhesive with 250-300 ml water using a drill mixer for 2-3 minutes
• Allow 5 minutes slaking time, then remix briefly before application
• Achieve a thick, creamy consistency that spreads without sagging on vertical surfaces
• Prepare only the amount you can use within 30-40 minutes (open time)
