Product Description

Roff T04 VFA White Tile Adhesive is a premium polymer-modified, low VOC tile adhesive engineered specifically for fixing ceramic, vitrified tiles, glass mosaic tiles, glass tiles of various sizes, semi-vitreous tiles, and natural stones. The white formulation is particularly suited for applications where shadow marks must be avoided on light-colored or transparent tiles.

What Makes Roff T04 VFA White Special?

White Adhesive Advantage: Unlike grey adhesives that create visible shadow marks on light-colored tiles, Roff T04 VFA White provides a clean, professional finish on glass tiles, light marble, white ceramic tiles, and light porcelain applications. This makes it the preferred choice for modern, minimalist interior designs where aesthetics matter.

Polymer-Modified Formula: The polymer modification enhances bond strength and flexibility, accommodating slight substrate movement and tile expansion during temperature changes—critical in Bangalore's climate with varying humidity levels (50-90% depending on season).

Versatile Application: Suitable for both internal floor and wall applications, Roff T04 VFA White works excellently on:

• Kitchen Backsplash: White adhesive maintains clean appearance behind transparent or light glass tiles without shadow visibility
• Bathroom Walls: Handles moisture and humidity while keeping walls looking polished with white grout and light tiles
• Living Room Feature Walls: Large transparent or light-colored tiles with premium appearance
• Marble Applications: Natural stone installations benefit from white adhesive preventing color transfer issues
• Glass Tile Installations: Transparent glass tiles show adhesive color prominently—white eliminates dark visibility

Performance in Bangalore Climate

Bangalore's humid environment, with 75-85% humidity during monsoon (June-September) and 50-65% during dry months, demands adhesives with superior water resistance. Roff T04 VFA White's polymer-modified composition ensures:

• Moisture Resistance: Maintains adhesive integrity even in high-humidity bathrooms and kitchens

Application Tips for Best Results

Surface Preparation (Critical Step):

• Remove all dust, loose mortar, paint, and algae from surface
• Make surface damp (not wet) 15 minutes before application for better adhesion
• Ensure surface is rough—smooth surfaces reduce bond; roughen if needed
• Fill gaps exceeding 10mm with cement mortar first
• Level surface using leveling guides for consistent adhesive thickness

Mixing Guidelines:

• Ratio: 1 part Roff T04 VFA White (20kg) to 5-6 litres of clean water
• Consistency: Achieve peanut butter-like texture (not too thick, not watery)
• Mix thoroughly using electric drill with paddle for 2-3 minutes
• Rest mixed adhesive 10 minutes before application (improves workability)
• Retemper only with water if mixture dries out; avoid full re-mixing
• Don't mix more than needed—use within adhesive's open time

Application Technique:

• Use 6mm x 6mm notch trowel held at 45° angle for consistent ridges
• Achieve 80-90% coverage on tile back (visible when placed)
• Press tiles firmly to eliminate air pockets and ensure full contact
• Work within open time (30-45 minutes) before surface dries
• For vertical surfaces: use thicker consistency to prevent tile slippage
• Check tile levelness every 4-5 tiles during installation

Curing Timeline (Bangalore Climate):

• Summer (March-May): 12-24 hours initial set, 24-48 hours before grouting
• Monsoon (June-September): 24-36 hours initial set, 36-48 hours before grouting (extended due to humidity)
• Water Exposure: Minimum 48-72 hours before bathroom/kitchen use
• Full Strength: 7 days for maximum durability in wet areas

Frequently Asked Questions (FAQs)

Q1: When should I use white adhesive (T04) vs grey adhesive (T03)?

A: Use Roff T04 VFA White for light-colored tiles, glass tiles, marble, and white ceramics to avoid shadow marks. Use grey (T03) for dark/medium colored tiles or when cost is primary concern. Both have identical water resistance and bonding strength—the difference is aesthetic. For premium backsplash or visible glass tile installations, white is worth the ₹87 price difference.

Q2: Is Roff T04 VFA White suitable for bathrooms in Bangalore?

A: Yes, absolutely. Bangalore bathrooms experience 80-95% humidity, especially after showers. Roff T04 VFA White's polymer-modified composition maintains adhesive integrity in high moisture. Extend drying time by 8-12 hours during monsoon season (June-September). Ensure proper ventilation to accelerate curing.

Q3: How much white adhesive do I need for my kitchen backsplash?

A: Kitchen backsplash typically covers 5-15 sq meters. With 5-6 sq meter coverage per 20kg bag, a typical 10 sqm backsplash needs 1.7-2 bags. For precise calculation: (Project area ÷ 5.5 sq meters coverage) × 20kg per bag. Add 10% extra for waste. Example: 10 sq meters ÷ 5.5 = 1.82 bags, round up to 2 bags (40kg total).

Q4: Can I use T04 White on large format tiles (600mm+)?

A: Roff T04 VFA White works for standard size tiles up to 300-400mm. For large format tiles (600mm+), Roff recommends Roff T20 Extrofix Ultra which offers superior bond strength, extended open time (2 hours), and flexibility needed for large tiles. Large tiles' weight demands T20's premium performance.

Q5: How long before I can grout after applying Roff T04 VFA White?

A: Minimum 24 hours in summer (March-May), 36 hours in monsoon (June-September). In Bangalore's humid climate, extending to 48 hours is safer, especially in monsoon. Touch-test: adhesive should not dent with thumb pressure. Never grout until adhesive fully sets.

Q6: What's the shelf life of Roff T04 VFA White powder?

A: Unopened bags: 12 months in cool, dry storage. Opened bags: use within 2-3 weeks if stored in sealed bags. Bangalore's high humidity can cause powder to absorb moisture, affecting mixing quality. Store in well-ventilated, moisture-controlled area. Never store in bathrooms or damp areas.

Q7: Is Roff T04 VFA White better than MYK Laticrete for white tile applications?

A: Both are quality products. Roff T04 VFA White is locally established with proven Bangalore performance and 24-hour HomeRun delivery. Choice depends on availability and preference. For light-colored tiles specifically, white formulation ensures no shadow marks regardless of brand.

Q8: Can I mix Roff T04 VFA White with other adhesives?

A: No. Never mix different adhesive brands or types. Each formula has unique polymer composition and curing properties. Mixing can compromise bond strength and durability. If you need to switch adhesives mid-project, allow first adhesive to fully cure (48 hours), then prepare surface before applying new adhesive.

Q9: Does Roff T04 VFA White contain harmful chemicals or VOCs?

A: Roff T04 VFA White is low VOC (volatile organic compounds) formulated, making it safer for indoor bathroom and kitchen applications. It's free from heavy metals and contains no asbestos. Suitable for residential and commercial applications. Ensure proper ventilation during mixing and application as good practice.

Q10: What's the cost-benefit of Roff T04 VFA White at ₹672 vs T03 VFA Grey at ₹585?

A: The ₹87 per bag premium for white adhesive is worth it for visible installations (kitchen backsplash, bathroom walls with light tiles, glass tile features). For non-visible areas or dark tiles, grey is sufficient. For a 20-bag project, the premium is ₹1,740 total—minimal cost for professional appearance on premium tile investments.
