PU Flexible Tile Adhesive Wholesalers In Lucknow

PU Flexible Tile Adhesive refers to a polyurethane-based adhesive designed for fixing tiles, particularly where flexibility and strong bonding are essential. It is often used in areas subject to vibration, thermal movement, or where traditional cement-based adhesives may fail.

🔧 Key Features of PU Flexible Tile Adhesive

High Flexibility

Absorbs vibrations and movements in substrates (ideal for wood, metal, gypsum boards, etc.).

Prevents cracking and debonding in tiles due to thermal expansion or structural movement.

Strong Bond Strength

Excellent adhesion to various substrates (concrete, metal, wood, plastic, ceramics).

Supports heavy tiles and stones on both vertical and horizontal surfaces.

Water and Chemical Resistance

Suitable for wet areas like bathrooms, kitchens, pools.

Resistant to cleaning chemicals and moisture ingress.

Fast Curing

Reduced downtime; suitable for commercial applications where speed matters.

Temperature Resistance

Works well in extreme temperatures (both hot and cold environments).

🧱 Applications

Interior and exterior tiling

Fixing tiles on flexible or non-rigid surfaces (e.g., plywood, fiber cement boards)

Bathrooms, kitchens, swimming pools

Renovations over existing tiles

Balconies and terraces

Industrial areas with heavy traffic or machinery

✅ Advantages over Cement-Based Adhesives

Greater flexibility and elasticity

Superior bonding on non-porous surfaces

Better performance in harsh environmental conditions

⚠️ Precautions

Use in well-ventilated areas (may emit mild odors during curing)

Gloves and eye protection recommended during application
