Tiles And Stone Adhesives
Polymer-modified cement-based formulas for interior and exterior ceramic, vitrified tiles, granite, Italian marble, and large formats.
Engineering Overview
Gaucera engineered tile adhesives are advanced polymer-modified cementitious thin-set mortars formulated according to IS 15477:2019 and EN 12004 standards. Engineered with superior grab, zero vertical slip, and extended open time, Gaucera adhesives deliver permanent bonding for ceramic, porcelain, vitrified tiles, natural stones, Italian marble, granite, and jumbo-format slabs across demanding interior and exterior floor and wall applications.
Key Performance Highlights
- IS 15477:2019 Certified (Type 1, Type 2, Type 3, Type 4) & European Standards EN 12004 (C1T to C2FT S2)
- Zero Vertical Slip: Superior mechanical grab eliminates sagging on vertical wall installations
- Extended Open Time (>30 min): Permits comfortable alignment and large surface spreading without skinning
- High Shear & Tensile Adhesion (up to 3.25 N/mm²): Withstands structural movement, vibration, and thermal shocks
- Gel & Fibre Reinforcement Technology (World - 1): Microfibres absorb shear stress in facade and heavy-traffic environments
- Deformability Class S1 & S2: Exceptional flexibility for large-format slabs up to 120x240cm and tile-on-tile renovation

Step-by-Step Installation Process
1. Surface Preparation
Ensure substrate is clean, sound, dry, flat (within 6mm per 3m), and free from dirt, oil, grease, curing compounds, and loose particles. Allow new concrete to cure for at least 28 days.
2. Mixing
Mix 20 kg adhesive with 4.5 to 5.5 litres of clean potable water using a slow-speed mechanical stirrer (approx. 400 RPM) for 3-5 minutes until a smooth, lump-free paste is formed. Allow 5 minutes slake time, then remix briefly before application.
3. Application
Apply adhesive to the substrate using the flat side of a notched trowel to create a contact layer, then comb with the notched side at a 45° angle. Use 6x6mm trowel for small tiles, 10x10mm or 12x12mm for large formats. For slabs >60x60cm, back-butter the tile with a 1-2mm layer.
4. Placement & Fixing
Press the tiles firmly into wet adhesive with a twisting motion to ensure >90% coverage for interiors and 100% for exteriors/heavy traffic. Tap lightly with a rubber mallet. Tile adjustment time is 20-25 minutes.
5. Grouting & Curing
Leave joints clear for grouting. Allow 24 hours before grouting with Gaucera Smart Epoxy Grout or Smart Grout. Protect installation from water and traffic for 48 to 72 hours.
Critical Installation Instructions & Standards
Mandatory site protocols for substrate preparation, mechanical fixing, expansion joints, and curing.
• Primer Application: Use a suitable back tile primer or equivalent product to improve adhesion.
• Mechanical Fixation: For tile installations higher than 10 feet (indoors or outdoors), use mechanical fasteners to ensure overall stability and safety.
• Substrate Preparation: All surface areas must be plumb and true within 6 mm per 10 ft (3 m). Allow concrete slabs to damp cure for at least 28 days.
• Expansion Joints: Provide expansion joints every 3 to 4 metres and seal with appropriate flexible sealant; never cover expansion joints with thin-set adhesive or tile.
• Curing Protocol: Allow the surface to settle for 48 to 72 hours depending on climatic conditions.
