Why Choose
SF 735?

✓
Multipurpose Use — A single adhesive solution for floor and wall tiles, porcelain slabs, granite, marble, and natural stones — indoors and outdoors.
✓
Semi-Flexible S1 Class — Transverse deformation meets S1 class requirements, allowing the bond to accommodate minor substrate movement and thermal cycling.
✓
Superior Bond Strength — C2-class tensile adhesion (≥1.0 N/mm²) after water immersion, heat aging, and freeze-thaw cycling for durable results.
✓
Natural Stone & Large Format Tiles — Specially formulated to bond heavy, low-porosity materials including marble slabs and large vitrified tiles.
✓
Interior & Exterior Applications — Weather-resistant formulation suitable for facades, external cladding, terraces, and all interior spaces.
✓
Extended Open Time (T-Class) — Non-slip T-class ensures tiles do not slide on vertical surfaces, combined with ample open time for accurate setting.
