Stone Adhesive
PATRAWALA-SM Stone Adhesive is a pre-mixed, ready-to-use adhesive compound with a grey base and high-quality silica (SiO₂ 98%+), cement, and adhesive components. Designed for both internal and external applications, it ensures consistent quality for all types of natural stone fixing. PATRAWALA-SM is a single-component, water-resistant bonding mixture ideal for civil construction projects.
PATRAWALA-SM can be used for various types of
in accordance with IS 13712: 2006. Suitable for flooring and walls in both internal and external areas, it is effective in dry and wet conditions for domestic and commercial applications.
High Compressive Strength: Achieves compressive strengths of 12.1–14.5 MPa in 2 days, 19.1–23.8 MPa in 7 days, and 34.1–36.9 MPa in 28 days, depending on the aerogel content ratios and activator dosages.
Easy Application: Pre-mixed material requires only the addition of water on-site, simplifying and speeding up the stone fixing process.
Self-Curing Properties: The silica-based compound ensures low temperature of the bonding agent and fast curing, allowing hassle-free application with minimal labor.
Better Coverage: Provides efficient and effective coverage for various applications.
Eco-Friendly: Contains no fly ash or slag.
Clean the surface to remove oil, bond inhibiting agents, dust.
20% to 22% of water by weight of material
Stirring for 3 minutes till it's free of lumps
Leave the mix to react for 5-10 minutes before use
Apply adhesive on both surfaces using notch trowel
Place the tiles on the surface then move it in perpendicular direction to notches
Tap the gently using wooden or rubber mallet
Remove the excess adhesive using damp cloth / sponge
Wait 24 hours for subsequent application
Prevent direct contact with skin and eyes. In case of contact, wash with clean water immediately
