UNIV®-SM Stone Adhesive
 
Description
UNIV®-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. UNIV®-SM is a single-component, water-resistant bonding mixture ideal for civil construction projects.
 
Reference Standard
  • IS:15477
  • EN-1348
 
Area of Application
UNIV®-SM can be used for various types of
  • Ceramic tiles
  • Bricks
  • Vitrified tiles
  • Natural stones
  • Marble
  • Granite
  • Terracotta
  • Large format tiles
  • Porcelain
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.
 
Benefits
  • 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.

How toApply: -
Surface Preparation
Prepare the surfaces before the UNIV®-SM application by removing oil, bond inhibiting agents, dirt, dust and laitance
The cleaning can be carried out with suitable methods like by using wire brush, water jetting,mopping, etc.
 
Mixing
UNIV®-SM requires 20% ofNormal Water by weight of material (Example-20kg Bag requires 4.0 to 4.5 Litre ofWater)
Mix UNIV®-SM to the measured quantity of water using mechanical stirring for 2-3 minutes to ensure a consistentlump free mixture
 
Application- UNIV®-SM on both surfaces using 6 mm notch or mortar trowels spatula.
Place the stone / marble on the surface then move it in perpendicular direction to notches.
Tap the stone / marble gently using wooden block or rubber mallet. Remove the excess adhesive using damp cloth / sponge.
 
Curing
Due to Silica Base compound the temperature of bonding agent low & it gives fast curing, Its Required time for Settlement is 24 Hr.
 
Precaution –safety
As per health & safety rules. Use safety accessories required to be used, would include:
a) Safety gloves
b) Safety goggles
c) Dust & nose mask
d) Helmet
 
In case of accidental contact with eyes of either dry or wet mix, immediately wash your hands; make sure your hands are clean and then wash your eyes with clean water and if required, seek medical assistance.
 
Avoid breathing dust.
