  • WALL TILE ADHESIVE KJ & KJ+
Description
UNIV®-KJ is a premixed, ready-to-use, grey silica-based (SiO2 98%+) cement adhesive compound designed for all types of wall tile applications, both internal and external. This high-quality, single-component, water-resistant bonding mixture ensures consistent quality and is composed of pure fine mesh silica, cement, and adhesive compounds, ideal for civil construction sites.
 
Reference Standard
  • IS:15477
  • EN-1348
Area of Application
UNIV®-KJ is suitable for various applications, including:
  • Wall ceramic tiles
  • Vitrified tiles
  • Natural stones
  • Marble, granite, terracotta
  • Large format tiles
  • Porcelain (as per IS 13712:2006)
Ideal for flooring in internal and external areas, dry and wet areas, and both domestic and commercial applications.
 
Benefits
  • High Compressive Strength: Mortar specimens exhibit compressive strengths of 12.1–14.5 MPa at 2 days, 19.1–23.8 MPa at 7 days, and 34.1–36.9 MPa at 28 days.
  • Easy Application: The premixed material requires only the addition of water on-site, simplifying and speeding up the tile-fixing process.
  • Self-Curing Properties: Due to the silica base, the bonding agent has a low temperature and fast curing time, facilitating 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®KJ & KJ+ 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®-KJ requires 20% ofNormal Water by weight of material (Example- 20kg Bag requires 4.0 to 4.5 Litre ofWater)
Mix UNIV®-KJto the measured quantity of water using mechanical stirring for 2-3 minutes to ensure a consistentlump free mixture
 
Application- UNIV®-KJ on both surfaces using 6 mm notch or mortar trowels spatula.
Place the tiles on the surface then move it in perpendicular direction to notches.
Tap the tiles 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 24Hr.
 
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.
