Tiles Adhesive
SUPER TAJ SHREE
White STAR (ST-225)
Polymer modified tile adhesive
DESCRIPTION
Polymer modified grey & white cement-based adhesive, suitable for fixing ceramic tiles for floors & walls in interior situations. Suitable for fixing ceramic tiles upto 6 mm bed thickness (can be extended up to 12 mm thickness in area of limited extent). The set adhesive is water-resistant and is suitable for use in showers and bathrooms.
Note: Not recommended for direct use onto gypsum plaster (wall finishes), paint or metal

Coverage:
Approx. 35-40 sft per 20kg bag with 1/4” x1/4”

Bed of 3mm.
Coverage will vary depending on trowel notch size,type and
Size of tile and substrate smoothness and evenness.
APPLICATION INSTRUCTIONS:
Substrate Preparation
Before starting any work ensure that the base is:
Sufficiently flat to permit the specified flatness of finished tiling, bearing in mind the permissible thickness of the adhesive.
Suitable for tiling in the service conditions to which it will be exposed.
Surfaces to be tiled must be dry, clean and free from loose material and contamination.
SITE WORK INSTRUCTIONS
Surface considerations
New Cement Sand rendering/Brick/Block Wall: Before commencing tiling, allow plastered surface to air dry for atleast 2 weeks.
New Concrete Bases: Before commencing tiling, ensure that bases have been allowed to air dry for at least 4 weeks
Mixing
Add White STAR to clean water. Mix thoroughly until a lump-free mortar is obtained. A 20 kg bag will require approx. 3.55 – 3.65 litres of water to obtain a slump-free consistency. The adhesive is immediately ready-for-use and has a pot life of 3 hours. No further water should be added. Where mixing by weight is not possible, volume mixing can be carried out at site in the ratio of 1 : 3 (water : powder)
APPLICATION
1. Spread not more than the area which can be tiled within the open time of the adhesive.
2. The mixed adhesive is applied to the prepared surface with a trowel and then combed through with a suitably sized square toothed notched trowel.
3. The tiles should be fixed within the open time of the adhesive and pressed into place with a twisting and sliding action ensuring solid bed fixing is achieved. The open time is dependent on site conditions and will be extended in lower temperatures and shortened at higher temperatures.
4. Check periodically that good contact is maintained with the back of each tile.
5. Touch the adhesive ribs periodically and if a skin has formed,remove the adhesive and apply a new layer.
6. Leave adequate joints between individual wall and floor tiles unless self-spacing tiles are used.
7. Clean off surplus adhesive from the tile face and between joints

7. Clean off surplus adhesive from the tile face and between

SPACERS
Use supertaj spacers for uniform joint width.
GROUTING
Grouting should be carried out after 24 hours of tiling. Use the appropriate grouting material from the range of cementitious and epoxy grouts.
Note: The addition of ADMIX GT1 to cement – based grouts will enhance adhesion to tile edges, increase water resistance and improves flexibility.
CLEANING
Tools and containers may be cleaned using clean water when the adhesive is still fresh. The hardened adhesive can be removed from tools mechanically
STORAGE AND SHELF LIFE
White STAR has a shelf life of 12 months when stored in normal dry conditions.
PRECAUTIONS
Keep out of reach of children. Wear suitable protective clothing, gloves and eyes/face protection. After contact with skin, wash immediately with plenty of clean water. In case of contact with eyes rinse immediately with plenty of clean water and seek medical advice. For more details please refer the relevant Material Safety Data Sheet
