Installation
Installation
Instructions
Application Instructions
-
Clean the surface
-
Surface saturation with water (SSD condition)
-
Add water first
-
Add LX-7 Superflex S2 (Grey/White) powder to water
-
Mix it with a mixer
-
Check material consistency
-
Waits mins. and remix before use
-
Spread adhesive with a notch trowel
-
Back buttering
-
Place tiles within open time
-
Move tile opposite to notches & tap gently
-
Fill joints with Gresbond KE-100 Premium Epoxy Grouts
Substrate Prepration
-
The substrate must be levelled,cured, undamaged,compact, rigid, resistant,dryand free from any debonding agents and from damp rising.
-
All surfaces must be plumb andtrue to within 2-3 mm in 10ft (3m).
-
Dry, dusty surfaces shouId be dampened with water & excess water shouId be swept off.
-
New concrete slabs shall be damp cured and 28daysold before application which will reduce the shrinkage from tile fixing surface.
-
Expansion joints to be provided & fiIled with suitable sealant. Do not cover expansion joints with thin settile adhesive/tile
Mixing
-
Add 5 to 5.5 litres water for 20 Kg powder in a clean mixing vessel.
-
Adjust the water as per desired consistency.
-
Mix with a suitable mechanical stirrer or slow speed drills (50-100 rpm) until a lump-free homogeneous paste is obtained.
-
Always mix the required quantity, which can beconsumed within pot life.
-
Leave the mixture for 5 minutes before use.
-
No further water shouId be added.
Precaution & Notes
-
Always add powder to water
-
Do not add excess water than recommended.
-
Never add sand & cement at the site.
-
Do not use on wet screed. Surface must be fully cured.
-
Do not use the adhesive to correct surface irregularities greater than 15 mm.
-
Protect from direct rainfall/foot tractor at least 24 hours.
-
Designer/applicator must evaluate the use of an additional mechanical fastening system for extra security for more than 3m height (such as steel hooks fastened to the substrate).
-
For large format tiles or stone, spacers are recommended.
-
Movement joints should be provided at every 3m specially to accommodate contraction/expansion and filled with a flexible sealant.
Application
-
Apply adhesive to the substrate with the flat side of the trowel.
-
Comb on additional adhesive with the notched side.
-
Use the proper sized notched trowel to ensure full bedding of the tile.
-
Tiles must be fixed within 30 minutes of adhesive being applied, depending on the porosity of the surface and atmospheric conditions.
-
Check the adhesive ribs periodically and if a skin has formed, remove the dried adhesive and apply fresh adhesive.
-
Press the tiles firmly into position with a slight twisting action, checking periodically that good contact is maintained with the back of each tile and beat in using a rubber mallet to embed tile and adjust level.
-
Leave no voids behind tiles.
-
For large-size tiles or irregular surfaces, adhesive can additionally be buttered on the backs of the tiles to ensure full adhesive contact.
-
Use suitable support along with adhesive for fixing tiles on vertical surfaces.
-
For highly absorbent natural stones which may form a wet patch when adhesive is used, it is recommended to use a suitable impregnating sealer on all sides. Please refer Technical Data Sheets of product intended for use for specific instructions of use.
-
For highly absorbent surfaces like drywalls, consult with GRESBOND technical team.
-
Leave adequate joints between individual wall and floor tiles using GRESBOND spacers. The joint width shall be as per the recommendation of the architect/engineer.
-
Clean off surplus adhesive from the tile face and between joints.
-
Clean tools and tile work with water while adhesive is fresh.
Coverage
- Approx. 4.5–5.5 m²/20 kg Bag at 3mm thickness (using 6mm x 6mm notch).
- Approx. 2.5–3 m²/20 kg Bag at 6mm thickness (using 12mm x 12mm notch).
- Approx. 1.2 kg/m² per mm of thickness
*Coverage will vary depending on trowel notch size, type, the size of tile and substrate smoothness and evenness.
Grouting
-
Grouting should be carried out after 24 hours of tiling. Use the appropriate grouting material from GRESBOND range of cementitious and epoxy grouts.
- 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. Limited to professional use only.
- For more details please refer the relevant Material Safety Data Sheet, available on request.
