  • White and Grey 
  • Easy to use, just add water.
  • High bond strength
  • Water & Weather resistant.
  • Good flexibility , so it is suitable for use on facades
  • Good pot life.
  • Non toxic


The surface to be tiled should be sound, dimensionally stable, clean and free from dusty or friable materials, paint, grease, oil etc.


  • Thin-bed fixing: 
    2 – 3kg/m² (Smooth surface using notched trowel)
  • Solid-bed fixing:
    5 – 6kg/m² (Smooth surface using notched trowel)


Mix FLEX – C 1 slowly in clean and sweet water (approx. 4 – 5 liters) until a smooth & lump-free mixture is obtained.
Leave to stand for 15 minutes then stir. Don’t add further water.


1- Apply FLEX – C 1 to a minimum depth of 3mm on a working area of not more than 1m². (See Note 1)

2- The adhesive bed should be combed horizontally with a notched trowel to remove excess.

3- Fix dry tiles by pressing into place with slight twisting motion (See Note 2)

4- Ensure that at least 65% of each tile is in contact with adhesive.

5- Clean off surplus adhesive from the face of the tile with a damp cloth. Similarly, joints must be raked out in readiness
for grouting.

6- Leave for a minimum of 24 hours before grouting.

1- Solid-bed fixing is recommended for wet conditions, Terrazzo and Marble flooring tiles and vertical heavy duty applications including decorative Stone cladding. But unlike the application of ordinary tiles, apply to the cladding itself and not to the substrate. For best results, allow no more then 35 kilos weight of stone cladding (of average thickness 10mm) per square meter.

2- Fix tiles (which should be dry) by pressing into place. Beginning at the bottom in the case of wall tiles and at center
markings in the case of floor and pool tiles.


► FLEX C – 1 should not be used on painted or metal surfaces.
► The use of chilled water while mixing, will extend open wet time in high ambient temperatures.


Working time of FLEX C – 1 is about 45 minutes at 25°C, after 30 minutes standing time and tiles must be fixed in position before drying out occurs. For this reason, it is essential to work with in a comparatively small area at a time.


FLEX C – 1 is available in Grey & White Colours. 


FLEX C – 1 is available in 20kg bags.
