  • Highly suitable for fixing all types & sizes of natural marble which are not sensitive to moisture.
  • Best to use inside swimming pool and best to fix high-quality glass mosaic application.
  • High polymer content.
  • Far exceed the strength of class C2 TE adhesive as per European norms.
  • Fully thixotropic (Slip < 0.5mm.) for wall application and for the big format of tiles & marble.
  • The extreme White colour of adhesive for natural marble and transparent glass mosaic.
  • Long-life assurance of performance.
  • No water curing required.
  • Very High coverages with a minimum thickness of 2 mm. and maximum up to 15 mm.
  • No need to mix any extra cement or sand. Ready to use.
  • Very low VOC and suitable for green building points
    Suitable Areas:
  • Internal & external wall & floor.
  • Residential & commercial buildings.
  • Public infrastructure projects including swimming pools and water tanks.
  • Industrial facility
Suitable surfaces:
  • Full dry and sound new or old traditional plaster.
  • New or old absorbent IPS or PCC floors which are sound and stable.
  • Screed made with Zeorich Base, Zeorich Base Rapid, or similar kind.
  • Fully cure stable concrete of all types including machine cut concrete block and fly ash brick.
  • Existing tiles or stone surfaces.
  • Gypsum based plaster, screed or AAC block, Panel (Autoclaved Aerated concrete). Apply primer before use
Suitable covering material:
  • All kind of natural stone which are not sensitive to moisture include slate stone.
  • All types & sizes of ceramic & glass mosaic.
  • All types & sizes of ceramic & vitrified tiles.
  • Large-format tiles of all type including a vitrified thin slab of 3mm
Surface Preparation:
  • Ensure that surface is sound, clean and free from all foreign material such as oil, grease, dust etc.
  • If the surface is uneven of more than 15 mm. than first do the levelling by using correct levelling material in order to avoid using the excess thickness of adhesive or apply a first thin coat of the same adhesive to level the surface and wait for 24 hours.
  • Onto dry clean surface, splash enough water, and let it surface dry to improve the workability of adhesive.
  • In case working on an external façade, avoid direct sun exposure to the surface and to finishing material. Let cool the surface before starting the application. A hot surface may compromise final performance.
  • If the surface area is larger, provide movement joint every 3 meters.
  • Follow the concrete expansion joint and connection joint as per standard.
  • Mix Calcibond Flex 20 kg. grey with approx. 5.8 lt. and white with 6 lt. of clean water. Use slow speed electric stirrer for mixing to have desirable results. Manual mixing can compromise the performance of adhesive.
  • Adjust the water quantity as per ambient temperature and dryness of surface. The final mix must be a workable paste.
How to apply:
  • Spread the adhesive in desire thickness from 2 to 15 mm. onto the base surface using Wallnut notch trowel.
  • Once adhesive is applied, fix the tiles or stone onto adhesive before skin formation and press firmly. In case tiles or stone are of big size, also apply the adhesive layer at the back of the tiles.
  • Leave the space between tiles or stone to have proper grouting and to accommodate surface movement.
  • Leave the tiles or stone for 24 hours to bond well and then follow the grouting process.
