AptiLith – 100% active lithium carbonate replacement for all fast set systems

AptiLith is a general purpose powder setting time accelerator and early strength enhancer for systems based on Portland cement combined with HAC or CSA cements.


AptiLith has been developed for fast setting cementitious systems where rapid fixing and laying is essential, such as:

  • Tile adhesives and grouts
  • Self-levelling floor screeds
  • Concrete repair systems


  • Dramatically accelerates setting times and increases early strength
  • It has a significant benefit over Lithium accelerators as it reacts with the Portland, HAC and CSA elements of cement mix
  • It is highly effective at a wide range of temperatures
  • Designed as a multifunctional accelerator for ternary systems and is recommended for use in formulations where lower Lithium Carbonate level are used


AptiLith should be added to the powder blender following the addition of sand and cement to ensure homogeneity.
