AptiLith Halda

AptiLith Halda is a free-flowing powder additive based on high molecular weight copolymers, functions as a highly effective water retainer and rheology modifier for bagged mortars.


AptiLith Halda has been specifically designed to provide high levels of water retention, sag resistance and longer open times in a wide range of applications including:

  • Tile adhesives and grouts
  • Renders
  • EIFS mortars
  • Repair mortars
  • Bricklaying mortars


Whilst dosage is dependent on a range of factors including mix design, raw materials and end application, users should consider the performance required in terms of water retention and anti-slump requirements.
