Hydrated lime

Sparkguys HYDRATED LIME is a present-day step forward in the development of the lime industry. It is in the form of ready to use lime putty powder. It has a high water retention ability and plasticity. These account for the good workability of the lime mortars and the high adhesion effect to stone, concrete, ACC, ceramics, as well as to already solidified plaster surfaces.

The building-type mortar lime has well expressed disinfecting properties.The mortars and plasters made by it, after hardening, are very porous, enabling the breathing of the walls. In this way pleasant and healthy climate is created in the premises.

The Sparkguys Quality

Several factors are of gerat importance for the high quality of the Sparkguys Hydrated Lime:

  • The active oxides (calcium, and Magnesium) content – over 70% for the hydrated lime is a guarantee for its strength and plasticity.
  • It contains no unslaked particles – thus avoiding any danger of peeling off, bursts, cracks and deformation in the plastering.
  • Fine grinding and high yield of lime pulp per unit dry substance ensure its economical effect in using the product.
  • Whiter than white colour, of exceptional importance for decorative plastering and in painting.
