  • Application temperature: +5 ºC - +35 ºC    

Final Performance    

  • Adhesion strength: 0.2 Ν/mm2– FP:B    
  • Compressive strength: CSI    
  • Water absorption: W0     
  • Thermal conductivity (λ10,dry): 0.25 W/m∙K                                                      
  • In the surface area usually we put special wood wedges.   
  • Application can be done using level guides (10-30mm) by either a trowel or a float.   
  • The plastered surface remains workable for a few days, if sprayed with water immediately before. Then rub with a wooden or plastic flat. Next day the surface is perfected, immediately after spraying with water.   
  • Keep the surface wet for at least 30 days, especially in hot weather.   
  • For practical reasons LIME PLASTERED surfaces should remain unpainted for several months.

Substrates Preparation

  • The substrate must be solid, free of dust, loose parts and oils.
  • Cracks or cavities are suitably filled and allowed to cure, before lime plaster application.
  • To avoid immediate absorption of mix water by the substrate and for better adhesion saturate the surface to provide a saturated surface dry condition.

 

Preparing the mix 

  • Pour the material into clean water and mix (mix in a concrete machine for big quantities or with a low speed electric mixer for small quantities) until a homogeneous lump free mix is obtained.   Allow mixture settle for 5 minutes prior the application. Attention! Additional water will make your mixture sloppy and may cause negative results on final strength.
  • Mixing period should not exceed 5 minutes because it might cause adverse effect on its mechanical properties.
  • Use the mixture when is still fresh. Do not leave the mix unmixed for a long time.
  • Do not mix with water or latex additive when the mixture starts to set in the bucket. In such case the mix should be dropped.
