Final Performance    

  • Adhesion strength: 0.5 Ν/mm2– FP:B    
  • Compressive strength: 9.8N/mm² - CSIV      
  • Thermal conductivity (λ10,dry): 0.4 W/m∙K - standard table value  
  • Apply by hand using a trowel in two crossed coats of 2-4 mm. The 2nd coat is applied only when the first one has been set.    
  • The final surface may either be finished with a trowel covered with sponge or made smooth with a steel trowel’s edge. The surface should be lightly dampened, for 2–3 days, beginning 24 hours after application, especially in hot weather, with intense evaporation.  

Substrates Preparation   

  • The substrate must be solid, free of dust, loose parts and oils.    
  • The substrate has to be flat without any anomalies for better final appliance.   
  • 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.    
  • 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 because it might have adverse effect on its mechanical properties. In such case the mix should be dropped.
