Final Performance    

  • Adhesion strength: 0.7 Ν/mm2– FP:B    
  • Compressive strength: 3.6  N/mm2 –  CSIII    
  • Water absorption: W1  
  • Apply with spatula in two or more coats if necessary. The first coat fills the roughness of the surface and the second makes the surface smooth.
  • Leave the first coat to set before applying the second one (the waiting time between the two coats should not exceed the 24 hours).   
  • Allow at least 24 hours, after the final coat, for curing. Before decoration, smooth out using fine sandpaper. The surface can then be decorated with a very wide range of paints and coatings like emulsion paint, acrylic-elastomeric paint, texture finishes.  

 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 a clean bucket containing water and mix with a low speed electric mixer until a homogeneous paste lump free is obtained. Attention! Additional water will make your mixture sloppy and may cause negative results on final strength.   
  • After mixing let the mix to stand for about 5 minutes and mix again for a minute.     
  • 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.
