Features and applications

  • Direct application on the closing wall without filling.
  • Suitable for interior and exterior use.
  • Waterproofing cladding.
  • Permeable to water vapour, allowing the substrate to breathe.

  • Conventional cement-base or brick fabric substrates.
  • Substrates must be resistant enough, stable, healthy and clean.
  • Free of dust, release agents, organic products, etc.
  • In case of heavy heat, wind or very absorbent substrates, it is advisable to moisten the substrate and wait until the water film is totally absorbed.
  • In singular points (joints between different materials, slabs, pillars, shutter boxes, door and window frame angles, etc.) reinforce the mortar with fibreglass mesh to prevent cracks.
  • On slightly porous substrates, apply a suitable primer, or improve the roughness by mechanical means.
  • Do not apply on top of plaster or paint.

Instructions for use


  • Add water and mix manually or mechanically until getting a homogeneous consistence, easy to work with.
  • Spread the kneaded product on the substrate with the help of a trowel.
  • Spread the paste with a 12 mm and 15 mm thickness, after marking on site the cuttings by PVC beading.
  • For a good practice apply a 2-3 mm thick first hand, make sure it is well compacted, to seal the substrate, then lay the rest of the material.


  • Stablish according to the machine selected (section and length of hose) and external weather conditions or optimum water / mortar ratio.
  • Project the mortar onto the substrate, keeping the variables constant, as that may affect the characteristics of the applied mortar (distance from the wall, angle of application and proportion of water).


Scraping aspect.

  • Once the material has been applied, let it set for 4 to 15 hours, according to the type of substrate and environmental conditions.
  • Then, scrap the surface with a suitable tool (trowel with spikes, a saw, etc.).
  • To end up, brush the surface with a soft brush the following day to remove any spare particles.



  • Polish the hardened mortar partially to obtain a gradient colour result.
