Additional information


Product based on high resistance cement, selected aggregates, and other additives.

Features and applications

  • White finish.
  • To be applied indoors and outdoors.
  • Waterproof cladding.
  • Permeable to water vapour, allowing the substrate to breathe.
  • Excellent adherence and plasticity.
  • For plastering on rough cast or applying in two coats.
  • Up to 1cm thickness. Non slip.
  • Smooth or sponge floated finish.




  • Conventional cement and brickwork based substrates.
  • Substrates must be resistant, stable, sound and clean, free of dust, demolding agents, organic products, etc.
  • In case of hot or windy weather conditions or when applying over absorbent substrates, it is advisable to wet the substrate and wait till the thin layer of water disappears.
  • With low-porosity substrates, apply a priming coat (IMPLAFIX) or improve roughness by mechanical means.
  • Do not apply on gypsum or on paint.          

Instructions for use


  • Add water and mix by hand or mechanically until it takes on an even and workable consistency.
  • Spread the mixed product over the substrate with the use of a trowel.
  • Let stand as long as necessary and then float finish.


  • Fix the optimum proportion water/mortar according to the chosen pump (section and hose length) and external weather conditions. Start with 20% proportion and modify it gradually until you achieve the appropriate consistency.
  • It is important to maintain the same variables affecting the features of the applied mortar (distance to the wall, angle of application and water proportion).

Cautions and recommendations

  • Do not apply below 5ºC nor above 30ºC.
  • Do not apply when there is a risk of frost, rain, strong wind or direct sunlight.
  • For a thickness of over 1 cm, it is advisable to apply the product in two coats.
