Features and applications

  • To be applied directly on the brickwork. No need for a previous plastering.
  • To be applied indoors and outdoors.
  • Waterproof cladding.
  • Permeable to water vapour, allowing the substrate to breathe.
  • No cracking.
  • Wearing resistant. Fading resistant.
  • No paints necessary. Excellent façade finishes in just one application.
  • Agregage projection finish
  • DIT PLUS N·379p


  • 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.
  • In particular points (union between different materials, top slabs, pillars, roller blind boxes, angles in the door and window frames, etc.), prepare the mortar with glass fibre mesh to avoid fissures.
  • With low-porosity substrates, apply a priming coat (IMPLAFIX) or improve roughness by mechanical means.
  • Do not apply on clay 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.
  • The mixture must be extended with a thickness of 12-15 mm, after marking the pieces by using PVC splines.
  • It is advisable to apply a well compacted first layer of 2-3 mm to seal the substrate, and then spread the remaining material.


  • 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).


  • Finish with projection of aggregate. 
  • Once the surface has been levelled and before the superficial coat is dry, apply the chosen aggregate and press with the trowel to achieve the same level for aggregates and mortar.

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.
  • Due to changes in the raw material, the one-coat mortar tone might slightly vary from one batch to another.
  • Stone to be projected should be dry and free of dust.
  • It is not advisable to apply on horizontal or sloped surfaces.
  • For a thickness of over 2 cm, it is advisable to apply the product in two coats.
  • The final minimum thickness should be 10 mm.
