Additional information


Product based on cement Tx® TECNO BIANCO 42,5R de FYM-Heidelbergcement Group, selected aggregates and additives.

Features and applications

  • It has a self-cleaning effect, breaking down biological dirt that adheres to the surface of the mortar and maintaining the initial aesthetic characteristics.
  • Reduces the concentration of harmful gases from urban and industrial pollution by breaking these down into harmless gases creating healthier environments with lower levels of pollution.
  • Acts on organic and inorganic pollutants such as NOx, SOx, O3, NH3, PM, benzene, VOC, etc.
  • There is no consumption of the photocatalyzers so the effect lasts for the useful life of the façade.
  • Indoors and outdoors application. 
  • Waterproof cladding.
  • Permeable to water vapour, allowing the substrate to breathe.
  • Excellent adherence and plasticity.
  • Smooth or sponge floated finish.
  • Apply by hand or with a pump.
  • Plaster and stucco works.


  • 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


  • Fix the optimum proportion water/mortar according to the chosen pump (section and hose length) and external weather conditions. Start with 16% 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).


  • 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.


Cautions and recommendations

  • The photocatalytic characteristics of self-cleaning and pollution neutralisation remain in the mortar provided that surfaces are not covered over.
  • The effectiveness of the photocatalytic processes is directly affected by the degree to which the walls built are exposed to light.  
  • 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 1,5 cm, it is advisable to apply the product in two coats.
  • In extreme weather conditions (strong winds or high temperatures) it is necessary to water the product with light sprinklers the day after applying it.
