  • Gray version made of sulphor-resistant cement.

Descriptive Memory

The rendering of the walls will be carried out with ARGOSEC® M-25 ÉLITE dry mortar from the company DANOSA, class GP CSIV according to the UNE EN 9981 standard. The substrate must be sound, clean, free of friable parts, completely hardened and have completed its time of dimensional variation. The construction joints shall be respected


  • Insulation panels.*

Substrate preparation

  • The substrate must be clean, dry, dust-free, free of oil, grease, surface laitance or other elements that impede adhesion such as old waterproofing membranes or other coatings.
  • The substrate shall be dry, clean, compact, free of dust and separating agents.

Instruction for Use

  • Mix ARGOSEC® M-25 ELITE with 4.75 L of clean water per 25 kg bag manually or mechanically until a homogeneous, creamy and lump-free mixture is obtained.
  • Spread the mass on the piece with the help of a trowel or spray on the walls and/or ceilings.
  • Once the required level of thickness has been reached, spread the mixture on the piece with a trowel or spray on the walls and/or ceilings.


  • Store in a dry place, protected from rain, sun, high and low temperatures.
  • Consult the safety data sheet.
  • It is advisable to mesh the application at singular points.
  • When applied at very high relative dampness, drying may be delayed.
  • In case of splashes in the eyes, rinse with plenty of water and seek medical attention if necessary. For more detailed information see safety data sheet.
  • Do not apply when there is a risk of rain or frost.
  • Do not add more water once it has started to set.
  • Comply with the mixing water.
  • On very porous substrates prime with DANOPRIMER® RPU.

Handling, storage and preservation

  • It is packaged in 25 kg multi-leaf paper bags with damp-proof sheets that allow it to be stored for 12 months in its original sealed packaging, safe from dampness.

Safety and hygiene

  • Consult the safety data sheet.
