  • Resists up to 350°C.
  • Exterior and interior use.

Descriptive Memory

The fixing and assembly of refractory bricks shall be carried out with ARGOTEC REFRACTARIO refractory mortar, from the Argos cement derivatives company. The laying substrate shall be sound, clean, free of friable parts, completely hardened and shall have reached the end of its dimensional variation time.


  • Refractory bricks.
  • Other substrates in contact with high temperatures (consult Technical Department).
  • Terracottas.

Substrate preparation

  • Metal elements, such as reinforcement, must be free of rust, dust, mortar residues or other materials that may impede adhesion or contribute to corrosion.
  • The substrates must be clean and sound, free of grease, paint or other substances that would prevent proper adhesion.
  • A suitable adhesion primer shall be used on low-porosity surfaces.

Instruction for Use

  • Knead ARGOTEC REFRACTARIO with 800 mL of clean water per 5 kg bag manually or mechanically until a homogeneous, creamy and lump-free mixture is obtained.
  • Spread the mixture on the substrate or on the workpiece using a trowel.
  • Place the workpiece on the fresh mortar layer and press down.
  • Level with the trowel and proceed with the grouting.


  • The commissioning of the work shall occur at least 7 days after its execution, warming up gradually.
  • Do not apply when there is a risk of frost, rain, strong wind or direct sunlight.
  • Do not apply below 5°C or above 30°C.
  • Do not apply to plastic, metal, wood, rubber, etc. surfaces.
  • Do not add more water once it has started to set.
  • Protect the cool surface from direct sun, rain and especially draughts.

Handling, storage and preservation

  • It is packaged in 25 kg multi-leaf paper bags with damp-proof sheets and in 5 kg plastic bags that allow it to be stored for 12 months in its original sealed packaging, safe from dampness.

Cleaning of Work Tools

  • If the product is fresh, with water
  • If the product is dry, scraping
