Instructions for use

  • With the help of a mixer, stir the product to ensure its homogeneity.
  • Minimum 24 hours after placing the reinforcing profiles and after the hollow corners (windows and doors) have been reinforced with MALLA TRADITERM (40x20cm), spread on the insulating panel a layer of TRADITERM FLEXIBLE mortar and comb it afterwards with a notched trowel (6mm).
  • Onto the combed r mortar, spread, from up to down, the MALLA TRADITERM, and squash the furrows pressing with the trowel. Cover the mesh with the protruding TRADITERM FLEXIBLE mortar. Even if the mesh is fully covered, the grids should be marked. This layer should have around 1,0-1,5 mm thickness.
  • Meshes should be overlapped with a minimum of 10cm.
  • Once the layer has gained a certain resistance (3-4 hours after), a new TRADITERM FLEXIBLE mortar layer of 1,0 mm will be applied in order to cover the grids of the mesh and finish the coated surface.
  • After 72 hours minimum, we will proceed with the decorative finish, applying FONDO MORCEMCRIL and any of the following claddings afterwards: MORCEMCRIL (MORCEMCRIL, MORCEMCRIL SILOXANO, MORCEMCRIL FLEXIBLE  or MORCEMCRIL MOSAICO).
