Instructions for use

MECHANICAL APPLICATION:

  • Fix the optimum proportion water/mortar according to the chosen pump (section and hose length) and external weather conditions. Start with 18% 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).

MANUAL APPLICATION:

  • Add water and mix mechanically until it takes on an even and workable consistency.
  • Spread the mixed product over the substrate with the use of a trowel.
  • Spread to a thickness of no more than 0.8 cm.

To assure ensure good compatibility between the surface substrate and the coatings, take the following steps:

  • Wet the surfaces thoroughly at least 24 hours before applying, 
  • Cure the material applied for 24 hours after applying. 
  • Before finishing coatings with MORCEMCAL ACABADO, wait 24–48 hours per centimetre of mortar base coat.
