Mechanized application: First apply a spray of the same material, adjusted to a water content of 22% -24% and allowed to cure for 24 hours. After complete and complete drying of the spray, the mortar is applied to the final thickness, with a mean thickness per layer of 2.0 cm. Beyond the concrete, wood, or other non-absorbent beams, a reinforcement mesh will be inserted into the mortar. Manual application: Applies in a classic manner to the wall, following the same processing steps as in the case of mechanized application.
