Plastering walls is one of the most fundamental steps in house construction and finishing. After the walls are built, the mortar must be carefully mixed and applied smoothly and correctly to ensure both the aesthetics and durability of the house. This is a crucial stage that significantly affects the final appearance of the house. When plastering, every small detail must be handled with precision.

PREPARATION WORK

  • Wall plastering is carried out after the installation of embedded pipes, cables, and other concealed systems is completed.
  • For areas with two or more embedded electrical conduits, a wire mesh should be applied to reinforce the surface.
  • The wall surface should be leveled using the screeding method before plastering.
  • Before applying plaster, the surface must be thoroughly cleaned to ensure a strong bond between the mortar and the wall.
  • Use INSEE cement within its shelf life and store it according to proper standards.
  • The sand used must be carefully sieved to remove impurities.
  • The plaster mix (cement + fine sand + water) must be prepared in the correct ratio.

TECHNICAL REQUIREMENTS AND METHODS

  • The plaster layer for ceilings should be between 10mm and 12mm thick. If a thicker layer is needed, reinforcement measures such as wire mesh or multiple thin coats should be applied to prevent cracking.
  • Apply plaster in thin layers, allowing each layer to dry before adding the finishing coat. Use an aluminum straightedge to smooth the plaster from bottom to top. Any depressions should be filled with additional mortar using a trowel.
  • Once the surface is leveled, allow the plaster to set slightly before using a wooden float to smooth it. Start with broad, firm strokes, then gradually refine with smaller, lighter strokes. Finally, lift the float gently away from the surface while smoothing.
  • Ensure that all horizontal edges are straight, all corners are square, and no cracks, bumps, or uneven areas are present.
  • Cure the plastered surface by keeping it moist to allow the mortar to develop full strength.
