Cleaning: The surface must be cleaned of dust, dirt, oil, paint residues, and other contaminants.
Repair and Correction: If there are cracks, holes, or other damages on the surface, these areas should be repaired using a suitable surface filler or plaster.
Surface Smoothing: Unnecessary protrusions, bumps, or roughness should be removed to achieve a smooth surface. This helps the plaster to be applied more evenly.
Surface Primer and Base Coat: The surface can be treated with a primer or base coat. This enhances the bond between the plaster and the surface, improving application performance.
Water Permeability and Adhesion Test: The water permeability and adhesion properties of the surface should be tested before applying the plaster. These tests can enhance the durability of the application.
Leveling and Alignment Work: Slopes, roughness, or irregularities on the surface should be corrected before applying the plaster.
Surface Moisture Content: The moisture content of the surface should be checked. Moisture can affect the application of the plaster, so appropriate moisture levels must be maintained.
Expansion Joints: Expansion joints should be considered for large surfaces or between different materials. This provides resistance to thermal expansion.
