Cleaning: The surface must be free from dust, dirt, oil, paint residues, and other contaminants. The surface should be cleaned using a brush, broom, or air blower. Crack and Hole Inspection: Cracks and holes on the surface should be inspected, and if necessary, previous repairs or loose materials should be removed.
Water Drainage: If water accumulates on the surface to be treated, it should be drained or dried. Excess water content may affect the quality of the application.
Surface Smoothing: If there are rough areas or protrusions on the surface, they should be corrected. The surface can be smoothed using a spatula or an appropriate tool.
Primer Application (Optional): In some cases, applying a primer to the surface may be important to ensure better adhesion of the cement-based repair mortar.
Surface Moistening (Optional): If the surface is very dry, it can be moistened to improve the adhesion and curing properties of the cement-based mortar. However, an excessively moist surface can also create adverse effects, so balanced moistening is important.
