Detailed Methodology

Preparation
- Clean the wall surface to remove dust.
- Apply an acrylic fixative to neutralize dust on the surfaces.
Materials
- Use a small-grained mortar based on white cement for exterior use.
- Employ fiberglass mesh to treat cracks in the wall.
Crack Treatment
- Cut strips from a fiberglass mesh roll (or use pre-made small rolls).
- Apply a layer of smoothing compound over the cracks.
- Place the fiberglass mesh over the compound, then cover it with another layer of smoothing compound.
Applying smoothing compound
- For deep holes, use a specific product (costing around 2 euros).
- Level the entire surface using a mortar called "ras preview fix," applied with an American trowel up to 3 mm thick.
- Ensure the first coat is applied evenly before it dries completely.
Second Coat Application
- Apply the second coat of smoothing compound while the first coat is still slightly humid.
- Use a small spatula to remove any rough strips from the first coat before applying the second coat.
Finishing Touches
- Use a sponge trowel for finishing the surface, which should be done when the mortar is still wet.
- Wet the applied mortar with water before finishing to achieve a smooth texture.
Final Steps
- Allow the mortar to dry completely before painting (which may take up to 45 days).
- If dust is present from other renovations, apply a fixative before painting.
