Before diving into renovating the walls of an old house, it's crucial to assess the extent of damage. Cracks, water seepage, or peeling paint may necessitate significant overhauls involving structural modifications and waterproofing. However, for minor issues like surface stains or slight peeling, the process is simpler: remove damaged areas, apply cement for leveling, skim-coat, and then repaint or install wallpaper. Thus, understanding the wall's condition beforehand is paramount.

1. Assessing Wall Damage

Prior to renovation, a thorough examination of the walls is necessary. Check for cracks, water seepage, or extensive peeling. Major repairs might involve restructuring and waterproofing. For minor issues such as surface stains or light peeling, removal of damaged areas, cement leveling, skim-coating, and painting or wallpapering are sufficient.

2. Thorough Cleaning of Walls

Before renovating old walls, ensure they're thoroughly cleaned. Severe powdering requires complete removal followed by a layer of white cement. If walls have been previously painted and are smooth, sanding is necessary to enhance adhesion with new coatings.

3. Application of Primer

Applying primer is essential before renovating walls. It enhances alkaline resistance, moisture protection, and adhesion to topcoats while improving texture and coverage. Failure to apply primer may lead to issues like blistering, mold growth, or discoloration over time.

4. Maintaining Consistent Color

During wall renovation, ensuring color consistency is vital. Strict adherence to paint manufacturer's instructions for mixing and application is necessary. Sufficient paint quantity should be prepared to prevent color discrepancies due to remixing.
