Step 1: Assess the Damage

The first step is to assess the extent of the damage. Check for different kinds of imperfections in the wall. This step will help you determine what tools and materials you will need for the repair. For example, small holes may require spackling paste, while larger cracks might need patching compounds.

Step 2: Clean the Wall Surface

Before you begin the repair process, it’s important to clean the wall. Pollutants can prevent the paint from adhering properly. All you need is a mild detergent mixed with water to wash the wall surface. If there is any mould present, clean the area with a mixture of water and vinegar to remove it. However, it is essential to completely dry the surface before you go on to the next step.

Step 3: Remove Loose Paint

If the paint on the wall is peeling, it’s crucial to remove the loose paint sections before applying new paint. Use a paint scraper to scrape away the loose paint gently. However, it is essential not to dig too deep into the wall to avoid damaging it. Sand the area to make it smooth and well-prepared for the fresh paint. 

Step 4: Patch Holes and Cracks

When the wall is clean, it’s time to repair the issues with the wall. Crack fillers are enough for small holes, but for larger cracks, you will need a patching compound. Press the compound into the crack and smooth it with a putty knife. You may need to apply multiple layers, but it is important to allow proper drying time between the layers. 

Step 5: Sand the Surface

Once the filler or compound has dried completely, the next step is to sand the wall surface to ensure it’s smooth. Gently sand the patched areas and the rest of the wall. Sanding smooths the surface and makes it ready for a fresh coat of paint. After sanding, wipe the wall with a damp cloth or sponge to remove dust.

Step 6: Prime the Wall

Priming the wall before painting is an important step when you have a damaged surface to paint. A primer seals the repaired areas and provides a foundation for the paint to ensure better paint adhesion. Apply a coat of primer to the entire wall, and focus more on the damaged sections. Primer can prepare the surface and can also reduce the number of coats needed.

Step 7: Final Inspection

When the primer is dry, you can paint the wall. Before you start painting, do a final inspection of the wall. Look closely at the repaired areas to ensure they are smooth. If you notice any imperfections, touch them up with additional filler as needed. Inspect the wall properly and ensure it is fully ready for the painting process. 

Conclusion

In conclusion, it is essential to prepare a damaged wall before painting it. However, the preparation process needs proper understanding and attention to detail. You need to assess the damage and apply the right remedy. When you are sure that you have filled the cracks, you should prime the surface to ensure that it is fully ready for the fresh paint coat.
