This problem is more common than it may seem, and although it may seem daunting, I assure you that repairing and repainting peeling paint on interior walls is much easier than you think.Let's do it together! Here I will guide you step by step so that you can give your walls back a flawless look you want so much by repainting.

Why does the paint peel off the interior walls?

Before embarking on the work, it is important that we understand why the paint is peeling. Know this will help prevent future problems once you repair and repaint the wall. and affected areas. Some of the most common reasons are:

  • Moisture: This is the number one enemy of paint. If there is water seepage or condensation behind the wall, the paint will start to peel.
  • Poorly prepared surfaces: If the wall was not properly prepared when it was painted, the paint may not have adhered properly.
  • Paint quality: Poor quality paint or paint that is not suitable for the type of surface can easily peel off.
  • Natural wear and tear: Over time, it is normal for painted walls to suffer from wear and tear, especially in high traffic areas.

Step-by-step to repair paint peeling in interiors

We know that looking at that wall can be frustrating, but don't worry! With a little patience and following these steps, by repaint, your walls will look as good as new.

  1. Assess the affected area

    The first thing you should do is carefully examine the area where the paint is flaking off. Feel the wall and check if the area is damp. If you notice dampness, you will need to solve that problem before proceeding. This may involve sealing leaks or repairing pipes.
  2. Clean and scrape off loose paint

    Once you are sure that the wall is dry, begin by gently scrape off loose paintwork. You can use a spatula or a special paint scraper. Make sure to remove all loose fragments. until you reach a firm surface.
  3. Sand the surface

    After scraping, you will notice that the wall is not completely smooth. To correct this, use a fine-grit sandpaper (you can use 180 to 220 grit sandpaper) and smoothes the edges of the area where the paint has peeled off. The idea is to achieve a smooth transition between the old paint and the repaired areaso that no irregularities are noticeable once you paint.
  4. Fills cracks or imperfections

    If the wall has cracks or small imperfections, this is the moment to fill them with Tecpint special wall putty. Apply the putty with a spatula and then smooth it out well.. Wait for it to dry according to the manufacturer's instructions.
  5. Priming: The step you can't skip

    This is one of the most important and often forgotten steps. Apply a coat of primer to the repaired area. The primer helps the new paint adhere better to the wall and prevents the problem of peeling. If this happens again, you can use Tecpint Primer or Tecpint Primer Gel. It also seals the surface and ensures that the final finish is uniform. If using ecological paints, use Tecpint Consolidante al Silicato.

Repainting the interior wall

The most awaited moment! Now that the wall is ready, you can repaint the peeling paint on the wall, it is time to choosing a good interior paint. I recommend that you use high quality products such as the Tecpint range of paints, which are specifically designed for durability and a flawless finish. Within this range you can find:

If you want to colour the paint

If you want to change the colour of any of the paints, use WATER-BASED LIQUID DYES in the colour of your choice, this will not affect the thermal and breathable properties of the products.if you want to change the colour and if your problem is humidity or condensation, never apply plastic paints over breathable paints.They will stop sweating and the plastic paint will peel off.

Tips on how to apply paint when repainting walls

For a professional finish, I suggest you apply two coats of paint.. Wait for the first coat to dry completely before applying the second coat for the time indicated by the manufacturer. In this way, you will achieve perfect, long-lasting coverage. If you use thermal paints and your objective is thermal insulation, apply a third coat.

Tips for a perfect finish

  • Don't rush: Make sure each coat is completely dry before moving on to the next one, paying attention to the drying time indicated on the label or manufacturer's instructions.
  • Use the right tools: A good quality roller will help you avoid unwanted marks or lines.
  • Take care of the details: Use a small brush for edges and corners, making sure to cover all areas well.

  • Control humidity: If your house tends to be damp, use breathable paints, use dehumidifiers or improve room ventilation.
  • Keep the walls clean: Prevent dust or dirt from accumulating on the walls. If you used washable paint, you can easily wipe off any stains with a damp cloth.
  • Inspect the walls regularly: Every so often, check your walls to make sure there are no new cracks or signs of damp. The earlier you spot a problem, the easier it will be to fix.
