Paint cracking on wall – Causes, Prevention and Solutions

Paint cracking on wall and ceiling can be a frustrating issue for any homeowners or property managers. Not only does it look unsightly, but it can also indicate underlying problems that may require professional attention. In this post, we will explore the causes of paint cracking, how to prevent it, and the best solutions for dealing with it.

Causes of Paint Cracking

Paint cracking is a common issue that can be caused by several factors. Here are some of the most common reasons why paint may crack on your walls and ceilings:

  1. Poor Surface Preparation

Before applying paint, it is essential to prepare the surface properly. This includes removing any dirt, debris, or old paint that may be present. If the surface is not adequately prepared, the paint may not adhere correctly, causing it to crack or peel.

  1. Moisture

Moisture can cause significant damage to painted surfaces, especially in areas that are prone to high humidity or water exposure. When moisture penetrates the surface, it can cause the paint to expand and contract, leading to cracking and peeling.

  1. Temperature Changes

Temperature changes can also cause paint cracking, especially in areas with extreme weather conditions. When the temperature fluctuates, the paint may expand and contract, causing it to crack or peel.

  1. Age of the Paint

Over time, paint can deteriorate, leading to cracking and peeling. This is especially true if the paint was not of good quality or if it was applied improperly.

Prevention of Paint Cracking

Preventing paint cracking requires proper surface preparation and the use of high-quality paint products. Here are some tips on how to prevent paint cracking on your walls:

  1. Clean the Surface

Before painting, ensure that the surface is clean, dry, and free of debris. Use a scraper or sandpaper to remove any loose paint, and clean the surface with a damp cloth to remove dirt and dust.

  1. Prime the Surface

Priming the surface before painting can help to improve paint adhesion and prevent cracking. Choose a primer that is appropriate for the surface and paint type, and apply it according to the manufacturer’s instructions.

  1. Use High-Quality Paint

Investing in high-quality paint products can help to prevent paint cracking and ensure a long-lasting finish. Look for paint that is specifically designed for the surface and environment where it will be applied.

Solutions for Paint Cracking

If your walls are already showing signs of paint cracking, there are several solutions that you can try. Here are some of the best ways to deal with paint cracking:

  1. Scrape and Sand

If the cracking is minimal, you can try scraping and sanding the affected area. Use a scraper to remove any loose paint, and then sand the surface until it is smooth. Wipe away any dust with a damp cloth before repainting.

  1. Apply a Sealant

If the cracking is more severe, you may need to apply a sealant before repainting. A sealant can help to prevent moisture from penetrating the surface, reducing the risk of further cracking.

  1. Repaint

In some cases, the best solution is to repaint the entire surface. Choose a high-quality paint that is appropriate for the surface and environment, and apply it according to the manufacturer’s instructions.

To sum up

Paint cracking on walls can be a frustrating and unsightly issue. However, by understanding the causes and taking the appropriate preventative measures, you can avoid this problem. If your walls are already showing signs of cracking, there are several solutions that you can try, including scraping and sanding, applying a sealant, or repainting the entire surface. By taking these steps, you can ensure a beautiful, long-lasting finish that will enhance the appearance of your home or property for years to come.


  • Can I fix paint cracking on my own?
    Answer: Depending on the severity of the cracking, you may be able to fix it on your own with proper surface preparation and the use of high-quality paint. However, if the issue is severe or widespread, it is recommended to hire a professional.
  • Will paint cracking on walls continue to worsen over time?
    Answer: Yes, if the underlying causes of paint cracking are not addressed, the problem will likely continue to worsen over time.
  • Can I just cover up paint cracking with more paint?
    Answer: While it may be tempting to cover up paint cracking with more paint, this is not a recommended solution. The underlying issues causing the cracking will still be present, and the new paint may not adhere properly, resulting in more cracking and peeling.
  • How often should I repaint my walls to prevent paint cracking?
    Answer: The frequency of repainting your walls will depend on several factors, including the quality of the paint used, environmental factors, and the amount of wear and tear the walls receive. It is generally recommended to repaint every 5-10 years to ensure a fresh, clean look and prevent paint cracking.
