Peeling paint on the inside or outside of a building is one of the challenges that property owners sometimes face. Peeling paint not only detracts from a building’s appearance. If it occurs in the inside of the structure, it might potentially represent a health danger to the residents (walls and ceiling). Peeling paint is often caused by a lack of adhesion between the paint and the surface on which it is applied. The following are some of the most typical reasons of peeling paint:

Prolonged exposure to water- this may be caused by water entering through the paint coatings as a consequence of a leak in the roof, gutters, or soffits.
Exposure to a high humidity/excessive condensation environment- this may happen when there is insufficient ventilation and moisture starts to build up on the walls and ceilings.
Incompatibility of the paint with the surface
Inadequate surface preparation (unclean surface) prior to painting
High heat and direct sunshine
Paint job of low quality (wrong paint, wrong primer, poor application methods, lack of expertise and proper equipment)
ancient and aged paint (expired paint)
Corrosive materials that include strong acids or bases
A desert-like setting

How to Deal with Peeling Paint?

Determine and correct the underlying reason – identifying and correcting the underlying cause is an excellent approach to guarantee that you do not have to deal with peeling paint in the future. Examine your structure completely to check that there are no leaks in your roof, gutters, pipes, or soffits. You should only begin repairs when you have determined that the underlying problem has been rectified.

If the quality of the material behind the paint on uPVC doors and windows is satisfactory, it is preferable to just have the windows and doors resprayed rather than incur the expense of having them completely replaced.

Purge/remove all loose paint — Once the underlying source of the peeling paint has been found and removed, the following step is to gently scrape and remove all of the peeling paint off the walls and ceiling. Wear goggles and a face mask to protect yourself from microscopic paint particles getting into your eyes or lungs. Install a floor covering to protect your flooring and collect any debris that falls.
Apply a good-quality filler to the surface to fill up all the gaps and holes created by scraping off the peeling paint. Allow the filler to dry well before proceeding to use a fine-grit sandpaper to remove any irregularity/roughness and make the region level with the surrounding surface. When applying the filler, make sure to follow the manufacturer’s directions exactly. You may also wash the wall and allow it to dry fully before applying primer and a fresh layer of paint. This will prevent peeling from occurring in the future.

Another option is to apply a pre-painting cleaning solution to prepare the surface. These treatments will increase the adherence of the surface to the paint as well as the recoating of a previously painted surface.

Although some paints now have built-in primers, it is still suggested that you go the additional mile and use an oil-based primer with stain-blocking characteristics. This will keep humidity, watermarks, and mildew at bay.

Repaint- Once the primer has dried completely, you may begin repainting the surface. You may apply it with a sponge brush or a roller (a roller is preferred for larger areas). Allow for ample ventilation and paint drying.

Hire a Professional to Do It for You
Handling peeling paint demands accuracy and care to avoid making your walls appear worse than they were before. Hiring professional uPVC Spray Painters with the necessary expertise would be a better alternative.

Conclusion: Peeling paint is a major issue that will only worsen if appropriate solutions are not implemented. So, if you have peeling paint in some sections of your house, it is critical to first identify and address the underlying reasons before proceeding to repair and repaint.
