Why Does Paint On Outside Trim Come Off?

Peeling paint on your home’s exterior can be caused by various factors, including moisture issues, poor paint conditions, improper surface preparation, and incompatible paint layers. Moisture from rain and snow, poor attic ventilation, overflowing gutters, or misdirected sprinklers can cause peeling paint. Bad paint conditions, such as applying paint outside the manufacturer’s recommended application temperatures and conditions, not following dry times, poor surface prep, and incompatible paint layers, can also contribute to peeling paint.

To prevent peeling paint, it is crucial to prepare the surface by scraping off loose and peeling paint. Be aggressive with the scraper to remove any flakes of paint. Water is recognized as one of the primary causes of paint flaking, peeling, and chipping.

Peeling paint is primarily caused by moisture and water, particularly in wet areas like bathrooms, laundry, and kitchens. Other issues may include excess humidity or a leaky roof.

Dirty walls are a precursor to peeling paint, and a coat of paint applied over a dirty surface is almost guaranteed to peel or crack. A good primer is also essential for adhesion.

Combining different paint types can also cause peeling paint. For example, latex-based paint covering oil-based paint can cause peeling. It is essential to be aware of the paint used and choose the next layer wisely.
