10 common problems in exterior painting and how to fix them

  1. Peeling or Flaking: This occurs when the paint doesn’t properly adhere to the surface. To fix it, remove the loose paint and sand the surface. Apply a primer and then repaint.
  2. Cracking or Alligatoring: This is when the paint cracks and looks like alligator skin. It happens when the top coat dries too quickly or is too thick. To fix it, remove the loose paint, sand the surface, and apply a primer before repainting.
  3. Fading: This is when the paint loses its color due to exposure to sunlight. To fix it, apply a fresh coat of paint with a higher quality pigment and UV-resistant formula.
  4. Chalking: This occurs when the paint breaks down and produces a chalky residue. To fix it, wash the surface with soap and water, then apply a primer and repaint.
  5. Blistering: This is when the paint bubbles up and forms blisters. It occurs due to moisture buildup under the paint. To fix it, scrape away the blistered paint, sand the surface, apply a primer, and repaint.
  6. Mildew or Mold: This is when the paint grows a fuzzy, discolored substance due to high humidity or moisture. To fix it, wash the surface with a bleach and water solution, let it dry, then apply a mildew-resistant paint.
  7. Stains: This is when the paint has discolored stains from substances like water or rust. To fix it, clean the surface with a stain-removing solution, rinse, and repaint.
  8. Wrinkling: This is when the paint forms wrinkles or creases. It occurs when the paint is applied too thickly or if it’s exposed to high humidity. To fix it, sand the surface, apply a primer, and repaint.
  9. Sagging: This occurs when the paint drips and sags due to overapplication or improper drying. To fix it, scrape away the sagged paint, sand the surface, and repaint.
  10. Uneven Gloss or Sheen: This is when the paint has uneven shine or luster. It occurs when the paint is not applied uniformly or when different sheens are used. To fix it, apply a coat of paint with the same sheen, and make sure to apply it uniformly.
