Symptoms: Blistering
Blistering paint is identified by small to medium sized bubbles or blisters under the paint film and is most common on wood siding and trim.

Potential Causes:

  • Painting in direct sunlight on a hot substrate (surface being painted) which traps solvent vapor as the paint dries too quickly.
  • Painting when the wood is damp causing trapped moisture to expand the paint film.
  • Dew, rain or very high humidity after latex paint has dried if the latex paint is of lower quality or the substrate surface preparation was inadequate.
  • House moisture escaping through the walls due to improper house ventilation.

Possible Repairs:

  • Scrape away blistered paint and sand to bare wood.
  • Let wood completely dry.
  • Sand, prime and paint in non-direct sunlight and non-humid conditions.
  • Use high quality latex paint.
  • If due to lack of home ventilation, corrective repairs must be made to properly ventilate the home's walls, roof and eaves, bathrooms, etc.
  • Check and repair any loose or missing caulking around windows and doors.
  • Consider providing siding ventilation.
