Common Paint Problems & Solutions
Blistering:
Bubbles resulting from localized loss of adhesion and lifting of the paint
film from the underlying surface.
Possible Cause:
- Painting a warm
surface in direct sunlight
- Application of
an oil-based or alkyd paint over a damp or wet surface
- Moisture escaping
through the exterior wall (less likely with latex paint than with oil-based
or alkyd paint)
- Exposure or latex
paint film to dew, high humidity or rain shortly after paint has dried,
especially if their was inadequate surface preperation
Solution:
- If blisters go
down to the substrate, try to remove the source of moisture. Repair
loose caulking; consider installing an exhaust fan. Remove blisters
- If blisters do
not go all the way down to the substrate, remove them by scraping, then
sanding; prime any bare wood and repaint with a quality exterior paint.
