Blistering
 

Description:
Bubbles resulting from loss of adhesion and lifting of the paint film from the underlying surface.

Possible Cause:
• Applying oil-based paint over a damp or wet surface.

• Moisture seeping into the home through the exterior walls.

• Exposure of latex paint film to high humidity or moisture shortly after paint has dried, especially if there was inadequate surface preparation and/or poor ventilation in areas such as kitchens and bathrooms.

Solution:
• If blisters do not go all the way down to the substrate: Remove blisters by scraping and sanding, and repaint with a quality latex interior paint.

• If blisters go down to the substrate: Remove the source of moisture, if possible. Repair loose caulking; consider installing vents or exhaust fans. Remove blisters as above, remembering to prime before applying the topcoat.

Recommended System:
Primer
1 Coat of FLEX BON #107 Series Interior Acrylic Latex Primer
