Paint Bubbling & Blistering

Paint bubbles and blistering appear on a white wall.

Paint bubbles can form long after the paint on your walls and ceiling has dried. Take steps to avoid this problem before it occurs.

Paint blisters or bubbles occur when the paint film lifts from the underlying surface. The loss of adhesion between the paint film and surface is usually caused by heat, moisture or a combination of both. This condition eventually leads to peeling. It can be corrected, but the underlying cause of the problem must be addressed or it will recur.



Why Does Paint Bubble or Blister?

  • Painting a damp, dirty, or hot surface
  • Applying oil-based or alkyd paint over latex paint
  • Improper surface preparation
  • Excessive moisture
  • Exposing latex paint to moisture shortly after paint has dried


How to Prevent Paint from Bubbling

  • Make sure the surface is clean and dry
  • Apply primer-sealer over any stains and let it dry completely
  • Prime new joint compound with latex primer
  • Avoid painting in hot or humid conditions
  • Let paint dry completely before exposing the surface to moisture
  • Consider installing vents or exhaust fans in humid areas


How to Fix Paint Bubbles

  • If the blisters do not go all the way down to the substrate, remove them by scraping and sanding. Once the problem area has a smooth finish, coat with primer before applying a quality acrylic latex interior paint.
  • If the blisters go down to the substrate, you will need to remove the source of moisture, if possible.
  • Repair loose caulking and consider installing vents or exhaust fans to lower the humidity in the house.
