Foaming

Definition:
Foaming is the formation of bubbles that create small holes in the shape of craters, that happen when air pockets burst in the paint coating, either during application of paint coating or after the paint coating has dried.

 

Causes:
• Paint inside the container was shaken.
• Using low quality paints.
• Applied paint dried too soon.
• Using the wrong type of roller.
• Application of gloss or semi-gloss paint on porous surface.

 

Solutions:
• Sand the affected area and clean off before reapplying paint coating.
• Apply appropriate base paint before applying paint to a porous surface.
• Use Mowilex Interior or Exterior paints.
• Use a paint roller with few cavities.
