General Problems - After painting

Possible Causes

• Over thinned paint applied on the surface
• Highly porous and absorbent surface making film under bound.
• Paint film deteriorating due to action of sunlight , oxygen or salt in air in marine areas

Possible Causes

• Too thin application
• Improper undercoat application
• Incorrect primer usage

Possible Causes

• Substrate not dry -moisture beneath the paint film.
• Painting over rust results in little or no adhesion
• Painting on an inadequately prepared surface.

Possible Causes

• Broken or defective plumbing or some other general building defect.
• Paint should not be applied until the source of dampness is addressed.

Possible Causes

• Moisture beneath the paint film can cause crystallisation of salt from building material such as bricks.
• Paint should not be applied until the efflorescence has ceased to appear and has been removed.

Possible Causes

• Algal/Fungal growths are most likely to occur in damp conditions or on surfaces with a high moisture content.
• Algae growth on exterior masonry can be a problem in sheltered environments that are in close proximity to trees and bushes.

Possible Causes

• Too thick application - paint not thinned as per recommendation.
• Application done on very rough surface or highly absorbing surface
• Poor brush condition
• Poor painter skill

Possible Causes

• Use of interior paint for exterior applications
