Water Streak Mark

Definition:
Water streak markes are blotches that appear to be shinier than the rest of the painted surface on a layer of emulsion (water-based) paint. Usually these occur after the painted surface is hit by light rain.

 

Causes:
• Application of paint during the wet season making it harder to completely dry, because the newly painted surface is hit by rain.
• Exposure to fog, dew, or other sources of dampness on a newly painted surface.

 

Solutions:
• Make sure that the painted surface is completely dry before it is exposed to water.
• Avoid any painting when rain is imminent, in the late afternoon, or during cold and wet weather conditions.
• If blotches appear a few days after painting, these can be removed by hosing them off.
