Probable Cause

  • Warm, humid conditions, poor air circulation and little direct sunlight, like under eaves and overhangs.

  • Shrubbery planted too close to a building is an ideal place for a mildew to grow.

  • Mildew must be removed before painting or it will come through the new paint.

 

Solutions

  • Remove all mildew by scrubbing with a solution of household bleach and water.

  • Mix 1 part bleach and 3 parts water.

  • Wear rubber gloves and eye protection.

  • Power washing is recommended for larger areas.

  • Rinse thoroughly with a garden hose.

 

Primers & Interior Finishes
