Mildew

Back to exterior problems...
Areas of black, gray, brown spots formed on paint or other surfaces, particularly in damp, shady areas.

Mildew probable causes - 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 mildew to grow. Mildew must be removed before painting or it will come through the new paint.

Mildew solutions - remove all mildew by scrubbing with a solution of household bleach and water. Mix 1 part bleach to 3 parts water. Wear rubber gloves and eye protection. Power washing is recommended for larger areas. Rinse thoroughly with a garden hose.

Primers and exterior finishes - Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Ask your Muralo dealer for the best Muralo exterior paint containing mildewcidal protection, in the color and sheen of your choice.
