DYI, what is mildew, what you can do to kill mildew

WHAT IS MILDEW?

 

This naturally occurring fungi finds the damp shady areas of the house, under eaves and gutters, along the bottom edges of clapboards and shaded gables. It appears as black, gray or greenish dirt spreading out from its concentration in the crevices and horizontal corners of the house.

 

 

WHAT TO DO:

 

Mildew is easily removed with a solution of household chlorine bleach and water. Mix about a cup of bleach to a gallon of water. A stronger solution may be needed for stubborn areas. A garden sprayer works great to apply the solution. Spray the solution from the bottom up to avoid streaking. Scrubbing should not be required, the mildew should just disappear back into Nature. After the mildew is gone rinse the area with a water hose. 

WHAT WILL PREVENT IT?

There is not much one can do to prevent mildew, but there are some measures that you can take to retard and delay mildew's reoccurrence.

Do not use oil (Alkyd) based paints or stains on the exterior of your house. The oil base is food for mildew. Acrylic exterior paint or stain is a better choice.

Have additional mildew retardant added to the paint before application. Most exterior paints have a fungicide ingredient, however, you can request that additional fungicide be added at the paint store  *M6) for an additional fee of course).
