If you have mildew problems on the exterior of a white house here are some tips for preventing mildew.

1. Make sure to clean the exterior of your house with bleach or Zinsser Jomax which can be ran through a pressure washer with the largest tip on the end of the gun. Pressure wash the house with a smaller tip after treating with the chemical of your choice, let the house dry for at least 48 hrs.

2. Repaint the entire house with two coats Zinsser Perma-White paint. Perma-White is a self priming paint so don’t worry about priming any surfaces of the home that are exposed.
