Paint Problems - Mildew

On the Outer Banks, mildew is simply a fact of life. Heavily wooded areas (such as Southern Shores or Kitty Hawk) block the sunlight and the frequently damp air creates a perfect environment for mildew.

Mildew is actually fungal growth (usually black or gray). Walls with northern exposure and the underside of eaves are particularly prone to mildew.

Other causes of mildew include the use of low quality paint, failure to prime bare wood before painting, painting over a substrate on which mildew has not been removed, and applying paint in a very thin coat.

At Beach Painting, we use the highest quality paints available (all of which are mildew resistant). We spot prime bare wood before painting. We always chemically treat and wash substrates before applying paint and we apply the paint to achieve the highest possible dry film thickness.

If you encounter mildew, you can test by applying a few drops of household bleach to the area and then rinsing. If the discoloration disappears, it is probably mildew. It can be removed by taking a scrub brush and a diluted bleach solution (three parts water, one part bleach) to the area. Always wear rubber gloves and eye protection when doing this. Rinse the area thoroughly and apply primer to any bare wood before touching up with a high quality exterior paint.

The best overall solution is to incorporate the power washing of your home's exterior into your annual Fall or Spring maintenance. Call us today for a free estimate!
