Frosting or Salty Paint

Frosting or Salty Paint
Definition: Salty looking discoloration, most visible on darker colors, sometimes mistaken for efflorescence

Causes:
- Usually forms in protected areas not receiving cleaning rains
- Dark colors over paint or primer using excessive extender pigments
- Mistaken for efflorescence

Solutions:
- Remove frosting with a wire brush on masonry and sanding on wood
- Rinse thoroughly with a garden hose
- For best and quickest results use a power washer
- Frosting often will bleed through new paint if an alkyd -based primer isn't used (an alkyd primer is essential to avoid reoccurence of bleeding through the new finish coat only)
