Description

Salty looking discoloration, most visible on darker colors, sometimes mistaken for efflorescence.

 

 

 

 

Probable Cause

• 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 result, use a power washer.

• Frosting often will bleed through new paint if an alkyd-based primer isn’t used.

 

Primers & Interior Finishes

• An alkyd primer is essential to avoid a reoccurrence of bleeding through the new finish coast only.

• Select a top quality California Paints exterior paint in the color and sheen of your choice.
