PROBLEM: FROSTING

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

FROSTING CAUSES
Usually forms in protected areas not receiving cleaning rains. Dark colors over paint or primer using excessive extender pigments. Mistaken for efflorescence.

FROSTING 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.

PRIMERS & INTERIOR FINISHES
Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
