Concentration
of water-soluble paint ingredients called “surfactants” on the surface
of a latex paint. May be evident as tan, brown, or clear spot or area
and can sometimes be glossy, oily, or sticky.
POSSIBLE CAUSE
Latex paints contain surfactants designed to make applying them possible. All latex paint
Formulas
will exhibit this tendency to some extent if applied in area where
moisture (rain, dew, high humidity showers, laundry rooms, etc) can
come in contact with an uncured latex paint.
Cool temperatures will retard the paint’s curing process, which can allow surfactants to
Separate out and float to the top of the coating.
Moisture
accumulating on a fresh latex paint will retard the paint’s drying.
This moisture may extract and concentrate different water –soluble
materials from within the paint onto the paint surface when the water
evaporates; a concentrated residue is left behind causing staining,
unsightly runs, and gloss patterns.
SOLUTION
Inside: Wash the affected area with soap and water, and rinse. The discoloration may
Occur once or twice again before the surfactant is completely removed. When the
Paint is applied in a bathroom; it should dry thoroughly before using the bath or shower.
Remove as much staining as possible before repainting.
Outside:
Apply paint to all surfaces during weather conditions that allow proper
curing of the paint film. When surfactant leaching occurs, flush with
clean water immediately, before the stains have sufficient time to set
up or harden. Light scrubbing with a soft brush is acceptable. If
stains cannot be removed in this manner, then repainting will be
necessary during more favorable weather conditions.
In many minor cases, when left to weather, exterior surfactants will wash off with normal weathering.

INTERIOR
Suggested Finishes Reapply the same or an upgr ade coating.
EXTERIOR
Suggested Finishes Reapply the same or an upgrade coating.
