Marring/ Burnishing 10 Surfactant Leaching

SURFACTANT LEACHING

SURFACTANT LEACHING

Soapy, sticky, glossy spots or streaks on newly painted surfaces, usually within the first few weeks after application.

POSSIBLE CAUSES

• Poor conditions during the application or drying period (eg. low air temperatures, high humidity, condensation, rain or dew). • Adding tinter above recommended tinting levels.

SOLUTIONS

• On exterior surfaces, surfactant leaching will usually disappear over a short period without the need for intervention. Rinsing with fresh water can help to wash it away. • On interior surfaces, surfactant leaching can be easily removed (allow the paint film to fully cure and harden) by washing with a mild soapy solution and a soft cloth or sponge, followed by a thorough rinse with clean water. • Ensure application and drying conditions conform to manufacturer’s recommendations.
