Resene Umbrella Additive
Resene Umbrella Additive is an additive for exterior waterborne coatings providing rapid protection from showers and light rain even before the coating has dried. Once applied, a coating containing Resene Umbrella Additive quickly starts to build a protective shell that then extends throughout the whole coating. Water is able to evaporate from the coating allowing it to dry but showers and light rain simply roll off leaving the still-drying coating firmly attached to the substrate. The Umbrella Effect will work in light showers only. Exterior painting should not be undertaken when medium or heavy rain is expected during the paint’s drying phase.
