Resene Hot Weather Additive is a specially formulated product designed to slow down the drying time of Resene waterborne paints. Adding 2%-5% of this additive to your paint can help improve application issues caused by fast drying in hot weather conditions. In more severe cases, using a higher percentage of Resene Hot Weather Additive can be beneficial, but do not exceed 10% (400ml per 4 litres). Please note that this product should not be used in conjunction with Resene Brushing Additive.
