Did your recently applied clear coat turn hazy white?
During the cooler shoulder seasons of spring and early fall, and even throughout the summer, we occasionally get concern. Water-based finishes can be sensitive to cool, wet weather. If dew or rain get onto a finish before it has fully dried or cured, there can be a startling effect called blushing. Blushing is a white appearance in the finish that happens when water reacts with an uncured finish. It will disappear and turn clear again when the finish dries and cures, but that could take a few warm, dry days. In some extreme situations it has taken several weeks for the blushing to clear up, or if it’s in the late fall it might take all winter when things warm up to cure in the spring.
Although clearing of the whiteness can be sped up through the use of a hair-dryer, it’s generally better to do nothing and let it cure out on its own. Blushing typically doesn’t affect the performance on the finish, but is merely a temporary cosmetic headache. Once the finish has cured and cleared, the blushing should not return.
