This will happen with any water-borne acrylic, including the Acriglaze Matte Finish, under one of the following conditions: it is either too humid where you are applying the finish, or it has been applied too thickly. What happens is that the top layer of the finish dries quickly, trapping moisture underneath, resulting in a whitish, cloudy or milky appearance. Sometimes this will clear over time, even a matter of several days, but if it doesn’t, your only option is to sand through the finish and reapply – under drier conditions and in a thinner coat. Two thin coats are more desirable than one thick coat.
