Have you noticed small droplets appearing on your fresh coat of acrylic paint? Don't panic – it’s a normal part of the curing process called surfactant leaching.
Sometimes when acrylic paints are drying small, light coloured droplets will appear on the surface. This usually happens if newly painted surfaces are exposed to moisture, either by dew, high humidity or other types of moisture such as steam.
These droplets cause no downgrading of the paint film's durability, they only affect the appearance. Once the paint is dry, wash the surface with Selleys® Original Sugar Soap, and then rinse with plenty of water. Sometimes droplets may continue to appear for some time and will need wiping down until they stop. These droplets are simply surfactants, which are drawn to the surface by moisture.
Yellowing describes the development of a yellow cast in ageing paint solvent-based enamels.
Wrinkling is a term to describe a rough, crinkled paint surface, which occurs when uncured paint forms a 'skin'.
Sagging is the downward "drooping" movement of the paint film immediately after application that results in an uneven coating.
