Paint Yellowing
Yellowing is the development of a yellow cast in aging solvent-based enamels. It’s most noticeable in the dried films of white paints or clear varnishes.
Possible Cause
Yellowing can be caused by the oxidation of alkyd or oil-based paint or varnish, heat from household items like stoves and heaters, or a lack of light to the area. It is also caused by exposure to ammonia from adjacent acrylic paint application in the same room; ammonia can oxidize the alkyd component in the oil based enamel and cause premature yellowing.
Solution
Where possible, choose a top quality water-based paint and/or a non-yellowing varnish, we recommend Dulux Aquanamel®. Acrylic paints do not tend to yellow as much as solvent-based paints, and are the only sure way to protect against premature yellowing.
