Yellowing

Development of a yellow cast in aging paint: most noticeable
in the dried films of white paints or clear varnishes.
Possible Cause:
-
Oxidation of alkyd or oil-based paint or varnish.
-
Heat from stoves, radiators and heating ducts.
-
Lack of light (e.g., behind pictures or appliances, inside
closets).
Solution:
Top quality latex paints and non-yellowing varnish do not
tend to yellow. Due to their curing mechanism, many alkyd
paints, do tend to yellow, particularly in areas that are
protected from sunlight.
