YELLOWING

Development of a yellow cast in aging paint; most noticeable in the dried films of white paints or clear varnishes.

POSSIBLE CAUSES:

• 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, etc.).

SOLUTION:

• Top quality latex paints do not tend to yellow, nor does non-yellowing varnish.
• Alkyd paints, because of their curing mechanism, do tend to yellow, particularly in areas that are protected from sunlight.
