Yellowing

YellowingDevelopment of a yellow cast in aging paint; most noticeable in the dried film 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.
