Paint Problem: Yellowing | JC Licht

The Problem:The development of a yellow cast in aging paint and clear polyurethanes and varnishes. Most noticeable in the dried films of white or off-white colored paints.

Causes:Yellowing is the result of normal oxidation in oil-based paints and varnishes. Exposing alkyd or oil-based paints to household cleaners (containing ammonia) while the topcoat is still in the curing stage. Exposing paint to high heat sources e.g. stoves, radiators and heating ducts. The yellowing process in oil-based products is accelerated by a lack of light, e.g. dark closets, and areas blocked by picture frames and appliances.

How-to-fix:Use high-quality interior latex paints which tend not to yellow, and water-based varnishes. Keep in mind that oil-based paints will yellow over time. Particularly when exposed to ammoniated cleaning products and shielded from sunlight.
