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 and inside closets)
Solution
Top quality water-based paints such as Dulux Aquanamel® do not tend to yellow, nor does non-yellowing varnish.
Solvent-based paints, because of their curing mechanism, do tend to yellow, particularly in areas that are protected from sunlight.
To prevent yellowing, use a premium quality water-based paint in place of solvent-based paint. For more information, please consult our detailed Technical Advice note on the topic.
