GLOSSARY TERM
Yellowing
The discolouration of paint over time, often due to exposure to UV light or certain environmental conditions.
INFO
What it is
Yellowing is a discolouration where a finish, particularly a white or pale one, develops a yellow tinge over time. It is a gradual change in the cured film.
Why it matters
Yellowing is most obvious on whites and light colours, where it makes a finish look aged and dirty. Choosing the right product for the setting avoids this and keeps colours looking true.
Where it is used on a project
A risk with some solvent-based finishes and in areas with little natural light. Non-yellowing products are specified where it matters most.
How NECC approaches it
For whites and pale colours, and in at-risk areas, we specify non-yellowing, colour-stable coatings so the finish keeps its intended shade over time.
