Linoleum is affordable, tough and comes in lots of color and texture choices. There are plenty of reasons why clients choose linoleum, and one of them is its ability to resist stains. However, no flooring material is completely immune to discoloration, and there are occasions when linoleum may acquire a yellowish cast. This discoloration is known as ambering.
Ambering happens when the linseed oil that is a component of linoleum oxidizes with age and exposure to UV light. The combination causes a chemical reaction and that gives it a yellowish cast. It is not a stain and cannot be scrubbed away or treated so that the linoleum goes back to its original look. This means that the only solution to get rid of ambering in linoleum is to replace it.
When flooring contractors are talking about the pros and cons of linoleum to their clients, it’s always a good idea to mention what can possibly happen when flooring is exposed to UV rays for too long.
