Why Do Some Floors Turn Yellow?

Sometimes it’s as simple as a reaction of two ingredients coming together (i.e., a vinyl or rubber backed floor mat in contact with the floor)

Discoloration, or Yellowing of Floor Finishes Generally Occurs When Certain Ingredients Darken Upon Exposure to Heat and Light

These ingredients include highly styrenated acrylic polymers, certain varieties of polyethylene wax, and aromatic (cyclic) polyurethanes.

What to Look For in a High Quality Floor Finish That Resists Yellowing

A high quality floor finish will have low styrene content acrylic polymers, incorporate non-yellowing polyethylene waxes and formulated not to discolor because it uses aliphatic (non-cyclic) polyurethanes.
