Epoxy Floor Yellowing or Discoloring — Causes, Fixes & Cost in KL
New epoxy floor has turned yellow, especially in areas exposed to sunlight.
Estimated professional fix: RM280–RM1,800+ depending on area
Yellowing on a new epoxy floor is almost always UV exposure hitting a topcoat that was not UV-stable — common with aromatic resins used indoors then exposed to sunlight. It does not mean the floor is failing, but it will keep getting worse until the surface is re-coated with a UV-stable finish.
