A hardwood or resilient floor with Hygienius integrated in its lacquer layer enables a natural photocatalytic process to take place when exposed to daylight or indoor light. This allows harmful emissions and unpleasant odors to be broken down as well as degradation of bacteria, fungi and even virus on the surface. This technology by Välinge also makes it easier to remove dirt, minimize unattractive moisture streaks and allows the flooring to dry more quickly.
