Causes

Causes

All the sections covered with a joint compound stay white, while the rest turns yellow.

  • Apartment improperly heated.

  • Joints poorly dried.

  • Lack of ventilation.

Fresh water-based paints when applied before a floor varnish will quickly turn yellow following the application of urethane-based varnishes which harden when expose to humidity. Their strong smell makes them easily recognizable.
