Poor Gloss Retention
A deterioration of the paint film may result in excessive or rapid loss of lustre of the topcoat.
- Using an interior paint outdoors.
- Using a lower-quality paint.
- Using a gloss, solvent-based paint in areas of direct sunlight.
While all types of paint will lose some degree of lustre over time, lower-quality paints generally lose their gloss much earlier than better grades of paint. The binder in top-quality acrylic water-based paints is especially resistant to UV-radiation, while solvent-based paints actually absorb the radiation, causing the binders to break down.
When preparing the surface of a coating displaying poor gloss retention, follow the techniques outlined under Chalking.
