Advantages: Decorative painting can create a mood and ambience, custom matching existing design themes and colors. Finishes may be applied to almost any surface without preparation. They last longer than wallpaper and will not peel off under adverse conditions such as high humidity. Faux finishes will not harbor bacteria, mould and insects beneath the surface. They are durable and can be sealed for areas which require scrubbing. They can hide surface imperfections.
