Burnishing: Spots of increased sheen where paint is rubbed. Even a fingernail stroke can burnish.
Burnishing probable causes: Selection of a flat finish for areas subject to heavy wear and soiling. Repeated spot washing using abrasive cleansing powders rather than liquid detergents. Furniture or other objects rubbing against walls or other painted surfaces. Dark colors show more.
Burnishing solutions: Paint high traffic areas with high quality, washable semi-gloss or gloss finishes. Do not clean with abrasive cleansers. Wash with nonabrasive detergents with a sponge or soft cloth and rinse with clean water. Gloss finishes are easier to clean and resist soil.
Primers & interior finishes: Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
