Tip of the Month

PICTURE FRAMING

An effect of non uniform color that can appear when a wall is painted with a roller, but is brushed at the corners. The brushed areas generally appear darker, resembling the “frame” of a “picture”. Also, sprayed areas may be darker than neighboring sections that are brushed or rolled. Picture framing can also refer to sheen effects.

POSSIBLE CAUSES:

• Usually a hiding (coverage) effect. Brushing will generally result in lower spread rates than rolling, producing a thicker film and more hiding.
• Adding colorant to a non-tintable paint, or using the wrong type of level of colorant, resulting in variation in color, depending on the method of application.

SOLUTION:

Make sure that spread rates with brushes and rollers are similar. Don’t cut in the entire room before roller coating. Work in smaller sections of the room to maintain a “wet edge”. Factory colors, as well as in-store tints, should be thoroughly shaken at the time of sale.
