Picture Framing
|
 |
An effect of non-uniform color appearing when a wall is painted with a roller, but 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 Cause:
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 or level of colorant.
Solution:
Make sure that spread rates with brushes and rollers are similar. Do not cut in the entire room before roller coating. Work in smaller sections of the room to maintain a "wet edge."
With tinted paints, be sure the correct colorant-base combinations are used. Factory colors, as well as in-store tints, should be thoroughly shaken at the time of sale.
