Definition: A non-uniform color effect that can appear when the corners are first cut in with a brush, and then the walls are rolled. The brushed areas generally appear darker, resembling the “frame” of a picture. Also, sprayed areas may be darker than adjacent sections that are brushed or rolled. Also known as Picture Framing.
Non-Uniform Color Causes:
* Usually a coverage effect (brushing will generally result in a thicker film than rolling)
* Adding colorant to a non-tintable paint or using the wrong type or level of colorant
Non-Uniform Color Solutions:
* Make sure that the paint is applied evenly when brushing and rolling.
* With tinted paints, be sure that the correct paint base-colorant combinations are used.
