PICTURE FRAMING

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 or level of colorant, resulting in variation in color, depending on 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." 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 time of sale.
