CAUSES: Frequently, several layers of paint with low binder content will build up over the years, especially on older homes. These layers of paint can include calcimine, white wash and other soft finishes. These poorly adhering coatings come off and adhere to the applicator, particularly to roller covers.
SOLUTIONS: Remove as much of the old coating as possible by scraping or using chemical removers. Often this can be done by wetting the finish with hot water and scraping with a 4 inch blade. Sand smooth and apply a coat of oil-based primer-sealer. Repaint with latex-or oil-based ceiling paint.
