Most interior paint problems and painting mistakes are correctable. Below you’ll find solutions for the most common wall paint problems. (Note: Photos courtesy of The Paint Quality Institute)
Bubbles, which look like blisters, sometimes form on the paint film, resulting from the localized loss of adhesion and lifting of the paint film from the underlying surface.
Poor paint flow and leveling occur when the paint application does not flow smoothly and the paint fails to dry into a smooth film, leaving unsightly brush and roller marks.
Blocking occurs when two painted surfaces stick when pressed together (e.g., a door sticking to the jamb).
Poor paint hiding is the inability of the dried paint to obscure, or "hide," stains or previous colors on the underlying surface.
Burnishing occurs when the gloss, or sheen, of paint film increases when subjected to rubbing or brushing.
Poor print resistance is the tendency of paint film to take on the imprint of an object that is placed on it (for example, dishes and other objects).
Caulk may lose its initial adhesion and flexibility, which will cause it to crack or pull away from surfaces.
Poor scrub resistance is indicated by the wearing away or removal of the paint film when scrubbed with a brush, sponge, or cloth.
Dry paint sometimes cracks or flakes through at least one coat due to aging, which ultimately will lead to complete failure of the paint.
Poor sheen uniformity, or "flashing," leads to shiny or dull spots on a painted surface.
Foaming and cratering occur when bubbles ("foaming") form during paint application. When the bubbles break during application and drying, they result in small concave depressions ("cratering").
Paints with low stain resistance fail to resist the absorption of dirt and stains.
Roller marks and "stipple" are unintentional textured patterns left on the paint film by the paint roller.
Lap marks cause the appearance of a denser color, or increased gloss, where wet and dry layers of paint overlap during application.
Paint roller spattering occurs when the paint roller throws off droplets of paint during application.
Mildew can appear on the surface of paint or caulk as black, gray, or brown spots or areas.
Sagging is a downward "drooping" movement of the paint film that occurs immediately after application, resulting in an uneven coating.
Mud cracking results in deep, irregular cracks in the paint that resemble dried mud on the dry paint film.
Surfactant leaching appears as tan or brown spots or areas on the painted surface; they can be glossy, soapy, or sticky.
Picture framing occurs when corners or edges appear darker than the rest of the wall.
When uncured paint forms a skin, it can wrinkle, making the surface appear rough and crinkled.
