Excessive paint flow resulting in running or dripping flaws.

The downward flow of a coating film as a result of the film being applied too heavily or fluid-like.

The downward flow of a coating film as a result of the film being applied too heavy or too fluid a wet coat.

paint running down immediately after application. Usually caused by: inadequate surface preparation; overthinned paint; applying paint too thickly; spraying with gun too close to surface; painting when too cold or humidity is too high.

Excessive flow on a vertical surface resulting in drips and other imperfections on the painted surface. Occurs not only when the paint is wet, but also during baking in certain types of paints.

The tendency of a wet paint film to flow downward and become thicker on vertical surfaces.

describes a state of a ship when she is bending downward in the middle and induces compression of the upper deck and tension of the bottom opposite of hogging

Sagging occurs when the paint film "droops" immediately after it is applied. The effect is an uneven finish. Sagging can result from applying too much paint at once, or applying low quality paint that is too thin. Sagging may also be referred to as curtaining.

The downward movement of a paint film on a vertical surface, between the time of application and drying, resulting in an uneven coating having a thick lower edge.

The result of applying a coating too heavily to a vertical surface (wall or wall base) which causes the coating to run down the surface.

Straining of the ship that tends to make the middle portion lower than the bow and stern. (See hogging.)

Sagging is the stress a ship's hull or keel is placed under when a wave is the same length as the ship and the ship is in the trough of two waves. This causes the middle of the ship to bend down slightly, and depending of the level of bend, may cause the hull to snap or crack. This may have been what sank the Prestige off Spain on 19 November 2002.
