Definition: Downward “drooping” movement of the paint film immediately after application, resulting in an uneven coating or painting sagging.
CAUSES:
* Applying too much paint per coat
* Painting under cool, humid conditions
* Over-thinning the paint causes painting sagging
* Applying paint over a glossy surface that doesn’t provide sufficient “tooth” for the paint to bond
* Airless spraying with the gun too close to the surface being painted
PAINTING SAGGING SOLUTIONS:
* If the paint is still wet, immediately brush out or re-roll to even out the paint film.
* If the paint has dried, sand and re-apply a new coat of paint to prevent painting sagging
* Correct any unfavorable conditions: Do not thin the paint, avoid painting under cool or humid conditions, sand glossy surfaces.
