What to Do About Sagging or Dripping Paint

When paint sags or forms drips down the wall after painting, it can leave a shabby, uneven mess. This common problem is the result of applying too much paint, using paint that is too thin or painting in spaces that are too humid or too cool.

Try to keep the room in which you're painting at a constant temperature, somewhere between 65 and 85 degrees Fahrenheit with moderate humidity. Painting in conditions outside these parameters can lead to any number of problems with your work.
If you notice any drips, drooping or sagging on any of your coats of paint, fix them immediately while the paint is still wet. Simply brush or roll out the excess paint to work it in with the rest of the coat. If the paint has already dried, just add another coat of paint to cover up the running drips. If you notice any glossy areas, lightly sand them with fine-grit sandpaper before applying the new coat for optimum adhesion.
When painting the walls, always paint from the top down, again to be sure drips are covered.
An unnecessary amount of dripping usually occurs when soaking up the roller with too much paint,
