Paint running down immediately after application, leaving an uneven coating appearance.
SAGGING PROBABLE CAUSES
Application technique and inadequate surface preparation. Over-thinned paint. Applying the paint too thickly. Spraying with the gun too close to the surface. Painting when the temperature is too cold or the humidity too high.
Before the paint dries, immediately brush or roll out running paint evenly. Properly prepare the surface, sand glossy areas. Do not thin the paint. Apply uniformly at the paint's recommended rate. Two proper coats are better than one thick coat.
PRIMERS & INTERIOR FINISHES
Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
