Foaming 9 Sagging

SAGGING

SAGGING

The downward ‘drooping’ movement of the paint film immediately after application.

POSSIBLE CAUSES

• Applying too much paint to the surface. • Applying paint that is too thin in viscosity. • Poor conditions during the application or drying period (eg. cold substrate, low air temperatures and/or high humidity).

SOLUTIONS

• If paint is still wet, immediately brush out or re-roll to redistribute the excess paint evenly. • If the paint has dried, sand and reapply a new coat of paint at the recommended coverage rate. • Do not over-thin the paint. • Ensure application and drying conditions conform to manufacturer’s recommendations.
