Porous materials equivalent to unfinished wood might soak up more paint. Without primer, these surfaces can require several coats earlier than the color looks consistent. Plastic, shiny metal, and previously painted surfaces may additionally want additional preparation to make sure proper adhesion.

Large objects can typically require an extra coat because it is more tough to keep up the same spray distance and coverage across your complete surface.

How Long Ought to You Wait Between Coats?
