When to Prime Before You Paint
By: Danny Lipford
Is it always necessary to prime before you paint over a previous paint job? -Cedric
Unless the surface is unfinished or you’re switching between types of paint—such as oil based woodwork being covered by latex paint—you don’t have to prime before painting again.
- If the surface is dirty or greasy, clean it thoroughly before painting.
- If it is glossy, it’s a good idea to dull it first with sandpaper or a liquid deglosser.
