Is it always necessary to prime before you paint over a previous paint job?

Hi 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.
For more information on priming, see A Homeowner’s Guide to Paint Primer.
