Primer isn't always required, but it's almost always a good idea. It seals surfaces, improves adhesion, and ensures your paint looks smooth and even.

When should you skip primer?

To be fair, there are situations where skipping primer is a reasonable call. If you're painting a similar color over a previously painted surface that's clean, sound, and in good condition — no stains, no peeling, no glossy sheen — a self-priming paint or even straight paint may be fine.
