Should I prime before I paint over painted walls in my kitchen?

It usually is a good idea to prime the walls first,as the new paint will use less of.

If the original paint on your walls aren't a dark or bright color you should be good with no primer.

Buy good quality paint and talk with the store associate. You shouldn't have to use a primer if walls are originally painted light, neutral or pale colors.

Having worked in a paint dept. It is a good idea to prime the walls,or you can opt for choosing not to .

Hi Jrp,

As others have said, you shouldn't have to prime it if the current paint is a light color and not really old. I would say the exception is if your old paint has a glossy finish. If it does, lightly sanding and priming will help the new paint stick better. If you decide not to prime, it wouldn't hurt to buy a paint that has primer in it. You don't state which room you want to paint, but do remember that if there is any grease on the wall left over from hand prints or people leaning their head against the wall, the new paint might not cover well. Here's an article from thespruce.com that can help you decide. Best of luck on your paint job!

Yes you should that way the color that was there before will not be seen after you prime it

If you are unsure - just prime with Kilz to be safe. It makes the paint go on easier and will give you the true color you actually purchased.

If you are covering a darker wall probably...light wall probably not
