You probably don't need a primer. If the current wall is smooth, clean and covered with the same type of paint (both are oil-based for example), you can head straight for the paint. You need to fill holes, spackle and sand*, maybe even cut a new piece of drywall in to the existing wall.
Absolutely not. Unless your walls are bare drywall and have never been painted. You see, the primer's main job is to provide adhesion. So if your walls are already painted, they just need to be clean, dry, and dull. And then any additional topcoat you're putting on will adhere.
Short answer, yes, if you want the best finish, we always recommend priming, especially if you're painting over a darker color than what you're going to paint on, or if there are any surface imperfections.
Primer is formulated to bond better then paint to surfaces. Therefore, if you don't use primer, you will often find that it takes more coats of paint to fully cover the wall then when using a base coat of primer. Also, the paint may not last as long since is doesn't bond as well to the surface.
One negative effect of using expired paint is that it may not adhere well to surfaces or may peel off easily. The color may also be inconsistent, and the paint may not dry properly. Additionally, expired paint may emit a foul odor, which can be unpleasant and potentially harmful.
If you're painting your house on your own, you need to remove old paint before painting the walls or hire professionals for this important step. Removing old, peeling paint helps the new paint adhere better, resulting in a smoother look that stays beautiful longer.
You can tell paint has gone bad by the smell and texture. A rancid or sour-smelling paint means your paint has gone bad. In particular, the smell of bad paint is similar to sour milk. Other indicators of expired paint include a lumpy or chunky paint consistency.
In order to save time and money, professional painters recommend using a good primer.
While primer is an important step, it's not always necessary. You don't need to use a primer if your paint project has all of these conditions: You're painting drywall surfaces that are smooth, clean, and don't need repair. Surfaces were previously painted with latex in a flat or eggshell finish.
Without using a primer, dark colors can bleed through the new paint layers, which might necessitate applying additional coats and consequently increase the time and materials needed.
Paint and primer combination products do work in certain situations, but every paint job is different. Paint and primer have two different, distinct functions and many times work best as two separate products. Paint provides color, hiding, sheen, scrub resistance and protection against the elements.
You will want to use 2-3 coats of primer to ensure there is a good bond between the new paint and the wall, and also to cover up any previous colors, especially if they are red, orange, or a strange outdated color. In short, you will typically need 2 coats of primer for most painting projects.
In general, the only time a primer is not needed is if you're re-painting a surface that's in good condition. Your neighborhood Sherwin-Williams paint expert can provide additional advice about selecting and applying the right primer for your project.
How Do I Paint Over Painted Walls? If the wall is in good condition and the paints are chemically the same (both latex, for instance), you have a few options when the new paint is the opposite shade of the old paint. You can use a primer to thoroughly cover the old color, then apply 1 or 2 coats of the new paint.
If you're painting a humid area like a bathroom, which is more susceptible to mildew and leaching. If your wall has stains that you want to block (like water spots from a bathroom leak or smoke damage from a fire in a kitchen). When painting unfinished wood trim or other very porous surfaces.
Above all else, self-priming paint is designed to eliminate the need for primer. It is typically thicker than average paint, with a higher concentration of solids to help cover blemishes, leave a more robust finish and ultimately make the process quicker and easier.

WHAT IS A PRIMER? Primer is often referred to as a base for Foundation or a Foundation primer. They are most commonly used to achieve a controlled matte finish. It isn't necessary to use a Primer before foundation, yet there are many benefits to adding this product into your makeup bag.
Primer is typically an off-white color. Many paints achieve their true color—and in fewer coats—when applied over this kind of primer. The simplest option is to use a paint and primer combination, such as Valspar Reserve.
In most situations, a good rule of thumb is to use a primer plus two coats of paint. If you use this rule, you may do one more coat than needed but this won't hurt the final product. There are few situations where this rule of thumb will result in doing too few coats though which is why it is prevalent advice.
