Most products that are advertised as paint and primer in one will be more costly. The project will also cost you more if you buy a paint and primer in one, have issues with adhesion or bleed through, then have to buy another primer just to have to repaint.
Paint and primer in one is a thicker paint that builds higher to give you a sturdier coat of paint. Since it is tinted just like conventional paint, there is no need to cover up the initial layer of white primer.
Adhering to surfaces better than regular paints but not as well as primers, 2 in 1 paint and primer products work best on surfaces that have already been painted. When used on raw surfaces, previously applying a high-quality primer can help ensure better coating adhesion.
On new drywall, you will use 3 coats of the finish material instead of a primer coat plus 2 coats of finish. Most projects where you're going over a previously-painted surface do not require the use of a primer.
Applying primer to solve the problem (for example uneven, porous surfaces, strong colors or stains that might bleed through the paint, or adhesion issues that might cause peeling of the paint) before applying paint may prevent the need to re-paint or add several more coats of paint to get desired results.
Covering a dark paint color with a lighter paint color will require multiple coats of new paint. It may make more sense to cover the old color in a primer, which is less expensive than your paint. This way, you will only need 1 to 2 coats of your new paint.
Most latex primers dry to the touch in 30 minutes to one hour. But for best results, don't paint until the primer completely dries—which can take up to 3 hours, depending on temperature and humidity. Once the primer is completely dry, it's prime time for painting.
In short, you will typically need 2 coats of primer for most painting projects. Apply primer liberally and allow to dry fully before applying your final coat of interior paint. To get more painting advice for your next painting projects, click the link below.
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.
Adding a Second Coat
After your first coat of paint is dry, it's safe to recoat typically after four to six hours. A good rule of thumb is to wait at least three hours to recoat your paint or primer if it's water-based. Waiting 24 hours is best for oil-based paint and primer.

HOW LONG DOES IT TAKE FOR PRIMER TO DRY? Most latex primers dry to the touch in 30 minutes to one hour. But for best results, don't paint until the primer completely dries—which can take up to 3 hours, depending on temperature and humidity. Once the primer is completely dry, it's prime time for painting.
You probably don't need a primer paint if the new coat is the same type as the old paint. For example, both are oil-based. You can just pick the paint color you want and keep going. If the current wall is also smooth and clean, you can head straight for the paint.
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.
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.
If the surface is porous
Both the paper that covers it and drywall mud are compromised by water or moisture when they are not sealed first with primer. This material will literally absorb your paint right into it if you don't prime first.
If sanding is your least-favorite step, then it's certainly possible to paint furniture without sanding. But to do so with favorite results, you should clean the wood's surface AND use a high-quality primer and/or paint. You can also use liquid paint remover to scrape off the old paint.
Peeling paint must be removed prior to applying a fresh coat of paint to ensure proper adhesion.
Summary. For your finish to be vibrant and not dull sanding after primer will ensure that the finish is not excessively dulled when you apply your paint top coat. You will typically use finer grit sandpaper and aim to achieve a smooth wood finish so that you get a fine appearing wood finish when you apply your topcoat.
Primer may look like paint, but it has a different composition. It has more resin and less pigment than regular paint.
