You will want between two and three coats of paint depending on the situation. After the first two coats are applied and dry, take a look to see if the old paint is showing through. You may just need to touch up a few areas, or if lots of paint is showing through, you'll need an entire third coat.
Another question we get asked a lot from DIY painters and other contractors is, “how many coats of paint do I need when painting the interior or exterior of a home. The general rule is that you should use two coats of paint.

Latex paint requires at least four hours before you can add another coat. Wait at least eight to 12 hours before adding another coat of acrylic paint. Oil-based paints require at least 24 hours before you can apply another coat.

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.
There's rarely an issue with waiting too long between coats of standard house paint. While it's typical to recoat within 4-12 hours, some projects allow weeks or even months between coats without any problems. For instance, on larger builds, painters often wait until other trades finish before applying the final coat.
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.
Dimethyl sulfoxide (DMSO) has become more popular since it has a low level of toxicity, making it a safe replacement for methylene chloride and NMP. Opting for a safe active ingredient like DMSO or a manual paint stripping method will be far safer than risking NMP or methylene chloride.
New paint will not improve the adherence of the suspect old paint coating. Rather it is likely to make it slightly worse due to the stresses imparted as the new paint coating dries. Waterborne paints take a few days to develop full adhesion especially if applied in heavy coats in dubious weather.

Generally, you will want a minimum of two coats of paint – this is a good rule of thumb for any wall or ceiling you're painting. You'll rarely get a seamless finish from just one coat of paint, and even if you do, coverage isn't the only goal when it comes to painting a room.
You want to paint a strip that will allow you to get close enough to the adjacent side with your roller but isn't too wide that your wall dries patchy and with visible lines. Make sure that you cut in on every coat of paint that you apply.
