If the wall is in good condition and the paints are chemically the same (both latex, for example), you have a few options when the new paint has the opposite shade of the old paint. You can use a primer to completely cover the old color and then apply 1 or 2 coats of new paint. Are you tired of your old painting job? Moving to a house where you previously lived? You can paint over the old color quickly and easily with a few tricks. The Stack Exchange DIY community explains how to do it.

Can I paint over old paint? That's something our customers ask us all the time. In short, the answer is yes. That is, if the walls below are white, smooth and spotless, which, if you're repainting, they probably aren't. Another key consideration to consider when asking “Can I paint over old paint?” is the state of the walls.

Are they chipped? Are there holes in the surface? Is the water in my cast irreparably damaged? Never attempt to paint an existing wooden surface without preparing its surface. Applying a direct coat of paint to the old coating will not work and will eventually tend to peel off, especially if it has a glossy finish. This painting technique needs to prepare the wooden surface first. If you want to completely cover the old color, you can use a primer and then apply a coat of paint.

It is possible to paint and prime on a single paint, which is a newer option that may be perfect for your situation and even shorten the process. Prepare the paint surface with primer to ensure that the paint adheres well to the surface and you'll have a smooth, clean finish. If that's the case, using a basic matte white primer or emulsion for the first coat (or two if it's too dark) is a more cost-effective option than using the more expensive color paint for all layers. When painting a bathroom or kitchen, wash walls with a solution of approximately three teaspoons of laundry detergent in one gallon of water.

Oil-based paint will not adhere to the existing latex paint layer, so you need to create a kind of intermediary. If you paint on a wall with a paint similar to the previous color, in general, you don't need to prime the existing paint. If you choose a lighter and brighter color than your current paint, you'll need to go one step further to make sure that the color of the old paint isn't visible. To help the paint adhere, sand lightly with fine sandpaper or spray with a matte fixer (which creates a slight dent when it dries).

Milk paint, which you can buy in powder or premixed form, or even prepare it yourself at home, is a biodegradable and non-toxic paint option that is ideal for use on wooden furniture and, if you mix it with an equal part of adhesive agent, you don't need to sand the piece before you start. When you paint on a surface that has had to be repaired or is very dirty (rub it first), color both the paint and the primer the same color. Paint in broad daylight, especially for the final layer, so you can see where you've been and be methodical. It's usually possible to omit the primer when painting a wall just to change its color; existing paint seals the drywall and you should be able to get even coverage and satisfactory adhesion with the primer.
