While sanding is not required for every paint project, rough spots on walls, whether they have been previously painted or not, need to be sanded before they are painted to ensure the paint goes on smoothly.
There are times you can skip it, but sometimes not so much. If the finish of the piece you are painting is damaged or chipping in any way, then always sand first. If you try to paint over that, then your new paint job will start chipping off almost as soon as you paint it on there.
Milk paint, which you can purchase as a powder or premixed, or even whip it up yourself at home, is a nontoxic and biodegradable paint option that's great for use on wood furniture—and if you mix it with an equal part of bonding agent, you don't need to sand the piece before beginning.
Annie Sloan's brand of furniture paint will adhere to most surfaces without any sanding first. Chalk Paint® has incredible sticking power so it really doesn't need any surface prep in the vast majority of cases. You can even paint directly over hardware, if you wish.
Mineral Paint: Similar to chalk paint, but often more expensive. Top coat recommended. Milk Paint with bonding agent: Also does not require sanding or priming, however the colors are limited and you have to mix your paint/bonding agent well.
Using Oil Bond: The Latex Paint Additive
Particularly in places like kitchen cabinets, bathroom cabinets, trim, doors, built-ins, painted furniture and windows, Oil Bond gives painters the ability to create powerful, professional-grade adhesion, all without sanding or priming.
Always prime your walls before painting if the surface is porous. The surface is porous when it absorbs water, moisture, oil, odors or stains. For example, brand new drywall is a very porous material.
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.

Luckily you can simply spray paint it. As a whole, spray paint can be used on wood.

But most spray paints will stick to wood and the results are just as good as with regular paint.
As a general rule, it is possible to paint over already painted wood without sanding it first if the surface is not damaged or the previous paint job is not peeling or chipping off. Simply prepare the surface by applying a high adhesion primer. Once the primer has fully dried apply the paint.
Paint can be applied over wood surfaces, but it is not a good idea to use it over furniture made of wood. This means you should not buy wall paint to use over furniture made of wood. However, wall paint is not a suitable paint option for wooden surfaces, so you should avoid using it.
