Yes, you can paint matte over satin finishes. It is important to properly prepare the surface by cleaning and sanding it before applying the matte paint to ensure good adhesion.
Yes, you can paint flat paint over satin paint as long as the surface is properly prepared and primed.
If it has a matte finish it should be easy to paint over.

To transform glossy paint into a matte finish, you can lightly sand the glossy surface to create a rough texture, then apply a matte topcoat or finish over the sanded area. This will help to dull the shine and create a matte appearance.
You typically do not need primer when painting satin paint over existing satin paint, provided the surface is clean, in good condition, and the colors are similar. However, if the existing paint is in poor condition or if you're making a significant color change, using a primer can help ensure better adhesion and coverage. Always clean the surface before painting to achieve the best results.
Clear primer.
More important is, that both paints are of the same kind (like: oil-based paint, acrylic paint, latex paint). Semi-gloss is more easily painted over then high gloss, but first better find out what the old paint layer is made of. Check with the help of alcohol - if paint comes off in any way when you rub it with a cloth of alcohol, it's latex or acrylic paint (and can be painted over with acrylics).
Yes, you can paint over acrylic paint with gouache, as gouache is water-based and can adhere to acrylic surfaces. However, for the best results, ensure that the acrylic paint is fully dry before applying gouache. Keep in mind that gouache is more opaque and may not adhere as well to glossy finishes, so consider using a matte medium or a light sanding on the acrylic surface if needed.

Always prime first and make sure to key (sand) all surfaces, whether you are priming or not that is VERY important.The rule is: You cannot use water base paints over oil base paint. You may if you prime first. If your matte and your gloss are both water based, you may use the matte. When in doubt, please prime first.AnswerBeing in the painting business for nearly 10 years, the key factor to painting waterbase paint (in any sheen) over oil base paint is to sand, sand, and sand again. A regular primer will not add any adhesion to the surface - you need a high adhesion primer that is either oil or shellac base first, or a waterbase that is made specifically to grip to oil. Of course, I would skip this step entirely simply by sanding thoroughly - and using a waterbase topcoat that is good quality. Ideally you should use a paint that is made to stick to oil, such as General Paint's HP2000 or Dulux Diamond. But priming with a regular waterbase primer will not help to solve this problem and will be a waste of your time and money.
To dull the finish of gloss paint and achieve a satin or eggshell appearance, you can lightly sand the surface using fine-grit sandpaper (around 220 grit). Be sure to sand evenly to avoid creating uneven patches. Alternatively, you can apply a matte or satin finish clear coat over the gloss paint, which will reduce its shine while preserving the underlying color. Always clean the surface before applying any additional product for the best results.
Yes, that would work as a painting technique.
