Finishes play an important role when it comes to interior painting, as they help to protect the walls. Some variety of finish, even help to conceal the imperfections of the wall, while some tend to magnify them. Some finishes allow scrubbing, while some don't stand cleaning.
Satin paint finish is a type of finish. It is between the matte/flat paint finish and the glossy finishes. Hence, it seems like a good choice of finish. Let us discuss first what a matte finish or flat finish is. Flat paint gives a non-reflective finish to the wall. It is very much suited for walls which have imperfections.
Flat or matte paint due to this particular attribute is the preferred choice for walls which have imperfections like cracks, gaps, uneven surfaces, etc. However, this paint can't be scrubbed or cleaned, and so is not suitable for high traffic areas of the house.
Another finish which lies between matte and satin finish is the eggshell paint, which has no sheen like flat paint, but withstands wear and tear better than flat finish. Main difference between satin and eggshell finish is that, satin paint has a little sheen to it, but it can withstand a little better than eggshell paint, and can be cleaned mildly.
Satin-painted surfaces can't be cleaned with abrasive cleaners, but you can do mild cleansing on them. Occasionally, to get rid of dirt on the wall surfaces you can perform cleaning of the satin-painted surfaces, with mild cleaning products.
It is affordable and you can easily find it on the shelf. Make sure you read the label properly to find the variety or shade of satin paint of your choice.
However, when performing paint job on kitchen room, avoid painting the wall trims with it. For the wall trims go with semi-gloss finish, as wall trims tend to get dirty and grimy very soon. For this purpose a semi-gloss finish is a good idea as it allows cleaning. Avoid using satin finish for bathrooms.
You can also use satin finish for interior surfaces as well as outdoor surfaces. Because, of its glossy nature this finish protects the exterior walls from sun damage. It can also be used on wooden furniture and aluminum siding.
