Emulsion paint

Emulsion is the standard water-based paint used inside homes (in Greece it is simply called "plastic" paint).

It goes on with a roller or brush, the tools wash out with water, and it is the usual choice for living rooms, bedrooms and hallways.

The finish affects both the look and how hard-wearing it is. Matt hides the flaws in a wall best, while satin and glossier finishes wipe clean more easily but show every bump. For kitchens and bathrooms there are emulsions made to stand up better to washing and moisture.
