Emulsion paint is a water-based paint that is widely used for interior walls and ceilings. It is a popular choice because it is easy to apply, quick-drying, and produces low levels of fumes and odor. Emulsion paint is available in a variety of finishes, including matte, eggshell, satin, and high-gloss, making it suitable for a range of different decorating styles. The paint is also relatively easy to clean with soap and water, making it a practical choice for households with children and pets. Emulsion paint is designed to be used on plaster, wallboard, and other porous surfaces, and it is not recommended for use on woodwork or metal surfaces.
