Flat paint, also known as matte paint, has a non-reflective finish that absorbs light rather than reflecting it. This type of paint is often used for interior walls because it helps hide imperfections and provides a smooth, uniform appearance. It is available in various colors and can be applied easily with brushes or rollers. One downside of flat paint is that it is less durable than other finishes, such as eggshell or semi-gloss. It can be more challenging to clean, as scrubbing may damage the surface. However, flat paint is ideal for low-traffic areas where a soft, elegant look is desired.
