Choosing the right paint finish depends on the area's function, traffic, and desired aesthetic. For high-traffic areas like hallways and kitchens, opt for a durable, washable finish like satin or semi-gloss. Eggshell or satin finishes work well in living rooms and bedrooms, offering a balance between durability and aesthetic appeal. Matte or flat finishes are suitable for ceilings and low-traffic areas, providing a smooth, non-reflective surface. Consider using a moisture-resistant paint like satin or semi-gloss in bathrooms to combat humidity.
