Water-based paint, such as latex or acrylic, is the most commonly used type of paint in houses, especially for interior walls and ceilings. This is because water-based paint is easy to apply, dries quickly, and produces low levels of fumes and odor. It is also easy to clean up with water. However, oil-based paint may be used for certain high-traffic or high-moisture areas, such as kitchens, bathrooms, and trim, because it is more durable and resistant to wear and tear. Additionally, oil-based paint is typically used for exterior surfaces because it is more durable and resistant to weather and environmental conditions.
