Manufacturers have made paint more durable and stain-resistant by decreasing its what?

The effectiveness of paint in resisting stains and enhancing durability is directly linked to its porosity. By decreasing the porosity of paint, manufacturers reduce the size and number of the microscopic pores within the paint film. This development results in a surface that is less prone to absorbing stains, moisture, and other contaminants, thereby making it more durable and easier to clean.

When paint has lower porosity, it can maintain its appearance and integrity over time, as it is less likely to harbor dirt and grime. This is particularly important in environments where surfaces are subject to various stresses, including abrasion and exposure to cleaning chemicals. As a result, the improvements in paint technology that focus on reducing porosity contribute significantly to creating finishes that are both aesthetically pleasing and long-lasting.
