Differences Between Interior and Exterior House Paint

Paint is a crucial element in enhancing the beauty of a house. It can be used to coat walls, door frames, tiles, fences, and furniture. There are two main types of house paint: interior paint and exterior paint. This article will discuss the differences between the two.

Key Differences

As the names suggest, the primary difference lies in their intended use. Interior paint is specifically designed for the inside of a house, while exterior paint is made for the outside.

Beyond that, there are key differences in the types of resin and additives used in each type of paint.

Interior Paint

Interior paint is formulated to resist scuffs and marks and is easy to clean. It uses a more rigid resin, making it less prone to scratches and scuffs. Interior paint can be easily cleaned with water and soap.

While it has a lower durability compared to exterior paint, interior paint is made with safer materials. It has a low VOC (Volatile Organic Compounds) content. VOCs are substances that release harmful gas when inhaled by humans. The low VOC content of interior paint minimizes the risk of respiratory problems caused by the gas emitted by the paint.

Exterior Paint

Exterior paint is specially designed to withstand all kinds of weather changes, UV rays, and moss. Therefore, it is made with a more flexible resin that can endure temperature changes that can damage paint (expansion/contraction).

Unlike interior paint, exterior paint has a higher resistance to various temperatures, impacts, and weather conditions. Exterior paint has a higher VOC content than interior paint. Since exterior paint is used outdoors, the emitted gas will dissipate into the air, minimizing respiratory problems.


Those are the differences between interior and exterior paint. Hopefully, this information is useful, especially for those of you who are choosing paint for your house.
