Exterior and interior paint are two different types of coatings used for different purposes. The primary difference between exterior and interior paint is that exterior paint is designed to stand up to the elements and protect the surface from the sun, rain, and other environmental conditions, while interior paint is designed for aesthetics, to make the interior of a home or building look more attractive.
Exterior paint is generally more durable than interior paint due to its formulation, which includes ingredients that help it to resist the elements. The components of exterior paint are designed to resist the effects of weathering, and the paint includes UV inhibitors and fungicides to protect it from the sun’s rays and from mold and mildew growth. Exterior paint is also formulated to resist fading from the sun and to be more mildew-resistant.
Interior paint is designed for aesthetics, not for durability. It is formulated to provide a good finish on walls and ceilings without the need for additional protection. Interior paint is typically less expensive than exterior paint, because it does not need to be formulated to withstand the elements.
Another key difference between exterior and interior paint is the way it is applied. Exterior paint is usually applied with a brush or roller, while interior paint is usually sprayed or brushed. Exterior paint is usually thicker and more opaque, while interior paint is usually thinner and more translucent.
Finally, exterior paint is designed to withstand the elements, while interior paint is designed to look good and last longer. Exterior paint is formulated to resist fading and mildew, while interior paint is formulated to resist staining and fading. Exterior paint is also usually more expensive than interior paint.
In conclusion, exterior and interior paint are two distinct products designed to fulfill two different purposes. Exterior paint is designed to protect the surface from the elements, while interior paint is designed for aesthetics. Exterior paint is usually applied with a brush or roller and is more opaque, while interior paint is usually sprayed or brushed and is more translucent. Additionally, exterior paint is more expensive than interior paint.

Exterior vs Interior Paint: Durability
The main difference between exterior and interior paint lies in the durability of each. Exterior paint is designed to withstand extreme weather conditions, from extended periods of rain and sun to intense heat and cold. It is also designed to prevent mold, mildew, and other forms of deterioration. Exterior paints come in a variety of finishes, including flat, satin, and gloss. Flat paints are the least durable and are best used in low-traffic areas like garages and sheds. Satin and gloss finishes are more durable and can be used on wood, metal, and other surfaces.
Interior paint, on the other hand, is designed for interior use only. It is formulated to last for several years, but it is not designed to withstand the same environmental conditions as exterior paint. Interior paint comes in a variety of finishes, from flat to eggshell to high-gloss. Flat and eggshell finishes are the most durable and are best for high-traffic areas like living rooms and hallways. High-gloss finishes are the least durable, but they offer a bright, shiny finish.
Exterior vs Interior Paint: Sheen
Another difference between exterior and interior paint is the sheen. Exterior paint is typically available in flat, satin, and gloss finishes. Flat finishes offer a matte, non-reflective finish, while satin and gloss finishes offer a bit of sheen. Gloss finishes are the most reflective and offer the highest level of protection against the elements.
Interior paint, on the other hand, is available in a wide range of sheens, from flat to eggshell to high-gloss. Flat and eggshell finishes are the most popular and are best for high-traffic areas like living rooms and hallways. Eggshell finishes offer a subtle sheen while still providing a durable finish. High-gloss finishes are the least durable, but they offer a bright, shiny finish.
Exterior vs Interior Paint: Cost
The cost of exterior and interior paint can vary significantly. Exterior paint is typically more expensive than interior paint due to its more durable formulation. It is also more labor-intensive to apply and requires more preparation. For these reasons, exterior paint usually costs significantly more than interior paint.
Interior paint, on the other hand, is typically less expensive than exterior paint. It is less labor-intensive to apply and requires less preparation. Interior paint also comes in a wide range of colors and finishes, so it is easier to find the right color and sheen for your project. For these reasons, interior paint is usually the more affordable option.
