What Is The Difference Interior And Exterior Paint

To understand the difference between interior and exterior paint one needs to understand paint chemistry.

What is the difference interior and exterior paint. The major difference between interior and exterior paint is found in the additives and resins. In the exterior paints are exposed to heat rain and other freezing conditions. Here are the main differences between interior and exterior house paints.

Interior paint is used with a different resin than exterior paint. The core difference between the interior and exterior paints is the resin used to bind the paint to the surface. Exterior paint may also contain more pigment.

Characteristics of exterior paint. Interior and exterior paints have similar solvents and pigments. Interior paint is most commonly water based latex and is available in a variety of finishes with the most common being flat low luster and semi gloss.

But the real difference between them can be found in the additives and the resin. Exterior paints have to withstand sun and weather conditions without peeling. Not only this but they are made with zero or fewer voc s.

One of the most important differences though is their relative level of volatile organic compounds or vocs. Exterior paints need sunlight to cure while interior paints get cured without direct exposure to sunlight while one can apply interior paint himself hiring the services of professional painters is a must for a decent application of exterior paints. Paints with higher levels of vocs are reserved exclusively for use outdoors.

Interior and exterior paints have similar solvents and pigments though some pigments fade faster than others and so are more commonly used in interior formulations. Painting your house can be a challenging task so you don t want to mess it up by choosing the wrong type of paint. Whereas interior paints must resist abrasion.
