Characteristics of Exterior Paint This type of paint is exposed to various weather conditions. Therefore, it has to provide protection against moisture caused by rain and snow, and ultraviolet radiation caused by sunlight. It also has to protect against fungal growth. These paints are made to combat fading and mildew. Facing the UV radiation mentioned above, as well as very high temperatures, they need to be fade-resistant. As already mentioned, the resins used for exterior paints are soft. This also makes them very flexible. As such, they don’t easily crack on contraction or expansion. This allows them to survive the ill effects of moisture and temperature changes. By simply changing the sheen, this type of paint can be applied to various substrates. During rain, a house’s exterior absorbs small amounts of water. Flat paint won’t bubble - it will allow the water to escape. As it releases more volatile organic compounds, exterior paint is unsafe for indoor use. Moreover, it requires sunlight to cure. Characteristics of Interior Paint This type of paint is used for decoration and aesthetics. At the same time, interior paint adds properties of dampness prevention, washability and easy maintenance. Interior paint is formulated in such a way that it can withstand abrasion. As it occupies the same space as people, it is also designed to be more delicate than exterior paint. This type of paint resists staining and can be scrubbed. As it doesn’t have to deal with sunlight, it has no fade-resisting properties. Also, it doesn’t need sunlight to get cured. It is also washable. Roller and brush marks, as well as marks and spots left behind by kids and pets, can be easily cleaned. Interior paint needs to have a low amount or zero volatile organic compounds. This reduces health risks and is vital to preserving air quality in one’s home.
