EXTERIOR PAINTING

Exterior paint is formulated to handle mildew and fading. Interior paint, on the other hand, is made to allow cleaning and resist staining.

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.
