Differentiating Interior and Exterior Paints to Help You Choose the Right Paint

by Danny White

Before choosing an interior and exterior paint, you should be aware of the ingredients and their behaviour in different conditions. Your exterior is exposed to sunlight, dirt, and water whereas the interior must withstand scratches, oil and mineral deposits and moisture. Your basic knowledge about paints will help you choose the right combination for your interior and exterior wall paintings.

The can of paint contains solvents, pigments, resins, and additives. The solvents like water and white spirits are used to make the paint thin for painting. The pigments are responsible for different colour shadings whereas the resins help in binding the colour to the painted surface. The additives usually improve the drying time, weather resistance and fungus resistance properties of the paint.

Here are few important differences to consider while choosing paints:

  1. Resin contents: The interior paint should have rigid resins to provide protection against scratches and stains. The adverse outer temperature condition results in tearing off the wall paint. To avoid this, the exterior paints has soft resins. This soft resins also help the exterior paint to resist against fading and chipping due to sunlight.
  2. Latex and alkyd paints: The latex paints and alkyd paints (oil-based paints) are the main types of paints available in the market. The latex paints have different level of volatile organic compounds (VOCs) based on whether they are used for interior or exterior painting purpose. The alkyd paints are used only for exterior painting as they have large inert molecules that reacts with oxygen to form a hard film. It also has harmful health effects. The latex paint for exterior contains high level of VOCs compared to zero or fewer VOCs in the interior paint to withstand harsh weather conditions.
  3. Additives: The exterior paints have heavy duty additives to withstand sunlight, wind and rain water pressure. They also retain the colour of the paint despite such seasonal changes. The interior additives are designed to give bright and shiny look to the walls, but the exterior additives are designed for naturally occurring adverse conditions. The exterior additives provide thicker coating and are less decorative than interior paints’ additives.
  4. Nature of exterior and interior paints: The interior paints are more delicate, shiny, decorative, and attractive than exterior paints. The reason is exterior paints are made for safety rather than decorative purpose. You should not use exterior paints for interior as they release harmful gases. The load bearing pillars, outdoor furniture and walls of parking lot can be painted with exterior paints.

There are few brands confirming that their paints can be used for both exterior and interior paintings. It is advisable to take a professional painter guidance as he can evaluate the exact VOCs level in the paints.
