                              Difference between interior and exterior paint

 Getting your house painted might be an overwhelming task.

Choosing the right color and shade is a difficult and selecting the paint becomes even more difficult when there are different types involved.

In this article we will explain about the difference between interior paint and exterior paint, so that you would know what kind of paint goes where and why?

This will help you in the selection process.

  The purpose of interior and exterior paints are different.

 Though we paint for protection and decoration purposes there are certain qualities that are required, which are different when it comes to the indoors and               outdoors.

 For interior paint we consider the fact that it should be resistant to staining, be cleaned easily and could be scrubbed.

 Whereas exterior paint should be able to withstand the different weather conditions, should be resistant to fading etc.

Thus, the components of both the paints would differ in order to allow the paints to perform their specific functions.

The common components of any paint are pigments, solvents, additives and resins.

The solvent could be oil or water.

The solvent evaporates as the paint dries.

The pigment is the component which lends the color to the paint and is bound to the surface by resins.

 In both types of paints i.e. interior and exterior the solvents and pigments share similarities. One can use oil-based or water-based solvent for exterior but the use of   oil-based solvent is avoided indoors because of the odor.

 Another primary difference between the interior and exterior paints is the resin.

 In an exterior paint, the paint should be able to survive temperature changes and exposure to moisture.

 It should be tougher and be resistant to peeling, fading.

Thus, the resins must be softer.

Whereas in the case of interior paints, the temperature is not a problem thus the resins can be more rigid.

Exterior paints shouldn't be used indoors as they continue releasing harmful compounds.

One should choose a flat sheen exterior paint as this will allow the surfaces to breathe.

  Interior paints are safer to use indoors.

There should be adequate ventilation while painting is going on and one must also ensure that ‘deep cleaning’ or ‘building flush out’ is adequately done, as it goes a long way in making the building safe for occupancy.

  On the other hand using interior paints on the exterior surfaces also doesn’t serve the purpose, as they lack certain additives which make exterior paint resistant to     the elements.

 Thus, as we have seen interior and exterior paint differ on the basis of their properties, the purposes they serve, their uses and therefore we can’t use the exterior   paints for interior surfaces and likewise it is not recommended to use interior paints on the external surfaces.

 So, now you know that exterior paints need to be used on the exterior surfaces and outdoors,

Whereas for interior works interior paints must be used.

 If you like a particular color indoors and want the same thing for the exterior also, be sure to remember that paints look different according the light they are viewed in.

 So get a similar shade and try it out in patches to know which shade suits your taste and requirement.

This way you can have the same shades and colors are interior and exterior paints but don’t make the mistake of using the same paint for both outdoors and indoors.

Choosing the right color and shade is a difficult and selecting the paint becomes even more difficult when there are different types involved.
