Last year when I painted the exterior of my house, I discovered 2 fresh, and non used exterior paint cans. Hence, I decided to paint the interior of my house using this. But my house painter said that there is a difference between interior paint and exterior paint, and I cannot use the exterior paint on the interior surface.

What is the Difference Between Exterior and Interior Paint?

The main difference between exterior paint and interior paint is that the paints used inside homes are made especially for interior use and are made to endure the normal indoor environment. Exterior house paints, however, might not work as well indoors because they are designed for outside use.

After mentioning the difference in exterior and interior paint, he also highlighted the downside of applying exterior paint on the interior,

There are various drawbacks when applying exterior paint indoors. Higher concentrations of volatile organic compounds (VOCs), which are linked to poor indoor air quality, may be present in outside paint.

  • VOC: Exterior paints include chemicals called volatile organic compounds (VOCs), which can evaporate and lead to air pollution and other health hazards.

  • Odour: Because exterior paints have different formulas and may include greater quantities of volatile organic compounds (VOCs), using them indoors might cause unpleasant scents.

It is because of these reasons I finally did not apply the exterior paint on my interior walls.

Hi there, there are quite a lot of difference between interior paint and exterior paint. I’ll try to share most of them with you here to help answer your question.

We got our house interiors and exteriors painted before Diwali, so I have quite some understanding of the differences these two hold. 

What is the Difference Between Exterior and Interior Paint?

Here are the differences between the exterior and the interior paint. I have also mentioned the criterion based on which the differences are drawn for your ease of understanding.

Criterion

Exterior Paint

Interior Paint

Usage

The exterior paint is used for painting the exterior of a place.

Interior paint is used for painting the interiors of a place.

Formulation

These are water resistant and come with UV protection for long term coverage.

These are durable and scrubbable for ease of cleaning.

Binding Resins

The binding resin is softer to resist fading, chipping and peeling.

The resin is comparatively rigid to reduce scratches and smudges. 

VOC 

They contain more VOCs.

They have much lower VOC concentrations.

The properties of these two paint types are based on their usage and the environment. This is why it becomes important for you to use exterior paints for exterior work and interior paints for interior work. 

This is all about exterior paint vs interior paint. I hope this will help you understand the two better.
