A Brief Introduction On Painting
Difference Between Exterior and Interior Paint Here are a few popular differences between exterior and interior paint:
1. Composition Interior Paint: Designed for controlled environments, interior wall paint usually contains fewer weather-resistant additives. Its formulation is more about maintaining a pleasant appearance than enduring severe weather conditions. It faces less exposure to outdoor elements and focuses on providing a clean and fresh look.
Exterior Paint: Specifically engineered for exposure to harsh outdoor elements, exterior paint contains additives that resist weathering, damage from UV rays, moisture, and severe temperature changes. It is formulated to withstand rain, sun, snow, and extreme climate conditions.

2. Durability and Resistance Interior Paint:
It is designed to resist everyday wear, like stains and smudges. You will not have to worry about common indoor impacts like spills, marks, and frequent touches. It aims at retaining its look and being easy.
Exterior Paint: It is designed for heavy-duty resistance against harsh outdoor conditions like direct sunlight, heavy rain, fluctuating temperatures, and moisture. This type is meant to protect your house against weather elements and maintain long-lasting paint colour for your home.
3. Colour and Finish Interior Paint: You will get interior wall paints in a wide range of colours and finishes. Therefore, people can easily create any interior decor style as per their preferences.
Exterior Paint: The colour and finish options available for exterior paints are limited when compared to interior wall paints. Exterior paints are formulated keeping in mind that they will face prolonged exposure to sunlight. Some colours and finishes are not appropriate for this. The goal is to preserve the colour and aesthetics under intense weather conditions.
4. Resistance to Mould and Mildew
Interior Paint: Although some interior paints have anti-microbial properties, they are not as extensive as exterior paint due to less exposure to moisture. They aim at preventing mildew and mould growth in areas with higher humidity, such as bathrooms and kitchens.
Exterior Paint: It contains stronger anti-mold and mildew elements due to greater exposure to damp conditions. This is designed to combat moisture-related issues effectively in various climates.
5. VOC Levels
Interior Paint: VOCs are harmful to your health. This is why interior paints always have a low VOC content.
Exterior Paint: Exterior paints have a higher concentration of VOCs when compared to interior paint. VOCs make it easier to spread paint and fasten the drying process. This makes the painting task easier.
6. Coverage and Application
Interior Paint: It provides smoother application and better coverage and often requires fewer coats for a polished finish. Its formulation is focused on achieving good and even coverage.
Exterior Paint: It is formulated for robust coverage and strong adhesion on various surfaces. More prep work and multiple coats are required to withstand outdoor conditions. This paint type can cover diverse surfaces, such as wood, stucco, brick, and siding.
7. Drying Interior Paint: The interiors of your home do not get sufficient sunlight. This is why interior wall paints are designed to dry up quickly so that you do not face a lot of inconvenience.
Exterior Paint: The drying time required by exterior paint is comparatively longer. If it does not receive exposure to sunlight, the paint may take a long time to dry up.
