Interior vs Exterior Paint: Which Is Better for Your Home?

Painting is a simple and effective way to give your home a new look. Whether you want to refresh your living space or boost your home’s curb appeal, choosing the right type of paint is crucial. Two main types of paint are available in the market; interior and exterior paint. 

While they may seem similar, there are some key differences between them that you should know before making a decision. Here are some of the ones worth considering:


Interior and exterior paints are made up of different compositions. Interior paints are formulated to create a smooth and even finish. They are made with a blend of vinyl, acrylic, and other polymers that provide great coverage. Interior paints are also low in volatile organic compounds (VOCs), which makes them less odorous and safer to use indoors.

Exterior paints are designed to withstand harsh weather conditions. They contain more resins, pigments, and additives that help them resist fading, chalking, and peeling. Exterior paints are also more durable and have higher levels of VOCs than interior paints.


Another difference between interior and exterior paints is their colour selection. Interior paints come in a wide range of colours and finishes, from matte to glossy. You can choose any colour that fits your style and personality without worrying about the effect of sunlight. Interior paints are not exposed to direct sunlight so they won’t fade over time.

In contrast, exterior paint colours are limited by their exposure to sunlight and weather. The sun’s ultraviolet rays can cause exterior paint to fade, so choosing colours that can withstand fading is important. Lighter colours tend to fade faster than darker ones, so you may need to repaint more frequently. That being said, pick a colour that complements your home’s architecture and the surrounding landscape.


Different paints require different application methods. Interior paints are easy to apply and can be brushed, rolled, or sprayed on. They dry quickly and are easy to clean up with soap and water. If you’re painting a smaller space, you can even use a paintbrush to do the job.

Exterior paints require more preparation and effort to apply. The surface must be cleaned and primed before painting to ensure proper adhesion. Exterior paints need to be applied in a specific temperature range, typically between 10°C and 30°C. If the temperature is too low or too high, the paint may not bond properly, leading to peeling or cracking.


Cost is another factor to consider when picking between interior and exterior paints. Interior paints are generally less expensive than exterior paints. This is because they require fewer additives and resins and fewer durability requirements. However, the cost of interior paint varies depending on the quality and brand you choose.

On the other hand, exterior paints are more expensive than interior paints because of their durability and weather resistance. They require more additives and resins that make them more costly to produce. Bear in mind, however, that the price of exterior paint also varies depending on the quality and brand you choose.

The Verdict

Choosing between interior and exterior paint depends on your needs and preferences. Interior paint is excellent for refreshing your living space and adding a personal touch to your home. Exterior paint is ideal for protecting your home from the elements and boosting its curb appeal. Whether you’re painting a room or your entire house, make sure to choose the right type of paint for the job.
