Imagine this: you started your first ever DIY paint project, excited to finally add a fresh new coat of paint to your home. But half-way through the job, you realize you used the wrong type of paint! You used the exterior paint inside and now your home is filled with hazardous fumes and isn’t curing properly. Now you’re stuck with a mess on your hands and have even more issues to deal with. Interior vs exterior paint, that’s the question!

When it comes to painting your home, it’s important to choose the right type of paint for the job by consulting with exterior painting companies. Depending on whether you’re painting the exterior or interior of your home, there are different types of paint that should be used.

Here’s a look at the differences between exterior and interior paint, and what you need to know about each so you can make your home the one of your dreams.

How They Differ

Besides the obvious — interior is inside and exterior is outside —  there are a few key differences between exterior and interior paint that will help you choose the right type of paint for your project before contacting any exterior painting companies.

Withstanding the Elements

Exterior paint is designed to withstand the elements like harsh weather, while interior paint is not. That’s why exterior paint often contains ingredients like weatherproofing agents and ultraviolet inhibitors since it is for the outside of your home and therefore, will experience more harsh conditions.

If you choose to use exterior paint for the interior of your home, it will be more likely to peel and chip due to the fact that it wasn’t designed for those conditions since it is heftier than interior paint in order to provide that protection. The makeup of exterior paint itself makes it recommended for external use only.


Exterior paint usually has a higher sheen than interior paint, which helps it resist mold, mildew, and other environmental damage. If used inside, this sheen can make imperfections in your walls more noticeable due to the extra light reflection.

Cost Difference

The difference in cost is evident between the two. Interior paint tends to be the cheaper option due to the fact that exterior paint needs to be able to withstand more wear and tear, meaning there are often more ingredients involved in the production.

The cost will vary depending on the square footage of your project and the quality of paint you choose, but exterior paint will always be more expensive than interior paint – there’s much more included in it to add protection. Not to mention, the labor of getting the job completed efficiently will be added, and will depend on the exterior painting companies.
