While it might seem like a clever way to save money or score extra durability, using exterior paint for interior projects can lead to more trouble than it’s worth. Formulated to withstand the harsh elements outdoors, exterior paint offers several advantages that can be tempting for indoor use. However, the cons of using exterior paint inside outweigh any potential benefits.

Health Concerns: The Looming Threat of VOCs

One of the biggest drawbacks of using exterior paint indoors is the presence of volatile organic compounds (VOCs). These chemicals are emitted from the paint as it dries and can linger in the air for weeks, even months. Exposure to high levels of VOCs can cause a variety of health problems, including:

  • Headaches

  • Dizziness

  • Nausea

  • Eye, nose, and throat irritation

  • Respiratory problems

While modern paints are constantly being reformulated to reduce VOC content, exterior paints generally have significantly higher levels compared to their interior counterparts. This increased VOC concentration poses a greater health risk in a closed environment like a home.

Aaron Paints, a leading manufacturer known for its commitment to health and sustainability, offers a wide range of low-VOC interior paints that are perfect for creating a healthy and beautiful living space.

The Stench Factor: Dealing with Unpleasant Odors

Another major downside to using exterior paint indoors is the strong odor. The high VOC content that creates health concerns also contributes to a lingering and unpleasant smell. This odor can be especially bothersome in smaller spaces and can take a long time to dissipate completely.

Imagine spending weeks in a freshly painted room that smells like harsh chemicals. Not exactly the relaxing ambiance you’d hope to achieve with a new paint job. Interior paints are formulated to have a milder odor, making the painting process and the following weeks much more pleasant.

A Matter of Finish: When Durability Isn’t Enough

While durability might be the initial draw towards using exterior paint inside, it’s important to consider the type of finish it offers. Exterior paints are often designed with a rougher texture to better withstand the elements. This texture can translate into a less smooth and aesthetically pleasing finish on interior walls.

Interior paints, on the other hand, come in a variety of finishes, from flat to eggshell to high-gloss. This allows you to choose the perfect level of sheen for your desired look and the specific room you’re painting. For example, a high-gloss finish might be ideal for a bathroom due to its easy cleanability, whereas a flat finish would provide a more subtle look for a living room.

Beyond Durability: The Hidden Drawbacks

There are several other factors to consider when weighing the cons of using exterior paint inside. Here are a few additional drawbacks:

  • Limited Color Selection: Exterior paint manufacturers typically offer a narrower range of colors compared to interior paint lines. This can restrict your design options and make it difficult to find the perfect shade for your project.

  • Application Challenges: Exterior paints often have a thicker consistency than interior paints, making them more challenging to apply smoothly. This can lead to a less professional-looking finish, especially for DIY projects.

  • Washability Issues: Interior paints are formulated to be easier to clean and more stain-resistant. This is especially important in high-traffic areas like kitchens and bathrooms. Exterior paints might not hold up as well to everyday wear and tear.

Conclusion: Invest in the Right Paint for the Job

While exterior paint might seem like a cost-effective option at first glance, the potential health risks, unpleasant odors, and lack of design versatility ultimately outweigh any perceived benefits. For a healthy, beautiful, and long-lasting interior paint job, invest in high-quality interior paint specifically formulated for your project.

Frequently Asked Questions (FAQ)

Q: Can I use leftover exterior paint for a small touch-up job inside?

While it might not be ideal, a small amount of leftover exterior paint for a minor touch-up is unlikely to cause significant health problems. However, it’s still recommended to use interior paint whenever possible for optimal results.

Q: Are there any situations where using exterior paint indoors might be acceptable?

In very rare cases, such as painting a non-living space like a garage or storage room, using exterior paint might be acceptable. However, ensure proper ventilation during and after application.

Q: What should I do if I accidentally used exterior paint inside my home?

If you’ve already used exterior paint indoors, prioritize ventilation by opening windows and doors. Consider using fans to circulate air. If concerned about health risks, consult a medical professional. For future projects, always use interior paint for indoor spaces.
