Have you ever found yourself staring at a half-full can of exterior paint, wondering if you could use it for your indoor project? Maybe you’re midway through painting your living room and ran out of interior paint.
Before you open that exterior paint can, let’s answer this important question: can you use exterior paint inside? According to the Environmental Protection Agency, the chemicals in paints can significantly impact indoor air quality, making this question not just about aesthetics but also about health and safety.
The Quick Answer: Not Recommended
While it might seem practical to use leftover exterior paint indoors, professional exterior house painters strongly advise against it. Why? The answer lies in the different formulations of interior and exterior paints, each designed for specific environments and purposes.
Understanding the Difference Between Exterior and Interior Paint
What Makes Exterior Paint Special
Exterior paint is formulated to withstand harsh outdoor conditions. Our team at MACORP knows that homes face everything from scorching summer heat to freezing winter temperatures. That’s why exterior paint contains special additives that help it:
- Resist fading from UV exposure
- Withstand temperature fluctuations
- Repel moisture from rain and snow
- Fight mildew growth
- Remain flexible to prevent cracking and peeling
These properties make exterior paint excellent for protecting your home’s outside surfaces but problematic indoors.
Interior Paint Characteristics
Interior paint, on the other hand, is designed with different priorities:
- Lower VOC (Volatile Organic Compounds) levels for better indoor air quality
- Scuff and stain resistance for high-traffic areas
- Enhanced washability for easy cleaning
- Smoother finish for aesthetic appeal
- Less harsh odors during application and drying
The Risks of Using Exterior Paint Inside
Health Concerns
The biggest issue with using exterior paint inside relates to your health and safety. Exterior paint contains higher levels of VOCs and other chemicals that help it withstand outdoor conditions. These chemicals release gases into the air (a process called off-gassing) that can continue for months after application.
When used in enclosed spaces, these emissions can cause:
- Headaches
- Dizziness
- Eye, nose, and throat irritation
- Respiratory problems
- Worsened symptoms for those with asthma or allergies
As exterior house painters in Milwaukee, we at MACORP prioritize safety in all our painting projects. We understand that what works perfectly outside can be harmful when used indoors.
Performance Issues
Beyond health concerns, exterior paint doesn’t perform well indoors:
- The softer resin that makes exterior paint flexible outdoors can result in a tacky finish that never fully hardens indoors.
- Higher levels of mildewcides can create unpleasant odors in enclosed spaces.
- Exterior paint may take significantly longer to dry inside due to a lack of air circulation.
