What You Need to Know About Interior and Exterior Paint
Let us first understand the distinctions between interior and exterior paints is crucial for achieving a durable and aesthetically pleasing finish. Here’s a concise overview of their differences:
| Aspect | Interior Paint | Exterior Paint |
|---|---|---|
| Composition | Formulated with rigid resins for durability and easy cleaning; low in VOCs for indoor air quality. | Contains flexible resins to withstand weather changes; higher in VOCs due to added chemicals for durability. |
| Durability | Designed to resist stains and scuffs; suitable for areas with less exposure to harsh conditions. | Designed to withstand harsh weather conditions, UV exposure, and moisture, with added ingredients to resist fading and mildew growth. |
| Finish Options | Available in various sheens: matte, eggshell, satin, semi-gloss, and gloss. | Typically found in flat, semi-gloss, or gloss finishes; fewer options compared to interior paints. |
| Drying Time | Dries faster due to lower VOC content; allows for quicker recoating. | Longer drying times because of higher VOC levels and thicker formulation. |
| Application Areas | Ideal for indoor spaces like living rooms, bedrooms, and kitchens. | Suited for outdoor surfaces such as siding, fences, and exterior doors. |
Note: VOCs (Volatile Organic Compounds) are chemicals that can release harmful gases. Interior paints are formulated to minimize these emissions for safer indoor air quality.
Selecting the appropriate paint type for your project ensures longevity and maintains the desired appearance of your surfaces.
Can I Use Exterior Paint Inside?
Let’s address the big question: Can I use exterior paint inside? The short answer is technically yes, but it’s a bad idea.
Exterior paint is specifically designed to endure harsh weather conditions, from scorching sun to heavy rain. To achieve this, manufacturers add resins and fungicides that make the paint flexible, durable, and resistant to mildew. Unfortunately, these same additives come with a cost: high VOCs.
VOCs are chemical compounds that evaporate into the air, causing that strong paint smell we all recognize. Indoors, these fumes can linger, posing health risks to people with allergies, asthma, or chemical sensitivities. Even after drying, exterior paint can continue off-gassing, making your home environment less healthy.
In short, using exterior paint inside is not worth the potential headaches, especially if you want a safe and breathable indoor space for your family. Learn more about low-VOC Paint vs regular paint here.
Why You Shouldn’t Use Interior Paint Outdoors
If you’re tempted to use leftover interior paint on an outdoor project, don’t do it. While interior paint is great for smooth, controlled indoor conditions, it’s not made to handle outdoor challenges like fluctuating temperatures, UV rays, and moisture. Here’s what can happen:
- Cracking and Peeling: Without the resins found in exterior paints, interior paint can’t expand and contract with temperature changes.
- Fading: Sunlight will quickly wash out the vibrant color you worked hard to achieve.
- Mildew and Mold Growth: Interior paint lacks the protective agents needed to deter these issues.
Using interior paint outdoors will cost you more time and money in the long run as you’ll need frequent touch-ups or complete repaints. Exterior paint types are formulated with weather-resistant resins and additives to ensure durability.
The Best of Both Worlds: Interior/Exterior Paints
What if you’re tackling a project that blurs the lines, like a screened-in porch or a heavily trafficked area? That’s where interior/exterior paints shine. These hybrid paints combine the durability of exterior paint with the low-VOC formulation of interior options.
However, keep in mind that these paints aren’t perfect for every situation. While they work well in high-traffic areas like trim, baseboards, and doors, they’re often overkill (and more expensive) for standard interior walls and ceilings. We recommend saving these for areas that really need extra durability.
