What’s the Difference Between Exterior and Interior Paint? | A Straightforward Guide for Bergen County Homeowners

Ever found yourself wondering, “Can I use exterior paint on my living room walls?” or “Will interior paint hold up on my shed?” If so, you’re definitely not alone. We hear these questions all the time from homeowners across Ridgewood, Tenafly, Closter, and Paramus.

To help clear things up, here’s a simple, no-jargon breakdown from the pros at MGP Painting Inc.—so you know exactly what to use, where, and why it matters.

1. Two Different Jobs = Two Very Different Paints

Exterior Paint

This stuff is made to take a beating from the elements—rain, snow, blazing sun, even those wild Bergen County winters. It’s built with:

  • Flexible resins that help it expand and contract with temperature swings

  • Additives that protect against mildew, UV rays, and fading

  • Strong smells and higher VOCs (not safe indoors!)

  • Ideal for surfaces like siding, stucco, brick, shutters, and exterior trim

Interior Paint

Designed for the calm, climate-controlled world inside your home. It’s:

  • Lower in VOCs, safer to breathe indoors

  • Easier to clean and touch up

  • Made to resist stains and scuffs from everyday life

  • Best for drywall, ceilings, trim, and doors

For homeowners in Bergen County, choosing the right product can be tricky. If you're still unsure about which paint to choose, don't worry—our Bergen County Painting Service can guide you through the best options. Whether it’s for your home's exterior or a specific room, we ensure you make the right decision and avoid the hassle of repainting.

2. So… Can I Use Exterior Paint Inside?

Technically? Yes. 

Should you? Nope.

Here’s why:

  • It releases strong fumes that aren’t safe in enclosed spaces

  • It doesn’t look or feel as smooth on interior walls

  • It’s basically over-engineered for indoor use—you’re paying extra for weatherproofing you don’t need

When it comes to painting rooms where people live, sleep, or work—especially in family homes around Closter or Paramus—interior paint is the way to go. We typically recommend a satin or eggshell finish for most walls. If you're looking for a specific recommendation, our interior house painting services can provide expert advice.

3. What Happens If I Use Interior Paint Outside?

Short answer: it’s not going to last.

Interior paint exposed to sun, rain, or freezing temps (hello, Ridgewood winters) will:

  • Fade fast

  • Crack and peel

  • Possibly grow mildew

If you've already painted a garage or porch with the wrong type of paint, it might need to be sanded and redone using an exterior-grade product. Popular choices for the local area include Benjamin Moore Aura or Sherwin-Williams Duration. These products are perfect for your exterior house painting needs, providing durability and long-lasting results.

4. What About Covered Spaces Like Porches?

Ah, the gray area—literally.

If you’ve got a screened-in porch or covered sunroom, you might be tempted to use interior paint. In some cases, that can work. But for the best protection, we often recommend a low-VOC exterior paint or a versatile hybrid formula meant for indoor-outdoor use.

This way, you get durability and breathability—ideal for semi-exposed spaces in homes around Closter or Tenafly. For expert guidance on selecting the right paint for your specific needs, feel free to reach out to the best painters in Bergen County.
