Can I Use Exterior Paint on the Interior?

 

When you're planning your next home renovation or touch-up, you might be tempted to use whatever paint you have on hand — even if it's exterior paint. But is it a good idea to use exterior paint inside your home? Let’s dive into the pros, cons, and best practices, especially if you're considering hiring professionals like Painters near Roswell or trusted Painting companies near Roswell such as Dunwoody.

What’s the Difference Between Exterior and Interior Paint?

The main difference lies in formulation and durability. Exterior paint is designed to withstand harsh weather conditions like UV rays, rain, and temperature fluctuations. It contains strong chemicals, additives, and mildewcides to handle outdoor stressors.

Interior paint, on the other hand, is formulated with indoor air quality and aesthetics in mind. It's less toxic and easier to clean, with fewer volatile organic compounds (VOCs).

Can You Use Exterior Paint Indoors?

Technically, yes — but it’s not recommended. Here’s why:

1. Toxic Fumes

Exterior paint has a higher level of VOCs. These chemicals can linger in indoor spaces, potentially causing headaches, nausea, and respiratory issues, especially in poorly ventilated areas.

2. Odor

The strong smell of exterior paint can be overwhelming indoors and take days (or even weeks) to dissipate.

3. Overbuilt Durability

While durability sounds good, exterior paint's tough finish can be excessive for indoor surfaces, sometimes leading to cracking or peeling over time in a controlled indoor climate.

4. Finish and Appearance

Exterior paints tend to dry with a different sheen and texture. You might not get the refined, smooth finish that high-quality interior paints provide.

When Is It Okay to Use Exterior Paint Indoors?

There are rare instances where it might be acceptable:

• Garage interiors or sheds that aren’t climate-controlled
• Basements with moisture issues (only with proper ventilation)

Still, even in these cases, many Painting companies near Roswell would advise using specialty interior paints designed for high-moisture areas instead.
