Selecting the right paint for your room can be extremely challenging. What if the color that you like is found in the “exterior paint” section? Is it okay to use exterior paint for your interior project? Although it may not seem like a big deal to use outdoor paint on your project inside your home, there are a few reasons why this may not be the best idea.
The Difference Between Exterior and Interior Paint
Although interior and exterior paints may seem like the same thing, there are many differences between the two. The way that they are engineered means that they have the ability to produce entirely different results from one another. Key differences between the two include the additives, the pigments, and the binding resins that are used.
Exterior Paints
Exterior paints do not contain rigid binding resins. This allows them to extend and contrast whenever they are exposed to outdoor temperature changes. They are also designed to withstand moisture and harsh weather conditions. As such, they are highly water-resistant and often contain additives that are designed to block the ultraviolet rays of the sun.
Interior Paints
Like exterior paints, interior paints are designed to be durable. However, they are designed to withstand anything your family can throw at them. As a result, these paints tend to withstand the impact of bumps and scuffs and are also scratch-resistant in some cases.
These paints are designed with specific additives that decrease drying time and ensure the pigment is distributed evenly. Interior paints are also designed to resist yellowing, fading, and staining, ensuring you can enjoy the color longer.
Why You Should Not Use Exterior Paint Inside Your Home
Exterior paints may seem like a durable and reliable option, but it can be quite dangerous to use them indoors. These paints are designed to sit out in the elements. As a result, they tend to have more harmful chemicals inside them. These paints include volatile organic compounds, which can harm your health. Some common VOCs that these paints contain include:
- Toluene
- Methylene chloride
- Formaldehyde
- Benzene
- 1,3-butadiene
- Xylene
- Tetrachloroethylene
- Ethylene glycol
As these paints dry, they give off gases and release volatile organic compounds into the air. Breathing these in can be hazardous and may trigger several side effects. Some of the problems you may experience due to exposure include:
- Nausea
- Headaches
- Irritation of the nose, eyes, and throat
- Damage to the kidneys
- Loss of coordination
Unfortunately, if you use acrylic exterior paint, these harmful chemicals may be released well after it dries. Although exterior paints may have the perfect color for your project, it is not worth the risk to use them inside.
