The Reasons Behind Not Using Outside Paint Indoors?

Interior paint is not hazardous to health but should not be used indoors due to its chemical composition, which can be harmful to humans. Exterior paint is designed to last for years and is incompatible with indoor spaces, containing more volatile organic compounds (VOCs). The primary reason to avoid using exterior paint inside is health concerns and the potential for unintended long-term effects.

Exterior paint is not durable enough to withstand the elements, as it contains far more VOCs (volatile organic compounds). It is also not resistant to the growth of mildew, making the paint weaker and causing cracking and flaking. Additionally, exterior paints are more expensive, thick, and may flatten out texture, smelling like paint in your house.

The additives needed to make exterior paint resilient outdoors are not intended for use inside, and if used inside poorly ventilated rooms, harmful gases will accumulate and pose health risks to occupants. The chemicals that make exterior paint durable for outdoor use can emit unpleasant fumes indoors, and the finish often isn’t ideal for interior walls and trim.

Efficiently cured exterior paint takes much longer than interior paint, leaving walls vulnerable to scratches. The ingredients in exterior paint give off high VOCs, which is the primary reason why you wouldn’t want to apply it indoors.

In conclusion, it is not recommended to use exterior paint on the interior of your home due to its chemical composition, potential health risks, and the potential for adverse health symptoms. It is essential to choose the appropriate paint for your home’s needs and consider the potential health risks associated with using exterior paint indoors.

Repairing this damage requires sanding the paint off the substrate, sealing with an outdoor primer, and repainting the entire area with the appropriate outdoor wall paint.

Why is exterior paint cheaper than interior paint?

Is there really a difference between interior and exterior paint?

Interior and exterior paints share the same components, including pigment, resin, solvents, and additives. Oil paint manufacturers use mineral spirits as a solvent, while latex paint manufacturers use water. The main difference lies in the binding resins used in interior paint. Exterior paint is softer, better able to resist fading, peeling, and chipping, while interior paint is more rigid, reducing smearing and scuffing. Interior paints offer a variety of finishes, from matte to high gloss, and can enhance natural light, making spaces appear larger and more welcoming.

They are more delicate but have their own volatile organic compounds (VOCs). Indoor paint typically has lower VOC concentrations, and some paints, like Real Milk Paint, have no VOCs. Water-soluble interior paints offer a more comprehensive selection of finishes than exterior paints.

What happens if I use exterior paint inside?

If you accidentally paint interior walls with exterior paint, you can prime them and repaint them with proper interior paint.
