Saving money on reusing paint may seem like a resourceful choice, but not all paint types are created equal. Exterior paints are formulated differently than interior paints because they are exposed to different elements. Interior paints see more scuffs, less sunlight, and higher dust content. Although it may save you money, using exterior paint indoors can be dangerous, and result in higher spending in the long run.
In this blog, we will explore the different properties of exterior and interior paint and why you should not use the opposite paint for the opposite project.
What Makes Interior And Exterior Paint Different?
There are many things that make interior and exterior paint different from one another. Chemical makeup, coloring, and curing time are just a few. Some of the most important differences are the VOCs that are released during the painting process. Volatile Organic Compounds, VOCs can cause health issues when confined to an interior space.
Exterior and interior paint also have varying curing times and curing properties. Exterior paints need sunlight to help them cure properly, or else they can take days to properly cure. Interior paints rely on air circulation and humidity levels to help them dry faster.
Here are some additional differences between the two paints:
- Interior paints don’t hold up against high UV rays
- Interior paints resist staining
- Exterior paints are made to withstand weather
- Exterior paint comes in fewer colors
Exterior Paint Takes Longer To Cure
As previously mentioned, exterior paint needs UV rays in order to cure properly. This is one of the main reasons that it is not recommended to use exterior paint indoors. When paint is not properly cured, it is more prone to scratching, peeling, discoloration, etc. While the paint will eventually cure inside, it will take much longer and you will not be able to use the space during this time.
Using Exterior Paint Inside Your Home Can Be Hazardous To Your Health
Because of the VOCs and the longer curing time, toxins can be released into your home that otherwise would not be with interior paint. The toxins and chemicals in exterior paint can cause issues such as:
- Headaches
- Dizziness
- Nausea
- Eye, nose, and throat irritation
- Loss of coordination
- Liver damage
- Kidney and nervous system malfunction
When utilizing paint in an enclosed space or close quarters, wearing proper protective equipment like a face mask or eye covering will help prevent health issues. Even with proper ventilation and PPE, using exterior paint inside is extremely risky.
Exterior Paint Won’t Hold Up To Interior Wear And Tear
It may seem odd that exterior paint is known to be durable, but won’t hold up to interior damages, but it is the truth. Exterior paint is built to withstand UV wear, weather, and pests and not dents, scratches, oils from fingers, etc. These paints will not hold up well to humidity during cooking, pet dander, and kids as well as interior paints. Using exterior paint indoors will require you to repaint your home more frequently because of damages.
Should You Use Interior Paint Outdoors?
The risks of using interior paint outside are far less than using exterior paint indoors, but that doesn’t mean it is the smartest idea. Indoor paint doesn’t give off VOCs that can damage your health and can still cure properly outside. However, interior paint will not be able to hold up well against heavy rain, snowfall, high heat, or pest infestations. Using interior paint outdoors will increase the frequency with which you need to touch up or repair the exterior of your home.
