Using interior paint outside may seem like a great idea to save money, but it’s important to understand the implications associated with this decision. Interior paint is formulated to perform well under specific conditions, which may not be the same as the outdoor elements. As a result, using interior paint outside could lead to a wide range of problems, including premature fading, cracking, and peeling.
The Difference between Interior and Exterior Paint
The main difference between interior and exterior paint is the amount of resin that is used in each type of paint. Exterior paint contains more resin, which creates a strong, durable finish that is able to withstand harsh weather conditions. Interior paint is formulated to be used in closed, temperature-controlled environments, so it does not contain as much resin. This makes interior paint more prone to cracking, fading, and peeling when exposed to extreme temperatures, direct sunlight, and other harsh elements.
The Risks of Using Interior Paint Outside
Using interior paint outside can create a number of problems. The paint may not adhere properly to the surface, leaving it vulnerable to cracking, fading, and peeling. In addition, the paint may not be able to withstand the harsh elements, leading to premature fading and chalking. Furthermore, the paint may not be able to block moisture, leading to the growth of mold or mildew. Finally, the paint may not be able to withstand extreme temperatures, leading to cracking or flaking.
Tips for Using Interior Paint Outside
If you decide to use interior paint outside, there are a few tips you should keep in mind:
- Make sure you use a paint that is specifically formulated for exterior use.
- Ensure the surface is clean and dry before painting.
- Apply a coat of primer before painting.
- Allow the primer to dry completely before painting.
- Use multiple coats of paint for better protection.
- Allow the paint to dry completely between coats.
- Apply a sealant after the paint has fully dried.
Using interior paint outside can be a cost-effective option, but it pays to understand the potential risks associated with this decision. If you decide to use interior paint outside, make sure you follow the tips outlined above to ensure the paint adheres properly and provides the necessary protection.
