Expert opinion: Can you use interior paint for exterior surfaces? Insights from paint professionals

Can you use interior paint outside Paint professionals give their expert verdict

Furniture generally stays indoors, where it is sheltered from the elements and any potential damage caused by the sun, rain, or snow. But what about the exterior of your house? Can you use interior paint outside?

When we think of painting, we often think of peeling paint on the outside of homes, but it’s worth noting that not all paints are created equal. Some paints are specifically designed to withstand the outdoors, while others are meant for use indoors only.

To help you make the right decision, we spoke to paint professionals at Kazimierski Painting and Improovy, the latest newsletter for the painting industry. They shared their expert opinions on the topic and gave us some ideas on when it’s okay to use interior paint outside.

Can you use interior paint outside

When it comes to painting the exterior of your house, using interior paint may seem like a quick and easy solution. However, paint professionals advise against using interior paint for outdoor projects. Interior paints are not designed to withstand the harsh elements of the outdoors and may not provide the same level of durability as exterior paints.

Alex Kazimierski, a professional painter and owner of Improovy Painters in Chicago, emphasizes the importance of using the right type of paint for each specific application. “Interior paint is formulated to be used indoors, where it is not exposed to direct sunlight, rain, snow, and other weather conditions that can cause it to peel and fade,” says Kazimierski.

Using interior paint outside can lead to several problems. The paint may peel, crack, or blister when exposed to moisture, temperature fluctuations, and UV rays. It may also not adhere properly to the surface, resulting in a shorter lifespan and the need for frequent touch-ups.

One of the main differences between interior and exterior paint is the presence of additives in exterior paint that provide protection against weathering. These additives help the paint withstand extreme temperatures, moisture, and UV rays, ensuring that it maintains its color and finish over time.

Painting the exterior of your house is a significant investment, and using the right paint is crucial to ensure long-lasting results. While interior paint may be more affordable, it may end up costing you more in the long run due to the need for frequent repainting and repairs.

It’s worth consulting with a professional painting contractor who can guide you on selecting the right type of paint for your specific project. They will consider factors such as the climate in your area, the condition of the surface you’re painting, and any specific requirements or preferences you have.

In some cases, if a specific area of your exterior is sheltered or protected from direct sunlight and weather, using interior paint may be a viable option. For example, painting a covered porch or an area of the house that faces away from the sun might be a situation where using interior paint could work.

To make the most informed decision, it’s recommended to weigh the pros and cons of using interior paint outside and consult with a professional painter who can offer expert advice tailored to your specific needs.

In conclusion, while it may be tempting to use interior paint for exterior projects, it is generally not recommended by paint professionals. Exterior paints are specifically formulated to withstand the elements and provide long-lasting protection and durability. Investing in the right type of paint for your exterior will ensure a beautiful and lasting result.

Pros

Pros

Using interior paint outside has several benefits, but it’s important to consider the specific conditions and requirements before making a decision. Here are some pros of using interior paint outdoors:

  • Cost-effective: Interior paints are generally less expensive than exterior paints, so using them outside can help save money on your painting project.
  • Wide range of color options: Interior paint offers a wide variety of colors and finishes, allowing you to easily find the perfect shade for your exterior walls.
  • Easy to find: Interior paints are readily available at most hardware stores and paint retailers, making them easily accessible for any outdoor painting project.
  • Quick drying: Interior paint dries faster compared to exterior paint, which can be advantageous if you need to complete the painting project in a shorter time frame.
  • Great for sheltered areas: If the area you plan to paint is well-sheltered and not exposed to direct sunlight or harsh weather conditions, interior paint can withstand moderate outdoor use.

While these benefits make using interior paint outside seem like a viable option, it’s worth noting that there are also some drawbacks and considerations to keep in mind. Interior paint is not specifically formulated to withstand the elements and may not hold up as well as exterior paint over time. It’s also likely to peel and fade more quickly when exposed to direct sunlight and moisture.

However, if you’re looking to paint outdoor furniture or decorative pieces that are not exposed to the elements, using interior paint can be a good choice. It can also be a creative option for adding color to outdoor wall backdrops or creating custom designs on exterior surfaces.

It’s important to consult with a professional contractor or paint expert to determine if using interior paint outside is an appropriate option for your specific project. They can provide guidance on the best type of paint to use and offer insights on proper preparation and application techniques.

If you do decide to use interior paint outside, be sure to clean and prime the surface before painting to ensure proper adhesion and longevity. Applying a clear topcoat or sealant can also help protect the paint from the elements and make it last longer.

Overall, while interior paint can be fairly versatile and generally suitable for outdoor use in certain situations, it’s important to weigh the pros and cons and consider the specific conditions in which the paint will be exposed. Staying informed and seeking professional advice can help you make the best decision for your outdoor painting project.

Cons

1. Direct exposure to outdoor elements: Generally, interior paints are not designed to withstand the harsh conditions of the outdoors. The exterior of a house is exposed to direct sunlight, rain, snow, and temperature variations, which can cause the paint to fade, peel, or crack over time.

2. Less durable: Interior paints are formulated to resist wear and tear from everyday household activities, such as furniture moving and cleaning. However, they may not hold up as well when used outside, where they could be subjected to more intense use and exposure.

3. Inadequate protection: Exterior paints are specifically made to provide adequate protection to the underlying wall against moisture, UV radiation, and other environmental factors. Using interior paint outside may not provide the same level of protection, leading to potential damage to the wall and the overall structure of the house.

4. Limited color options: Interior paints come in a wide range of colors and finishes, allowing homeowners to create a variety of decorative effects. However, the color choices for exterior paints are more limited, as they need to withstand outdoor conditions and be compatible with the architectural style of the house.

5. Voided warranty: If you decide to use interior paint outside, you may void the warranty provided by the manufacturer. Most paint manufacturers offer separate warranties for interior and exterior paints, and using the wrong type of paint can negate any coverage in case of issues or paint failures.

6. Potential damage to furniture and surfaces: Exterior paints are formulated to be more resistant to stains, moisture, and other outdoor elements. Using interior paint outside may result in damage to furniture, surfaces, or other items that come into contact with the painted wall.

7. Higher maintenance requirements: Exterior paints are designed to require less frequent maintenance compared to interior paints. If you use interior paint outside, you may need to repaint more often to maintain the appearance and protection of the painted surface.

8. Reduced lifespan: Interior paints typically have a shorter lifespan than exterior paints when used outdoors. The paint may begin to deteriorate and peel much sooner than expected, requiring more frequent repainting, which can be time-consuming and costly.

9. Lack of expertise: Interior painters may not have the same level of expertise or knowledge when it comes to painting exteriors. Hiring a professional painter or contractor who specializes in exterior painting is generally a better choice to ensure that the job is done properly and lasts.

10. Aesthetics: Exterior paints are specifically formulated to provide a suitable backdrop for the overall look and style of the house. Using interior paint outside may not give you the desired aesthetic effect, as the color and finish may not be as suitable for the external appearance of the house.

11. Impact on property value: Using interior paint outside may have a negative impact on the value of your home. Prospective buyers may see it as a sign of poor maintenance or lack of attention to detail, potentially reducing the selling price or making it harder to sell.

12. Cost-effectiveness: While interior paints are generally less expensive than exterior paints, using interior paint outside may not be a cost-effective solution in the long run. Considering the additional maintenance and potential issues that may arise, it may be worth investing in exterior paints that are specifically formulated for outdoor use.

Overall, while it may be tempting to use interior paint outside to save money or take advantage of the latest color trends, it is generally not recommended. Using the right type of paint for the right purpose is important to ensure a long-lasting and durable finish that can withstand the outdoor elements.

Is there anything you can do to make interior paint last outside

When it comes to painting the exterior of your home, using interior paint may seem like a cost-saving option. However, paint professionals generally do not recommend using interior paint outside, as it is not designed to withstand the harsh outdoor conditions.

Interior paint, also known as emulsion paint, is specifically formulated for indoor use. It is designed to be applied to interior walls that are sheltered from direct sunlight, rain, and other outdoor elements. Interior paint is typically used to enhance the aesthetic appeal of the indoors, providing a vibrant and long-lasting color to the walls.

On the other hand, exterior paint is specially formulated to withstand the harshest outdoor conditions. It is designed to protect the exterior walls of homes and buildings from the sun’s UV rays, rain, snow, wind, and other environmental factors. Exterior paint is made to be more durable, weather-resistant, and fade-resistant compared to interior paint.

Using interior paint outside may result in several issues. Firstly, interior paint is likely to fade and peel quickly when exposed to the elements. The sun’s UV rays can cause the paint to fade and lose its color, while rain and moisture can make the paint peel and bubble. Additionally, interior paint may not adhere properly to exterior surfaces, leading to poor adhesion and premature paint failure.

If you are considering using interior paint on the exterior of your home, it may be worth consulting a paint professional or contractor for their expert opinion. They can provide you with the latest information and guidance on the best paint options for your specific project.

Alternatively, if you are looking for ideas to refresh your home’s exterior, there are other ways to improve its appearance without using interior paint. You can consider power washing the exterior walls, repairing any damaged areas, or adding new furniture and decor to create a new backdrop for your outdoor space.

In conclusion, while it may be tempting to use interior paint outside, it is generally not recommended. Interior paint is not designed to withstand the harsh outdoor conditions, and using it on exterior walls can lead to issues such as fading, peeling, and poor adhesion. It is best to use exterior paint, specifically formulated for outdoor use, to ensure a long-lasting and durable finish for your home.

Can you use emulsion outside

Using emulsion paint outside can be a bit tricky. Emulsion paints are typically designed for interior use and may not be able to withstand the harsh weather conditions and direct exposure to sunlight that outdoor spaces often experience.

Where you are using the emulsion paint and the specific conditions it will be exposed to can make a difference in whether you should go ahead with using it outside. If you are looking to paint an external wall or a piece of furniture that is in a sheltered area, such as a covered patio or porch, using emulsion paint may be worth considering.

Emulsion paints can provide a great backdrop for your outdoor space and give you the opportunity to experiment with different color schemes and ideas. However, it’s important to note that emulsion paints are generally not as durable or long-lasting as paints specifically formulated for exterior use. If you decide to use emulsion paint outside, you may need to reapply it more frequently, especially if the area is exposed to a lot of sunlight or moisture.

Before taking on any external painting project, it’s worth consulting with a professional painter or contractor who can advise on the best type of paint to use. They will be able to assess the specific conditions of your outdoor space and recommend the most suitable products.

Overall, using emulsion paint outside can be a viable option, but it’s important to consider the specific conditions and durability requirements of the area you are painting. If you’re unsure, it’s always a good idea to seek advice from professionals to ensure you achieve the best results.

What to do if you used interior paint outside accidentally

If you have accidentally used interior paint on the outside of your house, don’t panic! There are a few steps you can take to rectify the situation and ensure your exterior walls are properly protected.

1. Assess the damage

First, take a close look at the wall where the interior paint was applied. Has it been exposed to direct sunlight, rain, or extreme temperature changes? If so, there may be some peeling or fading, and the paint may not have adhered properly to the surface.

2. Consult a contractor

If your wall has been significantly affected, it’s a good idea to consult a professional contractor. They will be able to assess the extent of the damage and recommend the best course of action.

3. Remove the interior paint

If the damage is fairly minor and you think you can tackle it yourself, start by removing the interior paint from the outside wall. Use a paint scraper or a sander to gently strip away the peeling paint.

4. Prep the wall

Once the interior paint has been removed, it’s important to properly prepare the wall before applying an exterior paint. Clean the wall thoroughly to remove any dirt, grease, or loose particles. Fill any cracks or imperfections with an appropriate filler.

5. Choose the right paint

When selecting an exterior paint, make sure to choose a paint that is specifically formulated for external use. External paints are designed to withstand the harsh elements and provide long-lasting protection to the wall.

6. Prime and paint the wall

Apply a coat of primer to the prepared wall before painting. This will help the new paint adhere better and provide a more even finish. Once the primer is dry, apply several coats of exterior paint, following the manufacturer’s instructions.

7. Consider sheltered areas

If there are areas of the wall that are sheltered or receive less direct exposure to the elements, such as under an overhang or behind furniture, you may be able to get away with leaving the interior paint as a backdrop. However, keep in mind that the paint may still deteriorate over time.

8. Learn from the mistake

Accidentally using interior paint on the outside of your house can be a valuable learning experience. Take note of the paint type and make sure to double-check labels in the future, so you don’t make the same mistake again.

Final thoughts

While using interior paint outside can be a costly and time-consuming mistake, it is possible to rectify the situation with some effort. By following these steps and seeking professional help if needed, you can restore the appearance and protect the integrity of your exterior walls.
