Using interior paint on exterior surfaces is generally not recommended, but it can be a cost-effective and short-term fix for small, low-impact outdoor projects. However, using interior paint outside can lead to unsightly flaws such as cracking, blistering, bubbling, and eventually peeling off the surface. Interior paints may contain organic pigments for color, which can significantly fade if used outside. Mindeck suggests scraping or sanding the paint off the surface before starting over with proper exterior primer and paint.
The two most popular exterior paint types are oil-based and latex. If you have already used interior paint outdoors, there are a few steps you can take to remedy the situation:
- Remove Paint and Repaint. While it is not recommended to use interior paint outside, some people may still choose to do so. However, the paint job will not last very long since interior paint is not crafted to withstand outdoor elements such as wind, rain, and direct sunlight.
Interior paints are made for washability and durability, while exterior paints are made to hold up to UV rays and temperatures. To seal the coating and prevent future problems, apply an exterior paint over the existing interior paint. Concrete can expand and contract when it undergoes temperature fluctuations, so paint that contains a binder is good for concrete walls.
Conditioning can harm interior paint, so it is important to use exterior paint and a good primer. Interior paints are formulated differently than exterior paints, and they won’t hold up to the elements from the outdoors, so they may crack or peel off the surface.

What happens if I use interior paint outside?
Interior paint used on an exterior surface can cause aesthetic flaws due to its inability to withstand exterior elements, leading to cracking, blistering, bubbles, and peeling. It is not recommended to use interior paint on an exterior surface as it may not last long. 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.
This can be time-consuming and costly. If an accident occurs and indoor paint is used outdoors due to a wrong label, applying 1 or 2 coats of outdoor paint immediately after drying can save the paint.
What is the difference between house paint and porch paint?
Interior and exterior paints have distinct compositions, with exterior paints designed to withstand environmental conditions like UV rays and temperature fluctuations, while interior paints prioritize low VOC levels for indoor air quality and resistance to scuffs and stains. Exterior paints contain softer binding resins and additives for flexibility and UV resistance, while interior paints use rigid resins for durability and often feature lower VOCs for health safety.
Choosing the right type of paint is crucial, as using interior paint outdoors can lead to finishing issues like cracking and peeling, while using exterior paint indoors can pose health risks due to higher VOC content and inappropriate formulation for confined spaces. Understanding these differences is essential for maintaining the aesthetic and structural integrity of a painted surface and choosing the right product for the right place, whether you’re planning to refresh a single room or revamp the entire exterior of your home.
In conclusion, understanding the differences between interior and exterior paints is crucial for maintaining the aesthetic and structural integrity of a painted surface and choosing the right product for the right place.

Can you use interior paint on a deck?
Interior paint is not designed to withstand the effects of outdoor elements, such as wind, rain, and direct sunlight. This lack of durability can result in a number of issues, including color fading, peeling, bubbling, and cracking. The optimal exterior paint is a durable, water-based paint that can withstand harsh weather conditions. It is imperative to select a paint that is capable of withstanding these environmental factors and retaining its quality over time.
Is indoor paint waterproof?
Waterproof paint is typically used for exterior surfaces, such as wood or masonry, to withstand rainfall. However, interior paints are not waterproof, as bathrooms must endure high moisture levels, such as condensation. To ensure the longevity of the paint, it must be moisture resistant. Moisture resistant paints can come in various forms, such as primers or emulsions with added ingredients. Standard emulsions are used for painting walls and ceilings in bathrooms, but it is recommended to use a paint with more moisture resistance, especially if the bathroom has poor ventilation. Overall, there are various options available for waterproof paint for bathrooms, including emulsion paints designed for interior use.
Can I use interior paint on a covered porch?
Interior paint should not be used outside due to its inability to withstand outdoor elements like wind, rain, and direct sunlight. The paint job may experience color fading, peeling, bubbling, and cracking, wasting the hard work in just a year.

Can I paint my porch with regular paint?
Porch paint should be exterior-specific and durable, able to withstand frequent wear and tear and outdoor conditions. Concrete porch paint is recommended for its durability and resistance to harsh weather and traffic. After painting, wait 24 hours before walking on the surface to ensure it is dry.

Can I use interior paint on an exterior door?
Interior paint can be used outside for various reasons, such as cost-effectiveness, leftover paint, or temporary covering. However, it should not be used outside due to its different formula from exterior paint, which does not resist external weather conditions like snow, dirt, rain, and sunlight. Interior paint can be used on front doors, but it must be prepared, especially if the door is metal. If the door is protected with a glass door, the paint can be used on the exterior, but it may crack, fade, and chip.
If using interior paint for the exterior, one or two coats of exterior-grade clear coat sealer can be applied, but the adhering time may vary and the sealer cannot prevent fading. Additionally, warranty cannot be claimed if interior paint is used for exterior surfaces.
What is the difference between interior paint and exterior paint?

With this guide, you can make informed decisions for your next painting project, ensuring enduring and beautiful results.
How long will interior paint last on the exterior?
Interior paint outdoors may need repainting after a year or two, depending on the area’s exposure. Consider sealing it with weather-resistant sealer or waterproof paint at Walmart to help it withstand the elements. France’s new government is set to take a hardline stance on migration issues, aiming to significantly reduce the number of people entering and staying illegally in the country. President Emmanuel Macron appointed Prime Minister Michel Barnier, a veteran conservative from The Republicans party, to work with the divided legislature to end political turmoil.
The Barnier government, dominated by conservatives and centrists, does not have a majority in parliament, and efforts to pass new legislation are likely to be fought and potentially blocked. Ballot gathering, or ballot collecting, is a controversial practice where a voter completes an absentee ballot, places it in a sealed, signed envelope, and entrusts it to another person who then drops it off at a mail center or designated ballot drop-off location. Ballot gathering is legal in some form in 35 states. Conservative Christians were skeptical of mail-in ballots, but now they are gathering them in churches.
Can you seal indoor paint for outdoor use?
Contractor Jay Sanders warns that while interior paint can be primed, painted, and sealed, it will still peel, chip, and crack when exposed to the elements. To reduce the need for exterior paint, it is recommended to use high-quality external paint and prepare thoroughly. While it may be tempting to use leftover paint from interior redecorating, it is not a recommended method as it is not designed to do the job and may require more repainting due to the differences in formulation between interior and exterior paints. Therefore, it is a DIY and decorating faux pas.
