Is It Possible To Paint An External Interior?

Exterior paint can be used indoors, but it is generally not recommended due to potential hazards. For interior projects, it is best to invest in a can of interior paint with safe ingredients for use indoors. While exterior paint can be used inside a garage, shed, workshop, or other outbuilding that isn’t used as a living space, it is only if you are looking to use up extra paint.

Exterior paint is usually quite durable and can withstand changing elements such as wind, rain, mildew, snow, and sunlight. It is durable enough to last between 7 to 10 years when properly applied. However, using exterior paint inside may expose yourself to potentially harmful chemicals that can emit unpleasant fumes indoors, and the finish may not be ideal for interior walls and trim.

The color application of exterior and interior paints is the same as the color application of interior paint, so while outdoor paint can technically be used inside, it doesn’t mean it should be used. The conditions of your covered patio will determine whether interior paint is suitable. If your patio is fully enclosed and protected from outdoor elements, interior paint would be fine.

In summary, while exterior paint can technically be used inside your home, it is not the best idea due to potential risks. The chemicals used for outdoor use can emit unpleasant fumes indoors, and the finish may not be ideal for interior walls and trim. It is better to keep exterior paint outside, where it belongs, and avoid using it inside.

What will happen if I use exterior paint inside?

Exterior paint contains volatile organic compounds (VOCs) and additives designed to last in harsh outdoor environments, which can negatively affect indoor air quality and health. These chemicals dissipate harmlessly when applied outside but can deteriorate more quickly when used indoors. The ingredients that keep exterior paint mildew-free outdoors can cause odors and allergic reactions when used in confined spaces. If you accidentally paint interior walls with exterior paint, you can prime them and repaint them with proper interior paint.

When selecting paint for your home, consider factors like color, finish, and VOC levels to create a beautiful, healthy, and safe space for your family. Remember, the goal is to create a beautiful, healthy, and safe space for your family.

What is the difference between interior paint and exterior 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.

Is exterior paint toxic after it dries?

Exterior acrylic paint contains high levels of volatile organic compounds (VOCs), which can cause ozone air pollution and cause breathing issues for allergy sufferers. It may also release harmful toxins even after drying. The additives used to make exterior paint durable outdoors are not suitable for indoor use due to its outdoor nature. Additionally, exterior paint is more susceptible to deterioration and scratches when used indoors than interior paint. Therefore, it is crucial to choose paint that is safe and environmentally friendly.

Is all exterior paint breathable?

Masonry paint is not breathable, as anything made with plastic is not breathable. Old houses need to breathe, and sloping plastic onto an old building can cause moisture retention in the building fabric, leading to peeling and flaking of the masonry paint. This is because water vapor pressure pushes the paint off the wall, acting like bubble gum. When a bubble grows, it bursts and pops, causing the paint to pop and blister as moisture finally gets out.

Sandtex masonry paint is the worst culprit, as it forms thick layers over years of painting an old house, eventually forming a thick plastic sheet. When removed, the sopping wet wall behind will gradually dry out. It has taken 18 months for old solid walled houses with Sandtex masonry paint to dry out when the Sandtex was removed. It is advisable to steer clear of any masonry paint, as it is not breathable and can cause significant damage to the building.

Why is exterior paint not good for interior?

The durability and weatherproof properties of exterior paints are achieved through the use of volatile organic compounds (VOCs), which are hazardous chemicals. The introduction of these volatile organic compounds (VOCs) into indoor environments may present health risks, particularly when the paint is in a wet state. Exposure to these compounds is significant both during the drying period and subsequently, as the paint continues to emit VOCs.

Can I use weathershield paint indoors?

Exterior paint, on the other hand, may be more harmful due to its inability to dissipate properly in enclosed spaces. Additionally, interior paint is thinner, requiring more coats and longer drying times than exterior paint, making it more difficult to cover surfaces and achieve opaque colors.

How long does exterior paint take to Offgas?

VOCs from paint typically release within six months after application, but can last longer or come from sources like particle board that off-gas for up to 20 years. Pregnant women should avoid exposure to paint fumes due to their potential health risks. If painting is necessary, use zero VOC paint, especially for interiors. To ensure good quality paint, choose paint that is environmentally friendly and safe for home use.
