Exterior paint can be used indoors, but it is generally discouraged due to higher VOC levels, strong odors, and suboptimal performance. It is best to opt for interior paint tailored for indoor environments to ensure safety and aesthetic appeal. Exterior paint may contain additives for UV protection and flexibility to endure fluctuating temperatures, raising concerns when used indoors.
When considering whether exterior paint can be used indoors or vice versa, it is important to choose a low-VOC or zero-VOC formula to minimize indoor air pollution. The composition of exterior paint, which includes various additives for UV protection and flexibility to endure fluctuating temperatures, raises concerns when used indoors.
Exterior paints usually contain latex, binders, and additives that increase the durability and flexibility of the paint, so it doesn’t buckle, crack, or fade despite being exposed to the elements. However, it depends on the conditions of your covered patio. If it is fully enclosed and protected from any outdoor elements, interior paint would be just fine. However, if your covered patio is not fully enclosed and protected from any outdoor elements, exterior paint would be just fine.
In summary, while exterior paint can technically be used inside your home due to its durability and fade resistance, it is not recommended due to the harmful chemicals released into the air. Outdoor paint contains chemicals not designed or intended for interior use, which can cause irritation and allergic reactions if used in areas not suitable for indoor use. Interior paints are made for washability and durability, while exterior paints are designed to hold up to UV rays and other elements.
In conclusion, while exterior paint can technically be used indoors, it is not recommended due to the potential risks and issues associated with using it indoors.

Exterior paints have a softer binding resin that resists fading, peeling, and chipping, while interior paints have a more rigid binding resin that reduces smearing and scuffing. This allows for a more versatile and durable paint solution for both indoor and outdoor use.
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.
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.
Can I use same paint interior and exterior?
The levels of volatile organic compounds (VOCs) in interior and exterior paints differ. Interior paint has a lower VOC level, making it unsafe to use inside. 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.
Is it okay to use exterior paint indoors?
The use of indoor exterior paint has been linked to adverse health effects and potential risks to family safety. It is advisable to ensure that fumes are not inhaled. The cost of exterior paints is typically higher due to the inclusion of additional ingredients that enhance durability, moisture resistance, and color fading resistance. These ingredients are included in order to enhance the durability and longevity of the paint.
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.
What happens if you paint the exterior of your house with interior paint?
Interior and exterior paints differ due to additives. Interior paints protect the interior from harsh weather conditions, while exterior paints contain weather-resistant chemicals and mildewcide to withstand heat, cold, snow, rainfall, and sun’s rays. Interior paint will eventually peel off walls and cause cracks. Concrete walls can expand and contract due to temperature fluctuations, so binder-based paint is better for concrete walls.
Low-cluster acrylics are used for patio and porch paints to resist UV damage, scuffing, fading, cracking, and concealing imperfections. Oil-based paints are better for exterior use due to their alkyd content, which resists dirt and temperature changes.
Can I paint indoor furniture with outdoor paint?
The text suggests that exterior paint would likely have a longer lifespan than interior paint due to its hardiness. However, the drying process differs, with exterior paint off-gasing more during drying. To avoid VOCs, it is recommended to paint it outside and let it cure under the shade. Exterior paint is designed to dry in the sun or open air, so it should be applied in a well-ventilated area or wear a P2 respirator. @MitchellMc can provide a more concrete answer.
What happens if I accidentally used exterior paint inside?
In the event of inadvertently utilising exterior paint within a domestic setting and subsequently seeking online guidance, there is no cause for concern. The solution is to apply a primer to the walls and then paint them with an interior paint that is free of the harmful chemicals found in exterior paints.
Why is exterior paint cheaper than interior paint?
There are two main types of paint: interior and exterior. Exterior paints are more expensive due to their added ingredients for toughness, moisture resistance, and UV color corrosion. Interior paints are more basic and less expensive. Paint finishes can range from flat to high-gloss, and the choice of finish doesn’t affect the cost. The four typical finishes are Flat, Eggshell and Satin, Semi-Gloss, and Gloss.
Professional paint testers look for specific qualities in paints before they are available for purchase. Before being available for purchase, paints undergo rigorous testing to ensure they meet the necessary standards.
Can you paint indoor wood with outdoor paint?
Exterior paints have higher volatile organic compound (VOC) levels, which can cause fumes indoors. To avoid this, opt for low-VOC or no-VOC paints with minimal chemical smell. Exterior paints come in various sheens, with flat or eggshell paints being ideal for indoor use as they hide imperfections and are washable. Glossier paints like satin or semi-gloss may appear too shiny and show surface flaws. Exterior paint’s durability, which can withstand weathering, may be a factor in indoor use.
