The amount of volatile organic compounds (VOCs) in the air depends on the type of paint used. Normal indoor VOC levels are about 50% higher than outdoor air, but during painting or stripping, these levels can rise to 500 to 1,000. It is important to stir paint before using it to maintain consistency. Most paints last one to two years in an open can, while latex paints can last an average of 10 years in an unopened can. Oil-based paint lasts longer.
The effect of paint fumes can vary based on factors such as the amount of chemical in the indoor air, the length of time a person is exposed, and a person’s age, pre-existing conditions. Consumer Reports provides information on when leftover paint is past its prime, safe disposal methods, and which interior paints are at the top of our tests.
Unopened cans of paint will last longer than opened or partially used cans. However, no modern paints will off gas for more than a few weeks. Even older paints that have been used for years may spoil faster than they should.

How long to air out a room after painting?
Water-based paints take four hours to dry, while oil-based ones require a full day with open windows for ventilation. If you have allergies or respiratory issues, it’s okay to wait a couple of days for the paint to fully cure before sleeping in the room. Exposure to VOC fumes can lead to asthma attacks, respiratory issues, liver, kidney, and central nervous system damage. It’s also important to consider the risks for children, pets, and older adults, who are more susceptible to paint fumes. Allow the room to air out for two or three days before allowing them to sleep.
How long does it take paint fumes to go away?
The duration of the olfactory effects of fresh paint can vary considerably, with the dissipation of odours taking up to a week to occur. This is dependent on a number of factors, including the potency of the paint, the quantity used, and the dimensions of the room in question. Due to its potent odor neutralizing properties, vinegar is a popular deodorizing agent. It effectively inhibits the propagation of odor molecules.
The olfactory effects of freshly applied paint can persist for approximately 24 hours until the paint has fully dried. It is therefore advisable that individuals who are pregnant should avoid exposure to paint fumes until the paint has completely dried.
How long does it take for painted walls to stop smelling?
Paint odors can be a significant issue in newly renovated spaces, especially when the paint is fresh. To get rid of these odors, it is recommended to wait at least three days before moving back into the room to allow for filtration and reduce the initial toxic fumes. However, paint odors can linger for up to four months as the paint fully cures, releasing Volatile Organic Compounds (VOCs) into the air. These VOCs can cause headaches, dizziness, nausea, and respiratory irritation.
Toxic paint fumes on walls and ceilings can last from 14 to 24 weeks, depending on the amount of ventilation present in a room. Less ventilation can keep the bad smell of paint and its toxic fumes around longer, while more ventilation through ceiling fans, open windows, air filtration, and air purifiers can help remove the smell and filter away harmful VOCs that can linger even after the smell is gone.
Indoor air quality plays a crucial role in getting rid of paint smell and toxic VOCs quickly. By using natural or mechanical ventilation, harmful airborne contaminants are pushed out of an indoor space and replaced with fresh, clean air. Proper mitigation can help prevent the lingering odors from affecting the overall health and comfort of the living space.
How long do VOCs stay in air?
VOCs from products like paint and particle board dissipate over time as they vaporize. Paint dissipates quickly, with most offgassing occurring within 6 months. Other sources, like particle board, may continue to offgas for 20 years or more. If you have high concentrations of VOCs in your home, use a sealer or air purifiers to minimize their presence. Shop for zero-VOC and low-VOC stains, strippers, calks, and adhesives.
Can you sleep in a room that smells of paint?
Breathing paint fumes while sleeping can cause harmful effects on people of all ages, especially babies, young children, and pregnant women. The primary effects include eye, nose, throat, headaches, nausea, liver, kidney, central nervous system damage, and cancer. However, it’s unlikely that you’ll be exposed to enough VOCs when painting your home, and only high levels can cause these life-altering effects. Cancer caused directly by VOCs has only been observed in animal studies, but researchers believe humans could develop cancer after long-term exposure.
How to eliminate oil-based paint fumes?
To eliminate paint smell, follow these simple steps:
- Keep the room well-ventilated by opening windows and doors, using fans and air purifiers to improve ventilation.
- Maintain a cool indoor temperature after painting to reduce the potency of paint fumes. Turn on an air conditioner or let in a cool breeze to lower the temperature and reduce the scent intensity.
- Use baking soda to absorb paint smells, allowing you to use your space sooner. Leave it in the room for several days and replace it regularly to ensure continued odor absorption.
Can you sleep in a room with oil-based paint?
To ensure a safe painting process, research the drying times and fume levels of water-based and oil-based paints. Wait about four hours for water-based paint to dry and 24 hours for oil-based paint. Allow room air-out before moving occupants back in. If a baby will sleep in the room, allow extra time to air out. Sleep in another room for two or three days before bringing them back. As paint dries, ensure the room is well-ventilated by opening windows, keeping fans running, and maintaining good circulation.
How long are oil-based paint fumes harmful?
Paint fumes can be harmful if not handled properly. It is best to wait up to three days before using the painted room, as the paints are dry and the odor has subsided. Paint fumes are caused by VOCs, chemical additives that keep paint in its liquid state. Once the paint is applied and begins to dry, the gases and odors evaporate and disappear. It is essential to follow paint can instructions or consult the Safety Data Sheet for the product.
How long does interior paint offgas?
The pungent odor of paint is attributed to the evaporation of volatile organic compounds (VOCs), which may dissipate within days but can persist for months, as evidenced by studies conducted by the United States Environmental Protection Agency (US EPA).
How long to air out a house after painting?
Water-based paints take four hours to dry, while oil-based ones require a full day with open windows for ventilation. If you have allergies or respiratory issues, it’s okay to wait a couple of days for the paint to fully cure before sleeping in the room. Exposure to VOC fumes can lead to asthma attacks, respiratory issues, liver, kidney, and central nervous system damage. It’s also important to consider the risks for children, pets, and older adults, who are more susceptible to paint fumes. Allow the room to air out for two or three days before allowing them to sleep.
Is it OK to sleep in a room with paint fumes?
VOCs are harmful gases that are released into the air by various products or processes. Massachusetts has VOC Laws, which limit VOCs in paint products, primers, bonding agents, and repair products. Homeowners in Massachusetts should follow these regulations, as any paint sold in the local area should. However, it is possible to live with fewer VOCs by using low VOC, zero VOC, or oil-based paints. Massachusetts’ regulations apply to paint sold in various areas, including Arlington, Auburndale, Belmont, Boston, Brookline, Cambridge, Chestnut Hill, Jamaica Plain, and Jamaica Plain.
