The smell of paint is something everyone is familiar with, but have you ever wondered what exactly makes up that distinctive scent? Fresh paint has a noticeable odor that can vary quite a bit between different types and brands.
If you’re looking to get a deep understanding of what’s behind the smells of paint, you’ve come to the right place.
In short: The smell of paint is caused by the solvents and binders used to create it. Oil-based paints tend to have stronger odors from solvents like mineral spirits, while water-based latex paints use milder glycol ethers as solvents.
Other factors like VOCs and drying process also affect paint odor.
Solvents Used in Different Paint Types
When it comes to the smell of paint, the solvents used in the paint play a significant role. Solvents are the liquids that are added to the paint to help it flow and evaporate, leaving behind a dry and solid coating.
Different types of paints use different solvents, which can greatly impact the smell of the paint.
Oil-based paints are known for their durability and smooth finish, but they also have a distinct odor. The solvents used in oil-based paints are typically derived from petroleum or mineral spirits. These solvents have a strong smell that is often described as pungent or chemical-like.
The odor of oil-based paints can linger for quite some time, so it is recommended to work in a well-ventilated area when using these paints.
Latex paints, also known as water-based paints, are a popular choice for both interior and exterior applications. The solvents used in latex paints are primarily water and small amounts of other chemicals. As a result, latex paints have a much milder odor compared to oil-based paints.
The smell of latex paint is often described as being less harsh and more “paint-like” in nature. Additionally, latex paints tend to dry faster and have lower VOC (volatile organic compounds) emissions, making them a more environmentally friendly option.
Other Paint Types
There are also other types of paints that use different solvents. For example, acrylic paints use water as a solvent and have a similar odor to latex paints. On the other hand, enamel paints use solvents like acetone or toluene, which can have a strong and somewhat sweet smell.
It’s important to note that the odor of these paints can vary depending on the brand and specific formulation.

VOCs and Their Impact on Paint Smell
When it comes to the smell of paint, one of the key factors contributing to its odor is the presence of volatile organic compounds (VOCs). VOCs are chemicals that easily evaporate at room temperature, releasing gases into the air.
These compounds can have a significant impact on indoor air quality and human health.
What are VOCs?
VOCs are a diverse group of chemicals that are commonly found in many household products, including paints, varnishes, and solvents. They are released into the air during use and while the paint is drying. The strong smell associated with fresh paint is often attributed to these VOC emissions.
Exposure to high levels of VOCs can cause a range of health problems, including eye, nose, and throat irritation, headaches, dizziness, and even damage to the liver, kidney, and central nervous system. Long-term exposure to VOCs has also been linked to more serious conditions such as cancer.
VOCs in Oil-Based vs Latex Paints
Oil-based paints generally contain higher levels of VOCs compared to latex paints. This is because oil-based paints use solvents such as mineral spirits or turpentine, which have higher VOC content. These solvents help to dissolve the paint’s pigments and binders, but they also contribute to the strong odor.
On the other hand, latex paints contain water as a solvent, resulting in lower VOC levels. This makes them a popular choice for those who are sensitive to strong odors or concerned about indoor air quality.
However, it’s worth noting that even low VOC latex paints can still emit some odors during the drying process.
Low VOC and Zero VOC Paint Options
In recent years, there has been a growing demand for low VOC and zero VOC paint options. These paints are formulated with reduced levels of VOCs or contain no VOCs at all. They are designed to minimize the impact on indoor air quality and reduce the associated health risks.
Low VOC paints typically have VOC levels below the regulatory standards set by organizations such as the Environmental Protection Agency (EPA). Zero VOC paints, on the other hand, contain no VOCs or have trace amounts that are negligible.
These options are great for those seeking alternatives that are environmentally friendly and have a minimal odor.
It’s important to note that while low VOC and zero VOC paints may have reduced odor compared to traditional paints, they may still emit a slight smell during application and drying. Proper ventilation is essential to ensure adequate air circulation and to help dissipate any residual odors.

Factors that Influence Paint Odor
Paint odor can vary depending on several factors. Understanding these factors can help you choose the right paint for your needs and minimize any unpleasant smells. Here are some key factors that influence paint odor:
The type and amount of chemicals used in paint formulations can greatly impact the odor. Some paint ingredients, such as volatile organic compounds (VOCs), can release strong odors as they evaporate. VOCs are commonly found in oil-based paints and can contribute to the “paint smell” that many people are familiar with.
However, modern paint formulations have significantly reduced VOC levels, resulting in lower odor paints.
Paint Drying Process
The way paint dries also plays a role in the odor it emits. Water-based paints, for example, tend to have a milder smell compared to oil-based paints. This is because water-based paints dry through a process called coalescence, where water evaporates and the paint particles fuse together.
On the other hand, oil-based paints dry through oxidation, which can release stronger odors as the paint cures.
Primer vs Finish Paint
The type of paint you use can impact the odor as well. Primers are typically designed to have a lower odor compared to finish paints. This is because primers are formulated to provide an undercoat and seal the surface, often containing fewer VOCs.
Finish paints, on the other hand, are meant to provide the final color and protection, and may have a slightly stronger smell.
Temperature and Humidity
The environment in which you paint can also affect the odor. Higher temperatures and humidity levels can accelerate the evaporation of volatile compounds, resulting in a stronger smell. It’s recommended to paint in well-ventilated areas and to control the temperature and humidity levels to minimize any unpleasant odors.
Age and Storage
The age and storage conditions of paint can impact its odor. Paint that has been stored for a long time or exposed to extreme temperatures may develop a stronger smell. It’s important to properly store paint in a cool, dry place and use it within its recommended shelf life to ensure the best odor quality.
Colorants and Tinting
Adding colorants or tinting to paint can also contribute to its odor. Some colorants may have their own distinct smell, which can mix with the paint’s natural odor. However, the odor from colorants is usually minimal and not a significant factor in the overall paint smell.
Understanding these factors can help you choose the right paint for your project and minimize any unwanted odors. Remember to follow proper ventilation and safety guidelines when working with paint, and always consult the paint manufacturer’s instructions for specific odor-related information.
Tips for Dealing With Paint Odors
Choosing Low-Odor Paints
When selecting paint for your next project, consider choosing low-odor paints. These paints are specifically formulated to emit fewer volatile organic compounds (VOCs) that contribute to strong paint odors.
Look for paints that are labeled as low-VOC or zero-VOC, as these options have significantly reduced levels of harmful chemicals. Many reputable paint brands offer these environmentally friendly options, making it easier than ever to find a low-odor paint that suits your needs.
For more information on low-odor paints, you can visit the website of the Environmental Protection Agency (EPA), which provides detailed information on the impact of VOCs on indoor air quality.
Ensuring proper ventilation is crucial when dealing with paint odors. Opening windows and using fans can help to circulate fresh air into the room and dissipate the smell of paint faster. If possible, it’s also a good idea to paint on days when the weather allows for open windows and good airflow.
This will help to minimize the concentration of paint fumes in the air and make the environment more comfortable for both you and anyone else in the vicinity.
One effective way to prevent paint odors from permeating your space is to properly seal paint containers when they are not in use. Make sure the lids are tightly secured to prevent any lingering odors from escaping.
Additionally, consider transferring any leftover paint to smaller containers to minimize the amount of air that comes into contact with the paint. This can help to preserve the quality of the paint and reduce the intensity of the odor.
Activated charcoal is known for its ability to absorb and neutralize odors. Placing bowls of activated charcoal near the painted area can help to reduce the paint smell. The charcoal works by trapping the volatile compounds responsible for the odor, effectively minimizing their presence in the air.
You can find activated charcoal at most home improvement stores or online retailers.
Ionizers and Ozone Generators
Ionizers and ozone generators are devices that can help to eliminate paint odors from the air. Ionizers release negatively charged ions that attach to positively charged particles in the air, causing them to fall and reducing the paint smell.
Ozone generators, on the other hand, produce ozone molecules that react with the volatile compounds in the air, neutralizing them and eliminating the odor. It’s important to note that ozone generators should only be used in unoccupied spaces, as ozone can be harmful to humans and pets in high concentrations.
Baking Soda and Vinegar
Baking soda and vinegar are common household items that can also be used to combat paint odors. Placing bowls of baking soda or vinegar in the painted area can help to absorb and neutralize the smell. Both substances have natural deodorizing properties and can be effective in reducing the intensity of paint odors.
Remember to replace the baking soda or vinegar regularly to maintain their odor-absorbing capabilities.
By following these tips, you can effectively deal with paint odors and create a more pleasant environment during and after your painting projects.
The Diversity of Paint Scents
When it comes to paint, the smell can vary greatly depending on the type and formulation of the paint. From old oil-based paints to modern latex options, each type of paint has its own unique scent that can range from pleasant to pungent.
New and Old Oil-Based Paint
Older oil-based paints are known for their strong and distinctive smell. The odor is often described as a mix of chemicals and solvents, with a hint of sweetness. This type of paint odor can linger for days or even weeks after application.
However, advancements in technology have led to the development of low odor and low VOC (volatile organic compound) oil-based paints, which have significantly reduced the strong smell associated with traditional oil-based paints.
These newer formulations still have a slight odor, but it is much milder compared to their older counterparts.
Latex Paint Variations
Latex paints, which are water-based, have a much milder scent compared to oil-based paints. The smell is often described as a “clean” or “fresh” scent, with some variations having a faint chemical-like odor.
This type of paint is commonly used for interior walls and is preferred by many due to its low odor and easy cleanup with water. Some latex paints are also formulated to be low VOC, further reducing any potential odor.
Primers, which are used as a base coat before applying paint, can also have distinct smells. The smell of primer can vary depending on the type of primer being used. For example, oil-based primers tend to have a stronger smell similar to oil-based paints, while water-based primers have a milder scent similar to latex paints.
When using primers, it’s important to ensure proper ventilation to minimize any odors.
Specialty coatings, such as enamel paints or epoxy coatings, can have their own unique scents. Enamel paints often have a slightly sweet smell, while epoxy coatings can have an industrial or chemical-like odor.
These specialty coatings are typically used for specific applications, such as high-traffic areas or surfaces that require extra durability. It’s important to follow the manufacturer’s instructions when using specialty coatings to ensure proper ventilation and minimize any strong odors.
The smell that wafts off a can of fresh paint comes from a complex blend of ingredients that varies based on the type of paint. Oil-based enamels have the strongest odor thanks to solvents like mineral spirits, while latex paints use more mild solvents.
VOCs off-gas as paint dries also contribute to odor. Knowing the source of paint smells can help you minimize unpleasant odors. With the right preparations and low-VOC products, painting doesn’t have to be nose-wrinkling endeavor.
The rich diversity of paint scents may be puzzling, but a little knowledge goes a long way in decoding exactly what makes wet paint smell the way it does.
