how to get rid of polyurethane smell

Polyurethane is a popular finish for wood surfaces, known for its durability and protective qualities. However, one major drawback of using polyurethane is the strong odor it emits during and after application. This lingering smell can be quite unpleasant and may even pose health risks if not handled properly. In this comprehensive guide, we will explore various methods to effectively eliminate polyurethane smell, ensuring a safe and pleasant environment in your home.

Understanding Polyurethane and Its Odor

Polyurethane is a synthetic polymer used in a variety of applications, including coatings for furniture, floors, and other wooden items. The odor associated with polyurethane primarily comes from the solvents used in the formulation. These solvents are volatile organic compounds (VOCs) that can evaporate into the air, creating a strong smell that can linger for days or even weeks after application.

Why Does Polyurethane Smell?

The smell of polyurethane is mainly due to the presence of solvents and other chemicals that help in the application process. When the product dries, the solvents evaporate, leaving behind the polyurethane coating. The intensity of the odor can vary depending on the type of polyurethane used—oil-based polyurethanes typically have a stronger smell than water-based versions.

Health Risks Associated with Polyurethane Odor

Inhaling the fumes from polyurethane can lead to various health issues, especially for sensitive individuals. Short-term exposure can cause headaches, dizziness, and respiratory irritation, while long-term exposure may lead to more severe health problems. It is crucial to take appropriate measures to mitigate these risks and reduce the smell as quickly as possible.

Preparation Before Applying Polyurethane

Before diving into methods for removing polyurethane smell, it is essential to prepare the area properly to minimize the odor during application. Here are some steps to consider:

1. Choose the Right Type of Polyurethane

If you are planning to apply polyurethane, consider using a water-based variant instead of an oil-based one. Water-based polyurethanes have a lower VOC content and are less odorous, making them a better choice for indoor projects.

2. Ventilate the Area

Ensure that the workspace is well-ventilated before applying polyurethane. Open windows and doors to allow fresh air to circulate, and use fans to help disperse the fumes. Proper ventilation can significantly reduce the odor during the drying process.

3. Wear Protective Gear

Always wear a mask, gloves, and goggles when working with polyurethane. This will help protect you from inhaling harmful fumes and minimize skin contact with the chemicals.

Methods to Get Rid of Polyurethane Smell

Once you have applied polyurethane and are dealing with the lingering smell, there are several effective methods to eliminate it. Here are some tried-and-true strategies:

1. Increase Ventilation

The first and most effective way to reduce polyurethane smell is to increase ventilation in the area. Open windows and doors, and use fans to create cross-ventilation. This will help to dissipate the fumes more quickly.

2. Use Baking Soda

Baking soda is a natural odor absorber and can effectively neutralize the polyurethane smell. Place bowls of baking soda around the room, and leave them for several days to absorb the odors. You can also sprinkle baking soda on surfaces and vacuum it up after a few hours.

3. Activated Charcoal

Activated charcoal is another excellent odor absorber. Place bowls of activated charcoal in the affected area, and let them sit for a few days. The charcoal will absorb the VOCs and help to eliminate the smell.

4. Use Vinegar

Vinegar is known for its ability to neutralize odors. Fill bowls with white vinegar and place them around the room. The vinegar will absorb the polyurethane smell over time. Alternatively, you can mix vinegar with water and use it to wipe down surfaces.

5. Essential Oils

Essential oils, such as lavender, lemon, or eucalyptus, can help mask the smell of polyurethane. Add a few drops of essential oil to a diffuser or mix with water in a spray bottle and mist the area. This will not only help to cover the odor but also provide a pleasant aroma.

6. Air Purifiers

Investing in an air purifier with a HEPA filter can significantly improve air quality and reduce polyurethane smell. These purifiers can capture VOCs and other harmful particles, making the air safer to breathe.

7. Onions

Though it may sound unusual, onions can absorb odors. Cut a few onions in half and place them in bowls around the room. The onions will absorb the smell of polyurethane, but be prepared for a slight onion scent in return!

Cleaning Up After Polyurethane Application

After applying polyurethane and dealing with the smell, it’s essential to clean up any spills or tools used during the application process. Here are some tips for cleaning:

1. Clean Tools Immediately

Clean brushes, rollers, and other tools immediately after use to prevent the smell from lingering. Use mineral spirits or paint thinner for oil-based polyurethane, and soap and water for water-based options.

2. Dispose of Rags Properly

Rags soaked in polyurethane can be a fire hazard. Dispose of them in a sealed container, or soak them in water before disposal to prevent spontaneous combustion.

3. Wash Surfaces

If you notice any residue left behind from the application, clean the surfaces with a mixture of water and mild detergent. This will help to remove any lingering odor and residue.

Long-Term Solutions for Polyurethane Smell

If you find yourself frequently dealing with polyurethane smell, consider implementing long-term solutions to minimize the issue:

1. Choose Low-VOC Products

When selecting polyurethane or other finishes, look for low-VOC or zero-VOC options. These products are formulated to produce fewer odors and harmful emissions.

2. Regular Ventilation

Make it a habit to ventilate your home regularly, especially after completing any projects involving finishes or paints. This will help to keep indoor air fresh and reduce the buildup of odors.

3. Maintain Humidity Levels

Keeping humidity levels in check can help to reduce the intensity of odors. Use a dehumidifier if necessary to maintain optimal humidity levels in your home.

Conclusion

Getting rid of polyurethane smell can be a challenging task, but with the right strategies, it is entirely achievable. By increasing ventilation, using natural odor absorbers like baking soda and vinegar, and maintaining a clean environment, you can effectively eliminate the unpleasant odor associated with polyurethane. Remember to take precautions when applying polyurethane and opt for low-VOC options whenever possible to minimize future odor issues.
