Polyurethane is a common choice for finishing wood flooring and furniture, providing a hard, clear coating that safeguards against moisture and scratches. However, polyurethane’s drawback is its strong odor during application and drying.
This odor is primarily due to VOCs and other chemicals present in polyurethane.
If you’re looking for ways to eliminate the smell of polyurethane, I’m here to guide you through the exact steps!
7 Methods to Eliminate The Polyurethane Smell In Your House
Dealing with the strong odor of polyurethane can be challenging, but several effective methods exist to reduce and eliminate this smell.
1) Open Windows for Ventilation
The simplest and most effective way to start is by opening your windows. This creates cross-ventilation, which helps to dilute and disperse the polyurethane fumes. Fresh air circulation is key in reducing the intensity of the odor. *Especially important during the application process.
2) Use of Fans
Enhance air circulation by using fans. Place box fans in windows to push out the indoor air and bring in fresh air. Ceiling fans can also help circulate air within the room. The goal is to keep the air moving, which helps in clearing out the smell faster.
3) Air Purifier
An air purifier, especially one with a HEPA filter, can be very effective. These devices filter out tiny particles in the air, including the chemicals causing the odor. Place the air purifier in the room where the polyurethane was applied for best results.
4) Activated Charcoal
Activated charcoal is known for its ability to absorb odors. Place bowls of activated charcoal around the room. It works by trapping the odor-causing particles from the air, thus reducing the smell.
5) Onion and Lemon Slices
This traditional method involves placing bowls of water with slices of onion or lemon around the room. These natural ingredients can help neutralize and absorb the polyurethane smell. It’s a simple yet surprisingly effective approach.
6) Relocating Furniture
If you’ve applied polyurethane to furniture, consider moving it to a well-ventilated space like a garage. This prevents the smell from permeating your living areas and allows the furniture to off-gas more effectively.
7) Using Odor Eaters like Distilled White Vinegar and Baking Soda
Common household items like distilled white vinegar and baking soda are excellent at absorbing odors. Place bowls of vinegar or sprinkle baking soda in the affected area. These substances work by neutralizing the odor, making your space more pleasant.
Additional Tips and Tricks
Alongside the primary methods for eliminating polyurethane odor, there are a few additional tips and tricks that can further aid in speeding up the odor-removal process:
Using Specific Products
- Vaporsorb: This is a specialized product designed to target and neutralize chemical odors like those from polyurethane. Placing Vaporsorb in the affected area can help absorb and eliminate the lingering smell more effectively.
- Commercial Odor Neutralizers: There are various commercial products available that are formulated to neutralize strong odors. These can be sprayed or placed in the room where the polyurethane was applied.
Implementing Useful Techniques
- Heating the Room: A mild temperature increase can speed up polyurethane drying, reducing odor duration. Ensure not to overheat, as it might affect the curing process.
- Coffee Grounds: Place a bowl of coffee grounds in the room. Their natural odor-absorbing properties can help mask and absorb the polyurethane smell.
- Temporary Relocation: If feasible, stay elsewhere or move treated items to another location until the odor subsides, particularly for large projects or in living areas.
Frequently Asked Questions
How Long Does Polyurethane Smell and Off-Gassing Last?
The duration of polyurethane smell and off-gassing can vary, but typically, they can last from a few days to several weeks.
This depends on factors like the type of polyurethane used, ventilation, and room temperature. The peak period of off-gassing usually occurs within the first 24-48 hours after application, gradually decreasing thereafter. Ventilation is crucial as it can significantly reduce the smell and off-gassing duration.
What Should I Know About the Nature and Toxicity of Different Polyurethane Types?
Oil-based polyurethanes typically emit a stronger odor and contain higher levels of volatile organic compounds (VOCs), making them more toxic, especially during application and drying.
On the other hand, water-based polyurethanes generally have a lower odor and fewer VOCs, making them a safer option in terms of air quality.
Can I Stay in My House After Applying Polyurethane?
It’s advisable to stay in a different area, especially during the first 24-48 hours after application, due to the strong odor and potential health risks from the fumes.
Does Temperature Affect the Curing Time and Odor of Polyurethane?
Yes, higher temperatures can speed up the curing process, potentially reducing the duration of the odor. However, it’s important to avoid extreme temperatures that might affect the finish quality.
What Does Polyurethane Smell Like?
Polyurethane typically has a strong, chemical-like odor. It’s often described as pungent and can be similar to the smell of paint or varnish. The intensity of the smell can vary based on the type of polyurethane (water-based or oil-based) and the formulation of the product.
