Varnish made of polyurethane is undoubtedly one of the most beautiful and long-lasting finishes available.
However, the toxic vapors could negatively affect your household if you need to learn how to get rid of the smell of polyurethane in the finished area.
Isocyanates and volatile organic compounds are the building blocks of polyurethane.

How to Get Rid of the Strong Smell of Polyurethane
Turn the lights off and open the doors and windows to breathe fresh air or indoor air quality and avoid musty smell.
Turn on the fans, and keep an air purifier operating.
Sliced onions or lemons soaked in water and white vinegar should be used to absorb the stench.
Paper plates containing baking soda, activated charcoal, and fume-absorbent grains should be distributed at the appropriate locations.
How to Remove the Strong Odor of Polyurethane from Floors
It is likely most effective to adopt a combination of the following strategies; doing so will allow you to obtain results more quickly.
Throw open the windows and let some fresh air in.
Ventilation is always the first step that should be taken before, during, and after refinishing jobs. It is important to remember this.
To improve fresh air circulation in the musty room, open all the windows and doors.
The odor of polyurethane, which is nearly intolerable by itself, begins to dissipate as soon as it is exposed to fresh air.
Therefore, ensure you leave the air inlets open for the required time until the clean air has been restored within the house.
To remove polyurethane fumes from the hardwood floor, use ceiling fans and table fans or position a box fan within a window and allow it to run for as long as required.
This will assist in enhancing air circulation and removing stale, polluted air from space.
If you only need the box fan for a short period, such as for the one-time polyurethane project, you can rent it from a storage unit or another facility.
But if you would rather own it, then doing so would be a wise investment.
Maintain a filtering system for the air to remove harmful substances.
If you want to eliminate the smell of polyurethane in your wood flooring, consider investing in an air filtration system.
Then, put it to use in the area where polyurethane is still off-gassing by putting it in the room where it is happening and turning it on for as long as you need to to get clean air circulating there.
You have the option to either buy or rent one that has an activated charcoal or ozone filter.
The purifier will collect the polyurethane odor, then send it through a filter that decomposes the chemical components, and finally, the odor will be neutralized.
You may try Lampe Berger.
Burning a Lampe Berger is yet another effective method of removing hazardous gases.
After filling the glass container with 90% alcohol, adding a few drops of essential oil, lighting the wick, and allowing the mixture to burn for at least 20 minutes, we won’t be covering up the odor already there.
The open flame will consume the hazardous chemical compounds in the air without causing the air to catch fire.
After then, extinguish the flame and allow the smoke to disperse.
Within the next 20 minutes, you should notice that the hazardous vapors are beginning to dissipate.
However, maintain its operation for a more extended period until you reach a point where you are content with the aroma of the air circulating inside the building.
After some time, you can fill your interior area with perfume by using essential oils alone.
In a dish of water, onions or lemons can be found.
This common component is a reliable cure for removing the smell of polyurethane from the area.
Cut an onion in half lengthwise. Placing the pieces in water bowls and spacing them out on the floor can help absorb the harmful fumes produced by the polyurethane.
Lemons have properties that are analogous to onions.
It has been used for decades to combat various scents found inside the home.
Utilize the Natural Fume Remover from VAPORSORB.
On the polyurethane-coated floor that has been finished, a large amount of VAPORSORB granules should be sprinkled.
It would help if you waited many hours, or perhaps overnight, before proceeding.
The residual noxious vapors will be drawn out by these vapor-absorbent grains and then absorbed.
After some time has passed, the granules should be swept up and, if necessary, re-scattered to ensure that all odors have been removed.
Try using activated charcoal.
Activated charcoal is another natural cure that might assist you in overcoming the pungent odors caused by polyurethane.
This item has an extremely high level of dryness and is very effective at removing impurities from the air and absorbing moisture.
Put them in saucer plates, and then place the plates on the floors that have just recently been finished.

You will need to replace them every few days until the unpleasant odor disappears entirely.
Utilization of baking soda within the space
Baking soda is another absorbent substance that might contribute to the cleaning of the air.
Please put them on paper plates or newspapers and disperse them over the room’s afflicted area in numerous locations.
Both paper and baking soda have a high absorption capacity and will quickly eliminate any lingering scents.
White vinegar that has been distilled.
Vinegar of white grapes can also be used to revitalize the atmosphere throughout your entire home.
Place some of this vinegar in little containers, then set those containers in the four corners of the floor that have been varnished.
Allow it to sit out overnight, then replenish the ingredients as required.
You can also slowly simmer a portion of the vinegar for approximately one hour.
Again, the irritating odors will be eliminated due to the acidic vapors since they will attract the volatile chemicals, break them down, and then eliminate them.
Raise the Temperature
The drying process of varnish can be sped up by applying heat.
Since this is the case, the sooner it dries, the sooner the area will be habitable again.
In light of the preceding, ensure that the windows are shut throughout the day and that the temperature within the home is increased to hasten the curing process of the polyurethane.
Keep everyone, including dogs, outside the house while this process is being completed because it is almost certain that the atmosphere inside will become intolerable.
Keep the temperature steady until the polyurethane has completely hardened.
After that, ventilate the home as much as you possibly can and make use of all of the absorbent materials that were discussed earlier.

Once the curing process is complete, neither of them will pose a threat.
After applying polyurethane, will I be able to sleep in my house?
