How to Ventilate a Room While Painting

Ventilate a room after painting

Proper air circulation helps you achieve optimal results on a painting project. It’s also a great way to safeguard your well-being and protect your environment and surroundings. So before embarking on your next painting project, learn how to ventilate a room while painting.

Below is a simple guide to help you keep your house adequately ventilated while painting. From the best methods to a few troubleshooting tips, learn everything you need to know below.

Methods of Ventilation

Insufficient ventilation can leave you vulnerable to volatile organic compounds (VOCs) and toxic fumes from paint and solvent products. A study on Non-occupational exposure to paint fumes during pregnancy and risk of congenital anomalies by Hjortebjerg D, Andersen AM, Garne E, Raaschou-Nielsen O, Sørensen M, even found that prolonged exposure to paint fumes can have a detrimental effect on fetuses. Here are some of the best methods on how to ventilate a room while painting:

Open Doors and Windows

First, you must create natural airflow in your room before painting. The simplest way to do that is by opening the doors and windows. Keep them ajar throughout the project’s duration.

However, it’s also essential to keep an eye on outdoor conditions. If the weather is terrible or you live in a high-pollution area, opening your doors and windows may be unwise.

Use Exhaust Fans

You should also turn on your exhaust fans before starting the interior painting project. Position them near your open doors and windows so they can easily direct the harmful fumes and smells outside.

If you can’t open all your doors and windows due to bad weather or pollution, you can just open one and place the fan nearby. That way, you can still eliminate the bad smells while preventing the elements outside from coming in.

Try Cross-Ventilation Systems

You should also consider creating a cross-ventilation system. This means strategically placing fans on opposite sides of the work area. Through this setup, you can promote proper air circulation and do away with paint fumes.

Install Window Fans

Or you can install window fans in your room before starting the painting project. Get at least one fan to blow air out and another to draw fresh air in. This will help promote better airflow in your room. Plus, it will eliminate any ventilation issues in future painting projects.

Get Portable Air Purifiers

Air purifiers are designed for cleaning your room’s environment. Some units even have features specifically built to get rid of harmful particles like VOCs and paint fumes. You can keep the area well-ventilated by placing them in the work area before a painting project.

Safety Precautions

Knowing how to ventilate a room while painting is essential for a safe and healthy environment. It’s equally important to follow certain safety precautions to minimise the risks of paint fumes and chemicals. Here are some safety measures to consider:

Protective Gear

Wear appropriate personal protective equipment (PPE) before you start the project. These include respirators, masks, safety goggles, gloves, and suitable clothing. Having these can prevent or minimise your contact with paint and fumes.

Keep Your Children and Pets Away

Before you whip out your paintbrush, make sure your children or pets are not in the room. Fumes can be harmful to their respiratory health, as W. Balogun and his colleagues noted in their study. Plus, they might end up causing a mess if they make contact with wet paint.

Avoid Smoking or Flames

Obviously, you should refrain from smoking or bringing any open flames near the work area. Stone or wood paint fumes are highly flammable. If you’re careless, you might end up dealing with a severe fire hazard.

Get Low-VOC Paints

Certain painting products come with low VOCs, making them safer and more practical than regular paint. So while you’re still planning your painting project, consider getting these products.

Follow Manufacturer Recommendations

Speaking of paint products, you should always read and follow the manufacturer’s guidelines for proper use, ventilation, and disposal. That way, you can navigate the specific requirements of the paint you’re using.

Troubleshooting Tips When Ventilating a Room

Despite your best efforts, challenges may still arise as you improve air circulation in your room before painting. By knowing how to troubleshoot common issues, you can better ensure proper ventilation. Here are five tips to consider:

Inadequate Airflow

Consider placing additional fans strategically if the room’s ventilation isn’t sufficient. Position fans near windows to create a stronger flow of fresh air and help disperse paint fumes more effectively. Or you can try the cross-ventilation system mentioned earlier.

Strong Crosswinds

Powerful outdoor crosswinds can disrupt the desired airflow pattern. Partially close some of your windows to control the direction of air movement.

Limited Windows and Doors

You might need more natural ventilation if your room only has one door and few windows. Place more fans or air purifiers strategically to improve airflow.

Lingering Paint Odours

Say the paint odours persist even after proper ventilation. You may need to extend the duration of the ventilation process to remedy this. Allow more time for fresh air to circulate and expel the fumes.

Weather Conditions

As mentioned above, weather conditions can impact the effectiveness of your ventilation efforts. If you want to paint during heavy rains or extreme cold months, you may need to adjust your strategy by relying on more fans rather than opening your windows and doors. Or you can postpone the project to ensure safety and ventilation quality.

How Long Do You Have to Let Paint Fumes Air Out?

Generally speaking, we recommend spending at least 2 to 3 days to let the paint fumes dissipate upon finishing your painting project. Bear in mind that the overall time needed to get rid of bad painting smells will depend on several factors, from the type of product used to the room’s size. Through the methods we mentioned above, you can make this process quicker.

Secret Ingredients to Get Rid of Paint Fumes Faster

Baking Soda and Water

Place bowls of water with a few tablespoons of baking soda around the room to help absorb the paint fumes and other unpleasant smells.


Known for its odour-absorbing properties, you can also place activated charcoal in open containers in the room.


Alternatively, you can cut an onion into quarters and then place them around the room. They’ll also help absorb the paint fumes.

Vinegar Solution

Or mix water and vinegar in a bowl to neutralise the paint fumes and other foul odours. Place them on the floor or on a small table.

Coffee Grounds

Lastly, leave open containers of coffee grounds in the room to help mask or absorb the fumes.

Tips When Getting Low-VOC Paint

As mentioned above, opting for low-VOC paint is an intelligent choice to ensure proper ventilation before painting. Here are five crucial tips to consider when getting them:

Read Labels Thoroughly

Look for labels that clearly state “low VOC” or “zero VOC.” Verify this information on the paint can itself, not just the promotional materials.

Research Brands

Not all low-VOC paints are created equal. Look for reputable brands known for producing high-quality, low-VOC options. Read reviews and seek recommendations if necessary.

Check Colour Availability

Some low-VOC paints have limitations in colour choices. Confirm that the desired colour is available in the low VOC range before making your final decision.

Test Before Committing

Purchase a sample of the low VOC paint and test it on a small, inconspicuous area of your wall. This ensures you’re satisfied with the colour, finish, and application quality.

Confirm Coverage and Application

Low VOC paints can differ in coverage and application methods from traditional paints. Read the product instructions to understand any specific requirements for priming, number of coats, or drying times.

Seeking Professional Help

If you’re dealing with larger painting projects, best seek expert service when ventilating the area. Professional painters have the expertise and know-how to ensure proper air circulation in a painting project.

What’s more, if you have specific medical conditions that make interaction with paint fumes dangerous, hiring a professional painter is the better option. That way, you can stay safe and use your time on more important matters.


Giving your living space a fresh coat of paint can be fun and worthwhile. However, this makeover shouldn’t come at the cost of your health and safety.
