A fresh coat of paint can instantly transform your living space—but if you’re painting indoors, you may wonder whether it’s safe to stay home during the process. Paint fumes, ventilation, and drying times all play a role in ensuring comfort and safety. Here’s what you should know before starting your next indoor painting project.
Is it safe to stay in the house while painting?
In most cases, yes, it’s safe to remain at home during indoor painting—especially when using low-VOC or zero-VOC paints. These modern formulations emit minimal odour and fewer airborne chemicals, making them much safer than traditional oil-based products.
However, good ventilation and airflow are essential. Keep windows open, use fans, and avoid staying for long periods in freshly painted rooms until the air feels completely clear.
What are VOCs and why do they matter?
VOCs (volatile organic compounds) are chemicals found in some paints that evaporate into the air during drying. High levels of VOCs can cause headaches, dizziness, or respiratory irritation, particularly in poorly ventilated areas.
Choosing low- or zero-VOC paints, available at Randall’s Paint Collectionshelps reduce these risks while still delivering rich colour and lasting durability.
How long should I wait before using a freshly painted room?
It depends on the type of paint and ventilation quality:
-
Low-VOC or latex paint: Wait 2–4 hours before light use, and 24 hours for full airing.
- Oil-based paint: Wait at least 48–72 hours before reoccupying the space.
Always keep windows open during and after painting to allow fumes to dissipate.
Are paint fumes harmful to children or pets?
Children, pets, and individuals with allergies or respiratory conditions are more sensitive to paint odours and chemicals. To be safe:
- Keep them out of the painted area until the paint is completely dry.
- Use low-odour, zero-VOC paints to minimize any health concerns.
- Ensure proper airflow for at least 24–48 hours before allowing them back in.
Randall’s experts can help you select paint lines that meet the strictest air-quality standards.
What are the best ventilation practices while painting indoors?
Proper ventilation helps speed up drying and prevents fume buildup. Follow these steps:
-
Open windows and doors in the painted area.
-
Set up fans to move air outdoors.
-
Avoid painting in closed spaces like bathrooms without airflow.
-
If possible, run your HVAC fan to circulate fresh air through the home.
For Ottawa homes during colder months, ventilate in short intervals while keeping interior temperatures between 10°C and 25°C for optimal drying.
Can I paint safely during winter when windows can’t stay open?
Yes—with a few precautions. Modern paints like those found at Randall’s Collections
are formulated for low odour and faster curing, making them safe for winter projects.
- Keep the room well ventilated with fans or air purifiers.
- Paint during the warmest part of the day.
- Avoid overcrowding freshly painted rooms for at least 24 hours.
Do different paint types affect indoor air quality differently?
Yes. Here’s how they compare:
-
Latex (water-based) paint: Low odour and quick-drying; safe for most interior projects.
-
Oil-based paint: Stronger fumes and longer drying time; best for trim and doors, not enclosed spaces.
- Zero-VOC paint: Virtually odourless and safest for sensitive individuals or households.
Randall’s carries a full range of eco-friendly and low-emission paints for every surface and room type.
Should I leave the house if professional painters are working indoors?
Not necessarily. Professional painters are trained to manage ventilation, minimize odours, and choose suitable products for occupied homes. If you have allergies or sensitivities, you can:
- Stay in another part of the home until the area is aired out.
- Schedule painting when you’ll be away for the day.
- Inform the painter in advance so they can use low-VOC options.

What can I do to keep my home fresh after painting?
- Leave windows slightly open for a few days, weather permitting.
- Place activated charcoal or baking soda bowls in the room to absorb odours.
- Use an air purifier with a HEPA filter.
- Wipe down nearby surfaces to remove any residual dust.
Your space will feel completely fresh once the paint has fully cured.
