Safe house painting starts with the right paint and good ventilation. Choose low-VOC or non-toxic wall paint, keep doors and windows open while painting and drying, and keep children, pets and elderly family members away from fresh fumes. Test older homes for lead paint before sanding, wear gloves, goggles and a mask, and store and dispose of leftover paint responsibly. Professional painters follow these safety precautions as standard.

For small jobs with low-VOC water-based paint and good ventilation, most healthy adults can stay at home, ideally in rooms away from the work. For full-house painting, or if the household includes infants, pregnant women, elderly members or people with asthma, it's better to stay elsewhere or sleep in unpainted rooms until the smell clears, usually one to two days.
Low-VOC paint contains reduced levels of volatile organic compounds, the solvents that evaporate as paint dries and cause the strong smell. 'Non-toxic' is a broader marketing term and has no single standard, so check the product's VOC content, certifications and safety data sheet rather than relying on the label. For homes, a water-based, low-VOC interior emulsion is the practical safe choice.
Keep windows and doors open to create cross-ventilation and run fans facing outward to push fumes out. Bowls of baking soda or activated charcoal placed in the room can absorb some odour. Avoid closing the room with an air conditioner on recirculation during the first day. Using low-odour, water-based paint from the start is the most effective way to limit smell.
Bedrooms, nurseries and kids rooms need the most care because people spend long hours there, so paint them first and let them air out longest. Kitchens need gas and heat sources switched off during painting. Bathrooms and small rooms with poor airflow need exhaust fans running. Staircases and high walls need stable ladders or scaffolding to prevent falls.
Clean water-based paint from brushes and rollers with soap and water in a bucket, not directly under a running tap into the drain. Let the paint solids settle, pour off the clear water and dispose of the sludge with dry waste once it hardens. Solvent-based paints need thinner; use it in a ventilated area, away from flames, and never pour used thinner into drains.
It's generally advised that pregnant women avoid doing the painting themselves, especially sanding old paint or using solvent-based products. If painting is unavoidable, use water-based, low-VOC paint, keep the area well ventilated, and stay out of freshly painted rooms until the smell clears. Discuss specific concerns with your doctor. Ask someone else to handle sanding and cleanup, too.
