Just repainted and the smell will not go? Here is what causes it, what affects how long it lasts, and how to clear it.

Paint smell comes from volatile organic compounds (VOCs) and other chemicals released as the paint dries, and how long it lasts depends on the product, how many coats went on and, above all, how well the room is ventilated. There is no single safe number of hours: follow the drying and ventilation guidance on the tin and the maker's datasheet, keep windows open and air moving during and after painting, and choose a low-VOC or low-odour paint for bedrooms and nurseries. On our guides a standard bedroom repaint is RM400–RM700 (indicative 2026, Klang Valley).
Paints contain organic solvents and other ingredients that evaporate as the film dries. These volatile organic compounds (VOCs) are what you smell. The US Environmental Protection Agency notes that paints, varnishes and wax all contain organic solvents, that these products release organic compounds while you use them, and that elevated concentrations can persist in the air long after the activity is completed.
Water-based emulsions, which are used for most Malaysian interior walls and ceilings, generally smell much less than solvent-based enamels and varnishes used on doors, grilles and timber. Our paint types guide explains which paint goes where.
It depends on four things: the product, the number of coats, the weather and the ventilation. A water-based emulsion in a room with windows open and a fan running clears far faster than a solvent-based varnish in a closed room with the aircon on. Humid, still air slows drying, and a room full of new furniture and curtains holds the smell longer.
Paint makers publish drying and recoat times, and ventilation instructions, on the tin and in the product's technical data sheet. That is the only reliable guide for a specific paint. Be wary of any quote that promises a fixed number of hours for every product; ask which paint series will be used and read its datasheet.
The EPA lists eye, nose and throat irritation, headaches, loss of coordination and nausea among the possible health effects of VOCs, and says the effect depends on how much you are exposed to and for how long. Some people are more sensitive than others. Babies, young children, pregnant women, older people and anyone with asthma or allergies should stay out of freshly painted rooms until the smell has gone. If you are pregnant or have a health condition, ask your doctor before moving back in.
If anyone feels dizzy, gets a headache or has trouble breathing, leave the room, get fresh air and increase ventilation.
Most paint brands sell a low-VOC, low-odour or odour-less interior series. These reduce the smell and the chemicals released, but low is not zero, and "odour-less" describes what you smell, not everything that is released. Compare products using the maker's datasheet and safety data sheet rather than the name on the can, and write the exact paint series into the quotation so it is not swapped for a cheaper one.
When you read a datasheet, look for four things: the touch-dry time, the recoat time, any ventilation or occupancy note, and whether the maker publishes a VOC content for the product. If the painter cannot tell you which series is going on your walls, ask before the job starts rather than after the smell appears. Primers and sealers count too: a low-odour topcoat over a strong-smelling solvent primer still leaves the room smelling.
| Paint | Typical use | Smell while drying | Notes |
|---|---|---|---|
| Low-VOC / low-odour emulsion | Bedrooms, nurseries, occupied homes | Lowest | Check the datasheet; still ventilate |
| Standard water-based emulsion | Walls and ceilings throughout the house | Mild | Most common interior paint |
| Anti-mould emulsion | Bathrooms, kitchens, damp rooms | Mild | Contains biocide additives |
| Solvent-based enamel or varnish | Doors, grilles, timber, metal | Strong | Do these first or when the house is empty |
| Epoxy and PU coatings | Floors, wet areas | Strong during curing | Keep the area closed off and ventilated |
The EPA's advice is the same in principle: increase ventilation when using products that emit VOCs, and meet or exceed any label precautions. Our DIY painting checklist covers ventilation for a DIY job.
Fresh air is what removes it. Keep ventilating for as long as the smell remains. Bowls of water, charcoal or baking soda may absorb a little, but they are no substitute for airflow. Do not try to cover the smell with air fresheners or scented sprays: the EPA lists air fresheners among household sources of VOCs, so masking adds to the problem rather than solving it.
After a renovation, not every smell is paint. New built-in furniture made from particleboard or MDF can release formaldehyde from the glue in the board; our board formaldehyde grades guide explains what the E-grades on a quotation mean. Sealants, adhesives and floor coatings have their own smells, and a musty smell is usually damp, not paint.
If you are renovating before moving in, sequence the work so the smelliest jobs finish first. Do solvent-based enamels, varnishes and floor coatings early, then wall painting, then the post-renovation clean, and leave time for the house to air before beds, curtains and soft furnishings arrive. Our post-renovation cleaning guide explains where the clean fits in.
If the family has to stay during the work, paint one room at a time with a low-odour series, keep that room closed off and ventilated, and sleep in another room.
