Most water-based paint takes between a few days and two weeks to cure fully. Little Greene say their Intelligent finishes reach full hardness in up to seven days, while Farrow & Ball advise that some darker colours take up to 14 days to achieve full hardness, strength and durability. The paint will feel dry within an hour or two, but it is still soft underneath for some time after that.
What that means in practice depends on what you have painted. A bedroom wall that nobody touches can be lived with almost straight away. A kitchen cabinet door that is opened twenty times a day, or a chest of drawers with a lamp on top, needs a little more patience. Here is a practical timeline for each.

Walls and ceilings
Walls get the least wear, so they are the most forgiving.
- Same day. Farrow & Ball emulsions are dry in 2 hours, and Little Greene's Intelligent Matt Emulsion is surface dry in around 30 minutes. You can use the room once you have finished.
- After a few days. Rehang pictures and mirrors and push furniture back against the wall.
- After a week or two. Clean the wall properly. Farrow & Ball recommend allowing at least 14 days before cleaning Modern Emulsion. Little Greene say Intelligent Matt Emulsion cures in 3 to 7 days depending on how thickly it was applied, and that its final sheen may take up to seven days to appear.
Flat finishes such as Farrow & Ball Estate Emulsion are gently wipeable rather than washable even when cured, so choose a more durable finish for hallways and family rooms.
Woodwork: skirtings, doors and kitchen cabinets
Woodwork takes knocks, hands and the rubbing of door against frame, so it needs to be properly hard before it is put to work.
- Doors. Leave freshly painted doors slightly ajar for the first day or two so the painted faces do not stick to the frame or stop.
- Skirtings. Keep vacuum cleaners and furniture away from them for the first few days.
- Kitchen cabinets. Handle carefully for the first week and wait before wiping them down with anything more than a damp cloth.
Little Greene's Intelligent Eggshell, Intelligent Satin and Intelligent Gloss reach full hardness in up to 7 days. For Farrow & Ball Flat Eggshell in a deep colour, allow the full 14 days before treating it as fully durable.

Painted furniture
Furniture is where curing matters most, because tops and shelves carry weight and drawers rub against carcasses.
- The next day. Reassemble carefully and use for light duties.
- The first week. Avoid heavy objects on tops and shelves, and do not stand anything hot or wet on the paint.
- After about a week. Little Greene's Intelligent finishes will have reached full hardness, and the piece can be used normally.

What slows curing down
- Cold. Keep the room above the brand's minimum: 10°C for Farrow & Ball and 8°C for Little Greene's Intelligent range.
- Damp air. Humidity slows evaporation, so ventilate kitchens and bathrooms well.
- Thick coats. Two thin coats cure faster and more evenly than one heavy one.
- Dark colours. Deeper shades can take longer to reach full hardness, as Farrow & Ball note.
Questions we are often asked
How can I tell if paint has cured?
There is no simple test at home. If the recommended time has passed and the surface no longer feels slightly soft or tacky when pressed with a fingernail in an inconspicuous spot, it is ready for normal use.
Can I speed up curing?
Only by giving the paint good conditions: steady warmth, fresh air and thin coats. Nothing makes a properly applied coat cure much faster.
Is drying the same as curing?
No. Drying is the water leaving the paint; curing is the film hardening afterwards. A wall can be dry in an hour and still be days away from full hardness.
