How to Read a Paint Can: Finishes, Coverage, and Prep
Choosing paint can feel like picking from endless colours, but the information on the can matters just as much as the shade. The label tells you what the paint is made of, where to use it, and how to apply it. Here is what to look for.
Finish
- Flat or matte. Hides imperfections and has no shine, but marks more easily. Often used on ceilings and low-traffic walls.
- Eggshell. A soft sheen that is easy to wipe, popular for living areas.
- Satin. Slightly glossier and more durable, good for hallways and kids’ rooms.
- Semi-gloss and gloss. Hard-wearing and easy to clean, used on trim, doors, and kitchens or bathrooms.
Base type
Water-based (latex or acrylic) paints dry quickly, clean up with water, and have lower odour. Oil-based paints can give a very hard finish but take longer to dry and need solvents for cleaning. Check which one suits the surface and the room.
Coverage
The label gives an estimate of the area one litre or gallon will cover, often around 9 to 10 square metres per litre (350 to 400 square feet per gallon), but it varies. Measure your walls, subtract windows and doors, and plan for two coats. Rough or dark surfaces use more.
Drying and recoat times
Look for the time until the paint is dry to the touch and the time before you can apply a second coat. These depend on temperature and humidity, so allow longer in cold or damp conditions.
Surface preparation
The can will list how to prepare the surface, including cleaning, sanding, and priming. Following these instructions has a big effect on the result and the durability.
VOC and safety
Many labels list volatile organic compound (VOC) content. Low-VOC paints produce fewer fumes. Whatever you choose, ventilate the room and keep paint away from children and pets.
Buying tips
- Buy all the paint for one room at the same time, and mix cans together to keep the colour consistent.
- Test a small sample on the wall and look at it at different times of day.
- Keep leftover paint tightly sealed and note the colour name and code.
Spend a few minutes reading the can, and you can save yourself time and money.
