How to use it
- Type the room
Its length, width and height, and how many doors and windows it has.
- Coats and coverage
How many coats, and the coverage printed on the can.
- Set the can
Type your can size or tap a usual one.
Tips
- Read the can
Coverage differs from paint to paint. The label gives it per litre or per gallon.
- Two coats
A new color or fresh plaster usually takes two coats, and sometimes a primer first.
- Mix the cans
With several cans of one tinted color, mix them together in a bucket so the shade matches across the wall.
