Once a can of paint has been opened dirt may contaminate it or a skin may form on the surface. To prevent any contamination, always replace the lid after use and store the can upside down.
1. To prevent debris on the can surface from falling into the paint; brush the rim with a paintbrush.
2. Work around the rim of the lid with the blunt edge of a flat-bladed knife, prying the lid until it springs open.
3. Stir the paint with a piece of wooden doweling in wide and narrow circles to give a consistent color.
WHY USE A PAINT BUCKET?
It makes sense to work out of a paint bucket rather than paint can. It will enable you to transfer as much paint as you need at one time, and a bucket with a handle can be hung from a ladder. Once you have mixed the paint, pour as much as you need into the bucket. Line the bucket with aluminum foil before you fill it, as paint can be difficult to remove. Place the foil with the shiny surface up.
