Proper paint storage is crucial to prolong the life of the paint. Paint can be expensive and needs to be stored properly to be able to reuse.
Always use a paint can opener to open the lid. DO NOT use a screwdriver or a sharp edge. This can distort the lid making it harder to properly close and seal the can later.
The life of paint also depends how you use it.
In between pours, be sure to keep the lid closed. This can be done by tapping it shut. Never use a hammer to close the lid.
The paint storage location is crucial for a long paint shelf-life. Paint should be protected from extreme temperatures – especially from freezing and also from direct sunlight. It needs to be kept in a dry place to keep it away from moisture.
