How To Open A Paint Can?

It cannot be opened because the paint cannot be exposed to a large amount of air, so it is sealed. The principle is to open a small opening to let air in and it will be easy to open. It is important to seal the open paint bucket when you close the lid after use. When using, pour out as much as you need to cover the bucket, so as to minimize the contact between the paint in the bucket and the air so that it will not dry easily. Open the lid 45 degrees. There is a sealing rubber gasket on the lower half of the lid. Be sure not to break it. This is the key to ensuring the sealing. The better the sealing, the longer the storage time.
