Before using the paint, it would be nice to stir the paint first. This also applies to new paint. The benefit of stirring is to ensure that the ingredients are well mixed.

One of the signs of expired paint is the color pigments settling at the bottom and the chemicals floating at the top. This can usually be remedied with a professional paint stirrer. However, you need to pay attention to the age of the paint again. The older the paint, the harder it is to mix.

To maintain the quality of the paint, you also need to store it in the right area. Below are some of the proper ways to store paint.

1. Proper storage

Where you store your paint cans is one of the most important considerations. Most types of paint should be stored in a cool, dry location, such as a basement.

2. Check for an airtight seal

The best way to create an airtight seal on a paint can is to close the lid, then turn the paint can upside down. This way, the paint liquid is pressed against the inside of the lid and no air gets in.

3. Avoid contamination

To prevent the addition of bacteria or mold to the paint, pour the paint into a tray or cup before painting. Then discard the remaining paint residue rather than pouring it back into the paint can. Also, avoid dipping brushes or rollers directly into the can, and leaving the lid open when the paint is not in use.
