How to Extend the Shelf Life of Your Remaining Paint

No matter how carefully you estimate the paint required for a project there will always be some leftover paints. But you shouldn’t dispose of leftover paints.  You can use remaining paint for touchups later on. 
In this blog post, you will learn some tips to prolong the shelf life of your paint. This will help you save costs on touchups whenever required in the future. 

1. Proper Storage 
Proper storage of the paint is important to extend the paint’s shelf life. Paints can last for years without decaying when they are stored properly. Here are some tips for proper storage of the paint for later use.
  • Always keep the paint can in upside position.
  • Avoid placing the can in a high or low temperature to preserve paint quality. 
  • Ensure that the paint can is stored in a cool and dry place

2. Avoid Paint Flakes 
Paint that is leftover in the can develops into flakes over time. Removing the flakes can result in a mess. To avoid the mess, you should consider placing wax paper or aluminum foil under the lid. 
Trace out and cut a circle and drop it gently over the paint. When using the leftover paint, simply take out the foil and you won’t have to deal with the messy flakes. 

3. Completely Seal the Lid
Place a plastic wrap inside the paint can before closing the lid. This will result in a good seal extending the paint’s shelf life. Paint won’t be exposed to oxygen thereby extending the shelf life. 
Another great idea to prevent exposure of the paint is to blow a balloon about the size of the remaining space inside the can and place it inside before putting the plastic wrap. This will ensure that the paint remains fresh for a long time. 

4. Use Only the Amount Required 
When you are painting, you should consider transferring the amount required for the surface in a separate container. This will reduce exposure of the paint to the air thereby extending its shelf life. 
You should also not add water to the paint can. This will spoil the paint inside and also result in mold formation.  Moreover, you should not load the roller or brush directly from the can. This will introduce contaminants to the fresh paint. 
Consider taking out the amount of paint you need and add water in a separate container. You can then dispose of the diluted paint in a safe manner. This will ensure that the remaining paint remains unspoiled and can be used later on for touchups.  

Final Remarks!
Remember that leftover paints cannot be used for touch-ups of exterior surfaces. The reason is that the paint on the exterior surfaces will fade due to direct exposure to the sun. So, the stored paint will be of a different shade when you use it for touch-ups later on. You can use leftover paints for the touchup of small areas inside the house.
