The cold weather can be harsh, not just to you, but to your paint too. Most homeowners are aware that the weather can cause the paint on walls to crack and chip, but did you know that it could also shorten the lifespan of your safely stored old paint? And not just the weather, but the type of paint also has to say a lot about its lifespan. In fact, you should be asking—Was the container of paint already open? How well was the container sealed? Where has it been stored? At what temperature has the paint been stored? All these questions become extremely important when you’re planning to reuse your old, well-kept paint to ensure it hasn’t gone bad yet and is still good for the walls. After all, while reusing paint is a great idea to go green and save money, but not so much if is not in the condition of being used at all—you’ll then only be wasting all your time, money, and effort.
In this blog post, we will explore how long different types of paint last in different environments, and offer tips on how to make them last as long as possible!
Paint Types and Their Lifespans
Different types of paint have different lifespans. For instance, latex paint typically lasts between two and ten years, while acrylic paint can last up to fifteen. Chalk paint has a shorter lifespan of one to five years, and milk paint (both premixed and mixed from powder form) only lasts one to two years. Here are some common types of paints and their lifespans under different conditions:
Oil-Based Acrylic Paint is thick and renders a beautiful finish on every surface. Unlike most water-based paints, oil paint contains volatile organic compounds (VOCs), which make it more likely to separate on the shelf when left for a long period of time—a simple stir will restore it back to normal, and there you’re, good to paint.
While oil-based paints flaunt the longest lifespan of up to 15 years on the shelf, when not sealed properly in a container, they will dry out rather quickly. The paint also releases toxins when it dries, which are highly flammable and can cause a fire. A properly sealed/resealed oil paint can easily last a decade or even more in storage.
Chalk Paint is extremely smooth and thick paint, ideal for small areas like doors or furniture, delivering a smooth matte finish. A properly sealed and stored can of chalk paint lasts 1 to 5 years, but if exposed to air can dry up very fast. If you have a used can of chalk paint that has thickened, you can simply add some water to use it again.
Milk Paint is a thick paint with zero harmful chemicals, which makes it ideal for spaces for kids or animals, but not so much when it comes to storage as it comes with the shortest life span. Consisting of added milk proteins, milk paint can only last only a few days or a week after it’s mixed. However, these days, you can also find pre-mixed milk paints that last up to a year on the market shelf—if sealed properly. It must be refrigerated if you’re planning on taking a break between the job or you might find it dried out when back.
Latex Paint is versatile, most commonly used water-based paint for both interior and exterior projects. Made using water, it contains less toxic than its oil-based peers, which also makes it more susceptible to freezing. If stored properly, it can last from 2 to 10 years, depending on the storage situation. For instance, if you live in a cold city and are storing the latex paint in your garage or similar area with no temperature control, the paint is highly likely to go lumpy. Minor lumps can be dissolved using a paint stick, but if there are multiple and big lumps, it is time you bid the paint adieu for good and buy a fresh can for your walls.
How To Tell If Paint Has Gone Bad?
Is your paint lumpy, smelly, or chunky? Then look no further for other descriptors, these are speaking in lengths already that your paint has gone bad. It could be because of exposure to continuous thaw and freeze cycles in extremely cold temperatures, making it lumpy. Paints that have lumps result in a rough and untidy texture and will make it difficult to apply even a single coat.
Another trait of bad paint—rancid odor—is indicative of bacterial growth, meaning the paint is not good to use anymore. If it smells bad in the container, it will make your walls smell bad as well, so it’s better to buy a fresh lot.
Typically, you can tell if the paint has gone bad if it is lumpy or if it has a bad odor. Paint that has been stored in a cool, dry place will last the longest. You should also check to see if the container of paint was already open and how well it was sealed before you store it. If you are not sure whether the paint is still good, you can always ask a professional at the paint store. Proper disposal of old paint is important, so be sure to check with your local city ordinances to see how you should dispose of it.
Is Separated Paint Bad?
No, separated paint is a common train and happens when the can is left on the shelf for a long time period. It is not bad yet and can easily be restored to normal by simply turning the can upside down so that it mixes well. You can also use a stick to bring the paint back together. If you’re still unsure if the paint is good for walls or not, a visit to the local shop will be a good idea that the risk to spoil your walls and efforts.
