What Type of Paint Lasts the Longest?

When it comes to paint that will last for years, acrylic paint is an excellent choice. It is highly resistant to fading or damage caused by exposure to the sun, making it ideal for homes in warm climates. Inorganic colors such as those listed above are also known for their durability. For an outer layer that will stand the test of time, opt for a reflective color with no red pigmentation.

Oil-based paint has the longest lifespan of any type of paint, provided it is stored in a sealed container. However, milk proteins added to this type of paint give it a short shelf life of just a few days to a week once it's mixed. If the paint smells bad in the can, it will smell bad on the walls, so it's best to avoid using it and buy a new can instead. Latex, oil-based acrylic, chalk and milk paint all have their own expiration dates.

A can that has been properly opened and sealed can last up to 10 years in storage, while unopened paint can last up to 15 years.

UV Rays and Paint Durability

The most important factor to consider when choosing outdoor paint colors is that UV rays can cause the paint to deteriorate over time. If you detect a rancid odor in the paint, this is likely due to bacterial growth and you should not use it. Poorly stored paint can spoil or be prone to peeling faster, so you should always inspect it carefully before using it.

To ensure your exterior paint lasts a long time, opt for a light color.

Freeze-Thaw Cycles and Paint Quality

Freeze-thaw cycles can cause paint to become clumpy and prevent you from achieving a smooth finish when painting your walls. Additionally, make sure that the paint you choose does not seep through the pores of the stucco surface or it could stain the foundation walls. Primers are also important as they seal the wood and prevent moisture from seeping into the wood and drying it out, which can cause cracks and peeling.

Checking Paint Quality Before Use If you are unsure if the paint can be used or not, consult a professional at your local paint store for advice. Before starting any project, check that the paint hasn't been damaged while in storage. If you suspect that it has been damaged, go to the store for a professional opinion.
