How Long Should Exterior and Interior Paint Last

Content Table

    There is a multitude of reasons why getting a new paint job can freshen up a home or building. But the question many ask right after the paint is applied is “how long does a paint job last?”. The answer depends on quite some different factors, including whether or not you’ve just had your home painted or whether you have a commercial property that was just painted.

    In this article, we’ll go through the factors that influence paint lifespan so that you can learn how to get the most out of your investment in quality paint and the process of getting an exterior or interior paint job. There are different answers to the questions of “how long does interior paint last” versus “what is the exterior paint life expectancy,” and we’ll get into all of the details below.

    At Oahu Pro Painters, we believe it’s important for any homeowners, business owners, or building owners to be as informed as possible when it comes to painting life expectancy, so let’s dig into the details now!

    How Long Should House Paint Last?

    If you’re wondering, “how long does paint last?”, you should also be thinking about whether the paintwork is interior or exterior. Interior paint, in general, will last for about 5 to 10 years depending on humidity and sun exposure. Exterior paint life expectancy is a little different as it is much more affected by climate conditions, but it should last about 5 to 7 years. Even a high-quality paint job will eventually need refreshing, but there are different considerations relating to painting lifespan indoors and outdoors. Let’s take a look at some of them.

    How Long Does Interior Paint Last?

    First, let’s focus on your interior paint job and the question “how long does wall paint last?”. As mentioned above, interior paint jobs last quite a while (up to about 10 years) depending on various factors. But, most homeowners and building owners decide to switch up their paint well before the signs of peeling or fading show up, since it’s one of the easiest ways to freshen up a room and make it look almost entirely new. Let’s take a look at the most important factors when it comes to the longevity of your interior and ways to make your paint job last longer.

    Paint Quality and Type

    Skimping on the price of your interior paint is not going to do you any favors, because you’re simply going to end up paying for it in the end anyway. Cheaper paints are more likely to peel away and fade more quickly, so finding a higher-quality paint that fits your budget is essential.

    Here are some ways to determine whether or not paint is of high quality to ensure the highest quality house painting:

    • Price: A decent rule of thumb when it comes to finding high-quality interior paint is a price point of about $30 or more per gallon. 
    • Splatter: If the paint doesn’t splatter as much when you’re rolling it on, you know you have a higher quality paint. The lesser the splatter, the better the paint.
    • Abrasion Resistance: Look for paint with high abrasion resistance. This means the paint is more durable and can handle a little more wear and tear.
    • The Manufacturer’s Range: Probably the easiest way to tell if a paint is of high quality is simply by looking at the specific range of that particular manufacturer. Each manufacturer typically has several ranges, including lower-budget ones and premium ones. Opt for the highest level within the range that you can afford. 

    You also need to examine the different types of paints to see which is right for your interior, including the following:

    Oil Based Paints

    Oil-based paints are probably the most durable, but many have been taken off the market due to their higher levels of volatile organic compounds that give off strong odors and may cause health risks. The drying time for an oil-based paint is 6-8 hours, and it’s far more difficult to clean than the alternatives. 

    Water Based Paints

    Water-based paints are more environmentally friendly and better for your overall health than oil-based paints, as they contain much lower levels of volatile organic compounds. Water-based paints are less expensive as well but are still quite sturdy.

    Latex Based Paints

    If you live in an especially humid or rainy area, latex-based paints can be a good option because of their especially quick drying time. The only downside is that these paints are far less durable than the other interior paint options.


    Color has a huge impact on your paintwork’s durability in an indoor environment, too. Lighter colors will more easily show marks, scuffs, and dings in your paintwork. And while a dark color might feel like the obvious alternative to avoid more frequent repainting, you’ll then face the problem of colors fading more quickly. That’s particularly true in places like Hawaii where the sun shines and fills any room with even a small window.

    Right Primer

    You should never skip the priming stage! A good-quality primer will prepare the wall for paint and help it stick. Without primer, your first layer of paint may simply be absorbed by the plater or wood, and the second layer of paint will not look as bold as it should.

    If you’re using acrylic latex paint, make sure you choose either an oil-based or water-based primer before you start painting. And if you’re using oil-based paint, you’ll need to use an oil-based primer as well.

    With a solid foundation of primer, your paint will be well prepared to last for years without peeling or flaking.
