I’m standing on my front porch, admiring the crisp, vibrant finish of my newly painted home, and I can’t help but smile. Valspar Duramax Exterior Paint has transformed my weathered siding into a showstopper, and I’m convinced you’ll love it too.
This paint isn’t just about looks—it’s a shield against the elements, promising durability and low maintenance. Whether you’re tackling a DIY project or hiring a pro, Duramax delivers a professional-grade finish that’s worth every penny.
Trust me, this is the paint you need for your next exterior makeover.
My Journey With Valspar Duramax
Last summer, I decided my 15-year-old house needed a facelift.
The siding was fading, and the trim looked like it had survived a decade of storms—which, to be fair, it had.
I’m no professional painter, but I’m handy enough to take on a project, so I headed to Lowe’s, determined to find a paint that could handle Michigan’s brutal winters and humid summers.
After browsing the aisles and chatting with a store associate, I landed on Valspar Duramax Exterior Paint + Primer. The promise of FlexShield 365 technology, which resists cracking and peeling year-round, hooked me. Plus, the price—around $40 a gallon—wasn’t going to break the bank.
I chose a deep charcoal gray for the siding and a crisp white for the trim, aiming for a modern yet timeless look. Prep work was a slog—power washing, scraping loose paint, and taping off windows—but I followed Valspar’s instructions to the letter.
The paint’s thickness surprised me when I opened the can. It was like stirring pudding, which made me nervous at first. But once I got rolling (literally), the application was smoother than I expected.
The paint clung to my cedar siding without dripping, and the coverage was impressive. One coat hid most of the old color, though I went for two to ensure a flawless finish.
The drying process was quick, even in the humid August air, and the satin finish gave my house a polished glow. A few months later, after a particularly nasty storm, I inspected the paint job.
No peeling, no fading—just a rock-solid finish that looked as fresh as the day I applied it. My neighbors even complimented the transformation, which felt like a win. That experience sold me on Duramax, but I’ve since dug deeper into its strengths and weaknesses to help you decide if it’s right for your home.
What Makes Valspar Duramax Stand Out?
Valspar Duramax isn’t your average exterior paint.
It’s engineered with features that make it a contender for any homeowner looking to protect their investment.
The FlexShield 365 technology is the star of the show, creating a flexible barrier that expands and contracts with your home’s surfaces, resisting cracks and peels even in extreme weather.
I’ve seen it hold up against freezing Michigan winters and scorching summer days, which is no small feat.
The paint also boasts mold, mildew, and algae resistance, a must for anyone living in humid or rainy climates where green streaks can ruin a paint job.
Another standout is the high-hiding formula. This paint covers imperfections like a champ, whether you’re dealing with faded siding or dark stains. I was amazed at how it masked the uneven tones of my old paint with minimal effort.
The built-in primer is a time-saver, too. While I still primed some rough spots, most surfaces needed just one or two coats for full coverage. And let’s talk about the finish options—flat, satin, and semi-gloss—each offering a distinct vibe.
I went with satin for its subtle sheen, but semi-gloss is great for trim if you want extra durability.
Duramax also plays nice with a variety of surfaces: wood, vinyl, brick, stucco, and even primed metal. That versatility means you can use it for everything from siding to shutters.
The low-temperature application range (down to 35°F) extends your painting season, which was a lifesaver when I tackled a late-fall touch-up project. Add in fade-resistant pigments, and you’ve got a paint that keeps your home looking sharp for years.
My house still looks vibrant after a full year, and I’m confident it’ll stay that way.
The Downsides of Valspar Duramax
- Thick Consistency Can Be Tricky
Let’s be real—Duramax’s thickness is a double-edged sword.
While it contributes to excellent coverage, it can feel like wrestling with molasses if you’re not prepared.
I struggled to get a smooth finish with a brush on my trim until I switched to a high-quality roller for larger areas.
Some users on forums like PaintTalk have complained about brush marks that won’t level out, especially if you’re painting in cooler temperatures.
Valspar advises against thinning the paint to meet EPA regulations, but I found that adding a small amount of water (against the rules, I know) helped in a pinch. If you’re a beginner, this thickness might test your patience.
- Coverage Expectations vs. Reality
Valspar markets Duramax as a one-coat wonder, but that’s optimistic for most projects. On my light-colored siding, one coat was nearly enough, but darker or textured surfaces often demand two.
I’ve read reviews on ConsumerAffairs where users were frustrated by the need for multiple coats to cover old paint, especially reds or deep blues. This isn’t a dealbreaker, but it can inflate your budget and time commitment.
If you’re painting over a bold color, factor in extra gallons and elbow grease.
- Customer Service Woes
My experience with Duramax was smooth, but not everyone’s so lucky. Scrolling through PissedConsumer, I noticed complaints about Valspar’s customer service.
Some users reported issues like peeling or tacky paint that never fully dried, and they struggled to get responses from Valspar. One reviewer mentioned waiting six months for a warranty claim with no resolution.
I haven’t had to contact Valspar myself, but it’s worth noting that their support might not match the paint’s quality. If you run into problems, you may need to lean on Lowe’s for help.
- Limited Availability
Duramax is exclusive to Lowe’s, which is convenient if you’ve got one nearby but a hassle if you don’t. I live 10 minutes from a Lowe’s, so this wasn’t an issue, but if you’re in a rural area or prefer shopping elsewhere, you’re out of luck.
Online ordering is an option, but shipping costs can add up for multiple gallons. This exclusivity also means you’re locked into Valspar’s color palette, which, while extensive, might not have the exact shade you’re envisioning.
Comparing Duramax To The Competition
- Sherwin-Williams Duration Exterior
Sherwin-Williams Duration is often the gold standard for exterior paints, and I’ve used it on a rental property in the past. It’s formulated with PermaLast technology, which, like Duramax’s FlexShield, resists peeling and blistering.
Duration’s adhesion is top-notch, especially on tricky surfaces like old oil-based paint, and it handles extreme weather as well as Duramax.
However, at $70-$80 per gallon, it’s nearly double the price. I found Duration slightly easier to apply, with a smoother flow, but the cost made me hesitate for my own home. Duramax offers comparable durability at a fraction of the price, making it the better value for budget-conscious homeowners like me.
- Behr Premium Plus Ultra
Behr Premium Plus Ultra, sold at Home Depot, is another heavy hitter.
Consumer Reports praises its resistance to cracking and dirt, and I’ve seen it used on neighbors’ homes with great results.
It’s priced similarly to Duramax, around $40-$50 per gallon, and offers excellent coverage.
However, Behr struggles with mildew resistance compared to Duramax, which is a dealbreaker in humid climates.
I also found Behr’s finish options less versatile—its satin sheen felt flatter than Duramax’s.
If mildew isn’t a concern and you prefer Home Depot, Behr’s a solid choice, but Duramax edges it out for all-weather performance.
- Benjamin Moore Regal Select Exterior
Benjamin Moore Regal Select is a favorite among pros for its smooth application and rich finish.
I tested it on a friend’s deck years ago, and the color still pops.
It’s ideal for brick and stucco, with strong adhesion and mildew resistance.
But at $60-$70 per gallon, it’s pricier than Duramax, and the coverage isn’t as forgiving on textured surfaces.
Regal Select also requires more prep work, like priming raw wood, which Duramax often skips thanks to its built-in primer.
For a high-end look, Regal Select is tempting, but Duramax delivers similar quality for less.
- PPG Timeless
PPG Timeless, available at PPG stores, is often compared to Duration and Duramax. I haven’t used it myself, but contractors on Fine Homebuilding forums rave about its adhesion and durability, especially on wood.
Priced at $30-$40 per gallon, it’s a budget-friendly rival to Duramax. However, some users report bubbling in cooler temperatures, a problem I never encountered with Duramax.
Timeless also lacks the mold and algae resistance that Duramax emphasizes, which could be an issue in wet climates. If cost is your priority, Timeless is worth considering, but Duramax feels more reliable overall.
Keeping Your Duramax Finish Looking Fresh
- Prep Like a Pro
The secret to a long-lasting Duramax paint job starts before you even open the can. I learned this the hard way when I skipped a thorough cleaning on one section of my siding, only to find dirt trapped under the paint.
Power wash your surfaces to remove dust, chalk, and mildew, and let them dry completely. Scrape off loose paint and sand rough spots for a smooth base.
Valspar recommends applying Duramax when temperatures are between 35°F and 90°F, so check the forecast to avoid painting in extreme cold or heat. Proper prep ensures the paint adheres and performs as promised.
- Apply with Care
Application technique matters as much as the paint itself. I used a high-quality roller for large areas and a synthetic-bristle brush for trim, which helped me avoid streaks. Stir the paint thoroughly—Duramax’s thickness can settle—and intermix multiple cans for consistent color.
Work in small sections, painting back into wet edges to prevent lap marks. If you’re spraying, test your pattern first, as Duramax’s viscosity can clog sprayers if you’re not careful.
Two coats are usually enough, but don’t rush the drying process. Let each coat cure for at least 4 hours, longer in humid conditions.
- Regular Cleaning
To keep your Duramax finish vibrant, clean your exterior annually. I use a garden hose with a mild detergent to wash away dirt and pollen, focusing on high-traffic areas like porches.
For stubborn mildew, a diluted bleach solution works wonders—just rinse thoroughly to avoid damaging the paint. Avoid abrasive scrubbers, as they can dull the finish.
Regular cleaning prevents buildup that could weaken the paint over time, and it keeps your home looking pristine. I’ve found that a quick wash every spring makes a huge difference.
- Inspect and Touch Up
Even a tough paint like Duramax needs occasional TLC. I inspect my house every six months, looking for chips, cracks, or fading. Small touch-ups are easy—clean the area, sand lightly, and apply a thin coat of Duramax with a brush.
For larger repairs, you may need to prime first. Store leftover paint in a cool, dry place to ensure it’s ready for future touch-ups. My charcoal gray siding has held up beautifully, but I’ve touched up a few spots near the ground where splashback from rain caused minor wear.
Staying proactive keeps your paint job looking fresh for a decade or more.
- Protect Against Wear
Duramax is durable, but you can extend its life by minimizing wear. Trim back shrubs and trees to prevent branches from scraping the paint, and clear debris like leaves from your siding to avoid moisture buildup.
I added gutters to redirect rainwater, which has helped protect my paint from excessive exposure. If you live in a harsh climate, consider applying a clear sealant over Duramax on high-exposure areas like trim.
These small steps reduce stress on the paint, ensuring it stands up to whatever Mother Nature throws your way.
Frequently Asked Questions (FAQ)
Choosing the best exterior paint depends on your climate, surface, and budget. Valspar Duramax is my top pick for its balance of durability, coverage, and affordability. Its FlexShield 365 technology resists cracking and peeling in extreme weather, and the mold-resistant formula is ideal for humid areas. Sherwin-Williams Duration and Benjamin Moore Regal Select are also excellent, offering superior adhesion and premium finishes, but they’re pricier. For wood, Duramax and Duration excel; for brick, Regal Select shines. Test a small area and consider your maintenance commitment before deciding.
Valspar Duramax holds its own against Sherwin-Williams Duration, especially for the price. Both offer exceptional weather resistance and coverage, with Duramax’s FlexShield matching Duration’s PermaLast for crack prevention. Duration applies more smoothly and adheres slightly better to challenging surfaces, but at $70-$80 per gallon, it’s a splurge. Duramax, at $40, delivers near-identical durability and versatility, making it a better value for most homeowners. If you prioritize ease of application and have the budget, Sherwin-Williams edges out; otherwise, Valspar’s a smart choice.
Valspar Duramax dries to the touch in about 1-2 hours under ideal conditions (50-85°F, low humidity). For recoating, wait at least 4 hours, though I’ve found 6-8 hours is safer in humid or cool weather. Full curing takes 7-14 days, during which the paint reaches maximum hardness. Avoid cleaning or exposing the surface to heavy rain during this period. My siding was dry enough to handle the same day, but I gave it a week before washing off some stray pollen.
Pinpointing the longest-lasting exterior paint is tricky, as it depends on surface prep, climate, and maintenance. Consumer Reports suggests Sherwin-Williams Duration and Behr Premium Plus Ultra can last up to 9 years on a well-prepped surface, with Valspar Duramax close behind. In my experience, Duramax’s weather resistance and mold protection make it a contender for decade-long performance, especially on wood and vinyl. Benjamin Moore Regal Select also boasts impressive longevity, particularly on masonry. Proper application and regular upkeep are key to maximizing any brand’s lifespan.

After painting my home with Valspar Duramax, I’m sold on its performance and value. It’s not perfect—its thickness and occasional need for extra coats can test your patience—but the pros outweigh the cons.
