Ask ten painters for the "best" exterior paint and you will get ten answers. The truth is that in New Jersey the brand matters less than three things: choosing the right type of coating for your siding, cleaning and prepping the surface properly, and painting in the right conditions. A premium 100% acrylic exterior paint over a clean, dry, properly prepped surface will outlast a cheap paint every time, and it will also outlast an expensive paint slapped over dirt and mildew. Let's break down what to look for and why.
What NJ weather does to exterior paint
Three local forces shorten the life of an exterior coating here:
- Humidity and mildew. Our summers are muggy, and north- and shade-facing walls stay damp. That grows mildew, which feeds on the surface and leaves black or green staining. Paint has to resist it, and the wall has to be clean before painting or the mildew just grows back under the new coat.
- Freeze-thaw cycling. Water gets into hairline cracks and caulk joints, freezes, expands, and pries them open a little more each winter. A coating that stays flexible moves with the substrate instead of cracking.
- UV and temperature swings. Summer sun fades color and breaks down cheaper binders, while big day-to-night temperature swings make siding expand and contract. Good acrylic paint flexes; brittle paint checks and flakes.
The takeaway: for New Jersey you want a 100% acrylic latex exterior paint with strong adhesion, flexibility and mildew resistance. That is the workhorse category for our climate.
Best paint by siding type
Wood and cedar (clapboard, shakes, trim)
Wood moves a lot with humidity, so flexibility and adhesion matter most. Bare or previously stained wood should be spot-primed (or fully primed) with a quality exterior primer, then finished with two coats of 100% acrylic. Cedar and redwood can bleed tannins, so a stain-blocking primer keeps brown stains from ghosting through a light color.
Fiber cement (HardiePlank and similar)
Fiber cement is stable and takes paint beautifully. A quality acrylic exterior paint holds for a long time here. The key is caulk maintenance at the joints and making sure factory-primed board gets a proper finish coat.
Aluminum and vinyl siding
Yes, you can paint both. Chalky aluminum needs a good wash and a bonding primer. Vinyl must be painted with a paint rated as vinyl-safe in a color no darker than the original, or the siding can absorb heat, warp and buckle. This is one place where the wrong product choice causes real damage, so it is worth getting right.
Stucco and masonry
Masonry wants a breathable acrylic masonry paint (or elastomeric where hairline cracks are an issue) so trapped moisture can escape. Sealing masonry with the wrong coating traps water and leads to peeling and spalling.
Sheen: what to use where
- Siding: flat or low-lustre hides surface imperfections and looks right on a big field of wall.
- Trim, doors and shutters: satin or semi-gloss stands up to handling and sheds dirt, and gives the crisp look most homeowners want on trim.
- Front doors: semi-gloss for durability and a bit of shine.
Why prep beats the paint can
This is the part cheap quotes skip. The best exterior paint in the world will peel in two summers if it goes onto a dirty, chalky or mildewed surface. Before we paint an exterior we usually soft wash the house so paint bonds to clean siding instead of to mold and residue. Then we scrape loose paint, sand rough edges, spot-prime bare wood, and re-caulk the joints that let water in. We cover why this order matters in power washing before painting. Skip that work and no premium coating can save the job.

What we use
We put Benjamin Moore® exterior lines on the wall, matched to the substrate: acrylic exterior finishes for wood, fiber cement and previously painted siding, stain-blocking primers where bleed-through is a risk, and vinyl-safe products where the siding calls for it. Good paint covers in fewer coats, keeps its color longer and resists the mildew our climate throws at it. Paired with real prep, that is what earns a coating that holds for years instead of seasons, and it is why we can stand behind exterior work with a 1 year warranty.
Paint vs stain on wood siding and trim
If your home has natural wood siding, cedar shakes or a wood-clad area, you have a choice between paint and stain, and it changes the maintenance story. Paint forms a film on top of the wood; it gives you the widest color range and the longest interval between recoats, but when it does fail it tends to peel and needs scraping. Stain soaks into the wood; it shows off the grain, will not peel the same way, and is easier to refresh, but it fades faster and needs recoating more often, especially on sun-exposed and horizontal surfaces. In our climate, most homeowners paint their main siding and trim for longevity and use stain where they want the wood to show, such as a front door, a pergola or a deck. Whichever you choose, the surface still has to be clean and dry first.
Don't skimp on primer and caulk
Two of the least glamorous materials do the most for how long an exterior job lasts. The right primer seals bare wood, blocks tannin and stains from bleeding through, and gives the finish coat something to grip. The right caulk (a quality paintable acrylic or siliconized acrylic) seals the joints where water tries to get in around trim, windows and corners, which is exactly where freeze-thaw damage starts. Cheap caulk shrinks and cracks within a couple of winters. Spending a little more on these two behind-the-scenes materials pays off every year the coating holds.
Quick checklist for choosing exterior paint in NJ
- 100% acrylic latex for the flexibility our freeze-thaw winters demand
- Mildew-resistant finish for humid, shaded walls
- The right primer for your substrate (stain-blocking on cedar, bonding on aluminum)
- Vinyl-safe product and color if you have vinyl siding
- Breathable coating on stucco and masonry
- Clean, dry, prepped surface before a drop of paint goes on
