Aura ExteriorBenjamin Moore paint review

Why it happens. The most expensive mistake I see is a homeowner buying a $95 gallon and treating the prep like an afterthought. The Color Lock film cannot grip a surface that is letting go underneath it. I have gone back to houses where the owner blamed the paint and the real problem was three layers of failing old latex that nobody scraped.

The fix. Scrape the loose and peeling. Sand the chalky and the glossy. Wash off the mildew with a bleach solution and let it dry. Prime the bare spots. Caulk the gaps last, after primer and before topcoat. Aura does not fix bad prep, and nothing does.

Why it happens. Tannins. Self-priming is a coverage claim, not a substrate claim, and the can is quiet about the difference. Raw cedar and redwood push tannin through an unprimed topcoat inside a season.

The fix. Stain-blocking primer on the bare wood first, then two coats of Aura. Same logic elsewhere: bare masonry wants a masonry primer, and chalky old paint wants a binding primer or the whole system releases.

Why it happens. Premium and self-priming get read as one coat. Not on a color change, not on a faded wall. One coat looks fine the day you finish and gives itself away the first sunny morning.

The fix. Two coats. Always two coats. Buy a gallon more than your math says so you are not chasing a partial gallon on a Sunday when the dealer is closed.

Why it happens. Benjamin Moore has updated the Aura Exterior formula, and in two separate contractor groups painters are independently reporting the same thing on glass-adjacent hard surfaces: work prepped exactly the way they always prepped it, letting go in small patches within a year. One painter says the new formulation failed hard on windows sitting next to four-year-old work in the old paint that is still tight. That is a couple of forum posts, not a recall.

The fix. If it is your own house and the prep is right, buy it anyway — the color hold is still the best in the tier. If you are a pro putting your name on window sash this season, do a small section first and come back to it in a month before you commit a whole house.

On a forever home, yes. The color holds in direct sun longer than anything in the tier and the film resists chalking. On a flip or a rental you will sell in five years, no. Regal Select Exterior is most of the paint for $25 less a gallon. Pay the premium when you plan to live with the result for a decade, not a sale cycle.

On sound, previously painted siding in good shape, no — it self-primes there. On bare wood, chalky old paint, bare masonry, or tannin-bleeding cedar and redwood, prime first. Self-priming is a coverage claim, not a substrate claim. Skip the primer on raw cedar and the tannin bleeds through in a season.

On prepped, primed wood or fiber cement, plan on 10 to 15 years before a full recoat in most climates. South and west walls fade first. Trim takes the weather harder than the field and may want a touch-up before the body does. Prep is what decides this, not the can.

They are the two best homeowner-grade exterior acrylics on the market and they trade blows. Aura holds deep color slightly better and brushes a touch smoother. Emerald has a marginally tighter early dirt-shed and a self-cleaning story. Buy whichever dealer is closer — the 10-minute drive matters more than the spec sheet difference.

Two, on any color change and on any faded wall. Self-priming and premium get read as one coat, and one coat looks fine the day you finish and shows the old color by the next bright morning. Budget the gallons for two full coats, plus a spare.

Enough to sample, not enough to change paint. Painters in two separate contractor groups report the new can letting go in small isolated patches inside the first year on glass-adjacent hard surfaces like window sash, on work they prepped the way they always have. That is a couple of forum posts, not a recall. On your own house with proper prep, buy it. On a paying job full of sash, do a test section and come back to it in a month.

Low Lustre (N634) is the volume seller for siding and the safe default — it sheds dirt and washes down better than the Flat. Soft Gloss (N632) goes on trim and doors. Flat (N629) hides board imperfection but cleans the worst of the four.

No. If you bought an Aura Interior gallon for the porch ceiling, take it back. The resin is built for inside, and the exterior line exists because outside is a different problem.

Yes — quart, gallon and 5-gallon. For a whole house the bucket saves a few dollars a gallon and one trip, and it keeps the tint consistent across a long wall. Order it boxed from one tint run.
