AristoshieldDunn-Edwards paint review

Why it happens. The film that flows out beautifully off a brush does not always level the same way through a tip. This is the single most repeated complaint from cabinet refinishers, and the fact that several experienced sprayers hit it says the spray window is narrower than the brush window.

The fix. Airless at 1,800 to 2,500 psi, starting at the low end and only climbing if the fan tails, with a .013 to .015 tip. Lay a full 4.0 wet mils in one pass and check it with a wet-film gauge on the first door rather than under-applying and chasing it with a heavy second pass. Spray one door, let it sit overnight, and look at it in raking light before you pull the rest of the kitchen apart.

Why it happens. Chalking is the resin binder breaking down under UV and releasing loose pigment as a powder. It is an exterior exposure failure, and it shows up when a coating spends years in direct sun on broad flatwork. The reports cluster where people rolled a trim-and-metal enamel across sun-baked exterior walls or a south-facing deck plane.

The fix. Match the product to the surface. Aristoshield is built for doors, trim, railings, and metal, which are usually shaded, vertical, or small. For exterior siding and wall flatwork, Evershield is the correct Dunn-Edwards product.

Why it happens. The data sheet allows direct-to-metal application only on properly prepared plain steel. Galvanized is explicitly excluded, because zinc surfaces react with paint films that are not formulated for them and the failure shows up months later.

The fix. Prime galvanized with Ultrashield Galvanized Metal Primer (ULGM00) first, and prime other non-ferrous metal with Ultrashield, Bloc-Rust, or Super-Loc. On plain steel, one coat of Bloc-Rust Premium under two coats of Aristoshield is what Dunn-Edwards recommends for the best corrosion protection. One gallon of primer up front is cheap next to redoing a garage door.

Why it happens. Blacks and deep blues over a tinted gray primer build to full opacity slower than a mid-tone. The published coverage numbers hold for normal colors, not for the dark end of the deck.

The fix. Plan a third coat and buy the extra gallon up front. If you are ordering online, that matters more than usual, because online paint orders cannot be returned and a second order arrives days later.

Why it happens. Not a bad batch. The 65 to 80% gloss reading for semi-gloss is measured at 14 days, and the shine keeps climbing as the film cures.

The fix. Wait. Judge the sheen at two weeks, and do not add a corrective coat in week one chasing a shine that is still coming.

On trim, doors, and cabinets where the finish reads at arm's length, yes. The urethane-alkyd leveling lays down smoother than commodity acrylic enamel, and the cured film takes a knock better. On walls or low-touch surfaces it is overkill. Use a standard wall paint there and save the $30 a gallon.

Yes. It is not self-priming. Dunn-Edwards specs a substrate-matched primer: Vinylastic on new drywall, Decoprime on bare wood, Bloc-Rust or Enduraprime on ferrous metal, and Ultra-Grip on slick or factory-finished surfaces. On sound previously painted trim that has been scuff-sanded and deglossed you can sometimes go straight to topcoat, but on glossy or bare substrates, prime.

They are close cousins, both waterborne alkyds aimed at a near-sprayed brush finish. Advance has the bigger fan base and a deeper color deck nationally. Aristoshield levels comparably, claims stronger yellowing resistance, and adds genuine direct-to-metal use that Advance is not built for. Availability decides it: Advance if you are far from a Dunn-Edwards store, Aristoshield if you are in the Southwest.

On properly prepared plain steel, yes, two coats and no primer, which is why it shows up on wrought-iron railings, garage doors, and handrails. Prepared means clean, sanded, and rust-treated. The data sheet is narrower than the marketing: for the best corrosion protection Dunn-Edwards wants one coat of Bloc-Rust Premium under two coats of Aristoshield, galvanized steel must be primed with Ultrashield first, and other non-ferrous metals need a primer too. The zinc phosphate in the formula is why the steel claim holds up.

No. The data sheet allows direct-to-metal application only on properly prepared plain steel and explicitly says not to apply it directly to galvanized. Prime galvanized with Ultrashield Galvanized Metal Primer first. This catches people out often, because galvanized is what garage doors, gutters, and a lot of fencing are made of, and the failure shows up months later as sheets of coating peeling clean off.

The urethane-alkyd resin is durable and flexible enough to handle UV and temperature swings outdoors while staying hard enough for indoor trim. That crossover is the selling point. One product covers a porch door, an exterior handrail, and the interior trim in the same house. Most premium trim enamels are interior-only.

At the Dunn-Edwards online shop it runs $92 to $102 a gallon depending on sheen, with quarts at $27 to $28. In-store pricing at Dunn-Edwards locations is typically lower, around $75 to $85 a gallon before contractor discounts. Online orders ship free over $50 but are non-returnable, and the listed price already includes the PaintCare recycling fee in participating states.

Yes. Dunn-Edwards specs airless spray at 1,800 to 2,500 psi with a .013 to .015 tip, laid down at 4.0 wet mils per coat. It is designed to go on unthinned; if it drags, add at most 4 fl oz of clean water per gallon. Some cabinet refinishers report orange peel on sprayed panels, so spray a test door and adjust tip and technique before committing to a full cabinet set.

There are four: Eggshell (ASHL30, 10 to 15% gloss at 60 degrees), Low Sheen (ASHL40), Semi-Gloss (ASHL50, 65 to 80% gloss measured at 14 days), and High Gloss (ASHL70). Coverage moves with the sheen, so eggshell stretches to 350 to 425 sq ft a gallon while semi-gloss lists 325 to 375. Semi-gloss is the usual pick for trim, doors, and cabinets. High gloss is spray-only territory and costs about $10 more a gallon.

It reaches HB pencil hardness after a 7-day cure per ASTM D3363, with scrub resistance over 4,000 cycles and an Excellent block-resistance rating, so doors do not stick to weatherstripping after an overnight close. It is touch dry in 45 minutes to 2 hours depending on sheen and recoats in 4 to 6 hours, but treat the film gently for the first couple of weeks while it builds full hardness.

If the project is cabinets and only cabinets, Decoglo is the better tool at about $81. It is built for interior cabinets, doors, and trim, cures in about 7 days, and self-primes on most sound repaints. Choose Aristoshield when the same job also has hand-brushed trim, an exterior door, a metal railing, or a true high gloss on the list.
