Benjamin Moore Aura Interior Paint Review: The Spec Sheet

Benjamin Moore Aura Interior is the brand's top interior wall paint: a self-priming, 100% acrylic waterborne paint sold in Matte, Eggshell, Satin and Semi-Gloss, with Color Lock technology, a one-hour recoat and less than 50 g/L of VOC. Its own data sheets rate it at 350 to 400 sq ft per gallon in Matte, Eggshell and Satin (400 to 450 in Semi-Gloss), a lower spread rate than Regal Select because each coat is meant to go on thicker: about 1.9 to 2.2 mils of dry film in Matte. Benjamin Moore's US product pages showed $108.99 a gallon on October 27, 2026, against $84.99 for Regal Select. On paper it earns its price for deep and saturated colors, drastic color changes and walls that get washed often; for a light neutral in a bedroom, Regal Select or Sherwin-Williams Emerald Interior come close on most specs.

How this review works: every figure comes from the makers' data sheets, brochures and product pages, read on October 27, 2026. Calculations made from them are ours and labeled as such. No paint was applied for this page.

Aura Interior at a glance: what the data sheets say

Benjamin Moore publishes one technical data sheet per sheen: Matte N522, Eggshell N524, Satin N526 and Semi-Gloss N528. The four share the same platform: proprietary 100% acrylic vehicle, titanium dioxide pigment, Gennex colorants, four tint bases (1X to 4X), touch dry and recoat in 1 hour at 77°F and 50% relative humidity, application between 50 and 90°F, and VOC under 50 g/L. What changes from one sheen to the next:

The sheets also list CDPH emissions certification, an antimicrobial additive that inhibits mold and mildew on the paint film surface, and third-party testing against the Green Seal GS-11 (2015) criteria. The Aura Interior Matte product page adds gallon and quart sizes, "1 or 2" coats and the $108.99 gallon price. Neither the page nor the data sheet states a warranty term: if one matters to you, ask the retailer for it in writing.

Color Lock, Gennex and the resin: what Benjamin Moore claims

The Aura Interior brochure rests the product on three technologies and says Aura is the only paint to combine all three:

• Color Lock. Benjamin Moore describes it as embedding pigment within the binder molecules, where a standard paint holds pigment loosely, so color is locked into the film for fade resistance. The practical claim that follows is no color rub-off: the brochure shows a dry sponge rubbed over Aura in Van Deusen Blue HC-156 coming away clean.
• A proprietary acrylic resin. Benjamin Moore's May 2022 announcement of the reformulated Aura Interior credits a new resin with smoother application across all sheens and a film that resists scuffs, stains and color rub-off. The brochure adds that color and sheen stay intact after scrubbing and calls it the brand's "most scrubbable" paint.
• Gennex colorants. Aura is tinted only with Gennex waterborne colorants (the data sheet forbids adding anything else), which Benjamin Moore says avoids the chemicals in common colorants that weaken paint. Aura is sold and tinted by Benjamin Moore retailers, in more than 3,500 colors.

These are the maker's claims, illustrated with lab panels rather than published test numbers. The data sheets do allow one objective comparison: Regal Select, the tier below, also uses Gennex colorants and a proprietary 100% acrylic vehicle, but lists a "proprietary stain release technology", not Color Lock. The extra money buys Color Lock and a thicker film per coat.

Why Aura covers fewer square feet than Regal Select

It looks like a paradox: the premium paint, sold on "remarkable coverage", is rated for fewer square feet per gallon. The arithmetic explains it. A US gallon is 231 cubic inches, so spread 1 mil (one thousandth of an inch) thick it covers about 1,604 sq ft. The dry film left behind is the wet film multiplied by the volume solids. Applied to the published figures (our calculation):

1,604 divided by 4.6 mils gives 349 sq ft and divided by 4.0 gives 401: exactly Aura's 350 to 400. At the middle of each range, a coat of Aura Matte leaves roughly 2.05 mils of dry paint against 1.6 for Regal Select Matte and for Emerald Matte, about 28% more film per coat (Emerald goes on at 4 mils wet too, but with 41% solids instead of 47%). That is what Benjamin Moore's "extreme hide" means in numbers: not more area per gallon, but more paint per pass.

Two cautions. Benjamin Moore still recommends two coats on bare surfaces "to achieve full color development", one or two on previously painted walls. And certain custom colors may need a Deep Base Primer tinted to a special formula: see our interior primer guide, and the interior paint coverage calculator guide for quantities on any paint.

Aura vs Regal Select vs Sherwin-Williams Emerald Interior

Regal Select is Benjamin Moore's tier below Aura; Emerald Interior is Sherwin-Williams' top interior acrylic and Aura's closest cross-brand rival. Regal Select figures come from its data sheets (Regal Select Matte N548 product page and TDS), Emerald figures from the Emerald Interior Matte product data sheet and the Emerald Interior product page.

Aura or Regal Select? Both are self-priming acrylics with the same colorant system and the same CDPH certification. Regal Select spreads further, offers a true Flat, and costs $24 less per gallon on Benjamin Moore's site. Aura adds Color Lock, roughly 28% more dry film per coat in Matte, and a one-hour recoat in every sheen. Choose Aura for saturated or dark colors, a big jump in color, or walls that will be scrubbed; choose Regal Select for light and mid-tone colors in normal-traffic rooms.

Aura or Emerald Interior? The spread rates are identical. Aura recoats in 1 hour against 4, uses a 100% acrylic vehicle rather than styrene acrylic, and lays a thicker dry film in Matte; Emerald comes with a written lifetime limited warranty and GREENGUARD Gold certification, and is sold in Sherwin-Williams stores. Our Sherwin-Williams Emerald Interior review covers that side in detail, and the Sherwin-Williams vs Benjamin Moore interior comparison compares the two brands beyond their flagships.

Which Aura sheen for which room

The brochure assigns each sheen a use: Matte for ceilings, low-traffic walls and bedrooms; Eggshell and Satin for high-traffic walls, hallways, closets, living rooms, kitchens and bathrooms; Semi-Gloss for cabinets, doors and trim. Two details matter when comparing brands:

• Sheen names do not match across brands. Sherwin-Williams measures Emerald Satin at 85° and gives 10 to 20 units, the same angle and almost the same range as Aura Eggshell (10 to 22). On paper, Emerald Satin sits closer to Aura Eggshell than to Aura Satin. At the glossy end, Emerald Semi-Gloss is 35 to 45 units at 60°, Aura Semi-Gloss 50 to 60: the Aura is shinier.
• Aura Matte is washable but still a matte. At 3 to 6 units at 85° it is close to Emerald Matte (4 to 8). Benjamin Moore's "most scrubbable" claim applies to the line, yet its own brochure keeps Matte for low-traffic walls and bedrooms and sends hallways and kitchens to Eggshell or Satin.

For trim, doors and cabinets, a dedicated enamel often makes more sense than any wall paint in semi-gloss; our guide to painting interior doors, trim and baseboards covers the choice, and our Benjamin Moore Advance cabinet paint review sets Benjamin Moore's waterborne alkyd enamel against Aura Semi-Gloss for kitchen cabinets. The general rules on sheen are in our interior paint finish guide (flat, eggshell, satin).

Drying, recoat and cure: the one-hour recoat in practice

Aura recoats after 1 hour at 77°F and 50% relative humidity, in all four sheens; Regal Select asks for 1 to 2 hours (3 for Semi-Gloss) and Emerald Interior for 4. On a one-day bedroom repaint, that is a second coat before lunch rather than late in the afternoon. Cool, humid air stretches every time, and none of the three should be applied below 50°F.

Fast drying has a cost: less time to blend a wet edge. Benjamin Moore lists "extended open time" among Aura's features, but its data sheet also allows up to 8 fl oz of Benjamin Moore 518 Extender or water per gallon "to adjust open time". The brochure recommends a shed-resistant white woven or microfiber roller cover with a 3/8 in nap and an extra-firm 2 or 2½ in angled nylon-polyester sash brush for cutting in. The data sheet's instruction is to apply generously, from the unpainted area into the wet area: in practice, one wall at a time, from corner to corner. Recoat time is not cure time: Benjamin Moore says Aura surfaces can be washed after two weeks. Our interior paint drying time guide explains the difference between dry, recoat and cure.

How many gallons for a room, and what it costs

A worked example (our calculation): a 12 by 14 ft bedroom with 8 ft ceilings has 416 sq ft of wall. Take off one door and two windows, about 50 sq ft, and two coats come to roughly 730 sq ft.

Both lines round up to two gallons here, so the real difference is the price gap: about $48 for this bedroom. Per square foot and per coat, Aura costs about 45% more than Regal Select at the middle of each spread-rate range. Retailers set their own prices, so treat these as a dated reference.

Aura Bath & Spa: the bathroom version

Aura Bath & Spa (product 532) is a separate formula, sold in Matte only (3 to 4.5 units at 85°). Its data sheet describes it as optimized for high-humidity rooms, with Color Lock, a mildew-resistant coating and zero VOC. It covers the same 350 to 400 sq ft per gallon, recoats in 1 hour, and asks for at least 24 hours before the room returns to full service. The product page showed the same $108.99 per gallon. The mildew resistance is about the paint film surface; it does not replace an exhaust fan. Our mold-resistant bathroom paint guide compares it with Duration Home, Emerald and Perma-White.

VOC, emissions and safety

Aura Interior is under 50 g/L of VOC and CDPH Emissions Certified, a reference to the California Department of Public Health's emissions test method. Emerald Interior carries GREENGUARD Gold, which UL describes as a certification with even lower VOC emission limits for sensitive groups that also requires the California chamber method (UL, GREENGUARD certification). Low VOC still means ventilating: the EPA notes that many VOCs run up to ten times higher indoors than outdoors and advises more ventilation when using products that emit them (EPA, VOCs and indoor air quality). Our low-VOC interior paint guide compares certifications across brands.

In a home built before 1978, the old paint under your walls and trim may contain lead. Aura's data sheet carries the standard lead warning; before scraping or sanding, follow the EPA's lead-safe practices for do-it-yourselfers.

Aura Interior vs Aura Exterior

Same name and Color Lock idea, but separate products with separate data sheets. For siding, trim and doors outside, read our Benjamin Moore Aura Exterior review; for colors indoors, our Benjamin Moore interior paint colors guide.

Who should buy Aura Interior, and who can skip it

• Buy it for deep and saturated colors. Navy, charcoal, deep green and jewel tones are where Color Lock (no rub-off) and the thicker film per coat matter most.
• Buy it for a drastic color change. Light over dark or dark over light: more dry film per coat is the spec that helps. Keep a tinted primer in mind for the hardest custom colors.
• Buy it when time counts. A one-hour recoat in every sheen.
• Buy it for walls that get washed: hallways, kids' rooms and kitchens, in Eggshell or Satin.
• Skip it for a light neutral in a quiet room. A pale greige in a guest bedroom gains little from Color Lock; Regal Select spreads further for $24 less per gallon.
• Think twice for ceilings. Benjamin Moore lists Aura Matte for ceilings, but a dedicated ultra flat ceiling paint is the more usual choice overhead; see our Benjamin Moore Waterborne Ceiling Paint review.
• Look elsewhere if you want a written lifetime warranty on the label. Emerald Interior states one; Aura's pages do not.
