Why is Paint so Expensive?

Why a gallon of paint can cost anywhere from $35 to $140 — what’s happening inside the can, the chemistry of pigments and binders, and what that means for the wall behind your couch.

Not all paint is created equal. If you’ve ever stared at a wall of paint cans ranging from $35 to $140 a gallon, you’ve probably wondered what the difference is. Why does one cost four times as much?

The difference isn’t just in the price tag. It’s in how many coats you’ll need, how long it’ll last, how good it’ll look, and how much it’ll cost you in the long run. Here is the chemistry-level comparison of the three big players: Home Depot’s Behr and Glidden, Sherwin-Williams, and Benjamin Moore.

1. Coverage: How many coats are you willing to roll?

Home Depot (Behr & Glidden)

Coverage rating

5/10

Budget-friendly, yes. Efficient, no. Expect two to three coats to achieve an even finish, and four to five coats over a dark color or a textured wall.

Why it’s cheap: low volume of solids. Solids are the pigments and binders that give paint its opacity. Pigments provide color, but budget paints typically use lower-quality pigments or fewer of them, leading to thinner coverage. More coats means more time, more labor, and more gallons.

Sherwin-Williams (SuperPaint & Emerald)

Coverage rating

8/10

Significantly better coverage. Two coats is the standard, and one coat is achievable on a similar base color. Pigments are more refined and adhere well to a variety of surfaces.

Why it’s better: a higher concentration of solids and premium pigments like titanium dioxide (TiO₂), which provides superior hiding power and brightness.

Benjamin Moore (Aura)

Coverage rating

10/10

One-coat coverage is the standard, not the exception, even over dark colors. Aura’s proprietary Color Lock technology bonds pigments at a molecular level for rich, pigment-dense, even color.

2. Durability: How long will it last?

Home Depot (Behr & Glidden)

Durability rating

6/10

For a rental property or a space you don’t care too much about, fine. But within two to three years expect chipping, peeling, and fading — especially in high-traffic areas or exterior surfaces exposed to the elements.

Why it’s cheap: budget paints rely on low-cost binders like vinyl acetate, which are responsible for adhesion and flexibility. These binders are prone to cracking and peeling, and UV exposure causes faster fading because the pigments themselves are lower quality.

Sherwin-Williams (Duration & Emerald)

Durability rating

8/10

Five to eight years of vibrant, intact color and solid protection against the elements. The high-grade acrylic binders are more flexible, more UV-resistant, and form a tighter film — so the paint resists cracking, peeling, and chipping. Some lines are mildew-resistant, which is excellent for bathrooms and kitchens.

Benjamin Moore (Aura & Regal Select)

Durability rating

10/10

Ten-plus years of beauty. The resins form a cross-linked polymer network, making the paint resistant to wear, moisture, and extreme temperature changes.

3. Finish: Smooth or patchy?

Home Depot (Behr & Glidden)

Finish rating

3/10

Visible roller marks and brush strokes. The sheen tends to look dull or flat. Why it’s cheap: budget formulations have weaker flow and leveling characteristics, leading to uneven film formation and inconsistent sheen.

Sherwin-Williams (SuperPaint & Emerald)

Finish rating

8/10

Smooth, consistent, professional-looking. The high-performance acrylic polymers create a smoother film that resists drips, roller marks, and brush strokes.

Benjamin Moore (Aura & Regal Select)

Finish rating

10/10

Flawless. Deep, rich, and smooth. Aura’s superior leveling, high viscosity, and flow properties produce a silky finish with no visible roller marks or brush strokes.

4. Washability: Can it survive the scrub test?

Home Depot (Behr & Glidden)

Washability rating

5/10

Scrub too hard and you’ll scrub the color off the wall. Weaker film strength and lower scrub resistance is the trade-off for the lower price.

Sherwin-Williams (SuperPaint & Duration)

Washability rating

8/10

Wash without fear. Enhanced film strength and high-performance acrylic binders let the paint survive frequent cleaning without losing color or finish. (Yes — the same acrylic family used in salon nails.)

Benjamin Moore (Aura & Regal Select)

Washability rating

10/10

Built for scrubbing. Aura’s cross-linked polymer structure resists staining and can be scrubbed clean without losing color or sheen — ideal for high-traffic areas and families with kids.

5. Environmental impact: VOC levels matter

Home Depot (Behr & Glidden)

Environmental rating

6/10

Budget paints still contain high VOCs that are released as the paint dries and contribute to indoor air pollution.

Sherwin-Williams (SuperPaint & Emerald)

Environmental rating

8/10

Most Sherwin-Williams paints are low-VOC and the acrylic binders make them safer for use in homes with children or pets.

Benjamin Moore (Aura & Regal Select)

Environmental rating

10/10

Often zero-VOC. Aura uses waterborne alkyd technology to deliver durability without sacrificing sustainability — an eco-friendly choice for homeowners who care about indoor air.

What’s the real cost?

Cheap paint costs less per gallon and more over time.

  • More coats = more paint = more labor.
  • Poor durability = more frequent repaints.
  • Inferior finish = your home doesn’t look as good as it could.

Premium paints cost more upfront, but they save you time, money, and headaches over the life of the finish.

Final thoughts

You get what you pay for. If you want a home that looks stunning, lasts for years, and holds its value, skip the bargain bin and invest in quality. We use the best because your home deserves it.
