Sherwin-Williams Cashmere vs. Duration: Which Interior Paint Wins?
Sherwin-Williams makes the choice feel simple: Cashmere for beauty, Duration for toughness.
But both are self-priming, both carry 1,700 plus colors, and both dry to recoat in a few hours. The real question is which trade-off fits your room.
That trade-off is sharper than most people expect.
Short answer: Choose Cashmere for living rooms and ceilings where a silky, flawless finish matters most. Choose Duration for kitchens, bathrooms, and high-traffic walls that need moisture resistance and long-term durability. One thing to weigh: Duration covers only 250 to 300 square feet per gallon versus Cashmere’s 350 to 400. So Duration’s higher sticker price shrinks once you factor in coverage.

Where They Are the Same
Both paints share more common ground than their price difference suggests.
Each is self-priming, which saves a full coat on most surfaces.
Both carry the same massive color library: 1,700 plus shades, the same palette you browse in any Sherwin-Williams store. VOC levels are low on both, under 50 g/L, and each dries to recoat in a few hours.
For low-traffic interior walls, either paint will look great for years.
The Differences That Decide It
Coverage
Cashmere spreads further: 350 to 400 square feet per gallon. Duration is thicker and covers 250 to 300.
On a large room, that gap can add a whole extra can of Duration. Factor it in before comparing sticker prices directly.
Durability and Moisture
Duration is in a different class for toughness.
Its PermaLast technology builds a film about 70 percent thicker than a standard coat. That extra build resists scrubbing, scuffs, and repeated cleaning far better than Cashmere.
Duration also adds Moisture Resistant Technology. Cashmere offers standard moisture protection, fine for dry rooms but not for steam or splashes.
Washability follows the same split: excellent on Duration, good on Cashmere.
Finish and Application
Cashmere is the easier paint to work with. It levels beautifully, leaves no brush marks, and feels forgiving even for a first-time roller.
Duration is thicker and heavier in the can. It takes more effort to spread evenly. A skilled painter handles it easily, but beginners may notice.
Cashmere also offers more finish options, including Eg-Shel and Low Lustre, which Duration does not carry.
Price
Cashmere runs around $70 to $75 per gallon. Duration runs around $80 to $85.
That gap looks small until you account for coverage. Because Duration covers less area per gallon, a whole-room job can cost more than the per-gallon price implies. Run the math for your square footage first.
Which Paint Goes Where
Room type is the best guide to which paint earns its cost.
Cashmere shines in low-traffic spaces where finish quality is the priority. Living rooms, dining rooms, bedrooms, and ceilings all suit its smooth, forgiving film.
Duration belongs anywhere moisture or wear are real concerns. Kitchens, bathrooms, laundry rooms, and busy hallways are where its thicker film and moisture resistance pay off.
Painting a whole house? A practical split is Cashmere on bedroom and living-area walls, Duration in the wet and high-wear rooms.
The Bottom Line
- Choose Cashmere if you want the smoothest, most forgiving finish at a lower price per gallon, for low-traffic walls and ceilings where looks matter more than scrub resistance.
- Choose Duration if your room sees moisture, heavy use, or frequent cleaning. Its thicker film and moisture resistance make it the better long-term pick in kitchens, baths, and high-traffic areas.
