Specs reflect current Sherwin-Williams interior lines; prices vary by region and sales.

These are both top-shelf paints.

Both come in flat, matte, satin, and semi-gloss, with 1,700-plus colors and built-in primer.

Both are washable, block stains, and resist mold and mildew. Both have exterior lines too.

The differences are coverage, film, and moisture.

This is the biggest gap.

Emerald covers 350 to 400 square feet per gallon. Duration covers about 250 to 300.

So you may need fewer gallons of Emerald. That narrows the gap with Duration on price.

Duration uses PermaLast, which builds a film about 70 percent thicker. It is made to last.

Emerald counters with a harder film that resists dirt and stains especially well. Both are very durable.

For damp rooms, Duration has the edge.

Its Moisture Resistant Technology suits bathrooms and humid spaces. Emerald fights mildew too, just not as far.

Emerald runs about $85 to $90 a gallon. Duration is a touch less at $80 to $85.

But Emerald covers more, so the real cost per wall is closer than the sticker suggests.

Pick by room.

For most walls, kitchens, and high-traffic spaces, Emerald wins on coverage and a hard finish, so it is the default.

For bathrooms, laundry rooms, and other damp spots, Duration brings moisture resistance and a thick build that are worth it.

Choose Emerald if you want the hardest finish, the best coverage, and an all-around premium wall paint for most rooms.
Choose Duration if you are painting a bathroom or damp space, or you want the thickest film at a slightly lower price per gallon.
